작동 지침
Once the adapter is physically connected and drivers are installed, your computer should recognize the new serial port. You can then use software applications that require serial communication to interact with your connected peripheral device.
- Identifying the COM Port: After installation, check your computer's Device Manager (Windows) or System Information (macOS/Linux) to identify the assigned COM port number for the USB to Serial Adapter. This port number will be used by your serial communication software.
- Configuring Software: Open your serial communication software (e.g., PuTTY, Tera Term, HyperTerminal) and configure it to use the identified COM port. Set the appropriate communication parameters such as baud rate (data transfer rate), data bits, parity, stop bits, and flow control, matching the requirements of your serial peripheral device. The adapter supports customizable data transfer rates between 75 bit and 128,000 bit per second.
- 데이터 교환: Initiate data exchange through your software. The adapter will facilitate the communication between your computer's USB port and the serial device.
