2.8 System Connections
When the PCIeCANFD interface card is connected to the CAN-bus bus, you need only to connect CAN_L to
CAN_L and CAN_H to CAN_H signals. The CAN-bus network adopts a linear topology, and the two terminals of
the bus need to be installed with a 120 ohm terminal resistor; if the number of nodes is greater than 2, the 120
ohm terminal resistor is not required for the intermediate nodes. For branch connections, the length should not
exceed 3 m. Figure 2.2 shows the CAN-bus bus connection.

In the CAN-bus network, shielded cables are often used for interconnection, so as to enhance the
anti-interference ability. However, there are many types of shielded cables and field wiring is complicated.
