Features & Applications

The VEEMUX® SM-nXm-AV-LCD audio/video matrix switch routes audio and video input from many computers to multiple displays (projectors, monitors, etc.) and speakers. This switch can drive standard VGA cables, thus eliminating the need for external interfaces and coax cable connections via BNC connectors.

Signals from a range of input sources can be distributed to various output devices. A single computer video output can be routed to one or more monitors. Each video output is buffered from each input, ensuring signal integrity throughout the system. When switching ports, the audio automatically mutes until the video has been synchronized. The audio can also be muted on command.
  • Each output provides one video signal and one stereo audio signal.
  • Each input can be independently connected to any or all outputs.
  • Video bandwidth is 200 MHz or greater.
  • Supports 1900x1200 video resolution at a refresh rate of 85 Hz.

The VEEMUX switch is the ideal solution for any application where information from many computers is being presented, such as:
  • Classrooms.
  • Boardrooms.
  • Trade shows.
  • Conference and entertainment facilities.
  • Courtrooms.
  • Command centers.
  • Control rooms.

Control Methods

RS232 Control
  • Configuration and control can be done through the serial port.
  • Baud rate: 1200 through 9600.
  • Address up to 15 units with one serial port.
  • Changes multiple input-to-output connections quickly and efficiently.
    Commands
    • RS - causes switch to reset so that IN1 connects to OUT1, IN2 connects to OUT2.
    • CS - causes one INx/OUTx connection to occur.
    • CA - causes all inputs to connect to specified output.
    • RO - reads what input is connected to specified output.
    • RU - reads size of matrix, reports number of inputs and number of outputs on specified switch.
Front Panel Interface
  • Configuration and control can be done using the front panel buttons.
  • Keypad allows selection of the input source to be routed to the desired outputs.
