4.3.6 Colour Selector Colours and fills are set via the colour selector control. Rotate the page selector to change a colour. Rotating the zoom selector changes colour transparency. Transparency is very important for fill colours which are used for airspace zones, observation zones and FAI area. If a fill colour is not transparent (0%), all other map items will not be seen through it. If a fill colour is 100% only the solid border will be drawn. 4.3.
4.4 Switching off Please use one of the following recommended methods for shutting down the LX8000: Method 1 Press the button with the OFF label which is displayed in navigational modes. See Chapter 5.5 for more details. A message to confirm shutdown will be shown. Method 2 Press the button with the OFF symbol for approximately 4 seconds. The OFF message will be displayed and the instrument will shut down. When the message appears you must release the power button.
5 Operating Modes The LX8000 has seven modes or main menus. All of them are selectable by rotating the upper-right knob which is also called MODE selector. The diagram below shows the mode structure of the LX8000. • • • • • • • Airport Mode, navigation and selection airports. Way Point Mode, navigation, selection and editing way points. Task Mode, Navigation, selection and editing task. Statistics Mode shows statistical data for flight in progress or logbook. Setup mode is used to configure the LX8000.
5.1 Setup Mode In the setup menu users can configure the LX8000. Turn the bottom-right knob or press the UP/DOWN arrow on the remote stick to select the appropriate setup item. Press the SELECT button or CHECK button on the remote stick to enter a menu. A dialogue or submenu will open. The setup menu is slightly different on the rear seat device as not all options are applicable. Items which are marked with an asterisk (*) are available only in the front seat setup menu. 5.1.
MacCready uses the Polar data and MacCready setting to calculate speed to fly and climb rate. • Vario uses the last four thermals average to compute climb rate and uses this value to calculate speed to fly. • Avg.Speed & Vario uses the average ground speed over the last 5 minutes for distance and Vario statistics for climb rate. • Avg.Speed & MC uses the average ground speed over the last 5 minutes for distance and MacCready.
If a new pilot is entered, upon exiting the dialogue the message “Do you want to create new profile with this pilot?” will be asked. Answer YES if you want to quickly add a new profile. For more information about profiles see Chapter 5.1.12. 5.1.3 Vario Parameters* This option is used to set the following parameters: On this page the following parameters are set: Vario needle filter sets a time constant of the vario needle. The value can be adjusted between 0.1 and 5 s with step 1.0 s or 0.1 s.
The external switch wired to the vario unit has absolute priority and will override all other switching methods. 5.1.4 Display The display menu controls screen brightness. The LX8000 has an ambient light sensor which detects ambient light and automatically increases or reduces the brightness of the screen. If the Automatic brightness checkbox is selected, the instrument will automatically adjust brightness according to current light conditions. Minimum and Maximum brightness items control value limits.
In next step the data source must be selected. A dialogue with a list of all available files will be opened. Press the COPY button to copy the selected file to the LX8000. The LX8000 will accept the following file formats: • Waypoints file: SeeYou CUP files, DA4 files and Cambridge/Winpilot DAT files. When selecting DA4 or DAT files, way points will be converted to CUP format which is the format used for internal storage of points.
Select the required airspace and press SELECT. If a check mark is shown in front of an airspace item, this airspace file will be shown in the graphics and used for proximity calculation, when enabled. To delete airspace file select the airspace item and press the DELETE button. Delete action must be confirmed. Only user airspace files can be removed. It is also possible to edit an airspace file. Select an airspace item and press the EDIT button.

All databases are published on www.lxnav.com . 5.1.5.7 Managing Flights Select the Flights menu item and press the SELECT button. A list of all stored flights will be shown. The LX8000 is capable of storing more than 1000 hours of flight logs.
Please note that not all data from the HDR file will be loaded. Glider type and class must be changed via the Polar and Glider menu (Chapter 5.1.13) as also final glide calculations are linked to this setting. HDR files do not include information about observation zone and turn point elevation. Observation zones will be set to default values (Chapter 5.1.8) and the elevation will be defined by the digital elevation model built into the instrument. 5.1.5.
and colour via the Font style and colour item. Use the lower-left knob to modify the colour and the lower-right knob to modify the style. Terrain can be rendered in three different levels. A higher level means more details. The LX8000 is optimised to work with high terrain quality. If the value off is selected no terrain will be shown; only water bodies, roads, railways and cities. The background colour is defined by the Background item. The default background is black.
eliminate airspace which is going to be too high for the day. For example, if the forecasted cloud base is to be 1500 m, set this value to 1600 m and your screen will be much more readable. Press the DEFAULT button to reset these settings back to default. 5.1.6.3 Way Points and Airports The way point and airport look and feel is defined in this dialogue. Check the show waypoints item to enable way points and airports display in navigational pages. If this item is unchecked no way points will be displayed.
Check the Show path item if you want to see the flown path. Path length defines how much of the flown path will be shown. The maximum recommended length is 60 minutes. The path can be coloured using: • Vario path style, where red colour indicates positive vertical speed and blue colour negative vario values. • Mc path style, which is based on current MacCready settings. Red colour indicates segments of the flight where we have vertical speed higher than the current MacCready setting.
Check the Show km lines item to see lines which indicate what will be the size of the completed triangle. These lines will always be plotted in kilometres scale regardless of the Units value. 5.1.6.6 Task Use this dialogue to define how a task is drawn in task mode. Task colour defines the colour of task lines. Obs.zone colour defines colours for observation zones. Use the lower-left knob to change transparency of area. 100% means completely transparent and only the outline will be drawn.
and colour item. Use the lower-left knob to modify colour and the lower-right knob to modify style. It is possible to display the flown path of tracked aircraft. Path colour and Path width define width and colour of paths. To enable paths check the Show paths item. 5.1.7 Sounds* In the Sounds setup page audio settings for the vario unit, voice settings for the LX voice module and alarms settings for the vario unit can be modified.
5.1.7.1 Audio Settings* Basically here we can set up two types of audio; audio sound for climb mode and another for cruise mode (SC). Vario audio mode has the following options: • Linear positive: sound is interrupted with silence every few milliseconds when the needle is positive; on negative side sound is linear (not interrupted). • Linear negative: inverse function to Linear positive. • Linear: sound is linear and non-interrupted in full scale range.
5.1.7.2 Voice* Voice module is part of V5 variometer. In past the LX Voice Module used to ba an LX system bus participant and receives data and power via the bus. The voice module is 100% controlled through the LX8000 via the settings described in this menu. In the Voice settings menu volume level (loudness) of the voice module and mixing level between voice and vario sound can be adjusted. In the Messages window each item can be set separately. Only checked items will be posted to the voice module.
Each type of observation zone is defined with two angles, two radii and mean bearing (Angle12). These parameters enable the creation of any known zone geometry separately for start, turn point and finish. All tasks stored in the LX8000 will match this “global” setting except those where the zone was modified in the task edit menu (see Chapter 5.7.1). Using parameters in the zone dialogue it is possible to describe all types of observation zones. Angle12 defines the orientation of the observation zone.
• • • FAI sectors, 90° and 3 km long sector is use in start, turn point and finish. 500m and start line. The 500 m cylinder is used for turn points. A 1 km long line is used for start and finish. FAI and start line. 90° and 3 km long sector is used for turn points. A 1 km long line is used for start and finish. 5.1.9 Optimization During flight the LX8000 optimises the flown path according to OLC or FAI rules. Use this dialogue to change the way instrument performs this optimisation.
Airspace warnings are the most complex ones. An airspace warning is activated by two triggers; First warning (orange) will be given when a projected position of flight for period, which is defined in the Time item, is computed to cross an airspace zone. Second warning (red) will be raised when a projected position of flight is computed to cross airspace zone and the glider is already in the buffer zone in the vertical or horizontal directions. Buffer zones are defined in the Horz.buffer and Vert.
Altitude warnings can be dismissed for 1 minute, 5 minutes or disabled. 5.1.10.3 Flarm Warnings Flarm warnings will be raised only when a FLARM module is built into the LX8000. Using this dialogue the user can define which data will be presented by the voice module. There are three types of warnings: • Traffic warnings will be raised once a new aircraft is detected by FLARM. • Collisions will be shown every time a collision risk with an aircraft occurred.
• Weight of water ballast. If this option is used the weights of the glider and pilot must be entered. Refer to Chapters 5.1.13 and 5.1.2 for more details of how to enter glider and pilot weights. 5.1.12 Hardware* Use this menu to define hardware properties such as total energy compensation, Vario indicators layout, compass calibration, FLARM module settings, AHRS calibration, NMEA output and data which will be exchanged between the rear and front digital units.
The electronic TE compensation can be fine-tuned during flight using the following procedure. It is essential that this is only done in smooth air; it is not possible to tune the TE accurately in turbulent air. Set TE compensation to 100% and TE filter to default. Accelerate up to approximately 160 km/h (75 kts) and keep the speed stable for a few seconds. Gently reduce the speed to 80 km/h (45 kts). Observe the vario indicator during the manoeuvre. At 160 km/h the vario will indicate about –2 m/s (-4 kts).
5.1.12.2 Vario Indicator Setup* The vario indicator is always part of the vario unit. However an unlimited number of secondary vario indicators can be connected to the system using the RS485 system bus. There are three different types of vario indicators; LCD vario indicator with monochrome LCD, USB-D type of vario indicator or V5 vario indicator.
Speed to fly bar symbol is indicating which speed you have to fly according to current MacCready setting, sink rate and speed. One arrow means 10units of speed faster or slower. Up red arrows mean fly slower and down blue arrows mean fly faster. Red diamond symbol shows average vertical speed. Blue arrow symbol shows current MacCready value. Green T symbol represents last thermal average value.
Upper Numeric Display: The parameter displayed can be configured separately for Vario mode and SC mode. Following parameters can be displayed; average vertical speed, local time, flight time, task remaining time. • Lower Numeric Display: The parameter displayed can be configured separately for Vario mode and SC mode. Following parameters can be shown: Altitude (NN altitude), Distance (distance to the navigation point), Glide diff.
The labels will automatically be displayed depending on the current function. warning will be displayed when the supply voltage is below 11 volts.
Competition mode is intended only for competitions. If this mode is enabled the pilot will not be able to see any Flarm data on the LX8000 map. The competition mode status is recorded in the IGC file and can be checked during scoring. If you are flying in a competition it is sufficient to turn on Competition mode. However if you do not want other aircraft to see you, you should switch mode to Privacy ON. Reduce warnings will significantly reduce Flarm warnings.
The same applies to the Airport checkbox. The message “Airport target received” is displayed. If the Task checkbox is checked the task will be synchronised with the other device. When flying an assigned area task it is worth not having the task checkbox checked. This will allow one pilot to play with “what if” scenarios. Once a proper direction is found you can send the task to the other device using the SEND action in task mode. 5.1.12.
5.1.12.8 Engine Noise* The current engine noise level is shown as a progress bar. Use this menu to display your current engine noise. 5.1.13 Polar and Glider* Use this dialogue to enter glider polar and other glider properties. standard class glider is selected. As default polar a Polars for most modern gliders are already prepared. Press the LIST button and a dialogue with a list of all available gliders will be shown. Select the required glider using the lower-right knob and press the SELECT button.
maximum take-off weight. Empty weight is weight of the glider without pilot and ballast. The overload factor is calculated as: overload = Empty.glider.weight + Pilot.weight + Water .ballast Minimum.glider.weight Pilot weight is set in the Flight recorder menu (see Chapter 5.1.2). 5.1.14 Profiles and Pilots All LX8000 settings and navigational page look and feel are stored in a profile. Profiles can be used in different ways: • For club operation or multiple pilots sharing the same glider.

Use the lower-right knob or the up/down arrow to toggle pages. 5.2.1 GPS Status Page GPS status, altitude, flight level and height are shown on this page. Sunrise and sunset are calculated for the current position. In the upper-right corner the current FLARM status is shown.
5.2.3 Satellite Sky View Information about tracked satellites is given on this page. available a message “No satellite info” is displayed. If no satellite information is Green satellites are satellites currently being used for position determination. Three concentric circles represent satellite elevation (0, 30, 60 degrees above horizon). If a satellite is in the centre of the circles it is directly overhead. When you are experiencing bad satellite reception, check this page.
5.4 Statistics Mode The Statistics mode operates in two different ways. During flight statistical data for the current flight is shown whilst on the ground the logbook for all stored flights is displayed. 5.4.1 Logbook If a SD card or USB stick is inserted into the LX8000 the user can copy a selected flight to it. Select the desired flight using the lower-right knob and then press the appropriate button.
5.5 Airport Mode Using the lower-right knob you can scroll through the pages. There are four navigational pages available. Navigational pages can be customised using LXStyler.

See Chapter 5.1.5.2 for more details about updates.
5.6 Way Point Mode Way point mode is very similar to airport mode. In this mode the user can navigate to way points from selected files. In addition to the options in airport mode there are three additional options: Edit way point, new way point and delete way point. Navigational pages can be customised using LXStyler. The description below applies to the default navigational pages. . • • • • • • • • • • • • • • • Select is used to select a way point as the new navigational target.
5.6.1 Editing Way Points Press the EDIT button. The Edit dialogue will be open with details of the selected way point. There are two possibilities to enter a position. You can modify latitude and longitude to define a position of the point or press the DIS/BRG button to enter the position as distance and bearing to a selectable point. Press the LON/LAT button to toggle back to input of latitude and longitude. Modify other attributes at your discretion.
5.6.2 New Way Point Select this option if you want to add new a way point to the active way points file. If no way points file is selected a new way point file will be created with name default.cup. A message “Do you want to copy from airport?” is displayed first. Press YES if you would like to copy it from the Airports database. An airport select dialogue will be opened. Select the airport you wish to copy. If none is selected a blank edit dialogue is opened.
5.7 Task Mode Task navigation mode is used for task manipulation. Navigation in this page is exclusively to the selected turn point of the declared task. A task can be created only from way points stored in the active way point file. A task can be loaded from tasks stored in the active way point file. A task can also be saved to an active way point file (see Chapter 5.1.5.4 for details how to set an active way point file). A task used for navigation will also be declared in the IGC file.
When any of the six buttons are pressed functions for the buttons are shown. If the selected button is pressed once more the selected action will take place. Press the MORE>> button to see more options. If the remote stick is available the behaviour is slightly different. When the check button is pressed on the remote stick menu will appear instead of the button functions. • • • • • • • • • • • • • • • Edit action is used to edit the task.
5.7.1 Task Edit Press the EDIT button and the task edit dialogue will open. A task is created and manipulated within this dialogue. A list of task points is shown. In the upper-left corner the type and total distance is displayed. In the upper-right corner the task time is shown. Use the lower-right knob to select task points or task time control. There are numerous actions available within the task edit dialogue to make creation of tasks as easy as possible. Press the MORE>> button to see more options.

Next: orients the observation zone in direction of the outgoing leg. This is usually used for start. • Prev: orients the zone in direction of the incoming leg and is usually used for the finish. • Start: orients the sector always towards the start. If the Line box is checked the sector will become a line type of observation zone. The Radius1 parameter defines half the width of the line length. Use the lower-right knob to increase the radius by 0.
There are also several options in this menu which will help competition pilots to have a less stressful start. 5.7.4.1 Gate Time Gate time is the time when the start gate is going to open. If this value is entered the instrument will not give you any message about starting a task before the gate time is reached. A notification will be given when the gate is opened. 5.7.4.
The arrival altitude to start is not based on MacCready, the glider nor the wind settings. It is calculated based on energy difference during flying straight. This will give you a very precise estimate at what altitude you will arrive at the start. Speeding up will result in greater energy loss and the arrival altitude will decrease; slowing down to best glider ratio will decrease energy loss and the arrival altitude will increase.
5.7.7 Moving a Task Point If at least one observation zone is defined as an assigned area, it is possible to move a point within this area. Moving a point will increase or decrease the total task length. Select the MOVE action within task mode. A dialogue with the current assigned area will be shown. In the upper-right corner the remaining task distance, required task speed, remaining task time, delta time and estimated time of arrival are shown.
6 Variometer and Altimeter All signals from the pneumatic sensors (altitude, speed) are derived from high quality pressure sensors which mean that no flask is necessary. The vario signal is derived from the altitude signal. All signals are temperature and altitude compensated. Mechanical needle and colour display are displaying the vario information as well as many other parameters. The display is user configurable. The variometer can be configured to show: • Range 5, 10 and 2.5 m/s or 10, 20 and 5 kts.
will not move faster than 4 m/s (8 kts) per second. It should be noted that when set to 4 the vario indicator will move four times faster than when set to 1. Summary: The Smart Vario should not be used in isolation but in conjunction with the setting of the time constant filter. When the Smart Vario is activated the time constant filter may need further adjustment to provide optimum indications.

7 Flying with the LX8000 To get the best out of the LX8000 it is important that some preparation is done prior to takeoff. Trying to configure the instrument or set a task while flying is very hazardous especially in a competition. At the least, it could spoil your whole day! Pre-flight preparation will ensure that the flight will be both safe and enjoyable. 7.1 On the Ground 7.1.1 Power on Procedure Press the power-on button.
7.1.3 Set Elevation and QNH This setting is crucial for final glide calculation: therefore pay careful attention to it. The instrument will offer elevation from the terrain database based on current latitude and longitude. Elevation will mostly be within few meters from the current elevation. Use the lower-right knob to fine-tune the elevation. If the elevation is unknown and the QNH pressure is known you should NOT press button QNH.
7.1.5 Preparing a Task While it is advisable to prepare the task properly before taking off and thus avoid mistakes made in a haste, all the following actions, preparing, editing, loading and saving, can be done while in the air. But then, the task cannot be declared in the air. Compared to the LX7007 there is no option to declare a task. There is only one task. This task will be automatically declared in the IGC file on take-off.
Usually a task sheet with observation zone definitions matching the LX8000 observation zone definition will be given. An example of a task sheet is shown on the previous page. However when an assigned area is defined only with two radials and two radii some calculation must be accomplished. Let us assume an assigned area defined as: Radial1=30°, Radial2=70°, Min.radius=50 km and Max.radius=200 km To convert this description the following calculation must be performed: • Direction set to FIXED.
There is no need to press START inside the start observation zone. You may press it any time after leaving the start observation zone or crossing the start line. The LX8000 will always take the correct time as start time. If for some reason you miss the start message you may always start the task by pressing the START button. Go to task mode and press any button. In the top row the START button is shown. Press this button and navigation will be advanced to the next turn point.
7.2.4 Entering Assigned Area Most probably when entering an assigned area auto advance is going to be turned off. The message “Inside zone” will be shown and buttons CLOSE and NEXT will appear in the lower row. Pressing the CLOSE button will dismiss the inside zone message. The task will be auto advanced to the next point when leaving the assigned area. If you want to auto advance to the next turn point earlier you may always press the NEXT button in task mode (see 7.2.3).
7.2.6 Task Finish On entering the finish zone the task stops automatically and a message will be displayed. If you want to fly a new task without landing, load the new task and press the RESTART button. The Navigate to nearest point option is very useful and actually a must if a finish cylinder is used with significantly large radius. Enabling this option will calculate the final glide to the edge of the cylinder rather than to the centre of the cylinder. 7.
8 Installation 8.1 V5 and V9 vario The LX8000 digital unit is installed in an aperture 93.5 mm wide and 81.5 mm high. The V5 vario unit and any additional vario indicators each require a standard 57 mm cut-out. Three pressure connectors are fitted to the back of the V5 vario unit. A label shows their functions. V9 vario has same functionality than V5, the only difference is, that has built in inertial platform (AHRS) • Pstatic means static pressure connector.
If the Ptotal and Static are connected the wrong way around there will be no integrator reading (average climb) during the flight. The LX8000 digital unit is connected to 12 Volt power via the 15-pin SUB-D connector. The LX8000 digital unit, V5 vario unit and other vario indicators are connected via the RS485 bus and the connectors are labelled with “RS485” at each end. Please ensure that both units are connected correctly before the first power on.
8.2 Installing the LX8000 Prepare the cut-out in the instrument panel according to the drilling template. For best viewing angle consider installing the LX8000 into position which will meet requirements shown on picture below. Position the LX8000 digital unit in the cut-out in the instrument panel. Tighten the LX8000 digital unit with attached 2.5 mm screws. When installing the LX8000 it is not necessary to remove the rotary knobs.
8.3 Installing the LX8080 Prepare the cut-out in the instrument panel according to the drilling template. Remove the press-in covers from the four main rotary switches on the LX8080. While holding the knobs, slacken the screws with a screwdriver. Now the knobs can be removed (never use power to remove the knobs, you can damage rotary switches). Remove the four M6 screws. Position the LX8080 in the cut-out in the instrument panel. Tighten the LX8080.
8.4 Installation of Options All options except AHRS (LX8000D, LX8080D, Remote Control, Compass Module & secondary vario indicators) are prepared to be connected to the RS485 system bus by use of RS485 splitting units. Installation of any option is plug-and-play and therefore requires only mechanical installation work. The LX8000 digital unit also powers all devices connected to the bus.

9 Firmware Update Firmware updates of the LX8000 can be easily carried out using the SD Card. Please visit our webpage www.lxnav.com and send us a request for the firmware update. You can also subscribe to a newsletter to receive news about the LX8000 automatically. 9.1 Updating LX8000 firmware We will send you an update file and update code. The update code is a string six letters long and the update file has the .lx8000 extension.
The LX8000 will automatically search for an update file. If more than one update file is found a selection dialogue will appear. Select appropriate update file and wait until update will finish.
10 Options 10.1 Flarm Before using Flarm it is highly recommended to read the Flarm user manual which can be downloaded from www.flarm.com. Respect all limitations listed in this document. Flarm is a collision avoidance system developed by Flarm Technologies from Switzerland. The Flarm module consists of following main parts: GPS receiver (common to both the LX8000 and Flarm), microcontroller unit, radio transceiver pressure altimeter and an optional external indicator.
To change the mode of operation, press the MODE button for approximately 2 seconds. If the radial LEDs run from top to bottom this means change over to nearest mode and vice versa. After any power off followed by power on the mode active before switching off will remain. 10.1.1.1 Obstacles Flarm unit is capable of storing co-ordinates of obstacles which could cause a collision during flight. This data is available on www.flarm.com (see Chapter 10.1.4).
10.1.2 Installation The position of the radio communication antenna is extremely important as a bad installation will reduce the system range dramatically. It is highly recommended to install the antenna on the top of the instrument panel with a suitable aluminium round plate having a diameter of about 12 cm used as a back plane and an approximately 10 cm long rubber antenna used as the radiator. The metal plate may be mounted outside or inside of the instrument panel.

Check functionality of mode key; each short press will activate audio for a short time.
In the Files and Transfer menu select the Update Databases menu item. Select the FlarmNet file and wait until the update completes. 10.2 10.3 ADSB-Receiver (TRX-1090) From firmware version 2.3, it is possible to connect to LX8000F an ADSB-receiver TRX-1090 from Garrecht Avionics (www.garrecht.com). TRX-1090 can only be connected to LX8000 with integrated Flarm option. The TRX-1090 has been developed to include the very popular FLARM collision avoidance system, which is installed in more than 13.

Run the TRX-Tool program and connect the TRX-1090 to PC using a USB cable.
Select Port2 tab and change Baudrate to 19200bps. The LX8000 and TRX-1090 are now ready for operation. On the info page you should see the TX sign and number of received objects.
10.4 Rear Seat Device (LX8000D or LX8080D) In two-seat gliders it is possible to install the LX8000D rear seat device. The LX8000D looks almost identical to the LX8000. However inside the device there is no GPS or Flarm module. The rear seat device must be connected only to the LX8000 via the RS485 bus system. Power is available from the bus hence no external power is needed. The device can be switched on only when the LX8000 is powered on.
other device. Please note that it is not necessary to have this way point in your databases as the complete way point information is sent. If Waypoint is not checked it is still possible to send a target to other device using the SEND action in way point mode. The same applies to the Airport checkbox. The message “Airport target received” is displayed. If the Task checkbox is checked the task will be synchronised with the other device. When flying an assigned area task it is worth having Task unchecked.
10.5 AHRS The LX AHRS system is designed for VFR use only. These instruments are not intended for use in type certificated aircraft. LXNAV makes no claim as to the suitability of its products in connection with FAR 91.205. 10.5.1 Installation AHRS shall be installed as close as possible to aircraft center of gravity. It should be leveled with wings and fuselage as much as possible. Take care of flying direction label on the top of AHRS box.
10.6 Compass Module Power supply Sensor The compass module is an electronic compass device (magnetic field sensor) which was developed for the LX8000. The LX8000 recognises the compass module automatically when it is plugged into the RS485 bus. The only configuration settings needed are related to the compensation procedure. An indication that the compass module is connected is the appearance of raw data readings in the compass calibration page. The heading indication is by default true.
Wind True airspeed and true heading Ground speed and ground track 10.6.1 Installation of the Compass Module The device consists of two parts: a compass sensor and an electronic device. Pay attention to the flight direction arrow and install the compass unit horizontally. All connections are plug-and-play so no mistake is possible. A RS485 splitting unit to extend the RS485 bus is included.
10.6.3 Adjusting the Compass Module The compensation of the compass is carried out in the setup/hardware/compass screen: 1. Orient the glider to face north. The N label will be automatically highlighted. 2. Stabilise the reading and press SET to save the correction for this direction. 3. Rotate the glider 45° to the right. The highlight on the label will move to NE. 4. Stabilise the reading and press SET to save the correction for this direction. 5. Repeat procedure for the remaining directions.
At the end press the OK button to save the calibration data or press CANCEL to cancel the changes in which case the previous settings will remain. Switch the unit OFF by using the OFF button to store the calibration data properly. The calibration data will remain until next calibration procedure. 10.6.4 Final Check Go back to the compass calibration page and check again the corrected data for all 8 directions. The error should now be less than 1° – 2° (better to have 1° ).
Do not forget to set the speed command input setting to TASTER (see Chapter 5.1.12.1). The original stick grip should be removed and replaced with the new one. On the top of the new grip there are 9 push buttons. An additional button positioned on the front side is for climb/cruise change over. Both the PTT and climb/cruise buttons are wired separately. All remaining buttons are connected to the built-in microcontroller and only four wires should be connected to the RS485 system bus.
