5. 운영
Once the converter is set up and connected, it operates as a transparent bridge between your USB host and the connected serial device. The onboard automatic transceiver circuit manages data flow without manual intervention.
LED 표시등:
- PWR(빨간색): Indicates power. Lights up when the USB connection is established and voltage가 감지되었습니다.
- TXD (Green): Transmit Data Indicator. Lights up when the USB port sends data.
- RXD (Green): Receive Data Indicator. Lights up when the device ports send data back.
To communicate with your serial device, use appropriate serial communication software on your computer. Configure the software with the correct COM port (assigned by your operating system), baud rate, data bits, parity, and stop bits to match your serial device's settings.
