[g__day (Matthew)]

I was doing a remote imaging run yesterday when I noted that things had hung - so I went to the astro lab and power cycled everything. The SkySensor2000-PC driving the Vixen Atlux wouldn't boot initially - it just beeped once!

I left everything off for about 5 minutes and tried again and it started okay. It was late so I just shut everything down for a day.

Today I booted first the Sky 6 Professional edition, then Cartes Du Ciel beta v3.012 then Cartes v2.76 - none of them can see my SkySensor!

I check the protocol was LX200 at 9600 baud on com port one with the usual settings. I tried a second laptop. I check the serial cable with a mutli-metre - all okay.

Has anyone seen this before - what is the fix or better diagnostics?

Do I reset the hand controller or try something else?

All my gear is protected on a UPS into mains are there diagnostics or a way to determine what has gone bad?

The mount itself runs off a 12 volt DC 3 amp regulated power supply being feed from a 500 volt amp un-interruptible power supply (UPS) powering PC Mount and a Canon DSLR 400D - with all of this being powered from mains.

Does this behaviour sound like insufficient quality power?

Its concerning to see no response - or rather error code 1400 from the Sky6 - nothing seems to be attached - check power and cables.

Don't you love it when things go weird! Hopes its something simple and cheap to fix - not a handcontroller replace or fix!
