Cabling Requirements

Connector Pinouts

© National Instruments Corporation
This appendix describes the cabling requirements for the hardware.
Cables should be constructed to meet these requirements as well as the
requirements of DeviceNet. DeviceNet cabling requirements can be found
in the DeviceNet Specification.
The PCI-CAN, PXI-8461, and the PCMCIA-CAN bus-powered cable each
have a Combicon-style pluggable screw terminal connector. The
PCMCIA-CAN bus-powered cable also has a DB-9 D-SUB connector.
The 5-pin Combicon-style pluggable screw terminal follows the pinout
required by the DeviceNet Specification. Figure B-1 shows the pinout for
this connector.

CAN_H and CAN_L are signal lines that carry the data on the DeviceNet
network. These signals should be connected using twisted-pair cable.
The V+ and V– signals supply power to the DeviceNet physical layer. Refer
to the Power Supply Information for the DeviceNet Ports
information.
