2. Connect a twisted-pair cable to the CAN_H and CAN_L terminals.
The maximum recommended cable length between the FP-1300 and
the CAN network is 0.3 m (12 in.). CAN_H and CAN_L carry the data
on the CAN network.
3. Connect a 10–30 VDC power supply to the V+ and V– terminals.
V+ and V– supply bus power to the CAN bus on the FP-1300.
4. If you are using shielded cable, connect one end of the shield to the
Shield terminal. This connection is not required for all CAN networks.
Connecting a cable shield to the Shield terminal helps reduce noise.
5. Connect the other end of the CAN cable to a connector on the CAN
network.
