I completely understand that. I'm looking at controlling a RO VarioS pump. It would be very simple for anyone to purchase the
Icecap Y Module Cable, snip off the RJ45 and wire it right up to the LBF-AP. It is a pretty straight forward process.
On the other hand. I have access to a full electronics shop and it would be quite easy for me to make a Y cable with a RJ12 plug and dual 3.5mm plugs(For dual pumps down the road), but only if I knew what the pin outs were. That was the reason that I was asking. It is a more difficult process than modifying/using existing equipment, but would be kind of fun(and nearly free) for me to make my own cables.
