3. ຄໍາແນະນໍາການດໍາເນີນງານ
Once the adapter is installed and recognized by your operating system, it functions as a standard serial COM port. Applications that communicate via serial ports can now interact with your connected serial device.
- COM Port Retention: A key feature of this adapter is COM port retention. This means that if you disconnect the adapter from your computer and then reconnect it, or if you reboot your system, the operating system will automatically re-assign the same COM port number to the adapter. This eliminates the need to reconfigure your serial communication software each time.
- ການຕັ້ງຄ່າຊອບແວຣ: Open your serial communication software (e.g., HyperTerminal, PuTTY, custom application) and select the COM port number assigned to the StarTech.com adapter. Configure the serial port settings (baud rate, data bits, parity, stop bits, flow control) to match those of your connected serial device.
- ການໂອນຂໍ້ມູນ: Initiate communication through your software. The adapter will facilitate the data transfer between your computer's USB port and the serial device.
