SharpCap Forums

I have a ZWO ASI 120 MC connected to a Windows 10 HP laptop with Sharpcap. In the viewing screen in Sharpcap, there are no changes to be seen as I change the Gain, Exposure or Brightness sliders. Even when I point the camera to a ceiling lamp and have an exposure in seconds ( not milliseconds) , the dark screen dosent change.
The log file is attached.

Do I need to change any settings?

Many thanks for your help.

Best regards

Hi,

From the log it looks as though all the frames from the camera are being dropped perhaps because of poor communication between the camera and the computer. I would suggest that you look at the post giving hints on troubleshooting USB issues which you can find linked at the top of the 'bug reports' forum.

Cheers, Robin

Which ASI120MC model is it - USB2 or USB3? Also are you connecting to a USB2 or USB3 port on the computer?

Thanks for the responses.
The camera has a usb 2 and is connected to a usb 2 port on the computer.

That helps. I have the same camera. Can you capture a single image and post the camera capture settings file and a screen shot of SharpCap just after the capture.

One other thing, have you downloaded the drivers from the ZWO site?

If it's the USB 2.0 version it is known to have problems that were fixed with the 120mm/mc-S version. Last time I read up on it I don't think a fix was found.

You could go to the ZWO website and download their firmware installer and get the lastest firmware on it.

This thread is a little out of date. ZWO stopped making this camera about a year or two ago so this thread was somewhat current when they stopped making it. Not sure if it ever got fixed.
