3.1 Driver fifi sori
The converter cable utilizes a CH340 chip. Before connecting the cable, ensure the appropriate CH340 driver is installed on your operating system. Drivers are typically available from the manufacturer's website or can be found by searching for 'CH340 driver download'.
3.2 Nsopọ USB
- So opin okun USB-A pọ si ibudo USB ti o wa lori kọnputa rẹ.
- Identify the 4-way female socket header. This header provides the following connections for your RS485 device:
- A (RS485 A): Data A line for RS485 communication.
- B (RS485 B): Data B line for RS485 communication.
- VCC (5V): 5 Volt power supply output.
- GND: Asopọ ilẹ.
- Connect the 4-way female socket header to your RS485 Modbus device, ensuring correct pin assignments (A to A, B to B, VCC to VCC, GND to GND). Refer to your device's documentation for its specific pinout.

4. Awọn ilana Iṣiṣẹ
Once the cable is physically connected and the drivers are installed, your computer will recognize the device as a virtual COM port. You can then use serial communication software (e.g., PuTTY, RealTerm, or custom applications) to interact with your RS485 Modbus device.
- Open your preferred serial communication software.
- Select the COM port assigned to the WITMOTION USB to RS485 converter. You can find this in your computer's Device Manager (Windows) or by listing serial devices (Linux/Mac).
- Configure the serial port settings to match your RS485 Modbus device's requirements. Key settings include:
- Oṣuwọn Baud: Set between 300 bps and 1.5 Mbps (e.g., 9600, 19200, 115200).
- Data Bits: Typically 8.
- Iṣọkan: None, Even, or Odd.
- Duro Awọn idinku: Typically 1 or 2.
- Initiate communication with your RS485 Modbus device according to its protocol specifications.
