Serial Control using AMX NetLinx® Controller

Control a VEEMUX Audio/Video Matrix Switch using an AMX NI-2100 NetLinx® Controller with a terminal emulator such as HyperTerminal. Use a Null Modem cable to connect the PC COM port to the AMX Program port. For connecting the AMX RS-232 port to the VEEMUX, use a straight thru, DB-9 Male to DB-9 Female cable. For some NTI products, a DB-9 to RJ-45 adapter may be required, refer to the product's User Manual for more information.
