So I did some further testing.
By 1 '' between each capture, well I still had the window with the cross. Then after further testing, I did not have the window with the cross.
Then throwing example 2 images, only one was displayed with the cross ever.
Then in my last essay, I no longer trigger my camera via Astroart.
I am connected, I have chosen 600D, I have the same path C / user ...... in utility. My cable is fed since I can launch from triggering Utility.
I see my 600D in Astroart is unstable.
I persevere. I clicked on the little clock on the bottom (photo) and I tried again to "start". The ApN is triggered but only taken while 2 were scheduled.
Then he came out quite bizzare image with red - green - blue - basic colors of the sensor (photo) and I waited a few seconds and I raised a trigger. 2 images this time there (always with the cross) were displayed but not trigger my camera this time.
Note that I've also tried with another cable, I changed ports several times (I have 3) I even uninstalled the drivers ascom (in Astroart) to drive the PLB camera Inova homing thinking I had compatibility problems with the drivers, but nothing worked. I did not have all these problems in my shots with the 350D.
Also, I was using windows vista and 350D while there, it's Windows 8.1 and 600D so nothing has crossed since I took the download Astroart diskette to reinstall in windows 8.1.
Well now, I think I have said everything.
