1. Product Introduction
1.1 Product Overview
USBCANFD-200U (100U) is a high-performance CANFD interface card developed by Guangzhou ZLG
Electronics. It meets the USB2.0 bus specification and integrates two CANFD interfaces (100U integrated one
CANFD interface). The CAN channel integrates an independent electrical isolation protection circuit. The interface
card connects the PC to the CAN(FD) network over the USB port to form a CAN(FD)-bus control node.
The USBCANFD-200U(100U) high-performance CANFD interface card is a powerful tool for CAN(FD)-bus
product development and CAN(FD)-bus data analysis; the USBCANFD-200U(100U) interface card has its own
electrical isolation module, which prevents the interface card from being damaged due to ground circulation and
enhances the system reliability in harsh environments. The USBCANFD-200U(100U) high-performance CAN
interface card supports operating systems such as Windows 7/Windows 10.
Note: USBCANFD-200U (100U) is collectively referred to as USBCANFD interface card below.

1.4.2 Operating Temperature
The USBCANFD interface card meets the requirements of industrial grade products, and its applicable
working temperature range is –40°C to +85°C. Using the interface card in too low or too high ambient temperature
will shorten its service life.
1.5 Mechanical Installation Dimensions
The external dimensions of the USBCANFD interface card are 115 mm x 80 mm x 35 mm, as shown in Figure

2. Hardware Interfaces
2.1 Power Cable Connection
The USBCANFD interface card is designed with two power supply methods. One is to supply power through
the USB port, and the other is to supply power through DC power supply. You can select one of the power supply
methods. You can also connect DC power supply and USB cable at the same time. The external power supply
mode is suitable for situations where the PC uses a USB bus hub, or is connected to multiple USB terminal devices,
which prevents USB port from providing sufficient current to the USBCANFD interface card.
The USB cable is type B (square opening), with locking screws at both ends of the cable. One USB cable is
provided before delivery. The DC socket is suitable for a round plug with an outer diameter of 5.5 mm, and there
is no positive or negative requirement for the plug inside and outside. The DC power supply and its cables need
to be provided by the customer, and the DC power supply meets +9 V to +48 V. Figure 2.1 shows the DC power
interface and USB interface.

2.2 CAN Communication Interface
A DB9 connector is used for the CAN communication interface of the USBCANFD interface card, and the
signal definition of the interface pins meets the requirements of the CiA standard. Table 2.1 lists the pin signal
definition of DB9, and Figure 2.2 shows the interface,

2.3 Signal Indicators
The USBCANFD-200U interface card has one power indicator PWR and one two-color SYS indicator. Each
two-color indicator corresponds to one CAN channel, indicating the operating status of the CAN channel. Figure
2.1 shows the location of the equipment indicator, and Table 2.2 lists the specific indicator function definition.

CAN_L to CAN_L and CAN_H to CAN_H signals. A linear topology is adopted for the CAN-bus network , 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 2.3 shows the connection of CAN-bus bus.
Figure 2.3 Linear topology of the CAN-bus network
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.
