User Manual
Balanced transmission is adopted for the CANFD bus .According to ISO11898-2: In the high-speed CANFD,
a 120 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 CANFD network topology.
The device has a built-in 120 ohm terminal resistance, which can be connected or disconnected through the
network configuration tool in ZCANPRO. For operation details, see chapter 5.5.2.
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. CANFD-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 or M12 terminal
(parallel connection, PHY is one channel), which realizes the communication between the device and the PC.
The interface is 100/1000M specification. Table 4.9 lists the interface diagram and signal definition.

specification. The physical form of the interface is the OPEN terminal, which realizes vehicle Ethernet
communication. This interface meets the 10/100M specification. Table 4.10, Table 4.11, and Figure 4.3 show the

5.5 Basic Device Configurations
When the device is used for the first time, configure the channel parameters, network parameters and
CAN(FD)-to-Ethernet parameters as required.
5.5.1 Configuring Network Parameters
When the CANFDNET device uses the "forwarding Ethernet" function, the device and the PC must be on the
same network segment, which ensures normal TCP/UDP connections. Modify the "Universal Ethernet"
configuration items as needed.
Figure 5.5 "Universal Ethernet" configuration item
1. DHCP enabling: Determine whether to enable DHCP to automatically obtain an IP address as required.
After enabling DHCP to obtain an IP address automatically, only a DHCP server device on the network
can successfully obtain an IP address and other related information.
2. IP: Configure the IP address of the device.
3. Subnet mask: Specify the subnet for the device IP address.
4. Gateway: gateway address of the device.

5.5.2 Configuring CAN (FD) Channel Parameters
The CANFDNET device has four CAN (FD) channels, each of which needs to be configured independently.
Modify the "CANx Configuration" configuration item as needed.
Figure 5.6 CAN channel configuration interface
1. Select the controller type: protocol standard for the channel device channel to access the bus.
2. Select work mode: normal mode and listen-only mode; when the channel is working in listen-only mode,
the controller will not send data (including the answer bit) to the bus.
3. Select the baud rate: when the channel works in CAN mode, you only need to configure the "arbitration
domain baud rate", and select the baud rate as needed; when the channel works in CANFD mode, the
"data domain baud rate" needs to be configured separately; when none of the options in the baud rate
list meets the requirements, you can use a custom baud rate. After calculating the baud rate parameters
in the baud rate calculator, copy the result to the "custom baud rate" configuration item.
4. Select terminal resistance enable: Determine whether to enable terminal resistance based on the
impedance matching on the bus.After the terminal resistance is enabled, a 120 ohm resistor will be
connected in parallel on the bus; after the terminal resistance is connected, the impedance on the bus
will be changed. If you do not know whether access is required, you are advised not to enable it.
5.5.3 Configuring CAN(FD)-to-Ethernet Parameters
The CANFDNET device supports 16-channel Ethernet forwarding configuration. Click the "CAN(FD) to
Ethernet" option. The "CAN(FD) to Ethernet" configuration interface appears.

2. Local port: Set the local port of the device. When it is set to 0, it will be assigned by the system by
default.
3. Destination address: In TCP server mode, you do not need to configure the destination address; in other
modes, the destination address is the address of the remote TCP server or UDP.
4. Destination port: In TCP server mode, you do not need to configure the destination port; in other modes,
the destination address is the port number of the remote TCP server or UDP monitoring.
5. Enable forwarding configuration: After configuring the parameters, select the leftmost check box of the
current configuration item.
5.5.4 Downloading Configurations
After modifying the configuration parameters, enter the password (default: 88888) in the "Current Password"
option box of the configuration item "Password Operation", as shown in Figure 5.9. Click the "Submit Changes"
button at the top of the configuration parameter interface to download the configuration to the device.After the
configuration is modified successfully, the "Modified successfully" message appears, as shown in Figure 5.10.
