CAN bus termination resistor

When installing the TU501-4 on a J1939 CAN-bus, it is very important to determine if the

installation is on a “private” CAN-bus directly to the CAN controller, or if the TU501-4 is to be

installed as a stub on a CAN-bus with multiple CAN devices already attached.

The 120-ohm termination resister is a permanently installed resistor, so make sure to use and

select the correct TU501-4 CAN-bus version.

With 120-ohm bus termination (directly connected)

Without bus termination (stub connected)

NB!

When the unit is stub connected, the wire length must be minimized to avoid CAN-bus noise and

error ratio.
