I have a single pair of wires spare available from a subsea unit to surface and need to try and get a RS485 and video signal onto the single pair. I was hoping to use a pair of Fathom S cards to get the two signals presented on the Ethernet plug and then convert Ethernet to a 2 wire signal using a pair of Fathom X boards in between the Fathom S boards. Is this feasible/possible? I appreciate the TTL has to be converted to RS485 and have sourced suitable converters.
In the documentation there is a description to link the Tether X into the Tether S and then use the normal Tether S connection but I don’t have enough wires?
Any advice greatly appreciated.
