VEEMUX® SM-8X8-AV-LCD (Front & Back)

RoHS Compliant Audio/Video Matrix Switch

Designed and Manufactured in the U.S.A.

Features & Applications

The 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.
  • Switch VGA video directly.
  • 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.
  • Crestron® compatible.

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.

The SM-nXm-15V-LCD Video Matrix Switch allows you to connect multiple video sources (computers) to multiple destinations (projectors, monitors, etc.)

Control Methods

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.
  • LED Matrix Display visually shows which inputs are connected to which outputs. (Available on the 8x8, 16x8, 16x12, 16x16, 32x8 and 32x16 video matrix switches.)

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.


    • CC - save connection configuration.
    • RC - recall connection configuration.
    • RV - read switch type and version.
    • 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.
    • EA - set the IP address.
    • EM - set the IP mask.
    • EG - set the default gateway.
    • ET - set the webserver timeout.
    • GO - read the input connected to specified output (Not GUI compatible).
    • GM - read input connected to all outputs (Not GUI compatible).
    • SS - enables/disables port change auto status (Not GUI compatible).
Download Firmware


  • Female RJ45 connector.
  • 10/100 BaseT Ethernet interface.
  • Supported protocol: HTTP, HTTPS, Telnet.
  • Configuration and control can be done over the Internet via Web Server or Telnet.

    Web Server

    • Password (optional SSL encryption) and Administrator configurable timeout to ensure security.
    • Up to 25 users can be logged into the web page at one time.
    • Users and administrators can access the following pages:
      • Switch page - connect any input to any output, save and recall up to 10 connection configurations, force compensation on all ports. Ports can be listed in order by port name or port number.
      • Change Password page - administrator and users can change their password (passwords are between 5 and 16 characters long inclusive).
      • Help page - review documentation on the usage of the web interface.
      • Update Webserver page - restart the webserver to resynchronize all settings with the Veemux proper.
