1.2 Configuration

The GP Gateway is simply configured by connecting a CAT5 patch cable between the Ethernet port of the
gateway and a laptop / PC with a static IP address in the range of 192.168.0.xxx.

Once the laptop / PC is configured, a web browser session can be started and the user can navigate to the
default IP address of the GP Gateway which is 192.168.0.101.

The web page that will be displayed allows the user to fully configure all IP settings and specify which controllers
are to be connected via RS485 to the device.

Once this has been completed the GP Gateway is ready to be installed.
