To remote my FC-40 I use Ethernet cables with DIN to RJ adapters. I bought the male and female DIN connectors with short pigtails from W4RT and the Ethernet cables and connectors from Home Depot. The RJ connectors come in a small plastic box for surface mounting on a wall, like the old wired phone jacks. I just ran the DIN connector wires to the screw terminals in the RJ connector boxes.

I have used two 100’ cables with a double female RJ connector between them and it worked great at 200’ total length. Just watch out for all the swapping of wires in Ethernet cables – it’s been too long since I built mine and I don’t remember if the wires cross.
