Cabling Requirements for
PXI-8461 High-Speed CAN
This appendix describes the cabling requirements for the hardware.
Cables should be constructed to meet these requirements and the
requirements of the other CAN or DeviceNet devices in the network.
Connector Pinouts
Depending on the type of PXI board you are installing, it either has DB-9
D-Sub connector(s) or Combicon-style pluggable screw terminal
connector(s).
The 9-pin D-Sub follows the pinout recommended by CiA Draft
Standard 102. Figure B-1 shows the pinout for this connector.
