The sbRIO-96xx is populated with one IDC header to provide connections to a CAN bus. This connector has pins for CAN_H and CAN_L, which can connect to the CAN bus signals. The CAN port uses an TI TCAN4550 high-speed CAN transceiver that is fully compatible with the ISO 11898 standard and supports baud rates up to 1 Mb/s and up to 5 Mb/s for CAN FD.

The port has two common pins (GND) that serve as the reference ground for CAN_H and CAN_L. You can connect the CAN bus reference ground (sometimes referred to as CAN_V-) to one or both COM pins. The port also has an optional shield pin (SHLD) that can connect to a shielded CAN cable. Connecting SHLD may improve signal integrity and EMC performance.
