4.1 드라이버 설치

The Plinkwirekb 2-in-1 USB to RS485 RS232 Serial Converter utilizes genuine FTDI chipsets, which typically allow for plug-and-play operation on most supported operating systems (Windows, MacOS, Linux, Android). The necessary Virtual COM Port (VCP) drivers are often installed automatically when the device is first connected.

• 윈도우: Connect the device. Windows Update should automatically find and install the drivers. If not, you can manually download the latest FTDI VCP drivers from the official FTDI web사이트 (www.ftdichip.com/Drivers/VCP.htm).
• 맥 OS: Drivers are generally built-in or automatically installed. If issues arise, refer to the FTDI website for specific MacOS driver instructions.
• 리눅스: Most modern Linux distributions include FTDI VCP drivers in their kernel. No manual installation is typically required.
• 기계적 인조 인간: Requires an OTG (On-The-Go) compatible device and an application that supports serial communication. Drivers are usually handled by the Android OS.

4.2 물리적 연결

1. Connect the USB-A male connector of the adapter to an available USB 2.0 port on your computer or host device.
2. Observe the Power LED indicator on the adapter. It should illuminate, indicating the device is receiving power.

4.3 Wiring the 5-Pin Terminal Block

The converter features a clearly labeled 5-pin screw terminal block for connecting your RS232 or RS485 devices. The pitch of the terminal block is 3.81mm.

Figure 3: Clearly labeled 5-Pin Screw Terminal Block.

Refer to the pin assignments below for correct wiring:

• A+ (RS485 Data+): Connect to the Data+ line of your RS485 device.
• B- (RS485 Data-): Connect to the Data- line of your RS485 device.
• GND(접지): Common ground for both RS232 and RS485 communication.
• TX (RS232 Transmit Data): Connect to the RX (Receive Data) pin of your RS232 device.
• RX (RS232 Receive Data): Connect to the TX (Transmit Data) pin of your RS232 device.

Ensure all connections are secure to prevent intermittent communication.

5. 사용 설명서

5.1 Identifying the COM Port

After connecting the converter and installing drivers, your operating system will assign a Virtual COM Port (VCP) number to the device. You can find this in:

• 윈도우: Device Manager > Ports (COM & LPT). Look for "USB Serial Port (COMX)".
• 맥 OS: System Information > Hardware > USB. The device will appear as a USB Serial Converter. The port will typically be `/dev/cu.usbserial-XXXX`.
• 리눅스: Use `ls /dev/ttyUSB*` in the terminal. The device will appear as `/dev/ttyUSB0` (or similar).

5.2 소프트웨어 구성

Use your preferred serial communication software (e.g., PuTTY, RealTerm, minicom, custom applications) to configure the COM port settings to match your connected serial device:

• COM Port Number: Select the VCP number identified in Section 5.1.
• 전송 속도: Common rates include 9600, 19200, 38400, 57600, 115200 bps.
• 데이터 비트: Typically 8.
• 패리티 : None, Even, Odd.
• 중지 비트 : Typically 1.
• 흐름 제어: 없음, 하드웨어(RTS/CTS), 소프트웨어(XON/XOFF).

5.3 LED 표시등

The converter is equipped with LED indicators to monitor communication status:

• 전원 LED: Illuminates when the device is powered via the USB port.
• TXD LED (Transmit Data): Flashes when data is being sent from your computer through the converter.
• RXD LED (Receive Data): Flashes when data is being received by the converter from the connected serial device.

6. 유지관리

To ensure the longevity and optimal performance of your Plinkwirekb serial converter, follow these maintenance guidelines:

• 저장: 본 기기는 직사광선과 극한의 온도를 피해 시원하고 건조한 곳에 보관하세요.
• 청소: 기기 외부를 닦을 때는 부드럽고 마른 천을 사용하십시오. 액체 세척제나 용제 사용은 피하십시오.
• 손질: 기기를 조심스럽게 다루십시오. 떨어뜨리거나 강한 충격을 주지 마십시오.
• 사이: Periodically check the terminal block screw connections to ensure they are secure.

7. 문제 해결

If you encounter issues with your serial converter, refer to the following troubleshooting steps:

• 장치가 감지되지 않음:
  • Ensure the USB connector is fully inserted into the USB port.
  • Try connecting the converter to a different USB port on your computer.
  • Verify that the necessary FTDI drivers are installed correctly (refer to Section 4.1).
  • Check if the Power LED illuminates when connected.
• 데이터 전송/수신 없음:
  • Confirm that the terminal block wiring (A+/B- for RS485, TX/RX for RS232, and GND) is correct and secure.
  • Verify that the COM port settings (baud rate, data bits, parity, stop bits, flow control) in your serial communication software match those of your connected device.
  • Check the TXD and RXD LEDs. If they are not flashing during expected communication, there might be an issue with the software configuration or the connected device.
  • Ensure the connected serial device is powered on and functioning correctly.
• 간헐적인 연결:
  • 모든 케이블과 연결부가 헐거워지거나 손상된 부분이 있는지 점검하십시오.
  • Avoid using excessively long or low-quality USB extension cables.
  • Ensure there is no electromagnetic interference from other devices.
