WHY IS THIS SO CONFUSING?!

[MSB123]

AM I MISSING SOMETHING?
I have these things:
Gyre xf250
Apex JR
Icecap Gyre interface Module
Icecap Backup Battery
WHAT AM I MISSING?
I want to connect my gyre to my apex, and/or my gyre to the backup battery. How do I do it? I've been watching youtube videos on it for like 5 hours and my head is spinning and I cant type properly, Thank goodness for Grammarly. So, my question is, How can Connect my gyre to my battery, and also to my apex if possible.
Thanks for listening to my rant,
MSB

I haven't done this but here is my understanding.

The battery backup power supply gets plugged in.
The pump power supply gets plugged into the wall and to a Y splitter. One side of the splitter goes to the battery the other to the Icecap interface module.
The Gyre gets plugged into the Icecap interface module.
The Apex connects to the small port on the side of the interface module.
