RS-485
RS-485 communications must be used when the wire run to the host PC
is greater than 50 feet or there is more than one terminal in the system.
You will require an AMX-204053 TC Converter Kit for the host PC, which
includes:
•
TC Converter
• DB25M to DB9 F serial “modem” cable
You will require the following accessories for each additional RS-485
terminal:
•
AMX-206950: Communications Cable – 10’, 6 conductor RJ-11
•
AMX-206700: Junction Box
Note that when there is only one RS-485 terminal in the system, DIP
Switch 1 must be in the ON position to enable the termination resistor.

Warning! Please note that terminal #3 (used for the RS-485 cable
Shield) is disconnected from the internal RJ-11
receptacle of the junction box. This is deliberate; the
shield connection is
NOT fed through to the MTX
Terminal.
