ETC response 4 port gateway configuration (not the Mk2)

Good Evening,

I have a Gio running 3.2.5 (i think) and a response 4 port gateway.

The gateway looks to have a dynamic IP address and I want to set it to a static IP. I exited the EOS software and went in to settings to start concert. The gateway does not show up under concert. The gateway does work but I want it to be static IP so we can have everything stable.

How can I set the IP on the gateway? I have searched the web and it shows a set up manual but it does not tell me how to do it.
