3. Access the web interface via browser (default login: username “admin”, no password).
4. Configure network parameters (IP, subnet mask, gateway).
5. Set serial port parameters (baud rate, parity, stop bits, socket port).
6. Save and reboot the device to apply settings.

Testing Procedure:
- Use HyperTerminal or similar software.
- For RS-232: Short DB9 pins 2 and 3 for loopback test.
- For RS-422: Short T+ to R+ and T– to R–.
