Chapter 2 Installing the XM Dynamic Measurement Module
Connect the DeviceNet cable to the terminal base unit as shown.
The device is shipped from the factory with the XM Bus node address set to
63. The XM Bus node address is set using the DIP switches that are located on
the top of the module.
See Set the Node Address on page 50 .
When connecting the XM network from one rail of XM modules to another
rail of XM modules, consider the following:
• CAN_High, CAN_Low, and XM Bus Common must be connected.
• The XM network must be terminated on either end with a 121 ohm, 1%
1/4 W terminating resistor. Note that the 1440-ACNR has an internal
terminating resistor.
See Figure 2.1 on page 19 .
Connect To Terminal
White Wire CAN_High 27
Bare Wire Shield 28
Blue Wire CAN_Low 29
Black Wire XM Bus Common 30
ATTENTION
You must ground the shield at only one location. Connecting the
shield to terminal 28 will ground the shield at the XM module. If
you intend to terminate the shield elsewhere, do not connect
the shield to terminal 28.
IMPORTANT
If the XM module is the first or last device connected to the
DeviceNet network, be sure to add a terminating resistor (121
ohms, 1%, 1/4W resistor) across the CAN High and CAN Low
wires.
See Terminating Resistors on page 23.
IMPORTANT
The baud rate for the Dynamic Measurement module is set by
way of “baud detection” (Autobaud) at power-up.
