1. 소개 및 이상view
The GODIYMODULES USB to CAN Bus Converter (TJA1051T/3 Non-Isolated version) is a versatile tool designed for CAN bus debugging and analysis. It facilitates communication between a computer and a CAN bus network, allowing for monitoring, sending, and receiving CAN data. This unit utilizes the TJA1051T/3 non-isolated CAN chip, supporting high baud rates up to 1 Mbps, and is compatible with open-source host computer software like Cangjaroo CAN for comprehensive protocol analysis.
2. 특징
- 칩셋: Integrates the TJA1051T/3 non-isolated CAN chip for reliable performance.
- 높은 전송률: Supports CAN bus baud rates up to 1 Mbps.
- 전원 공급 장치: Conveniently powered via a standard 5V USB port.
- 상태 표시기: Equipped with a three-color LED to display operational status.
- 소프트웨어 호환성 : Designed to work with open-source host computer software for CAN protocol analysis, such as Cangjaroo CAN.
3. 설정
Follow these steps to set up your USB to CAN Bus Converter:
- 종단 저항기: The device includes a jumper cap to enable or disable the internal 120Ω termination resistor. Insert the jumper cap if a 120Ω termination resistor is required for your CAN bus network. If not needed, ensure the jumper cap is removed.
- CAN 버스에 연결하세요: Connect the CAN_H and CAN_L terminals of the converter to the corresponding CAN_H and CAN_L lines of your CAN bus network. The GND terminal can be connected to the CAN bus ground if necessary, but it is often optional depending on your setup.
- 컴퓨터에 연결: Plug the USB connector of the converter into an available USB port on your computer. The device should be recognized by your operating system, and it will appear in the Device Manager.
- 소프트웨어 설치: Install the necessary open-source host computer software for CAN protocol analysis (e.g., Cangjaroo CAN). Ensure your operating system (e.g., Windows 10) is supported by the software.

4. 사용 설명서
Once the hardware is connected and the software is installed, proceed with the following steps to operate the converter:
- Launch Host Software: Open the installed CAN protocol analysis software (e.g., Cangjaroo CAN) on your computer.
- 전송 속도 설정: Within the software interface, select the desired CAN bus baud rate and sampling point that matches your CAN network's configuration.
- 장치 활성화: Click the "OK" or "Connect" button in the software to activate the connection. The three-color LED on the converter board will illuminate, indicating a successful connection and readiness for operation.
- Send and Receive Data: You can now use the software to send and receive data packets on the CAN bus. The software will display incoming messages and allow you to compose and transmit outgoing messages.
