Applications

The MODIG RS485-ETHERNET PoE Converter enables bidirectional data transmission between an RS485 interface and an Ethernet network. Communication can be established between two MODIG RS485-ETHERNET PoE devices or by integrating other third-party equipment that supports TCP and/or UDP protocols. The built-in Power over Ethernet (PoE) system significantly simplifies installation within modern network infrastructures.

RS485 data frames are seamlessly converted into Ethernet TCP/UDP packets. For large data payloads (exceeding 1.5 kB, up to a maximum of 4 kB), an automated fragmentation mechanism splits the data into smaller frame sizes. At the destination device, the original RS485 data frames are reconstructed, ensuring completely transparent data transmission.

Typical application of the MODIG RS485-ETHERNET PoE converter:
