Overview Contemporary Research presents the AV6x4, a flexible, controllable matrix switcher for routing six stereo A/V inputs to four stereo A/V outputs. Using the simplified front-panel controls, it's easy to switch VCRs, DVDs CDs, cameras and other sources to TVs, projectors, and plasma displays. Route and input to any combination of outputs, send both audio and video, or switch audio and video separately. Advanced capabilities are available from front-panel programming as well, i

RS-232 Control Protocol Overview The AV6x4 full-duplex RS-232 scheme enables a system programmer to control all routing functions as well as monitor 3 groups of unit status. All commands are sent as ASCII strings. No delays between characters or commands are required, as data is interrupt driven and buffered. There are three types of commands and responses—Crosspoint, Input Gain and Front Panel. Crosspoint commands route Input 1-6 audio and video to Outputs 1-4. Audio Gain commands

RS-232 Commands Crosspoint Commands A Crosspoint command sends inputs to outputs. The command structure is simple: > [Unit] [Crosspoint (X, A, V)] [Input (0-6)] [Output (A-D)] [Input] [Output]… More than one set of Input/Output points can follow the Crosspoint command. You don’t have to include all Input/Output Crosspoints in the string, only the Crosspoints that need to be changed. A carriage return is required at the end of each command and is assumed in all examples. Paramete

Audio Gain Commands An Audio Gain command adjusts the attenuation or gain of each Input. > [Unit] [Gain] [Input (1-6)] [Level (1-6)] [Input] [Level]… More than one set of Input/Gain pairs can follow the Gain command. You don’t have to include all Input/Gain pairs in the string, only the ones that need to be changed. A carriage return is required at the end of each command and is assumed in all examples. Parameter Character Function Gain G Gain Sets the selected input to the spe
