Yes that is correct Mike, it will enable you to do everything from within the warm environment of your house.
It links everything you need to your comp in the house: the mount, the camera(s), filterwheel just name it.
You will be able to remotely control everything, within the working distance of your Icron Ranger.
Another option would be using teamviewer to control the óutside'computer through the in house one, but you will need an internet connection on both computers for that
The great advantage of the Icron is that you need only one computer. If you want to download on a stick first, you will need to have a computer outside, won't you?
On top of that you will need a fast high end stick or mobile HDD to store all the information fast and accurate.
You are in for a steep learning curve... Many things are not as easy as they look. But giving it some time and patience, you will have a lot of fun !
