• Mini-connector - The mini-connector is on the top of the module, as
shown below.
Figure 33 - Mini-connector
A special cable (catalog number 1440-SCDB9FXM2) is required for this
connection. The connector that inserts into the personal computer is a
DB-9 female connector, and the connector that inserts into the module is a
USB Mini-B male connector. The default communication rate is
19.2 Kbps.
DeviceNet Connection
The XM-124 module includes a DeviceNet connection that lets the modules
communicate with a programmable logic controller (PLC), distributed control
system (DCS), or another XM module.
The DeviceNet network is an open, global, industry-standard communication
network designed to provide an interface through a single cable from a
programmable controller to a smart device such as the XM-124 module. As
multiple XM modules are interconnected, the DeviceNet network also serves as
the communication bus and protocol that efficiently transfers data between the
XM modules.

WARNING: If you connect or disconnect the serial cable with power applied to
the module or the serial device on the other end of the cable, an electrical arc
can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
IMPORTANT If 24 V Common is not referenced to earth ground, we recommend you use an
RS-232 isolator, such as Phoenix PSM-ME-RS232/RS232-P (catalog number
1440-ISO-232-24), to protect both the XM module and the computer.
WARNING: The Serial port is intended for temporary local programming
purposes only and not intended for permanent connection. If you connect or
disconnect the serial cable with power applied to this module or the serial
device on the other end of the cable, an electrical arc can occur. This could
cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
