PC Serial Port Connection
The XM-320 includes a serial port connection that allows you to connect a PC
to it and configure the module’s parameters. There are two methods of
connecting an external device to the module’s serial port.
• Terminal Base Unit - There are three terminals on the terminal base
unit you can use for the serial port connection. They are TxD, RxD, and
RTN (terminals 7, 8, and 9, respectively). If these three terminals are
wired to a DB-9 female connector, then a standard RS-232 serial cable
with 9-pin (DB-9) connectors can be used to connect the module to a
PC (no null modem is required).
