See I told you other projects would pop up. Ian and I purchased a Sprog II each from the UK and it arrived earlier this week. We saw these at the New England convention with Gerry Hopkins and this will allow me to use Decoder Pro in my study without having to set up Bowen Creek. I am still learning Decoder Pro but why would you program your decoders without it, it just makes it so easy.
HERE. The other thing you will need is a power supply, I picked up one from Jaycar, part no. MP-3011 for $19.95. You just cut the plug off and place the wire with the white stripe to the +V and the wire with the writing to the 0V on the sprogII. The rest is straight forward.
Now just to clarify, you can use decoder pro linked from your computer to your command station but the SprogII just allows you to do it without it. You don't need the sprog unless you want to program decoders away from the layout.
