2.8.3 COMMUNICATION PORTS
The front RS232 and the rear RS485 port provide interface with the relay. All serial ports use the Modbus® RTU protocol
and may be connected to system computers with baud rates from 300 to 19200 bps. Up to 32 MIB relays can be connected
(daisy-chained) on the same communication circuit. Each relay must be assigned a different Modbus Address (using a
setting) if multiple relays are connected on the same circuit.

MIB units are supplied together with ENERVISTA MII SETUP software, a Windows
based software that allows
communication with the relay for data viewing and retrieval, as well as oscillography, I/O configuration and logical
configuration (in models where these features are available).
