and a flexible data field with a baud rate of up to 5 Mbps.
The PCIeCANFD-400U CAN(FD) interface card is a PCIe to 4-channel CAN(FD) communication interface
card compatible with PCI Express r1.0a specification developed by Guangzhou ZLG Electronics. The
PCIeCANFD-400U interface card provides PCI Express x1 multi-function device peripheral controller interface,
which enables the computer to be easily connected to the CAN/CAN(FD) bus network to monitor multiple bus
networks in real time. It is easy to install and simple to use.
The PCIeCANFD-400U CAN(FD) interface card provides four completely independent isolated CAN (FD)
channels, conforming to CAN FD ISO 11898-1:2015 specification (compatible with CAN 2.0A/B standard). It
supports a transmission rate of up to 5 Mbps, which enables flexible and convenient applications. To improve
system reliability, the PCIeCANFD-400U interface card adopts 2,500 V DC electrically isolated CAN (FD)
transceiver module, which protects the computer from the influence of ground circulation and enhances the
system reliability in harsh environments.

2. Hardware Interfaces
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 CiAstandard. 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.

2.4 Terminal Resistance
As shown in Figure 2.3, the CAN channel of the PCIeCANFD-400U interface card has a built-in 120Ω terminal
resistance.The interface card uses the DIP switches S1_1, S1_2, S1_3, and S1_4 to select whether the terminal
resistance of the corresponding CAN0, CAN1, CAN2, and CAN3 channels is connected to the bus network. As
shown in Figure 2.4, set whether the CAN channel uses the 120 ohm terminal resistance. Before delivery, the DIP
switch is set to "ON" by default, that is, the 120 ohm terminal resistance is connected to the corresponding bus
network.
The interface card corresponds to the CAN channel at the endpoint of a CAN network. Set the DIP switch of
the corresponding channel to "ON", or connect a 120 ohm terminal resistance between CAN_H and CAN_L of the
corresponding CAN channel.

2.6 Board Installation
2.6.1 Precautions
PCIeCANFD-400U series interface cards are electrostatic sensitive products and should be packed in a
special anti-static protective bag before delivery. Therefore, when operating the interface card, take necessary
protective measures to ensure that the interface card is not damaged by human contact with static electricity.
The PCIeCANFD-400U interface card should be installed when the PC/industrial computer has been
powered off. Similarly, the interface card should also be disassembled when the PC/industrial computer is
powered off.
PCIeCANFD-400U series interface cards do not have any switches and jumpers for assigning interrupts and
I/O addresses, which are automatically assigned by the computer BIOS. Therefore, the board must be installed in
the PCI-E slot before you install the driver. The installation procedure is as follows:
1. Power off the computer and open the computer case cover;
2. Insert the PCIeCANFD-400U series interface card into a free PCI-E slot, x1, x4, x8, or x16 slot;
3. Tighten the screws to fix the board;
4. Power on the computer. At this time, the BIOS automatically assigns interrupts and I/O addresses to the
PCIeCANFD-400U interface card;
5. Install the driver.
Figure 2.6 Removing and inserting the PCIeCANFD-400U series CAN interface card
Note: Do not remove or insert the PCI-E interface card with power on; do not touch the device with your hands
during installation to prevent static electricity from damaging the device.
2.6.2 Product Dimensions
The physical dimensions of PCIeCANFD-400U are 117 mm x 120.02 mm (including metal baffle). Figure 2.6

2.7 System Connections
When the PCIeCANFD interface card is connected to the CAN-bus bus, it is only necessary 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 120 ohm terminal resistors; if the number of nodes is greater than 2,
the intermediate nodes do not need to install 120 ohm terminal resistors. For branch connections, the length
should not exceed 3 meters. Figure 2.2 shows the CAN-bus connection.

User Manual
In the CAN-bus network, shielded wires are often used for interconnection, so as to enhance the
anti-interference ability. However, there are many types of shielded wires and field wiring is complicated.
Therefore, the wiring diagrams of different types of cables in application are shown below, including the
connection diagrams of double-core single-layer shielded wire, double-core double-layer shielded wire, and
three-core single-layer shielded wire (The "equipment iron shell" in the pictures refers to the outer shell of the
device, which is grounded by default). Regardless of the type of cable, reasonable changes must be made
according to the complexity of the field wiring. Ensure the reliable grounding of the single point of the shielded
wire or ground wire at any time, and carry out on-site wiring in strict accordance with the wiring specifications to
minimize communication errors and abnormalities, and improve the communication quality and service life of the
bus.
