Appendix C Cabling Requirements for PXI-8460 Low-Speed CAN
PXI-8461 or PXI-8460 and NI-CAN for Windows 98/95 C-2 www.natinst.com
CAN_H and CAN_L are signal lines that carry the data on the CAN
network. These signals should be connected using twisted-pair cable.
The V+ and V– pins are used to supply bus power to the CAN physical
layer if external power is required for the CAN physical layer. If internal
power for the CAN physical layer is used, the V- pin serves as the reference
ground for CAN_H and CAN_L. See the next section, Power Supply
Information for the Low-Speed CAN Ports, for more information.

For port one of the PXI-8460, power is configured with jumper J5. For port
