4. Functionality

The WE-200M functions as a bridge between serial devices and Ethernet networks. It creates a transparent data channel that allows serial data to be transmitted over TCP/IP. The module can operate as a TCP server (listening for incoming connections), a TCP client (initiating connections to remote hosts), or a UDP node (for connectionless communication).

The integrated web server enables remote device management through standard browsers. Users can upload custom web pages, Java applets, or ActiveX controls to the module’s 64KB Flash memory, enabling interactive control interfaces.

Use Cases and Applications:
- Industrial automation and control systems
- Remote monitoring of serial-based sensors and instruments
- Legacy equipment network integration
- Building management systems
- Embedded device networking for OEM applications

Compatibility:
- Compatible with standard Ethernet networks (10/100 Mbps)
- Supports standard TCP/IP protocols for interoperability with PCs, servers, and network devices
- Works with Windows-based configuration utilities and Java-based management tools
