Configuring Relay Data Communication

Using the keys on the relay fascia scroll down the settings menu's into the 'communications' menu and change
the settings for the communication port used on the relay. All of the below settings may not be available in all

COM1 – Standard RS485 Rear Port
COM2 - USB Port
LAN – Optional Ethernet Ports

Configuring Relay Protection Communication Address.

Using the keys on the relay fascia scroll down the 'Settings' menu into the 'Prot'n Comms' menu and 'Protection
Comms' sub-menu to change the 'Prot'n Address'. The sum of the addresses of both relays must add to 255. This
number must be divided between the relays typically as e.g. 1 & 254 or 2 & 253 or 3 & 252... etc.
