Tether fathom cable connection

Hi
I am just assembling my bluerov2 and I need some help with the tether cable. How do I connect the cable with my pc?

You should have one of the Fathom / Fathom X boards on either end of the tether, one in your ROV, and one next to your computer. A network cable goes from the fathom board near your computer to the computer. and the other end goes from the other fathom tether into your ROV control board, probably the Raspberry PI

Thank you very much. This was exctly waht I needed. I appreciate your quick response.
