Issue
Cannot establish CANbus communication between MPM controllers.
Environment
MPM controllers, any version
Cause
The CANbus trunk is missing the end of line resistors on the two end MPM controllers. Each of the MPM controllers which are at the end of the CANbus trunk must have an 120 ohm resistor installed.
Resolution
Install a 120 ohm resistor at both ends of the CANbus trunk.
