7. 유지관리

  • Keep the converter in a clean, dry environment.
  • Avoid exposing the device to extreme temperatures or humidity outside the specified operating range.
  • c를 열려고 시도하지 마십시오.asing or modify the internal components, as this will void the warranty and may damage the device.
  • 부드럽고 마른 천으로 외부를 닦으세요. 액체 세제는 사용하지 마세요.

8. 문제 해결

  • 전원 없음(PWR LED 꺼짐):
    • 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.
  • 간헐적인 연결:
    • 모든 케이블 연결 부분이 느슨하지 않은지 확인하세요.
    • Ensure the USB and RS232 cable lengths do not exceed the recommended distances (5m for USB, 15m for RS232).
    • 다른 전자기기의 전자파 간섭을 최소화하세요.
