CAN Bus Termination
In a CAN bus system, both end modules must be terminated. This is necessary to avoid
transmission errors caused by reflections in the line. For the CAN bus a shielded connector
cable must be used. The cable shielding must have a low-Ohm connection to the ground.
The line termination is provided by a 120 Ω resistor on the opposing con-
nector between PIN 3 and PIN 4.
