7. Bảo trì
- Keep the converter in a clean, dry environment.
- Avoid exposing the device to extreme temperatures or humidity outside the specified operating range.
- Không cố gắng mở casing or modify the internal components, as this will void the warranty and may damage the device.
- Lau sạch bên ngoài bằng vải mềm, khô. Không sử dụng chất tẩy rửa dạng lỏng.
KHAI THÁC. Xử lý sự cố
- Không có nguồn (Đèn LED nguồn tắt):
- Check if the USB cable is securely connected to both the converter and the host device.
- Verify that the host device's USB port is functional.
- Ensure the power adapter is correctly connected and providing power within the 5-36V range.
- No Data Transmission (TXD/RXD LEDs off during communication):
- Confirm that the RS232 devices are properly connected to the converter's DB9 ports.
- Verify that the RS232 devices are powered on and configured correctly.
- Check your software settings on the host computer to ensure the correct COM port is selected and communication parameters (baud rate, data bits, parity, stop bits) match those of the RS232 device.
- Ensure the drivers for the FT4232HL chip are correctly installed.
- Kết nối không liên tục:
- Kiểm tra tất cả các mối nối cáp xem có bị lỏng không.
- Ensure the USB and RS232 cable lengths do not exceed the recommended distances (5m for USB, 15m for RS232).
- Giảm thiểu nhiễu điện từ từ các thiết bị điện tử khác.
