Introduction, cont’d In this manual, the term “video model” refers to any CrossPoint 450 Plus or MAV Plus switcher that switches video. In this manual, the term “audio model” refers to any CrossPoint 450 Plus or MAV Plus switcher that switches audio. All audio models, with the exception of the MAV Plus 128 AV RCA, input and output audio on 3.5 mm, 5-pole captive screw terminals. The MAV Plus 128 AV RCA inputs and outputs audio on RCA connectors.
Each model has an internal 100 VAC to 240 VAC, 50/60 Hz, auto switchable power supply that provides worldwide power compatibility. The CrossPoint 450 Plus 2412, 2424, 3216, and 3232 and MAV Plus 2412, 2424, 3216, and 3232 each have two, primary and redundant, power supplies.
Introduction, cont’d MAV Plus switchers There are 61 different MAV Plus models available, in a combination of matrix sizes and low resolution video formats, with or without audio or with audio only.
• MAV 3216 Plus (32 inputs by 16 outputs) SVA SV AV V A • MAV 3232 Plus (32 inputs by 32 outputs) SVA SV AV V A MAV Plus HDA and HD switchers can also route low resolution RGsB and RsGsBs video signals. HDA and HD switchers can also route multiple composite video planes or S-video and composite video. If used in this way, the various video planes cannot be broken away; the input signals on the Y, R-Y, and B-Y input BNCs must be routed to the same outputs.
Introduction, cont’d Features Video — All switchers input and output video on BNC connectors. CrossPoint 450 Plus — These switchers input and output ultra-wideband RGBHV or RGBS video. They can also switch RGsB, RsGsBs, component/ HDTV, S-video, or composite video. MAV Plus — These switchers input and output NTSC 3.58, NTSC 4.43, PAL, or SECAM video or HDTV video inputs.
Digital Sync Validation Processing (DSVP™) (CrossPoint 450 Plus switchers) — In critical environments or unmanned, remote locations, it may be vital to know that sources are active and switching. Extron’s DSVP confirms that input sources are active by scanning all sync inputs for active signals. DSVP provides instantaneous frequency feedback for composite sync or separate horizontal and vertical sync signals via the switcher’s serial ports or Ethernet port.
Introduction, cont’d Operational flexibility — Operations such as input/output selection, setting of presets, and adjustment of audio levels can be performed on the front panel or via the Ethernet or serial link. The serial links allow remote control via a PC or control system. The Ethernet link allows multiple remote links with two levels of password protection.
Power — The matrix switchers’ 100 VAC to 240 VAC, internal power supply(s) provides worldwide power compatibility. Primary and redundant power supplies — (CrossPoint 450 Plus and MAV Plus 2412, 2424, 3216, and 3232 switchers only) Includes two internal 100 VAC to 240 VAC, 50/60 Hz, auto-switchable power supplies, which provide worldwide power compatibility. The power supply circuitry is configured to automatically switch over from the primary supply to the hot redundant supply in the case of a failure.

I/O grouping I/O grouping is a matrix switcher feature that allows you to subdivide the front panel control of the matrix into four smaller functional sub-switchers and limit tie creation from the front panel only. Inputs and outputs can be assigned to one of four groups or not assigned to any group. Inputs and outputs that are assigned to a group can only be tied to other outputs and inputs within the same group when you are creating ties on the front panel.
Operation, cont’d The I/O groups can be set up on the front panel or by using serial port and Ethernet ports and either the SIS or the Windows control program (see chapter 4, “Programmer’s Guide”, and chapter 5, “Matrix Software”. Create I/O groups on the front panel as follows: I/O groups are protected when front panel lock mode 2 is selected. You can view the groups in lock mode 2, but not change them from the front panel. 1.

Operation, cont’d Reading the displayed volume This section is a detailed look at reading the output volume display on the switcher’s front panel. If you do not need to read the exact value of the volume setting, skip this section. There are 65 steps of volume attenuation, with 1 dB per step (button push), except for 0-to-1, which is 13 dB. At maximum attenuation, no input buttons are lit, 76 dB of attenuation is applied, and the audio output is effectively muted.
Audio volume adjustment settings Highest # input button lit dB of Output Highest # input button lit dB of Output 12-input 16-input 32-input attenuation volume 12-input 16-input 32-input attenuation volume switcher switcher switcher switcher switcher switcher None 1 1 Slow blink Fast blink None 1 1 1 2 Slow blink 2 2 2 Fast blink 3 2 3 Slow blink 3 4 3 Fast blink 4 3 4 Slow blink 5 5 4 Fast blink 6 4 5 Slow blink 6 7 5 Fast blink 7 5 6 6 Slow blink Fast blink 8 8 None 76 0%
Operation, cont’d When all input buttons are lit for any switcher model, the audio output is 100% of the audio input level. Another way to view the volume level is to think in terms of the attenuation that is applied to the output. Attenuation reduction is indicated by the lit or blinking input buttons: when fewer input buttons are lit, attenuation is greater (and the volume is quieter).
Example 11: Viewing and adjusting an output volume level The following steps show an example in which the audio output volume is viewed and adjusted. The steps show the front panel indications that result from your action. Audio output volume is displayed differently on different models. See the table on page 3-43.
Operation, cont’d Figure 3-69 shows the same volume (41.5%) as in figure 3-68, but displayed on a 12-input-button switcher, such as a CrossPoint 450 Plus 128 HVA.

Advanced features consist of: Creating I/O groups Setting RGB delay Setting video and audio output mutes Setting audio output volume Setting the rear panel remote port protocol and baud rate The switcher ships from the factory in Lock mode 2. Selecting Lock mode 2 or toggling between mode 2 and mode 0 If the switcher is in Lock mode 0 or mode 1, this procedure selects mode 2. If the switcher is in Lock mode 2, this procedure selects mode 0 (unlocks the switcher).
Operation, cont’d Performing a system reset from the front panel The front panel reset is identical to the Esc ZXXX SIS command (see chapter 4, “Programmer’s Guide”). A system reset clears all ties and presets, all video and audio mutes, resets all I/O grouping, sets all input audio levels to unity gain (+0 dB), and sets all output volume levels to 100% (0 dB of attenuation).
Selecting the rear panel Remote port protocol and baud rate This procedure affects the rear panel Remote port only. The front panel Configuration (RS-232) port’s variables can be changed under serial port or Ethernet control only. See the Command/Response table for IP SIS commands, in chapter 4, “Programmer’s Guide”, to configure either port under SIS control. The Remote port settings are protected when front panel lock mode 2 is selected.
Operation, cont’d The serial port settings are protected when front panel lock mode 2 is selected. You can view the settings in lock mode 2, but not change them from the front panel. If front panel lock mode 2 is selected and you try to perform step 3, the actions are ignored and the Enter, RGBHV/Video, and Audio buttons flash. 3. To change a value, press and release the button that relates to the desired value (figure 3-80).
Rear Panel Controls The rear panel has a Reset button that initiates four levels of matrix switcher resets. Press and hold the button while the switcher is running or while you apply power to the switcher for different reset levels. Performing soft system resets The CrossPoint 450 Plus and MAV Plus switchers have three soft resets available that restore various tiers of switcher settings to their default settings.
Operation, cont’d Press and hold the Reset button until the front panel RGBHV (CrossPoint 450 Plus)/Video (MAV Plus) and Audio buttons blink once (events reset), twice (system reset), or three times (absolute reset) (figure 3-82). RESET Events Reset Reset LED flashes once. Release, then immediately press and release again. 3 seconds RESET Press and hold the Reset button. RESET 1. Front panel I/O buttons flash once. I/O RGBHV AUDIO Reset LED flashes twice.
The hard reset restores the factory-installed firmware. The switcher reverts to that factory firmware the next time power is cycled off and on unless a firmware update is performed before the power cycle. 1. If necessary, turn off power to the switcher. 2. Press and hold the Reset button on the rear panel while you apply AC power to the switcher (figure 3-83). RESET Press and hold the Reset button while you apply power to the switcher.
Operation, cont’d Optimizing the Audio (Audio Switchers) Each individual input audio level can be adjusted within a range of -18 dB to +24 dB, so there are no noticeable volume differences between sources and for the best headroom and signal-to-noise ratio. Adjust the audio gain and attenuation as follows: 1. Connect audio sources to all desired inputs and connect the audio outputs to output devices such as audio players.
Configuration Worksheets Rather than trying to remember the configuration for each preset, use worksheets to record this information. Make copies of the blank worksheet on page 3-61 (32-input button and -output button switchers) and page 3-63 (16-button switchers) and use one for each preset configuration. The worksheet accommodates all of the CrossPoint 450 Plus and MAV Plus models. Cross out all unused or inactive inputs and outputs. Use different colors for video and audio.
Operation, cont’d Worksheet example 2: Daily configuration Figure 3-85 continues from worksheet example 1 by showing the video and audio ties that make up the configuration of preset 1. A solid ink line shows video ties and a dashed pencil line shows the audio ties.
Worksheet example 3: Test configuration The A/V system in our fictional organization needs to be fine tuned on a regular basis. Figure 3-86 shows a typical test configuration, with an Extron video test generator (input 12) generating a test pattern to all monitors (outputs 1, 2, 3, 4, 8, 9, 10, and 12). Sound checks are run from the CD player (input 5) to all audio systems (outputs 1, 2, 4, 5, and 8).

Programmer’s Guide, cont’d Programmer’s Guide Serial Ports The switcher has one or two serial ports that can be connected to a host device such as a computer running the HyperTerminal utility, an RS-232 capable PDA, or a control system. These ports make serial control of the switcher possible. The serial ports are: • The rear panel Remote (RS-232 or RS-422) port, a 9-pin D female connector • The front panel Configuration (RS-232) port, a 2.
Front panel Configuration port (matrix sizes up to 1616 only) This port is hardwired for RS-232 only. The optional 9-pin D to 2.5 mm mini jack TRS RS-232 cable, part #70-335-01 (figure 4-2) can be used for connection to the Configuration port. 6 feet (1.
Programmer’s Guide, cont’d Ethernet Link The rear panel Ethernet connector on the switcher can be connected to an Ethernet LAN or WAN. This connection makes SIS control of the switcher possible using a computer connected to the same LAN or WAN. Ethernet connection The Ethernet cable can be terminated as a straight-through cable or a crossover cable and must be properly terminated for your application (figure 4-2).
Host-to-Switcher Instructions The switcher accepts SIS (Simple Instruction Set) commands through the serial ports and Ethernet port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each switcher response to an SIS command ends with a carriage return and a line feed (CR/LF = ), which signals the end of the response character string. A string is one or more characters.
Programmer’s Guide, cont’d Vmtnn•x The switcher initiates the Vmt message when a video output mute is toggled on or off from the front panel. “nn” is the output number, • is a space, and “x” is the mute status: 1 = on, 0 = off. Amtnn•x The switcher initiates the Amt message when an audio output mute is toggled on or off from the front panel. “nn” is the output number, • is a space, and “x” is the mute status: 1 = on, 0 = off.

CrossPoint 450 Plus and MAV Plus Switchers 5 Chapter Five Matrix Software Matrix Switchers Control Program Special Characters Button-Label Generator
Matrix Software, cont’d Matrix Software Matrix Switchers Control Program The Windows-based Extron Matrix Switchers Control Program, which communicates with the switcher via the rear panel Remote RS-232/RS-422 port, the front panel Configuration (RS-232) port (matrix sizes up to 1616), and the LAN port, provides an easy way to set up ties and sets of ties. The program is compatible with Windows 2000 and Windows XP.
Follow the on-screen instructions. By default, the Windows installation of the Matrix Switchers Control Program creates a C:\Program Files\Extron\ Matrix_Switcher directory, and it places three icons into a group folder named “Extron Electronics\Matrix Switchers.” The three installed icons are: 4.
Matrix Software, cont’d Using the software Many items found in the Matrix Switchers Control Program are also accessible via front panel controls (see chapter 3, “Operation”) and under SIS control (see chapter 4, “Programmer’s Guide”). The Matrix Switchers Help Program provides information on settings and on how to use the control program itself. 1.

If the address is not correct: Either click in the Extron IP Address field and enter the IP address or click on the scroll down button ( ) and select from among the recently used addresses. Proceed to step 3b. If the local system administrators have not changed the value, the factoryspecified default, 192.168.254.
Matrix Software, cont’d Figure 5-6 — Sample program window (complete) 5-6 • To set up audio in follow mode (audio and video have the same tie configuration), select the Follow box at the bottom of the window. To set up audio in breakaway mode (audio and video have different tie configurations), deselect the Follow box. • To make the control program easier to use, assign a device icon to each input and output.
IP Settings/Options window The IP Settings/Options window (figure 5-7) provides a location for viewing and, if connected via either serial port or if logged on via the Ethernet port as an administrator, editing settings unique to the Ethernet interface. See appendix A, “Ethernet Connection”, for basic information about IP addresses. None of the fields on this screen can be edited while you are logged on as a user.
Matrix Software, cont’d Matrix IP Address field The Matrix IP Address field contains the IP address of the connected matrix switcher. This value is encoded in the flash memory in the switcher. Valid IP addresses consist of four 1-, 2-, or 3-digit numeric subfields separated by dots (periods). Each field can be numbered from 000 through 255. Leading zeroes, up to 3 digits total per field, are optional. Values of 256 and above are invalid. The default address is 192.168.254.
Gateway IP address field The Gateway IP Address field identifies the address of the gateway to the mail server to be used if the CrossPoint 450 Plus or MAV Plus switcher and the mail server are not on the same subnet. Valid IP addresses consist of four 1-, 2-, or 3-digit numeric subfields separated by dots (periods). Each field can be numbered from 000 through 255. Leading zeroes, up to 3 digits total per field, are optional. Values of 256 and above are invalid. Edit this field as follows: 1.
Matrix Software, cont’d Date field The Date field displays the current date in the Greenwich Mean Time zone. If necessary, adjust the date as follows: 1. Click in the Date field. A set date field appears with the date in the format (M)M/(D)D/YYYY. Leading zeroes are not used. The graphic cursor becomes a text cursor in the set date field. 2. Edit the field as desired to set the proper date. Leading zeroes are optional. 3.
Use Daylight Savings checkbox Click in the Use Daylight Savings checkbox.

CrossPoint 450 Plus and MAV Plus Switchers A Appendix A Ethernet Connection Ethernet Link Subnetting — A Primer
Ethernet Connection, cont’d LINK ACT The rear panel Ethernet connector on the CrossPoint 450 Plus or MAV Plus switcher can be connected to an Ethernet LAN or WAN. This connection makes SIS control of the switcher possible using a computer connected to the same LAN. ETHERNET Ethernet Link Ethernet connection The Ethernet cable can be terminated as a straight-through cable or a crossover cable and must be properly terminated for your application (figure A-1).
Ping to determine Extron IP address The Microsoft Ping utility is available at the DOS prompt. Ping tests the Ethernet interface between the computer and the CrossPoint 450 Plus or MAV Plus switcher. Ping can also be used to determine the actual numeric IP address from an alias and to determine the web address. Ping the switcher as follows: 1. On the Windows task bar, click on Start > Run. 2. At the Open prompt, type command. 3. Click on the OK button. 4.
Ethernet Connection, cont’d Microsoft (R) windows 2000 (TM) Version 5.0 (Build 2195) Welcome to Microsoft Telnet Client Telnet Client Build 5.00.99203.1 Escape Character is 'CTRL+]' Microsoft Telnet> Figure A-3 — Telnet screen Telnet tips It is not the intention of this manual to detail all of the operations and functionality of Telnet, however some basic level of understanding is necessary for operating the CrossPoint 450 Plus or MAV Plus switcher via Telnet.
Local echo Once connected to the CrossPoint 450 Plus or MAV Plus switcher, by default, Telnet does not display your keystrokes on the screen. SIS commands are typed in blindly and only the SIS responses are displayed on the screen. To command Telnet to show keystrokes, at the Telnet prompt, type set local_echo and then press [Enter] before you open the connection to the switcher. With local echo turned on, keystrokes and the switcher’s responses are displayed on the same line.
Ethernet Connection, cont’d Subnetting — A Primer It is not the purpose of this manual to describe TCP/IP protocol in detail. However, some understanding of TCP/IP subnetting (a subnet is a subset of a network — a set of IP devices that have portions of their IP addresses in common) is necessary in order to understand the interaction of the CrossPoint 450 Plus or MAV Plus switcher and the mail server gateway.
Determining whether devices are on the same subnet To determine the subnet, the local device’s IP address is compared to the remote device’s IP address (figure A-6). Each address’s octets are compared or not compared, depending on the value in the related subnet mask octet. • If a subnet mask octet contains the value 255, the related octets of the local device’s address and the remote device’s IP address are unmasked. Unmasked octets are compared (indicated by ? in figure A-6).
