Hooked up my old CN16 GPS unit to my Evolution mount. It registered the correct time and location, but the year showed 1/21/00! I went ahead and tried a Solar System alignment, but my target, the Moon, was not shown on the hand controller as being visible. Time to upgrade the GPS unit?

Yes

afraid it’s time for a upgrade.

i know there was a lot of chatter on the GPS glitch and a software update.

boy, just when you think the weather is getting mild, it’s almost 90 outside at 8:30 at night!

almost too hot to enjoy viewing.

Thanks. Well, this is the optimum time for my being particularly receptive to spending money on astro gear--- Friday night, after a typically stressful week, and the decompression booze has taken effect..

Hi,

 

You just need to update firmware on the hand control.  At the top of this forum, read the topic "Celestron GPS-Enabled Scope Displays a Date Several Years in the Past after GPS Link".

Woops..... now why didn't I see that pinned topic? I'm blaming it on age. Thanks Michael!

OK,  update performed on NexStar + HC, but CN16 still shows date of 1/21/00. I acquired a new Skysync unit and it works fine BUT I have to plug the HC into the HC port on the GPS unit itself for the unit to be recognized. I thought I could plug Skysync into any AUX port, and the HC into another AUX port, which is how my old CN16 worked. It's not a big deal to run it that way, I just want to know if that's right.

Just more complications....

 

Edited: Just plugged the Skysync unit into the AUX port on my 6SE, I get "No GPS Detected" when I try to enable GPS. I'm guessing I have a defective unit.

What version numbers are showing in the menu on the NexStar+ HC - the latest firmware should definitely fix the date coming out of the CN-16.

 

Regarding plugging things into various ports on Celestron's mounts - we've seen a lot of cases lately where only specific combinations work.  On some mounts (the Evolution for certain and some have reported the SE mount), Celestron has acknowledged subtle electronic differences which they may have a remedy for.  But, for most of us, rather than taking that route, we just find a combination that works for our scope and roll with it.  It is possible the SkySync is bad but it might be something with your mounts.  On the SE mount you could try the SkySync plugged into the HC port in the arm and the HC plugged into the AUX port to test.  And then the HC plugged into the extra port on the SkySync itself.

Thanks, Michael. I'll check the version numbers on the NexStar+ HC tonight if possible. I'm going to exchange the Skysync module for another one, if that one behaves the same then I'll assume it is the mounts and roll with it, as you say.

Sure appreciate all your help here!

Received the replacement Skysync, it works as it should. Can plug it into any aux port and it's recognized, on both SE and Evo mount. Also re-ran the HC update, that fixed the problem with CN-16. Thanks to everyone for all the help.
