NTI VEEMUX AUDIO/VIDEO MATRIX SWITCH VIA CAT5
This function is particularly useful to determine if a lack of sound from speakers is due to failed speakers, or lack of audio signal through the VEEMUX. If no signal is seen in this display, check all connections between the audio source, the XTENDEX, and the respective Input port on the VEEMUX.
Pressing <Esc> again will return to the connections display.
RS232 Interface
A user may control the VEEMUX using an RS232 interface by connecting a PC to the 9 pin DIN male connector on the VEEMUX labeled "RS232". Using a program such as HyperTerminal or the Matrix Switcher's Control Program (page 15), the VEEMUX can be setup and controlled.
When using HyperTerminal (or a similar program), configured at the same baud rate as in the VEEMUX (default is 9,600), 8 bits, no parity, no flow control, the VEEMUX can be controlled by sending the commands in the following chart, where:
SW = the Switch Serial Address <CR> = the Carriage Return character IP = the input port
OP = the output port ip = the IP address

If the first field is not a known command (as listed above) or SW field is different from the serial address programmed in the switch memory, the command will be ignored. If the SW field corresponds to the serial address, but the syntax is wrong after this field, the switch will answer with ?<CR>.
