Serial Port Connection
The XM-124 module includes a serial port connection, which lets you connect a
personal computer and configure the module’s parameters via the Serial
Configuration software utility.
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
that 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
personal computer (no null modem is required). The DB-9 connector
must be wired to the terminal block as follows.
• Mini-connector - The mini-connector is on the top of the module, as
shown below.
Mini-connector
A special cable (catalog number1440-SCDB9FXM2) is required for this
connection.
