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 allows the modules
to 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 24V Common is not referenced to earth ground, we recommend that 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.
