ASI2600MC DUO exposure issue

dciobota

So, just got my duo and testing illumination of the asi220 guide chip with my asiair pro. So I set the 220 as my main camera, went to preview mode and tried to take an exposure at gain 0 0.05sec (pointed at the sky). I get exposure failure. I had also tried an autorun of 1 flat, same gain, autoexposure and got the same error.

Switched to video mode and I get a preview at gain 0 and 50ms.

Switch the 220 as the guide camera, start the view refresh and that works.

So, what gives with the preview and autorun exposure modes? Why do I get exposure failed? Is the guidecam broken in some way?

Oh the asiair version is 2.1.

Also, the main camera works just fine in preview mode, autorun, etc.

dciobota Can you submit the log in the ASIAIR app and test the camera in our software-ASIStudio?
Also use different USB cables and ports to try, do not use any hub, thanks.

So, to clarify.

I am using an asiair pro. It will be difficult to test the duo on a PC.

The main camera works fine. As a matter of fact I ran it for the first time all night last night with no issues. It shoots and downloads images with no problem.

The guide camera works just fine exposing as a guidecam through the asiair version of PhD. It guided fine all night last night with occasional star lost due to dim stars through my narrowband filter.

The camera is attached directly to the asiair through a single USB3 cable. I have an eaf attached to the camera hub as well as a the original USB stick from my old asi2600mc pro. The 12v is supplied from the asiair which is supplied from the am5 which in turn is supplied from a 5a power supply set to 13.8v.

This setup has worked with the old asi2600mc for several years now. Are you saying this won't work with the new camera? It seemed to work fine last night.

I just wanted to know if the guide camera can be used as a main camera to take images in preview, autorun and plan modes.

Also another point. I was able to switch the guide camera to be the main camera last night to run the focus routine, which also worked fine. I was able to find focus the guide chip that way. It's just the preview and autorun modes seem to give that error, so it seems more of a software than hardware issue to me.

So a final update. Turns out it was a cable after all. Used one of the new cables that came with the camera and everything worked just fine. I guess that 4 year old cable was getting a bit tired. Weird though that it worked just fine all night last night downloading main camera images and guiding.

So everything is fine now. Thank you for all the suggestions for debugging this.
