Apologies if this is a long post - I have a complex problem which I'd like to explain clearly.
I have a couple of issues with my LX200 GPS which may or may not be related to each other, and I'm hoping someone has a clue what is happening - as I don't !
I've seached all through various forums and other online sources, but I have no idea what's happening and how simple, complex or expensive the solution might be. I'd be eternally grateful if anybody recognizes what's happening.
- 15 year old 10" LX200 GPS, with an Autostar 2, running software version 2.0i.
- Recently pier mounted in a new observatory.
- I moved house and it's been in its box for 3-4 years until now. It hasn't had a lot of use as I was always working away.
- On a wedge and manually aligned North pretty well.
- After 2-star aligning to Arcturus then Altair, for example, if I then try to GoTo say M57, the scope points 20-30 degrees away- ie nowhere near the selected object. If I then try to go back to Altair, again I end up miles away.
- On start-up, GPS position acquision can take 10 mins and then isn't always successful.
- Even after Parking the scope before powering down, Date and Time are not saved upon reboot. Lat / Long / Site / Polar Mount / some other settings ARE saved though - which seems strange.
What I've Done:
As the scope has been out of use for a while, I changed the little CR2023 battery on the motherboard. If it had gone flat, I reasoned this could be why some settings aren't saved, which might then throw the whole alignment out.
- It didn't make any difference
I then reasoned that if the firmware / GPS software is out of date, that could be the problem. So I tried to upgrade it.
- My Win 10 laptop only has USB ports, so I have to use a USB / serial adapter to connect to the RS232 cable from the scope.
- Tried using both Meade ASU and Starpatch
- Laptop cannot detect the Autostar 2, regardless of what USB serial adapter and RS232 cables I use. I've tried 3 adapters and 2 different RS232 leads, including a Meade AutoSuite lead, which you'd think would work.
- I've downloaded adapter drivers, and connected cables and adapters to the 2 different scope RS232 sockets in every combination. I've also tried selecting different COM ports in the software. Nothing works.
So I don't know if out-of-date firmware is affecting positioning, if I have a dead GPS module - or both. Or there could be something else ?
I'd be eternally grateful for any help to point me in the right direction (pun intended...) - it's a nice scope and I've built a great little home for it - would be a shame if I can't get it to reliably find the objects I want to see and photograph - but I have no idea where the problem(s) actually lie.
Thank you in adavnce for any help offered.
