ZWO EAF hand controller - request for someone to open theirs up and tell us whats inside

[powerlord]

Hi all,

I was wondering if someone with one, would open it up and tell us whats in it. My suspicion is very little - either nothing at all other than switches on the 4 input connections from the jack, or maybe a few resistors.

I'd be great to know so myself and others could make their own and save lining ZWO's pockets with 37 quid for, as ZWO put it 'a must have option' - so much 'must have; that the don't include it in the already massively overpriced 184 quid EAF itself.

I dont use this focuser but i once read this. 
Maybe here some info?

Someone mentioned:

So to sum it up, here's what I confirmed:

tip+ring1=up

tip+ring2=down

tip+sleeve=fast

Awesome!! Just as I thought, but was too chicken to try myself. I'll make a wee wee handset up and save myself 40 quid.
