ohm terminal resistor needs to be connected to the network terminal node to eliminate signal reflection on the bus
and avoid signal distortion. Figure 4.2 shows the high-speed CAN network topology.
The device has a built-in 120 ohm terminal resistance, which can be configured to turn on or off by using the
CANFDNET configuration tool.
Note: The bus communication distance and communication rate are related to the field application and can
be designed according to the actual application and related standards. The CAN-Bus cable can be ordinary
twisted pair, shielded twisted pair or standard bus communication cable. In long-distance communication, the
terminal resistance value needs to be selected according to the communication distance, cable impedance and
number of nodes.
4.6 Ethernet Interface
The device provides one Ethernet interface. The physical form of the interface is RJ45, which realizes the
communication between the device and the PC. Table 4.8 lists the interface definition.
