CGEM HC Questions
#1
Posted 22 June 2010 - 03:03 PM
So, tired of this I called Celestron and I was politely told I needed to RMA the controller for replacement and it would take upwards of 20+ business days for turn around including shipping time. I explained to the Celestron tech that I found this very inconvenient as I would be without the use of my mount for almost a month and I expected better from a company I had given $1400 to for a mount, granted not the high end, but this is not a popcorn maker either. They would not entertain cross shipping me a controller, even though I offered to provide a CC # they could charge if I failed to ship back the defective controller!
So, here are my questions:
1) I have a flashable HC for a CG5 GoTo mount that I am not using. Can I flash that to use with my CGEM while my HC is visiting Celestron?
2) Has anyone here re-crimped their Nexstar controller cable? I can see the wire pattern. It looks like a six pin jack with no wire attached to pin 1 followed by brown, red, green, yellow blue. Not that I am going to do this, as I am sure it would void my warranty!
Thanks,

I have a 5 month old CGEM mount ....
...lots of fun after you just did the 2 star align and added 4 calibration stars! ....
When you lose power on the mount and then regain it, hit the "Align" button and scroll to "Last Alignment." That'll restore your last alignment.

As far as I know, the HC is the same so you should be able to flash it as long as it's a version 4.xxx.

It's not an easy task even with a crimp tool unless your practiced at it. Crossing one of the pins in the process can blow a motor board. A new HC costs about $150. I'd call Celestron since it's under warranty.

You should be able to flash your CG-5 controller to use with your CGEM

I'm sure I'll be quickly corrected, but I believe the Hand Controller hardware for the CG-5, CGEM, CGE and CGE-Pro are all the same.
Yes. So is the firmware so it shouldn't require any reprogramming.

Works like a charm.

The hand controller are interchangeable. I was sent a new replacement for my defective CGEM under warranty. It was flashed for a CG5 with instructions to flash it for my cgem.

Yup. You don't really have a choice; there's only one firmware rev for all German EQ models so if it's programmed for one it's programmed for 'em all.

Thanks Fred. I have tried that, and sometimes it works...other times the goto alignments seem to be off..weird!

John, you always have the right answer. I plugged in the HC from the CG5 and powered on the CGEM and it comes right up with "Initializing...CGEM ready"! The bonus is the mount does not reset when I wiggle the wire!
Thanks again everyone!
