Terminal resistors
The first and last node of a DeviceNet network must be
terminated by means of a 120
O
bus termination resistor.
This device is interconnected between the CAN_H and
CAN_L terminals.

EMC-conformant wiring of
the network
Electromagnetic interference may lead to unwanted effects
on the communications fieldbus, which can be significantly
reduced by using the cable described above, a shielded RJ45
connector and by terminating the screen.
The two figures below show the correct termination of the
shielding.
