Hi Tim;

I got the cable in the box along with my Celestron 9.25. It's a CG-5 mount. The cable
looks right - it's flat with the colored wires (BYGRBW) all separate and hooking into the six
contacts.
Just so I'm clear. The 6 pin RJ-12 cable that you connect up between the CG 5 and the GPUSB box came with the CG-5 mount, right? Or did it come with the GPUSB?
All the RJ-12 cables I tried to purchase in Calgary from multiple electronics supply houses were all twisted pairs. I had to buy a splicer RJ-45/12 tool, plugs and 6 pin flat cable and make my own straight through cables.
The only button that works is the Right and it seems to move in the right direction. I
thought at first the Up was working but it either stopped working or I misperceived. I
juggled and fumbled with the plug ends to no avail.
Okay - then it's probably a cable issue.
Yes I upgraded to the Astro 3.02. per advice here.
I figure if one direction moves, then it could be a contact problem. I looked briefly at the
plugs and I could do a little surgery. Will look closely at my mount contacts as well when I
have a chance.
It could also be a twisted pair cable versus straight through cable problem too.
That is unless you can think of something else. Could it be the GPUSB? I noticed that they
had a diagnostic tool on the Shoestring website but it is made for PCs. I don't suppose
there is a compatibility problem with my mac.
Nope, but if Astro IIDC detects any faults in the GPUSB hardware, it will tell you that.
It could be the GPUSB, but you should really make sure it's not the cable first.
The cable must be straight through and not twisted pairs. The easiest way to tell is if the plugs on both ends are transparent, then you can see what pins the 6 colored cables connect to. Orient the plugs so that they are the same sides up and look to see if the colored wires are the same from left to right on both plugs.
If you can't tell, you can use a volt meter with a batter or conductivity meter and test each pin on each end to see if they are connected or not.
