CAN Network Configuration
The following diagram describes the basic network requirements. Four separate CAN networks are represented. The
network channel assignment for each device is not reconfigurable by the end user. All CAN channels in the VCU200
are internally terminated. The VCU must always be located at the physical end of a bus. All busses must be
terminated with a 120 ohm resistor at the physical end. CAN network wiring should be accomplished by a skilled
harness builder familiar with vehicle networking.
