Cabling Requirements

This appendix describes the cabling requirements for CAN interfaces.
Cables should be constructed to meet these requirements, as well as the
requirements of the other CAN or DeviceNet devices in the network.

Connector Pinouts

Depending on the type of CAN interface you are installing, the CAN
hardware either has DB-9 D-Sub connectors(s), or Combicon-style
pluggable screw terminal connector(s).
The 9-pin D-Sub follows the pinout recommended by CiA DS 102.
FigureB-1 shows the pinout for this connector.
