2.1 CAN Communication Interface
The PCIeCANFD interface card uses a DB37 connector and a DB37 to 4xDB9 transfer cable. The signal
definition of the DB9 interface pins meets the requirements of the CiA standard. Figure 2.3 shows the definition of
the DB37 signal, and Table 2.1 lists the definition of the DB9 pin signal.
As shown in Figure 2.1, the cable labels "0, 1, 2, 3" correspond to "CAN0, CAN1, CAN2, CAN3" respectively,
so that the DB9 interface is connected to the actual CAN-bus network.
