Anssen Alhena pinouts

[garymck]

Hi,

I'm having a play with an old Anssen Technologies Alhena mount.

The stepper driver controller that came with it has an ST4 autoguider jack. I believe, however that the pinouts are non standard.

Does anyone have a wiring diagram for this so I can see how it autoguides?

Any help much appreciated.

cheers

I am also using an Autoguider on an Alhena, but found that PHD guiding software thinks my Ra is Dec and visa versa. It is still guiding fine, but when you watch the graph, you have to remember that when it says it is moving in Dec, it is actually RA. I too would be very happy to actually wire it up correctly, so that I can use more features of PHS guide software. From what I can see, (but not yet game to wire it), it to make a cable to plug into the AT500 Alhena controller that swaps, pin 3,4 and 5,6, so that Ra and Dec are reversed on the 'in' pins of the RJ12 jack. Anyone have any thoughts? ( no 1 white is not used and no 2, black is ground)
