Terminating Resistors

The XM Bus operates correctly when there is a terminating resistor at each

end of the XM Bus:

• Terminating resistors must be 121Ω, 1%, 1/4 W.

• When installing the XM ControlNet adapter with XM modules, the

ControlNet adapter has an internal terminating resistor. The other

terminating resistor must be installed at the opposite end of the bus.

A second terminating resistor is installed across the CAN_High and

CAN_Low terminals of the XM module at the other end of the XM

Bus. Refer to

Terminal Assignments on page 16.
