The MU-1052M is special LAN<=>RS-485 communication converter designed primarily to integrate MicroUnit series modules (or large group of modules) into Ethernet.

The converter operates as Modbus TCP / Modbus RTU gateway, but can be simultaneously use as Modbus RTU repeater (e.g. for interconnecting two Modbus RTU segments operating at different communication speeds).

The MU-1052M converter is equipped with...

For supervision in operating mode, the converter is equipped with a web interface through which diagnostic data can be monitored. The same function offers the Modbus RTU slave interface.

The MU-1052M converter can be configured with the supplied program via LAN or Modbus RTU slave interface, both interfaces can also be used for user friendly remote firmware upgrade without without having to touch the module.

Software support

For typical applications based on Modbus RTU/TCP protocols, there is no need to use specific software drivers, because almost any general software support for this protocol can be used.
