I am currently out setting up my CG5-GT mount and whenever I turn the mount on it says “No Response 17” or “No Response 16” and the mount does not respond to the hand controller. If I turn the mount off and on again sometimes it allows me to input all the info (time, date.. ect) and begins to slew to my first alignment star.. then it says “No Response 17” or “No Response 16” and continues slewing on till I just have to switch the mount off to stop it crashing in to itself. The mount has done this before when I connected it the mains power supply. Since December I have been using the mount with a power pack (on numerous occasions) and ever had this problem again on till tonight. I permanently store the mount outside on a pier and cover it with a upside-down trash can that clips into place to create a water proof environment. Has anyone experienced this before or know what’s causing it?

Check the nextstar resource site for more info. www.nexstarsite.com Post Extras:       nemo129 Carpal Tunnel Reged: 01/03/10 Loc: WMass Re: Help- CG5-GT No Response 17 /16 [Re: Termo]       #4452421 - 03/15/11 08:54 PM Edit   Reply   Quote Quick Reply   As Gary said, it could be power. You might want to try gently spreading the center pin in the power socket on the mount. Cleaning the pins on the HC's RJ style connector is also a good idea. Yes I have had this issue. It turned out to be a bad crimp in the RJ style connector on the HC. Mine was under warranty and Celestron replaced it (3 week wait). If you have no warrantly, you could try recrimping the cable. Those two error codes (16 and 17) indicate communication loss between the HC and the motor controller chips for the DEC and RA axis. See here.

Last night was very humid here, as usual, so I went back out again after I posted this message and give everything a blast of the hairdryer. The mount worked seamlessly after this so maybe it was moisture in the connection sockets that was causing the problem? Anyway, thanks again for all your help.
