Need Atlas EQ-G controller board to DB9 pinouts
Posted 24 October 2013 - 09:30 AM
There is a 6-pin header on one end of the board connecting to a cable with 6 color-coded wires: grey (nearest the edge); black; red; orange; yellow; and green (beside the power switch connector).
Can anyone tell me which of these wires goes to which DB9 pin?
If anyone has this info (and, maybe, a circuit diagram as well) I would be most grateful! If anyone is willing to look at the pinouts in his own mount, that would work as well...
Many thanks in advance!

There's also a yahoo group called "EQ6" that covers the Atlas mount. A few posts and pics on blown boards and fixes/mods.

I really appreciate this... the photos are EXACTLY what I needed!!!
Just need to confirm a couple of pins, since a couple of the wires are hidden in the photos.
Looking at the rear of the DB9, there are two rows of pins... one row of 4 pins; and another row of 5. With the 5-pin row at the top, I have....
5-row: black, vacant, vacant, yellow, green
4-row: red, vacant, gray, orange
Is that correct?

I have to say, I'm terrible with colors, so it's up to you to verify them. But the new pics clearly show what pins are unused.
I also uploaded a few pics of the DB9 pin definitions.

Anyway, thanks to your photos, I think I've figured this out... and I am very grateful to you for your help!
