USING COM PORTS
Overview
The Xpert has four RS232 COM ports (Optionally eight) that can be used for communications
devices and serial sensors (with sensor specific setup blocks). The units are configured from the
factory to p5 volts out on COM3 pin 9, this allows a Sutron Xpert Voice modem to be
connected with one serial cable, to communicate and provide power, without the need to open
the unit. Pin 9 of all ports are user configurable for Ring In (RI), +5 Vdc out, +12 Vdc out,
sw5Vdc out or sw12 Vdc out (+12Vdc is input power). Switched options allow
the unit to turn on power anytime the com port is opened and turn it off when the com port is
closed.
COM1 is a modified DCE (Female), COM2 through COMx are a DTE (Male). Com 1 has pins 1
and 9 as inputs, normal DCE would use these as outputs.
DCE ports are connected to a PC using a M/F DB-9 straight-thru cable. The DTE ports can be
wired to modems and Satlink using straight cables.
