[TowerTalk] Prosearch Rotor Controller Info Needed

[Steve Harrison]

I just acquired a Prosearch controller, SN PSE1N2351, along with the 
transformer. But I have absolutely no info about what it is compatible 
with, how to hook it up, how to use it, etc. etc.. It looks very much 
like this one, which details you cannot really make out, as there's no 
light:

And as a matter of fact, I'm hoping to use it with an Alfa-Spid RAK-1 
rotator which I already have to turn my old, venerable Wilson 77-foot 
STB-77, which I hope to equip with 5L 20m and 15m yagis, much like that 
guy with the youtube video is doing.

Where can I find info on this box, please?

TNX,

Steve, K0XP
