I am using a QHY8 camera with Windows XP Pro and Nebulosity Ver. 2.5.
The camera sometimes operates erratically producing images that are a mess of scrambled colours. I have tried reinstalling the drivers but the problem remains.
The driver details are shown in Windows Control Panel as:
C:\WINDOWS\system32\DRIVERS\WinUSB. sys
C:\WINDOWS\system32\WdfColnstaller0 1005/dll
C:\WINDOWS\SYSTEM32\WinUSBColnstall er.dll
I would like advice on:
1. Where to obtain the currently best drivers.
2. How to uninstall the present drivers
3. How to install the new drivers.
I suspect that my previous attempts to get new drivers has
not substituted them for the old drivers.
Otherwise, are there any other suggestions regarding the camera problem other than a drivers?
FWIW, recently re-installed QHY8 drivers from the QHYCCD site for win8 - worked ok under Nebulosity and the install process seems to include a removal step that presumably clears out all history.
might be worth trying a different USB lead and also make sure that the DIN plugs are seated properly.
I have had this problem and it is mostly caused by the din plug (round one) not seating correctly. You can replace this cable or you can get an exacto knife and cut the small plastic surround at the end of the plug before the metal section starts. This allows the plug to fit into the socket tighter.. Never had the problem again... Hope this helps
I have been following up all your suggestions. I have been in contact with
Theo at Gama who is giving me prompt and considered advice.
It looks like my problem is a hardware fault in the camera rather than
software. So I will follow this up with Theo.
Thanks all for your help. Eventually I may return to this thread with a
good result!
It looks like your solution about trimming some plastic from the 4 pin
control cable into the camera solved the problem. The camera now
works normally when the plug is pushed further into the socket.
The cable checks out fine so I think that the problem has occurred when the plug has moved in the camera socket during cable shifting during imaging so that the pins on the socket are probably splayed a bit not permitting good contact. Pushing the plug in further allows mating with a bit of unsplayed socket.
This is a lesson learned, so I think I will devise a way of firmly attaching
the cables to the camera with say a metal bracket so that the cables
are held firmly and not allowed to wiggle during imaging. (I did think about replacing the camera socket but this would be hard the way the socket
is imbedded in the camera.)
