WebIf in doubt, measure the resistance between CAN High and CAN Low without the system powered up. The resistance should ideally be less than 120 Ohms and closer to 60 Ohms if a resistor is fitted at each end of the bus. CAN bus systems which are already active (i.e. a vehicle CAN bus system) will already have the correct amount of termination. WebThe resistance between signal lines of normally performing PT CAN BUS has to be 60 Ohm. I any of the units, who contains terminal resistor, will be disconnected to perform a test, the network resistance will be (become) 120 Ohm, in the connector of disconnected unit the terminal resistor (120 Ohm) has to be placed, for total network resistance again come …
