The CAN bus has to be terminated by 120 Ohm resistors at both ends use a cable with following
parameters:
Cable type Shielded twisted pair
Impedance 120 Ω
Propagation velocity ≥ 75% (delay ≤ 4,4 ns/m)
Wire crosscut ≥ 0,25 mm
2
Attenuation (@1MHz) ≤ 2dB/100 m
Note: Communication circuits shall be connected to communication circuits of Listed equipment.

Note: A termination resistor at the CAN is already implemented on the PCB. For connecting, close the jumper
near the appropriate CAN terminal.
For shorter distances (connection within one building)
