4. Functionality

The SE-110S functions as a transparent serial-to-Ethernet gateway, enabling serial devices to communicate over IP networks without requiring changes to existing serial software. It encapsulates serial data into TCP or UDP packets and transmits them over Ethernet, effectively extending the reach of serial communication across network infrastructures.

Operation Modes:
- TCP Server Mode: The SE-110S listens for incoming TCP connections from remote hosts, allowing multiple clients to access the serial device.
- TCP Client Mode: The module initiates a connection to a designated remote server, suitable for applications where the serial device must actively send data.
- UDP Mode: Provides connectionless data transmission for low-latency or broadcast applications.

Use Cases and Applications:
- Industrial automation and control systems
- Remote monitoring and data acquisition (SCADA)
- POS systems and kiosks
- Building management and environmental monitoring
- Legacy equipment networking and modernization
- Embedded OEM systems requiring Ethernet connectivity

Compatibility:
- Compatible with standard RS-232 devices such as PLCs, sensors, barcode scanners, and modems.
- Works with standard TCP/IP network infrastructure and management tools.
