1 About GPS Navigation This GPS receiver is a precision navigation instrument utilizing the latest technology available today to provide optimum performance from the GPS satellite and Beacon land signals received. As with all other forms of radio signals, the ultimate navigation result is dependent upon the quality of these signals. Radio signals may, on occasion, be distorted, jammed, or otherwise incorrect.

2 Functional Description The MX510 and MX512 Navigation CDU models are generally described in this manual as MX51x Control and Display Unit (CDU). Their general operating features are identical and will be described in common details in this manual. Specific model number will be called in areas where they differ from one another. CDU Configurations The MX510 and MX512 Navigation System is available in several configurations.
MX51x BR Beacon and Remote Configuration MX51x/BRIM (Backup Receiver Integrity Monitor) The MX51x/BRIM is an enhanced Dual-Control configuration wherein two MX51x CDUs and two MX521A smart DGPS antennas are supplied. The two MX51x units are connected in dual-control configuration but they operate as independent navigator units with dedicated antennas. The Integrity Monitoring (IM) feature is a software option that works in the MX51x CDU hardware.
3 DGPS Beacon System As Maritime Safety Administrations, Navy, and Coast Guard Organizations realize the limitations of standard GPS positioning, many have begun installing DGPS Beacon Stations. While an understanding of this system is not necessary for operating receivers with internal beacon receivers, you may want to read on to have a better understanding of how your receiver is capable of achieving the high levels of accuracy made possible by this network of transmitters.
Blank page 16 | DGPS Beacon System
4 Keypad & Display Description The MX510 and MX512 keypad operation and traffic light indications are identical. The Traffic Lights on the right side of the display will tell you how your navigator is operating. You need to take care in reading the traffic light indications, as there are overlapping possibilities between the GPS and DGPS modes. If you are unsure of the current operating mode, select the CFG function key and scroll down to the DGPS selection.
Yellow/Green Solid GPS position update; DGPS corrections are not being received. You may see this from time to time during normal operation. It usually occurs when the beacon signal is not available (either it is being blocked by terrain or a local object or you are out of range of the transmitter) and/or you are tracking 3, 4, or 5 satellites, and the satellites have poor geometry relative to your position. The condition will normally go back to green solid, when it picks up another beacon station.
Green Solid GPS position update with HDOP value less than 4. This is the normal operating condition. Position accuracy is normally between 3 to 5 meters, but can be out as much as 30 meters. Keep in mind that position accuracy is always only as good as the geometry of the satellites and the navigation information provided by the satellites. This is the normal operating condition and no icon will be displayed. The Display: The MX51x uses a 6.4” monochrome quarter VGA LCD display.
The Function Keys: The MX51x has 17 function keys. These keys are used to directly access various navigation, positioning, GPS, configuration and other screens. One function key is used to mark your present position, and to activate the Man-Over-Board feature when depressed for a few seconds. The ten function keys with alphanumeric designations are described in the following chapters. The MARK/MOB keys and the GOTO keys are described below.
GOTO This function key allows you to quickly create a route from your present position to waypoint or a route. This single waypoint route can use an existing waypoint from the Waypoint Bank, or you can quickly create one by either defining the appropriate coordinates or specifying a range and bearing. Be careful when you use this selection, as it will erase your current active route when it creates the new one.
FUNCTION Keys You might have noticed that above and below each primary function key are numbers and letters. These numbers and letters are used when you are in the edit mode. You will find that they are most often used in the RTE, WPT, and CFG screens, but they are used in other screens as well. If you are trying to enter text, simply locate the desired letter and press the appropriate function key repeatedly until the appropriate letter or number appears.
•• GPS Offset - sets an offset for calculating the GPS antenna position if you can’t physically locate the antenna exactly where you want it (e.g. over the centerline of the boat).
Waypoint Bank (WPT1) where a symbol is used as the first character of the waypoint description. The Panorama and Plot screens will automatically place these navigation markers on the screen as you approach them. The degree values that you see are your Course Over Ground (COG), as calculated by the GPS receiver’s position fix to position fix, and Bearing (BRG) from your present position to the waypoint. The speed value is your Speed Over Ground (SOG) as calculated by the GPS.
NAV2 - Basic Steering Information The NAV2 screen provides the bearing (BRG) and range (RNG) to the waypoint you are approaching in large bold characters. Below these, you will see your actual Course Over Ground (COG) and Speed Over Ground (SOG). The bottom portion of the screen provides cross-track error information. Again, if you don’t see the information described here on your screen, you will need to create a route in RTE1 first (refer to the Route section of the manual).
NAV4 section which follows. You will find the right hand window to be a helpful tool. In addition to identifying the waypoint you are currently approaching, it identifies the waypoint at the end of the next leg. The really unique feature of this screen is the graphical representation of your actual course line approach angle relative to the next leg of your course. This approach angle is continuously updated in real time and will help you setup for course changes.
data to calculate your speed parallel to wind and can output the VPW NMEA 0183 data sentence to other on-board instruments. The window below the wind data provides information relating to your course and speed. You will find the Course Over Ground (COG calculated by the MX421 smart GPS antenna), Heading (HDG, your NMEA 0183 compass input), and Heading To Steer (HTS) data on the left side of the window. HTS data is calculated by considering your Heading, minus COG and adding BRG to the waypoint.
NAV5 - Compass Display Screen The NAV5 screen displays the Heading and Rate of Turn values of the MX575 Satellite Compass (or Gyro) in digital and compass row formats. In addition, it also displays the position, COG, SOG, BRG, and RNG. This screen can be accessed by pressing the NAV key repeatedly until you reach the desired NAV screen. NAV6 - Compass Display Screen The NAV6 screen displays the Heading and Rate of Turn of the MX575 in large digital and tape measure style readouts.
2 The RTE2 screen provides storage space for up to 100 user defined routes. You can pre-define routes, or copy new routes from the RTE1 (active route) screen. Later you can choose individual routes or link two or more routes in the RTE1 screen (refer to Creating a Multi-Waypoint Active Route section of this manual). When you are finished using the copied route in RTE1, you can erase the route from the RTE1 screen and the original stored route will remain intact in the RTE2 screen.
route. Choose In Bank - allows you to scroll through the Waypoint Bank. Align the cursor with the desired waypoint and press the EDIT key. The waypoint is automatically inserted into the active route and the unit will revert to the NAV screen, displaying bearing and distance to this waypoint. Lat. Lon. - allows you to define a coordinate and description, which is also stored at the next available waypoint location in the Waypoint Bank.
the screen. Waypoint 0, the first waypoint, is your Point of Departure, or the position you were at when you created the route. Waypoint 0 is a unique waypoint, in that the CDU internally changes the position of Waypoint 0 to your present position. However, the CDU saves and displays the original coordinates entered when you created the route. Waypoint 0 is displayed in Inverse Video, that is, white characters on a black background (when in the normal Daylight display mode; see CFG1 Lighting).
Creating a Multi-Waypoint Active Route There are four methods to create a multi-waypoint route: •• Insert By Number - allows you to type in or scroll through in numerical order using the cursor key, waypoints that you previously stored in the Waypoint Bank (see WPT later in this manual).
6 When you have found the waypoint you want, highlight the Insert this WPT softkey and press ENT. 7 You can then choose to select another waypoint using the same method, highlight Escape and press ENT to go back one level and use another method to enter waypoints, or highlight Done and press ENT to go back to the main menu. 8 Don’t forget to press the EDIT key to end your editing. Choose in Bank The following example assumes RTE1 is empty.
8 You can then choose to select another waypoint using the same method, select Escape to go back one level and use another method to enter waypoints, or select Done to go back to the main menu. 9 Don’t forget to press the EDIT key to end your editing. Insert New Waypoint The following example assumes RTE1 is empty. Follow the directions in the Erasing an Existing Route section to start with an empty route if you have waypoints in the RTE1 screen. 1 Select the RTE key until the RTE1 screen is displayed.
4 Use the cursor key to scroll through the available defined routes, which are created in the RTE 2 screen, in numerical order. 5 When you have found the route you want, highlight the Insert Fwd or the Insert Reverse softkey and press ENT. Insert Fwd enters the route from the top of the defined list into the active route. Insert Reverse enters the route from the bottom of the defined list into the active route so that you can travel down the route in the reverse direction.
Inserting Waypoints or Routes into an Existing Route 1 Press the RTE key until the RTE1 screen is displayed. 2 Scroll through the route points with the cursor key until the cursor arrow is at the waypoint you want to insert the new waypoint after. 3 Then press the EDIT key. 4 The Insert softkey is already highlighted, press ENT. 5 Highlight Insert by Numb. softkey, press ENT. 6 Enter the Wpt. # (in this example use number 1). 7 Highlight the Escape softkey then press ENT.
6 Highlight Insert Reverse softkey, press ENT. 7 Press the EDIT key to exit. Notice that you still keep the same orientation on the screen, in other words, you always read from the top of the screen to the bottom of the screen. The waypoints are rewritten in reverse order for you. ETA Setup If you choose to use this function, it is probably better to operate the unit in UTC time mode if you are going to cross one or more time zones.
In this mode, the actual SOG is compared to the required SOG to meet the specified arrival date and time. The result is given in a percentage (%) value next to the displayed SOG in the NAV screens. If the percentage is below 100, you will arrive late. If the percentage is above 100, you will arrive early. ETA Based on Speed: 1 Select a Speed Basis of either GPS SOG, which uses a long filter time (in seconds) that you define, or Constant, which uses a speed you intend to maintain (you define the speed).
7 Highlight the Done softkey and press ENT when you are finished editing the name. It is a good idea at this point to select Lock Route so that way you don’t accidentally erase the route. 8 Finally press the EDIT key to exit the edit mode. The RTE1 screen is not active until the antenna is detected. Waypoint The Waypoint Bank (WPT) is a list of waypoints that you created using various methods. The most common method is by manually entering Lat/Long coordinates.
press ENT to select it. 4 Scroll left to “Make new WPT” and press ENT to start entering L/L coordinates for waypoint #1 or if you want to modify an existing waypoint, highlight the “Edit this WPT” softkey then press ENT. a Make New WPT - Select Lat/Lon (W84), Lat/Lon Datum, or Range Bearing. Lat/Lon (W84) - allows you to enter coordinates in the WGS 84 datum. This choice takes you directly into the coordinate input screen. Go to step 5.
6 Move the cursor down and modify the waypoint number if you wish. Otherwise the CDU assigns the next available number, beginning at 1. Range & Bearing Lat/Lon This feature allows you to create a range of waypoints within a particular area. For example, you could put all of the waypoints for fishing spots near Catalina Island in the range of 500 to 530, all the waypoints for Cabo San Lucas in the range of 575 to 600, etc.
10 Then press the EDIT function key to end editing. You can press the EDIT key when you finish editing a waypoint. This is treated the same as highlighting the Done softkey and press ENT. Highlighting Done then press ENT allows you to continue editing and entering other waypoints. Waypoint Lock/Unlock Locking a waypoint forces the user to consciously unlock the waypoint before it can be modified and prevents the waypoint from being overwritten when waypoints are being input over the data port.
5 Press the EDIT key. If you simply want to modify the waypoint, Edit this WPT will be displayed on the bottom left of the screen. To Lock all Waypoints 1 Press the WPT key. 2 Scroll to the desired waypoint. 3 Press the EDIT key. 4 Highlight the More softkey and press ENT. 5 Highlight the More softkey again and press ENT. 6 Highlight the Lock all WPT softkey and press ENT. 7 Press the EDIT key. To Unlock all Waypoints 1 Press the WPT key. 2 Scroll to the desired waypoint.
5 There are three methods to remove a waypoint: Remove this WPT, Remove Unused, and Remove Range: a If you select Remove this WPT, the waypoint will immediately be removed from the Waypoint bank. b If you select Remove Unused, the CDU will delete all waypoints that are not locked or stored in a route. You will be prompted to confirm the deletion: c If you select Remove Range, the CDU will delete all unlocked waypoints that are not stored in a route between a range of waypoint numbers that you enter.
b To move a range of waypoints, enter the first and last waypoint numbers to move on the First WPT Number and Last WPT Number. Keep in mind that the CDU will sort these waypoints numerically and all waypoints between the entered numbers will be moved to the new location. 6 Enter the waypoint number where you want the first waypoint moved to in Destination WPT Number.
Saving or Restoring Memory Data Using a USB Device The MX51x is equipped with two sealed USB connectors, one in front and one in the back of the unit. They can be used to conveniently save or restore navigation data such as waypoints, routes, plot tracks and configuration settings using a USB memory stick. It is important that the USB stick be formatted first to Windows FAT 32 before using it with the MX51x. The USB formatting procedure is available in the Installation section of this manual.
5 The Change softkey is highlighted at this point, press ENT key. 6 Wait for the MX51x to recognize the USB device before proceeding. 7 Highlight “Data type” then press ENT to change to either Waypoints, Route, Plot, Config or All. Using “All” will restore everything. 8 Highlight Restore softkey then press ENT. 9 It will pop-out a dialog window asking if this is what you want to do. Answer YES (0r NO) by pressing the ENT key (or scroll to NO if you are not sure and press the ENT key).
The CDU outputs these sentences in the following format: Rnn - Routes: Waypoint identifiers, listed in order with starting waypoint first, for route number “nn”. The active route in the CDU is always route zero, but in the Rnn sentence the route number can be transmitted as either route 00 or 01. Rnn is NMEA version 1.5. Use of GPRTE is recommended to comply with NMEA version 2.1. field#: 1 2 3 4 1 1 1 4 5 6 $GPRnn,cccc,cccc,cccc,.....
Explanation / actual use: 2 & 3: Waypoint Latitude, North or South, N/S number of decimals can be set to 2, 3, 4 or 5 (default 2). 4 & 5: Waypoint longitude, East or West, E/W number of decimals can be set to 2, 3, 4 or 5 (default 2). 6: Waypoint identifier. 7: Checksum can be set on or off (default on). The WPL record can also contain the description information when Include Waypoint Names in the CFG1 NMEA, Details is selected.
3 Scroll down the menu to NMEA Out 1 (or which ever port number is required). 4 Press the EDIT key. 5 If the port is already Active (Yes), write down which NMEA sentences are set to Yes, then set all of the NMEA sentences to No. You need to do this to record just the waypoint data. If the port is not Active (No), change it to Yes. 6 Scroll down to the WPL record and change it On. 7 Highlight the Details softkey and press ENT. 8 Set Include Waypoint Names to either No or Yes.
Uploading Waypoints from a Personal Computer You can use any terminal or communications program to download or upload waypoints and routes to or from the CDU and a PC. Set the PC to: 4800 baud 8 bits 1 stop bit no parity no flow control When sending data to the CDU, it must be sent in block form, followed by (with an appended) CR (carriage return) and LF (line feed). Normal communications programs, like Windows 3.1 or 3.11 Terminal are sufficient to get the job done.
Mark / MOB This is a dual function key that either stores your present position, date and time at the next available waypoint location in the Waypoint Bank or when pressed continuously for 3 seconds, calculates a MOB range and bearing to a saved spot (See MOB section on page 58). A window pops up on the screen to confirm your key depression, and to tell you where the Mark position is being stored. You can go into the WPT menu and edit the coordinates or description later.
If you make a mistake, you can use the cursor key to position the cursor over the mistake and overwrite the error. Use the DGPS key or cursor key to insert a space in the description, if needed. Use the CFG key to select a special character, if needed. 4 To activate the GOTO waypoint, press the EDIT key. A warning is briefly displayed indicating that the active route will be replaced with the GOTO route.
Plot The PLOT1 screen displays graphic information around the boat at your present position. The boat always remains in the center of the screen. If you define some of your navigation markers in the Waypoint Bank with a symbol in the first character position, the navigation symbol will show up in relation to your planned course on the plot screen, just as it does in the NAV1 Panorama screen.
PLOT 1 - Relative to Boat The information in PLOT1 is always relative to your present position. The boat always remains in the center of the screen and the bearing and range are always from your present position to the next waypoint identified in RTE1. Customizing the Display There are a number of display options available, press the EDIT key to modify the screen to your needs. Highlight the Display Options softkey and press the ENT key.
•• Show Lat/Lon Grid - No is the default condition, which causes the coordinate grid not to be displayed. Yes causes the Lat/Lon grid to be displayed (regardless of positioning reference system selection in CFG1 Position). Note that the grid is only displayed at the 4 Nm scale or lower. •• Automatic Zoom - No is the default condition, which causes the displayed scale to be controlled by you.
Plot Screen Use Examples Station Keeping There may be a time when you want to maintain your position at a given location in open water. Some applications for this need may be: •• Staying over a dive wreck. •• Staying over a fishing hole. •• Recovering an oceanographic survey point. If you are placing and recovering crab pots along a course line, you can enter your course in the RTE1 screen, then place the marker at each crab pot in turn.
Man Over Board The Man Over Board function key shares the same key with the “Mark or Event” function key. When depressed for 3 seconds, it activates a number of automatic functions described below. Most obviously, it brings up an MOB1 (Plot) screen. This is an automatic scaling screen. The screen centers on half the distance between your present position and the MOB position.
Remote MOB The MX51x is capable of performing the MOB function from a remote contact closure input via the AUX (8-pin) cable. If the contact closure is made for 3 seconds, the input is registered as a MOB Position. Refer to the Installation section of this manual for wiring interface instructions.
AUX3 - Not Used AUX4 - Sun Almanac This almanac provides the sunrise and sunset times for a given day and location. You can enter another date or location of interest by pressing the EDIT key, and editing the appropriate date and/or place. AUX5 - Moon Phases There are no edit functions available here. Moon phases are given in approximately one week increments and include all dates for new, half, and full moon. You change the year displayed by pressing the up or down cursor keys.
MX510 AUX7 Screens MX512 AUX7 Screen This also activates several engineering screens (the same as turning Engineering Display to Yes in CFG1 Operation). Refer to Appendix B - Engineering Mode for more details. AUX 10 - Tide There are two TIDE screens, which are located under the AUX option. The AUX 10 screen displays graphic and digital information about the tide conditions at your present position.
The tide measurement units can be displayed in meters, feet, or fathoms. Tide units are controlled along with depth units in the CFG1 Depth screen. To select another port’s tide table, press the EDIT function key, and use the Change softkey to scroll down the list or the Go Back softkey to scroll up the list. While in the edit mode, you can also move the cursor down to the date and manually change it to any date you are interested in.
The display provides the required tide table document name and section (Admiralty Tide Tables, Part III) under the Help softkey when in the edit mode as an added aid to help you identify the proper reference material. Information about the Admiralty Tide Tables port lists and other publications and where they can be purchased is available from the official Admiralty Chart and Publications website at www.ukho.gov.uk.
Position There are three POS screens in the CDU. The POS functions are highly interactive with a number of CFG1 menu selections. The following CFG1 menus directly impact the POS functions: •• COG SOG - sets the filtering time for the displayed values. •• Datum - sets the reference datum for your present position. •• DGPS - sets the internal or external control for RTCM SC-104 corrections which affect your position accuracy.
User GRID User defined grids is an optional feature of the MX51x. When enabled you can set the receiver to provide Easting and Northing position data based on a local grid. The grid function is set up in the CFG1 Position screen. A special license is required to activate this special feature. POS2 - Position, Altitude, Magnetic Variation, & Time This screen is divided into three windows.
provided so that you can log the mileage for: a the current leg or day of your trip; and b the entire trip. GPS Several GPS and DGPS screens are available under the GPS function key. The GPS/ DGPS functions are highly interactive with these CFG1 menu selections: •• GPS - sets the lowest elevation at which a satellite will be tracked. •• DGPS - sets the internal beacon receiver to Auto, DGPS only, or Off. GPS1 - GPS Status Screen There are two windows in this display.
You can deselect a particular PRN# by doing the procedure below: 1 Press the EDIT key. 2 Scroll to the PRN number desired. 3 Highlight “force unhealthy” softkey, press ENT to change the value to “-”. 4 Press the EDIT key to exit. GPS3 - Visible Satellites This screen provides some basic information about the GPS receiver performance just like GPS1 and GPS2 screens.
The GPS5 screen shows the position Lat/Long, height of antenna, HDOP, number of satellites used, the satellite ID number that may cause the statistical error and its bias value. It also shows a table containing the PRN numbers of satellites in use, their residual errors and elevations. Below it is the RAIM Status indicator and time. The RAIM icon is shown on the top-right corner of the display.
GPS6 - DGPS STATUS There are several windows in this display, the left hand windows are divided into control and configuration windows. The right hand window displays all the corrections that are being received. Shown below is the GPS6 screen. MX51x GPS6 Screen Status will tell you whether the correction data is being decoded is error free or not. Normally, Status will indicate either DGPS mode Off, DGPS OK, Tracking or Searching (Automatic search mode) or No Lock (Manual tuning mode).
Once you have entered the data for several beacon stations, you can cycle between these stations by pressing the Next Station or Previous Station softkeys. These softkeys are only displayed if you have entered a name for the reference station. The window on the right side of the display indicates which satellite ID’s are receiving corrections. When the PRN number is shown in inverse video, this indicates that the receiver is using the correction in the navigation solution.
Configuration The CFG screen includes setup and control of all of the MX51x’s primary functions. There are more than 20 separate configuration items in this screen. The display is divided into two windows. The left hand window identifies the primary configuration items. The right hand window displays the current settings. Use the cursor key to select a configuration item of interest, then press the EDIT key to edit the actual settings.
Compass - External Compass Input & Magnetic Variation Table The MX51x will accept compass input using the NMEA 0183 data record of xxHDT, xxHDG, xxHDM, xxHCC, xxHCD, xxVHW, or any of the above. The “xx” refers to the Talker Identifier as specified in the NMEA 0183 standard. It will accept these data records vitually from any talker ID, and from any version (1.5 or higher) of the NMEA 0183 standard. To implement this feature, change Compass Connected to Yes.
MX575: There are two ways the MX575A DGPS compass can be connected to the MX51x, namely: •• PORT3 as source of Positioning, Heading and ROT. •• PORT1 (or 2) as source of Heading and ROT only If the MX575 is used as a positioning and heading device on NMEA Port3, set Data input port no to 3. This will automatically configure the MX575 to work at 19,200 Baud rate and the HDG output will be set to 10 Hz on power up.
Echo Sounder Connected - causes the MX51x to look for one of the appropriate NMEA 0183 data sentences when set to Yes. Data Input Port No. - Select the appropriate NMEA 0183 port that the sensor is connected to (Port 1 or 2). Ports 3 and 4 are reserved for the Smart antenna controls. Offset - Input the appropriate offset for the sensor, based on the measurement you are most interested in.
Off - sets the smart antenna to operate in GPS mode only. Max Age -sets the maximum age limit that the last received RTCM correction will be applied to the satellite range measurement in the receiver. The default setting is 600 seconds. The MX51x will accept values from 10 to 999 seconds. Due to the removal of the S/A dithering from the satellite signal, you may now use values of 600 seconds in the maximum age and still be very accurate.
Whether a unit is a slave or repeater, it will still share a common waypoint and route database as the master. Refer to Appendix C for more detailed information about the dual-control and multiple unit control setup and operation. CFG1/LAN menu must be setup before enabling the Dual-Control feature. A dual control system consists of one Master and one Slave. A Multiple Unit Control (MUC) system consists of one Master, at least one Slave (maximum of two), and up to three (if any) Repeaters.
Initial Pos - Initial Position Entry This screen is provided to help the GPS receiver in the smart antenna to get a faster first position fix. While the smart antenna is capable of computing its position without any user input, this feature can cause a position fix to occur several minutes earlier. Another time this feature is useful is when the MX51x has been moved over 300 miles from the last location it was used while in the off condition.
LAN Output (NMEA 0183 OVER IP) This screen is very similar to the NMEA Out screens. It sets the specific NMEA 0183 output record parameters. The default setting is No. When this selection is changed to Yes, you can turn on individual data records, and transmit them using the Local Area Network (LAN) connection. This feature can be used to integrate the MX 510 to an Integrated Bridge System by connecting the CDU to a PC-based IBS system using LAN (RJ45).
Log - Speed Log Input (Pulse or NMEA 0183) This screen controls the input port (NMEA-0183 or Pulse) and format of the speed log input to the MX51x. In the default condition, the speed log is not connected. NMEA 0183 speed is accepted from the xxVHW data sentence originating in any of the version 1.5, 2.0, 2.1, or 2.3 format where xx is a valid talker ID as specified in the NMEA 0183 standard. The CDU will also accept speed log pulse input, with pulses of up to 1.5 kHz.
LORAN-C Integration This feature will be available only when the optional Loran-C license is purchased and activated. The MX 51x has two selections for Loran-C integration (Raytheon and Locus). Raytheon: To implement this feature, change LORAN-C connected to Yes. Identify the appropriate input port (1 or 2) that the LORAN-C device connects to by using the Change softkey. Select the appropriate Version Number with the range from 0 to 9.
The POS 5 screen displays the (D)GPS calibrated LORAN-C position received from the GLL message from the LORAN-C receiver. The POS 6 screen displays the stand-alone (uncorrected) LORAN-C position received from the RMA message from the LORAN-C receiver. When Loran-C (Raytheon) option is enabled, the MX51x gives the option to accept EUROFIX DGPS corrections instead of the External DGPS corrections under the CFG1/ DGPS Configuration screen. Locus: To implement this feature, change LORAN-C connected to Yes.
After the LORAN-C (Locus) feature is enabled, you will have 2 new screens (POS 4, POS 5), which display your LORAN-C information. The POS 4 screen displays the geographical coordinates of the Loran-C position in the form – degrees, minutes, and hundredths of a minute. The POS 5 screen displays the Station GRI, Time Difference (TD), Warning status (CYCLE, BLINK), and Signal-to-Noise (SNR) data for different slave stations of a particular Loran-C chain being used.
Memory This screen allows the user to have the option to save and restore waypoints, routes, and system configuration using the MX51x internal flash memory. Navigation - Navigation Method & Waypoint Pass Criterion Control This screen sets the navigation mode to Rhumb Line or Great Circle, Cross-track Error limits and alarms, Waypoint Pass Criterion, and Waypoint Approach alarms. These settings have a direct effect on your route calculation and how data is displayed in the NAV and PLOT screens.
XTE Alarm: Causes an alarm to sound if your position exceeds the maximum XTE Limit defined above when Yes is selected. To disable the alarm, select No (default) with the Change softkey. WPT Pass Criterion: Sets the waypoint passed determination method. There are five methods available: Complex: This is the default setting. Passing the waypoint is determined by reaching an imaginary perpendicular line.
autopilot will accept the MX51x data again. This is provided as a safety feature so that the boat does not turn toward a new direction without your knowing of the impending change. To disable the alarm, select No (the default condition) with the Change softkey. NMEA Out 1 - NMEA 0183 Output Data Control These screens set the specific NMEA 0183 output record parameters as well as the port control. The default setting is No. When this selection is changed to Yes, you can turn on individual data records.
Most: NMEA Version - Some of the NMEA 0183 records are no longer supported by version 2.3. However, you may have an autopilot, plotter, or other older model equipment that does not support the newer version of the NMEA 0183 standard. The MX51x provides you the flexibility to interface using older versions of the NMEA standard to support these devices. Decimals In Lat/Lon - The software allows you to select from 2 to 5 decimal places in records containing position or waypoint information..
WPL - Waypoint Location Data Record: The MX51x outputs all of the waypoints in the active route. If you want to output the complete Waypoint Bank, simply highlight the Send All softkey then press ENT from the NMEA WPL screen. The WPL record, as defined by the NMEA 0183 standard, technically does not allow the output of waypoint descriptions when interfacing to other devices such as Chart Plotters.
Operation - General Setup and Control Settings This screen controls a few basic operating settings: Remember Display: When set to Yes (default), the MX51x remembers the Page Number or screen you viewed the last time you used a particular function. For example, if you normally monitor the NAV3 display and you decided to look at the PLOT1 screen, the next time you press the NAV function, the MX51x will automatically revert to the NAV3 screen immediately.
The setup is straight forward. Use the Change softkey to increment forward through the available choices. Use the Go Back softkey to increment backward through the available choices. You can also use the left and right cursor keys to accomplish these same operations. Enter text the same as you do for the waypoints and routes. Use the numeric key pad to enter the appropriate time. Don’t forget to set Message Active to Yes when you are finished editing, to enable the alarm.
Printout (n) - Printer Output Control This menu item controls the printer output sometimes required for commercial shipping. The interface is accomplished on NMEA Out 2 port for the MX510 or NMEA Out 11 port on MX512 models. The printer output is simple ASCII text designed to operate on any serial line printer, including narrow column printers. The MX51x has two print formats, namely: Full or Brief.
Here is a sample of the Brief format with an active route or MOB condition: MX510 Navigator ==================================== 21:24:00 UTC 11 Aug 1997 POS Mode : DGPS 3D POS: N 33 48.5124 Datum:W84 W 118 21.0213 COG: 152T SOG: 0.1 Kn BRG: 239T Dist: 27.4 Nm XTE:0.14L Nm RTE: RL From WPT 1234 To WPT 1357 ------------------------------------------------------------------------Sending: Causes the printer output to be turned On or Off (default).
Security The Security screen allows you to lock out the EDIT key in order to keep crew members or visitors from changing settings that you have made. Once this feature is enabled, a press of the EDIT key will require the correct password to gain access. To disable the security functions, you will be prompted to enter a 5 digit password. You will then be prompted to reenter the password. The security function is then disabled until you enter a new password through the CFG1 Security screen again.
Time Offset: Sets the local offset to UTC time. 0:00 is the default. Summer Time: Sets the local clock ahead one hour in the summer for daylight savings time when set to Yes, or to the Local Offset time when set to No. The adjusted time value is displayed in the lower window so you can verify the current time without having to leave the screen. USB - USB Mass Storage Configuration This option controls the saving and restoring of your waypoints, routes, and system configuration via an external USB device.
VGA This menu is available in the MX512 model only. It controls the VGA output display base (background) and font colors. To control the VGA output, do the following: 1 Press the EDIT key to bring up the cursor. 2 Press the ENT key to turn the VGA feature to ON. 3 Press the down arrow key to scroll down to Base Color. 4 Press the ENT key repeatedly until the color desired is shown. 5 Scroll down to Font Color. 6 Press the ENT key repeatedly until the deired color for font is shown.
Wpt & Rte Input - Uploading Waypoints into the MX51x This screen enables the input data port to receive waypoints and routes from a chart plotter, PC (VMS), or other device to the MX51x. You can receive this data through any of the user NMEA 0183 input data ports. Load the WPL sentences first, then the RTE sentences. Change Transducer Connected from No (default) to Yes and select the appropriate port.

Installation notes General The MX51x Control and Display Unit (CDU) is splashproof and can be installed both above and below deck. To flush mount, use the optional flush mount bracket. Ensure that the navigator is mounted in a dry place or where water flows off easily. Avoid places where water may accumulate for any period of time. Electronic Connections Refer to figures in Section 5 for the mechanical drawings of the display console and for the electrical interface cables.
Wire Preparation Procedure PWR/DATA Cable (6-Pairs Twisted): We recommend that the main cable insulation (black plastic) be stripped about 5 inches back to expose the color-coded leads. Below are the color and signal designation of the wires: Pin 1 --- Red ----------- +10-32 VDC Pin 2 --- Black -------- Negative GND.
Antenna Installation Antenna Location The MX series smart antennas (MX421, MX521, MX575 & MGL3) are designed for exposed installation. They should be mounted with a relative clear view of the horizon as shown in page 120 of this manual. Do not, mount the antenna on top of a very tall mast, as this may degrade the COG and SOG calculations, particularly when in DGPS mode.
External Differential Connection Differential corrections from an external beacon receiver can be connected to either the MX421-10 (GPS only) or the MX521A/MX525A D/GPS models. RTCM connections are done directly to the antenna cable; MX421 (GPS only) antenna -- Pins 7 (yellow) and 8 (white) MX521A/MX525A antenna ---- Pins 9 (purple) and 10 (grey) The MX series antennas are compatible with the standard RTCM SC-104 signal at 4800 baud.
If the external power to the unit fails for any reason, the navigator will remember if it was on or off for about 20 minutes. That is if the navigator was on when the power failed and the power comes back within 20 minutes, the navigator will turn itself on again. Otherwise, it will stay turned off until the key is pressed. Equipment Interfacing Introduction The MX510 has two user NMEA ports while the MX512 has nine.
External Alarm Output The MX51x Ext. alarm output connection is on pins 3 and 4 of the AUX (8-pin) cable. They are held open (floating) during normal operations. In an alarm condition, the external alarm pin is switched to ground potential. When an alarm condition is cleared or acknowledged, the Ext. alarm signal will return to open condition automatically (refer to table below for relay conditions).
The minimum output voltage may be as low as ±2 volt. This is not compatible with the former 4 volt input threshold and may be the cause of interface problems. If this is the case, try using an RS-232 to RS-422 convertor to interface with the MX510. This may more likely solve the problem. Otherwise third party conversion boxes may be necessary. Cables provided for the NMEA signals are shielded pairs.
NMEA Output Sentences All sentences have the identifier “GP” for Global Positioning Systems. All position data are in the user selected (displayed) datum except for GGA where the datum can be manually set to WGS84, independent of the selected (displayed) datum. RMB is transmitted only if an active route is present. Please refer to the Route section of the Operator’s Manual for details on setting up an active route.
Viewing Input Data You can view data being sent to the MX51x by other equipment or loop the output port back to an unused input port to verify if it is outputting data to other equipment. This is a great tool to use when you are first interfacing equipment. To activate the Input Data screen: Press CFG . Scroll through the menu and select Operation. Press EDIT and change Engineering Display from No to Yes. Press EDIT again to exit the edit mode.
MX51x LAN Crossover (Null) Cable Diagram The interface between the two (or more) units takes place over a high speed (100 Mbps) data link. The master unit must be connected to the smart GPS antenna unit (MX421, MX521A, MX525A, or MX575A). The master unit receives the position data then transfer it to the slave unit(s) at a one second rate (the same as the position calculation). Due to the high speed data link, there is virtually no visible position delay between the two (or more) units.
MX51x/BRIM (Backup Receiver with Integrity Monitoring) Feature The Integrity Monitoring (IM) feature allows the dual-control MX51x units to constantly compare each GPS position solutions and, if configured to do so, give an alarm and/or automatically switch to the unit with the “better” GPS solution. Both MX51x units are functional D/GPS receivers and both continuously calculate GPS solutions. The IM algorithm continuously compares the two position solutions.
Troubleshooting Guide The MX51x is virtually maintenance free. There are, however, a few important points to note. Please check your installation carefully before returning the MX510 to the dealer or factory for service. A few troubleshooting tips follow. The MX51x performs a variety of self tests during normal operation. If a function fails the self test, the navigator will display an Internal Error message every one minute.
Memory Backup Battery The internal real-time clock and memory which stores the waypoints, alarm limits, etc., is backed up by a lithium battery. The expected life time is about 3 years at 21° C, but this is based on the temperature the navigator is stored at when not in use. The higher the temperature, the shorter the life of the battery. Backup Battery Replacement Marine electronics dealers or radio supply stores will typically stock the replacement battery, Type TL-5902, 3.6 V (1/2 AA) Lithium battery.
6 Insert your USB device into the USB port of the MX510. 7 Press and hold down the NAV button on the MX510 unit and power ON the unit. Release the ‘NAV’ key after the unit is powered on.) 8 MX510 CDU will now bring up the MX510 Software Bootloader. 9 Please allow a few moments for the MX510 Software Bootloader to detect and mount your USB device. 10 After the USB device is successfully mounted, the software bootloader will copy the program to RAM.
5 Click OK after format is completed. 6 Safely remove your USB device from the PC or laptop. USB Flash Drive Hardware Compatibility List The following is a list of recommended USB flash drive brands that have been tested : -- Sandisk (256MB) -- Lexar (256MB) -- PNY (256MB) -- Memorex (256MB) USB flash drives that are not listed may not work properly with the MX51x.

Appendix B - Engineering Mode The Engineering Display, which is activated in CFG1 Operation, enables an expanded series of display screens in some of the functions. In general, these screens are used by the technician during troubleshooting or by SIMRAD engineers during testing and software debugging. This section describes what information is relevant to you, or the information we need to help you troubleshoot your MX51x.
Then, the CDU will conduct a Keylight test. You may need to dim the lights in the room or shade the keyboard so that you can see the backlights behind the function and softkeys. Observe that the keypad backlights go through their full range of illumination. Highlight OK then press ENT if it varies correctly or Fail if it doesn’t. Next, the CDU will conduct a Beeper test. Listen that the internal beeper activates for about a second. Highlight OK then press ENT if it varies correctly or Fail if it doesn’t.
4 Press the POS function key. If the position reads N 00° 00.0000, W 000° 00.0000, then the CDU was properly reset. If it does not, try the procedure again. A common source of memory corruption is when the Lithium memory back-up battery gets depleted. This will result in either a slow deterioration of memory retention or it may abruptly dump all its memory. It is recommends the battery be changed every 2 to 3 years of operation by an authorized technical dealer.
Antenna Reset Tools Special tools are available in the MX51x CDU that can be used to reset the GPS and Beacon engines in the smart antenna. Use them only in extreme cases when the GPS or beacon receiver fails or takes too long to lock-on. The “MX Ant Reset” softkey will clear the satellite almanac memory of the GPS engine and reset all settings of the antenna to factory default conditions. The “CSI Reset” softkey resets the differential beacon board.
Appendix C - Multiple Unit Control (Via LAN) Dual Control Configuration: The Dual Control mode allows you to connect one MX51x as a Master and another MX51x as a Slave unit. This allows a common data base to be shared between the two CDU control heads. This configuration also allows you to use one antenna connected to the Master unit for both CDUs. The remaining data ports, the MOB/Event input port, and the alarm output ports are still available on each unit for individual use on each CDU.

The interface among the units takes place over a high speed (100 Mbps) data link. The master unit must be connected to the antenna. The master unit receives the NMEA signals from an MX antenna and pass it along to the slave and repeater units at a one second rate. Due to the high speed data link, there is virtually no visible position delay among the units.
Blank page 154 | Appendix C - Multiple unit control
Appendix D - Demonstration Mode This enables the CDU to function as though you are under way, even though you are completely stationary. The default setting is No. When set to Yes, all three Traffic Lights will be illuminated, and a D symbol is displayed in the upper left corner of every display. Generally speaking, this feature is used by SIMRAD and dealers for show room or trade show demonstrations. However, you can use it as a training tool until you become familiar with the CDU.
Now just use the CDU as you normally would. You can output NMEA 0183 data records to other devices. Be careful, however, other instruments may interpret the data as completely valid. So, don’t run the Demonstration Mode while you are underway.
Appendix E - AIS connection for MX512 only Introduction AIS is a shipborne broadcast transponder system in which ships continually transmit their ID, position, course, speed and other data to all other nearby ships and shoreside authorities on a common VHF radio channel.
Coastal Surveillance In coastal waters, shoreside authorities may establish automated AIS stations to monitor the movement of vessels through the area. These stations may simply monitor AIS transmissions from passing ships, or may actively poll vessels via the AIS channels, requesting data such as identification, destination, ETA, type of cargo and other information.
shipping agency information, tides and currents, notices to mariners and other information from shore to ship, as well as ship-to-ship and ship-to-shore AIS reports. It is also possible for the VTS to broadcast the complete harbor picture to all ships in the area, so the masters and pilots all share the same “big picture.” The VTS center can assume control over the assignment of time slots for AIS messages to ensure optimum data exchange within the coverage area.
GPS satellite message. Thus, GPS plays a critical role in AIS, providing the universal time reference as well as positioning data for each ship. AIS data transmissions utilize a robust 9.6 kbps FM /GMSK (Gaussian Minimum Shift Keying) modulation technique, which is specified in ITU Recommendation M.1371.1. The International Telecommunications Union (ITU) has designated two dedicated frequencies for AIS. They are 161.975 MHz (marine band channel 87B) and 162.025 MHz (channel 88B).
-- manually entered) -- Rate of turn (where available) Voyage related data -- Ship’s draft -- Hazardous cargo (type) -- Destination and ETA (at master’s discretion) Safety-related messages -- As needed Dynamic information is derived from interfaces with the ship’s GPS and other sensors. Static information is programmed into the unit at commissioning. Voyage-related data is entered manually by the master through a password-protected routine.
MX512/AIS the Total Shipboard GPS/DGPS/AIS Solution There are two AIS licenses available for the MX512 CDU model, namely: -- MX512/ Basic MKD, and -- MX512/AIS Navigation The Basic MKD license provides control and display interface to the MX535A AIS transponder and other navigation sensors, while the MX512/AIS does all this and also provides complete DGPS navigation functionality.
Follow the procedure below to select the “Transponder Type” and “Static Config Update” settings: 1 Press the CFG key. 2 Scroll to the AIS Config menu. 3 Press the EDIT key (the default value will be on Nauticast). 4 If not, press the ENT key to activate the ‘Change’ softkey to toggle to Nauticast. 5 If you need to pass control to ECDIS, press the Down arrow key to highlight the “Static Config Update” line.
Note: A total of 35 lines are available under the AIS Static menu. If only 10 lines are available when you scroll down, the MX512 may not be communicating with the transponder.

Appendix F - Glossary AIS - Automatic Identification System. A shipboard broadcast transponder system in which ships continually transmit their ID, position, course, speed and other data to other nearby ships and shoreline authorities on a common VHF radio channel. ALARM Message by which the navigator signals the occurrence of an event. The alarm is indicated by an audible tone and/or a message (or icon) on the display.
CENTRAL MERIDIAN The meridian (see MERIDIAN) that passes through the center of the referenced grid (Zero longitude). CHARACTER STRING Contiguous characters (other than spaces) in a message. CHECKSUM The value sent with a binary-coded message to be checked at the receiving end to verify the integrity of the message. CLICK (KEYBOARD) The audible tone generated when a key is activated.
CURSOR A flashing rectangle superimposed on a character position in the display window, indicating that a character may be entered in that position, or that the existing character may be changed via the keyboard. DATUM The framework on which the coordinates used to define position on the Earth’s surface are based. In the navigator, a datum is defined by the following parameters: A and I/F. Size and shape of a reference ellipsoid. DX, DY, DZ.
ELEVATION ANGLE The angle made by the line-of-sight range to the satellite and the horizontal plane of the navigator antenna. Thus, the elevation angle is 90 degrees when the satellite is overhead and 0 degrees when it first appears on the horizon. Satellites whose maximum elevation angle is less than 5 degrees are not good candidates for providing an accurate position (latitude and longitude) update. ELIPSOID A spheroid whose north-south axis is shorter than the east-west axis (oblate spheroid).
GEOID The Earth’s surface with all topographical undulations removed (equipotential surface) so that all points on the surface approximate mean sea level. GEOIDAL HEIGHT Deviations of the geoid above and below the ellipsoid due to non-uniformity of the Earth’s mass. Geoidal height is positive when the deviation is outward from the central volume of the ellipsoid, and negative when it is inward.
HEALTH See SATELLITE HEALTH. IEC International Electro-technical Commission. IMO International Maritime Organization INCLINED PLANE A geometric surface that is tilted with respect to another arbitrary reference plane (for example, the Earth’s equatorial plane). INITIALIZE To enter constants into the navigator to enable it to start positioning and/or navigating accurately.
MAGNETIC DEVIATION The error introduced into the steering compass reading by nearby ferrous metal mass distorting the earth magnetic flux field surrounding the compass. MAGNETIC HEADING Direction, as sensed by the steering compass, in relation to magnetic north. MAGNETIC NORTH Direction in the plane of the observer’s horizon toward the earth’s north magnetic pole. MAGNETIC VARIATION The angle by which magnetic north varies from true north at any given point on the earth’s surface.
PARITY CONVENTION In checking message parity (refer to PARITY CHECK), the software may be designed to check either odd parity or even parity. The choice is called parity convention: either odd or even parity convention. Under odd parity convention rule, the binary-coded message has the parity bit set to make up an odd number of message bits. Under even parity convention rules, the binary-coded message has the parity bit set to make up an even number of message bits.
REFERENCE ELLIPSOID A mathematical description of the Earth’s ellipsoidal shape (see ELLIPSOID), which is the reference frame for positioning computation. REFERENCE GPS MONITOR A GPS CDU whose precise (surveyed) position is known. It compares its own GPS position solution to the surveyed position and generates correction values as a function of the position coordinate differentials. The correction values are transmitted to user GPS CDUs for use as corrections to their own GPS position solutions.
SIGNAL-TO-NOISE RATIO (S/N) Quantitative relationship between the useful and non-useful part of the received satellite signal. A high S/N indicates a good receiving condition. S/N See SIGNAL-TO-NOISE RATIO SOFTWARE Values programmed and preloaded into memory. The values represent a permanent set of instructions for running the automatic functions (computations) of the navigator.
TRUE HEADING Direction in relation to true north. True heading is compass heading corrected for MAGNETIC DEVIATION and VARIATION. The true heading used by the navigator for navigation calculations is a composite of magnetic heading input from the NMEA compass, magnetic variation as calculated by the navigator, and the values entered into the compass deviation table. TRUE NORTH Direction along the meridian of the observer to the north pole.
VTS Vessel Traffic Service WAYPOINT A point, usually along the track of the vessel or vehicle, whose position coordinates may be stored in the navigator. The point position is the basis for the heading, range, heading-to-steer, estimated time of arrival, and steering display calculations. WAYPOINT CLOSURE VELOCITY (WCV) The speed the vessel is moving in the direction of the next waypoint. WCV should be used for optimization in cases where TWD is expected to vary drastically before the waypoint is reached.
