Description

Thanks to the use of the latest technologies, the MI400e-RD series allows you to install easily and quickly your industrial RS422/RS485 network while making advantage of an increased reliability.

The automatic RS485 line turn-around function contributes to the simplicity of the product installation; the MI400e-RD series automatically detects the direction of the serial data and is totally independent of the communication protocol. Its original mechanism of self configuration frees you from the tiresome operation which consists in the serial parameters setup.

Its dual port feature also makes it possible to connect two RS232 serial devices to a single RS485 bus. 

The MI400e-RD series accept 2 and 4 wires RS422/485 connection, for up to 1200m and support up to 32 bus connected equipments. 

Its small size, design features and its great adaptability make it a really universal product capable to fit in all the needs of the industry.
