Section 1: RA24 Arc Fault Monitor Configuration
1.1 Web Browser Session
Configuration of a RA24 can be undertaken either via direct connection to a PC or via a Lan.
If a direct connection to a PC is utilitised a crossover patch lead will be required to enable communication
with the RA24.
Whether the communication is direct or via a LAN, both the PC and the RA24 need to have IP addressing
within the same network.
With a subnet mask of 255.255.255.0 the first 3 octets of the IP address need to be the same for the PC
and the RA24 and the last octet needs to be unique, for example:
RA24 IP Address:
192.168.0
.220
PC IP Address:
192.168.0
.238
In the above example entering the RA24 IP Address (192.168.0.220) into the PC web browser address field
will establish a web browser session displaying the Relay Build Information and a menu tree to navigate to
the other configuration screens.
