NTI VEEMUX AUDIO/VIDEO MATRIX SWITCH
7
CONTROL OPTIONS
The VEEMUX-A Audio/Video Matrix Switch has four methods of control:
•
Front Panel LCD with Keypad
•
Directly via an RS232 interface
•
Remotely via Ethernet
•
Infrared Remote (optional)
Every unit comes standard with the Front Panel LCD with Keypad, RS232, and Ethernet connection built-in. If desired, the
Infrared Remote option may be requested at the time of the order. The Infrared Remote option requires the purchase of a
separate remote control device (Infrared transmitter) as well as an Infrared receiver to be installed in the VEEMUX-A. No software
is involved (see page 36 – Infrared Control). With the RS232 or WEB Interface options, there are no external devices to be
purchased. NTI provides software commands as well as a test program to ensure the RS232 functions properly (see page 10 –
RS232 Control) and a graphic user interface for use with a RS232 or Ethernet connection.
