Operating Instructions

Once the adapter is successfully installed and connected, it functions as a virtual serial port on your computer. Applications designed to communicate with serial ports can now use this virtual port.

• Identifying the COM Port: After installation, open your computer's Device Manager (usually found in Control Panel > System and Security > Device Manager). Expand the 'Ports (COM & LPT)' section to find the assigned COM port number for your USB to Serial adapter (e.g., COM3, COM4).
• Software Configuration: Configure your serial communication software (e.g., HyperTerminal, PuTTY, or specific device software) to use the identified COM port number and the correct serial communication parameters (baud rate, data bits, parity, stop bits, flow control) as required by your connected serial device.
• Remote Wake-up and Power Management: The adapter supports remote wake-up and power management features. Ensure these settings are configured correctly in your operating system's power options and device properties if you intend to use them.
