- Compatible with standard network APIs (Winsock, BSD Sockets).
- Supports Virtual COM port emulation for legacy software integration.

Operation Modes:
- TCP Server Mode: Listens for incoming connections from clients.
- TCP Client Mode: Initiates connections to a remote server.
- UDP Mode: Transmits data using connectionless UDP protocol.
- Virtual COM Mode: Emulates a serial COM port over the network.
- Pairing Mode: Directly links two converters for serial data tunneling.

### 6. Installation & Setup

Power Connection:
Connect the supplied or optional DC adapter (9–24 VDC, 500 mA) to the DC jack. Ensure correct polarity (inner positive, outer negative).

Network Connection:
Connect the RJ-45 Ethernet port to a network switch or hub. The LAN LED will illuminate upon successful link detection.

Serial Connection:
Attach the RS-232 or RS-422/485 cable to the corresponding port. Ensure correct wiring per pinout specifications.

Reset Procedure:
If configuration becomes inaccessible, press and hold the reset button for 3–4 seconds to restore factory defaults. Holding longer than 5 seconds enters firmware update mode.

Configuration Steps:
1. Install and run the IP search utility “EX9132CST.exe” on a Windows PC.

3. Access the web interface via browser (default login: 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.
