### 4. Functionality

The IP102 acts as a transparent bridge between serial devices and Ethernet networks. It converts asynchronous serial data into TCP/IP or UDP/IP packets for transmission over LAN/WAN and vice versa.

Primary Use Cases:
- Industrial automation (PLC, CNC, SCADA systems)
- Factory and warehouse control
- Medical and laboratory instrumentation
- Security and access control systems
- Transportation and logistics equipment
- Barcode scanners, weigh scales, and data loggers

Operating Modes:
1. Direct IP Mode:
- The IP102 operates as a TCP/UDP server.
- Socket-based applications connect directly to the serial port via IP and port number.
2. Virtual COM Mode:
- Installs a virtual COM driver on Windows PCs.
- Applications communicate as if the serial device were locally connected.
3. Paired Mode (Serial Tunneling):
- Two IP102 units form a virtual serial cable over Ethernet.
- One configured as TCP/UDP client, the other as server.
4. Heartbeat Function:
- Automatically re-establishes lost connections every 5 seconds.

Compatibility:
- Windows 95/98/ME/NT/2000/XP/2003
- Supports Winsock API applications and virtual COM drivers
