ProSwitch Series Standard Routing B = Both Video and Audio V = Video Only A = Audio Only xx = Output yy = Input (If yy=00 then the output will be turned off) Examples: Bxxyy(Enter) xx=Output, yy=Input B0208(Enter) Audio and Video from Input 8 are routed to Output 2. V0106(Enter) Video from Input 06 is routed to Output 01 A15(Enter) Audio from Input 5 is routed to Output 14 To turn an output off, route from Input 00 B20(Enter) turns output #2 off. System Status D = Crosspoint Map General ProSwitch Serial Communications Requirements: 1:1 9-pin Serial (DB9) 9600 Baud 8-bit, No Parity, One or Two Stop Bits No Handshaking is required Pin 2 = Transmit Pin 3 = Receive Pin 5 = Ground

ProSwitch Series vertical interval routing switchers are high-performance audio/video units in thin profile 3RU rackmount chassis. They are configured for 16, 12, 8, or 4 sources to 2 destinations. ProSwitch routers are active switchers that accept and route almost any 1 volt NTSC/PAL, RGB, RGBS, RGBHV video source including off-the-air and non-timebase corrected signals.

ProSwitch accepts and routes mono or stereo unbalanced audio up to 2 volts p-p. Video and audio sources can be routed independently; they need not have the same destinations.

Easy manual operation from front panel push-buttons or routing commands can be sent from a computer via RS232 interface.

…. Also available in 5-channel version for RGBHV and VGA routing.
