1. Product Introduction
1.1 Product Overview
CAN FD (CAN Flexible Data-rate) is the latest version of the CAN bus, with a maximum of 64 bytes of data,
and a flexible data field with a baud rate of up to 5 Mbps.
The MiniPCIeCANFD CAN(FD) interface card is a MiniPCIe to dual-channel CAN(FD) communication
interface card compatible with PCI Express r1.0a developed by Guangzhou ZLG Electronics. The
MiniPCIeCANFD interface card provides a peripheral controller interface for MiniPCI Express multi-function
devices, which enables the computer to be easily connected to the CAN/CAN(FD) bus network and monitor
multiple bus networks in real time. It is compact and can be easily embedded in single board computers (SBC),
portable industrial control hosts, and industrial notebooks. It is easy to install and easy to use.
The MiniPCIeCANFD provides two completely independent isolated CAN (FD) channels, in line with 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, MiniPCIeCANFD
interface card adopts 2,500 V DC electrically isolated CAN (FD) transceiver circuit, which protects the computer
from the influence of ground circulation and enhances the system reliability in harsh environments. To facilitate
expansion, the second function pin of CAN signals can be switched to the reserved PIN of the MiniPCIe golden
finger through jumper welding, which allows users to design CAN transceiver circuits on the baseboard by
themselves.
The MiniPCIeCANFD interface card provides a unified application programming interface and complete and
diverse application demonstration codes, including development routines such as VC, VB, Delphi and labview,
which facilitates application development. MiniPCIeCANFD supports OPC interfaces and can be used in
configuration software that supports OPC. In addition, we provide powerful ZCANPRO general-purpose
CAN-BUS test software for CAN/CAN (FD) message sending and receiving and monitoring, which facilitates
development and debugging.
Note: MiniPCIeCANFD is collectively referred to as PCIeCANFD interface card below.

2.3 Terminal Resistance
As shown in Figure 2.3, the PACK interface board attached to the MiniPCIeCANFD interface card has a
built-in 120 ohm terminal resistor.Use the DIP switch S1 to select whether the CAN channel terminal resistance 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.

2.4 CAN Second Function Pin Switch
When designing the CAN transceiver circuit or improving the protection level of the CAN signal cable,
consider connecting the second function pin of the CAN signal to the backplane through the MiniPCIe reserved
pin. Design the CAN transceiver circuit by yourself to improve the system flexibility.
The second function pin of the CAN signal is switched through the jumper JP1 (as shown in Figure 2.2). JP1
is disconnected by default, and the system uses the default on-board CAN transceiver. When JP1 is
short-circuited with solder, the second function pin of CAN signal is automatically enabled when the system is
powered on. Table 2.3 lists the pin definitions.

2.7 Board Installation
2.7.1 Precautions
MiniPCIeCANFD 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 MiniPCIeCANFD 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.
MiniPCIeCANFD 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 MiniPCI-E slot before you install the driver. Figure 2.3 shows the installation procedure:
1. Power off the computer and open the computer case cover;
2. Insert the end of the MiniPCIeCANFD series interface card diagonally upward into the free MiniPCI-E slot,
and then gently press it down;
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
MiniPCIeCANFD interface card;
5. Install the driver.
Figure 2.3 MiniPCIeCANFD installation
Note: Do not remove or insert the PCI-E interface card with power is on; it is forbidden to touch the device with
your hands during installation to prevent static electricity from damaging the device.

2.7.2 Product Dimensions
The physical dimensions of the MiniPCIeCANFD: 30 mm x 50.95 m, the highest device height on the top side
is 3.5-4.0 mm, and the highest device height on the bottom side is 1.75 mm, as shown in Figure 2.4.
Figure 2.4 Product dimensions
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.
Figure 2.5 Linear topology of CAN-bus network
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.

Therefore, the wiring diagrams of different types of cables in application are shown below, including the
connection diagrams of double-core single-layer shielded cable, double-core double-layer shielded cable, and
three-core single-layer shielded cable (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
cable 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.
