[QUOTE=che57vy;405308 I installed a Xantrex Prowatt but the remote cable for the old RS400 will not work on the new Prowatt inverter. [/QUOTE]
Contact Xantrex Prowatt support and ask them for the pin-outs of the cable/connector, for the old unit and the new unit. It probably looks like the old (remember them) land line cord ends. My guess is that it would be a very easy job to just rewire the cable end to match the new wiring.
I would not use the remote until you find out if it is different wiring or if maybe your remote went bad.
If you are going to wire in a switch, you may want to install one of these?
