COMMUNICATIONS
• A front mounted RS232 and a rear RS485 port
allow easy user interface via a PC.
• ModBus ® RTU protocol is used for all ports.
• The relay supports baud rates from 300 to 19,200
bps.
• Up to 32 MIF II relays can be addressed on a
single communications channel. A unique address
must be assigned to each relay via a setting when
multiple relays are connected.
Access to Information - Serial Communication and ModBus RTU Protocol
