Fathom X wiring guidance

Blue Robotics Products Tether Interfaces

Hi all,

I think this is a very basic question, and searched for prior related answers + read related docs, but no luck.

I couple of years ago I took apart my Fathom-X unit, and now realize I lost my notes from the time. I would like to reconnect the tether wires to the tether board itself, but not sure on correct wiring.

Photo attached, and if anyone could provide guidance or point me to the correct docs, that would be superb. For example, if the white/blue wires running to the tether board are in positions 1A (white) and 1B (blue), into what positions do I plug in the other wires?

Thanks very much!

G’day RM,

Here is a photo of my setup with two Blue-White pairs connected (one pair for the ROV and a second pair for the Waterlinked UGPS).

The other coloured pairs can be left NC unless you are using them for signals.

Hi @xbertmx
Welcome back to the forums!
You can find that information here, as well as here.

The polarity of the blue and white wires actually doesn’t matter! Where wires go into that block also doesn’t matter - the pins on each side are bussed together. This lets multiple Fathom-X tether interface communicate over the same two wires, which is how the WaterLinked system @pforperry mentioned communicates.

Thanks very much @pforperry and @tony-white, this is very helpful!

I appreciate you both jumping in.
