I took delivery of a Lacerta MGENII auto guider last week, prompting redesign of the board. The RA DEC silkscreen is correct after all. In-fact, I managed to invert the RJ12 connector, which needed a little modification.
The latest version of the board is true to the MGEN ST-4 pin out. However, because the Tak has RA DEC reversion (hand controller) and I'm not completely sure which pin is plus and minus (though I feel sure I have that all sorted), I have included RA DEC reversion on the board. Basically, any pin can be set + or -.
Having done all that, the software should compensate and select +/- automatically regardless of physical pin allocation.
Anyway, just to be sure... the board can be matched to the weird and wonderful world of non-standard pseudo ST-4 variations, which is completely irrelevant except to owners of EM200B mounts who want autoguiding... WTS...
Some 3D parts don't exactly fit...
