1. Functions
MiniPCIeCAN-II is a high-performance MiniPCIe interface CAN card launched by
ZLG Electronics, which can connect the CAN network to a computer equipped with a
MiniPCIe card slot. MiniPCIeCAN-II adopts the MiniPCIe board in standard dimensions
and can be easily installed on laptop or industrial computer with MiniPCIe interface,
making it a powerful CAN analyzer.
MiniPCIeCAN-II integrates two CAN interfaces. In addition, to facilitate expansion, the
second function pin of the CAN signal can be switched to the reserved IO port of the
MiniPCIe interface by using the resistor R24, which helps the user design the CAN
transceiver circuit on the backplane.
The MiniPCIeCAN-II high-performance CAN interface card can be used to connect
the PC to the CAN-bus network through USB bus, which constitutes a CAN-bus network
control node for data processing and data acquisition in CAN-bus network fields such as
fieldbus laboratories, industrial control, high-performance residential areas, and
automotive electronic networks.
The MiniPCIeCAN-II high-performance CAN interface card is a powerful tool for
CAN-bus product development and CAN-bus data analysis; moreover, it features small
size, plug and play, etc. It is ideal for portable system users.
The MiniPCIeCAN-II high-performance CAN interface card supports Windows
2000/XP/7/8/10 and other operating systems and Linux operating systems.
MiniPCIeCAN-II provides a unified application programming interface and complete
application demonstration codes, including VC, VB, Delphi and C++ development routine
demonstrations, which helps users develop application programs.
The MiniPCIeCAN-II interface card supports the CANTest general test software,
which can perform functions such as sending, receiving and monitoring CAN-bus
messages. Figure 1.1 shows the product.
The MiniPCEeCAN card uses the USB D+ and USB D- signal cable in the MiniPCIe
slot. Before purchasing and using the product, check whether the MiniPCIe slot on the
motherboard provides USB D+ and USB D- signal pins. See Table 2.3 for pin numbers.
This CAN card cannot be used if the USB signal pin is missing from the motherboard slot.

2. Equipment Installation
2.1 Power Supply
MiniPCIeCAN-II uses the MiniPCIe interface 3.3V power supply. The SYS indicator is
on, and it turns red first, indicating that the device has power supply. It then flashes a few
times and turns green, indicating communication with the PC.
2.2 Signal Indicators
The MiniPCIeCAN-II interface card has one dual-color SYS indicator, one dual-color
CAN0 indicator, and one dual-color CAN1 indicator, which indicate the running status of
the device. Table 2.1 lists the functions of the indicators. When the indicators are in
various states, the status of the CAN bus is shown in Table 2.2.

After the MiniPCIeCAN-II interface card is powered on, the system initialization status
indicator SYS is red, indicating that the device has been powered and the system is
initializing;If the system initialization status indicator SYS is off, a system power fault or
serious system error occurs.
After normal connection to the PC (driver installed), the SYS indicator is green. When
data is being transmitted on the USB interface, the USB signal indicator SYS flashes in
green.
When CAN1 and CAN21 indicators are green, the CAN controller has been initialized
and is working properly.
When the CAN controller has an error, the CAN1 and CAN2 indicators are red; when
the error of the CAN controller is cleared, the CAN1 and CAN2 indicators are green.

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.
Figure 2.2 CAN signal secondary function selection resistor
The second function pin of the CAN signal is switched by using R24 (this resistor can
be found on the rear of the board, as shown in Figure 2.2). R24 is welded by default. The
system uses the default on-board CAN transceiver ADM3053. When R24 is removed, the
second function pin of the CAN signal is automatically enabled when the system is
powered on. The following table lists the pin sequence. 错误!未找到引用源。 At this time,
R29 and R30 need to weld 0 ohm resistors to enable CAN0, while R31 and R32
respectively weld 0 ohm resistors to enable CAN1.
