6.2.2 Cabling
To connect CAN devices with just one CAN connector per net use a short stub (< 0.3 m) and a
T-connector (available as accessory). If this devices are located at the end of the CAN network, the
CAN terminator “CAN-Termination-DSUB9” can be used.

6.2.3 Termination
A termination resistor has to be connected at both ends of the CAN bus.
If an integrated CAN termination resistor which is equipped at the CAN interface at the end
of the bus is connected, this one has to be used for termination instead of an external CAN
termination plug.
9-pin DSUB-termination connectors with integrated termination resistor and male and
female contacts are available from esd (order no. C.1303.01).
DSUB termination connectors with male contacts (order no. C.1302.01) or female contacts
(order no. C.1301.01) and additional functional earth contact are available, if CAN
termination and grounding of CAN_GND is required.
