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.
