5.1 COM Port Retention

The adapter features COM port retention, meaning that once a COM port is assigned to a serial device, it will retain that assignment even if the adapter is disconnected and reconnected, or if the computer is restarted. This ensures consistent configuration for your serial applications.

5.2 ຕົວຊີ້ວັດ LED

The central hub of the adapter includes LED indicators to monitor activity:

• PWR (ພະລັງງານ): Indicates that the adapter is receiving power from the USB port.
• RXD (ຮັບຂໍ້ມູນ): Flashes when data is being received by the adapter from a connected serial device.
• TXD (ສົ່ງຂໍ້ມູນ): Flashes when data is being transmitted by the adapter to a connected serial device.

These LEDs allow for easy monitoring of data flow and can assist in troubleshooting connection issues.
