Atik 383L+ Shutter question

[ogami]

I have got one question about shutter in this camera. Im just playing and testing with new camera and one thing seems strange to me. Even if i set shortest possible exposure (0.2), shutter stays open for something like 4-5 seconds. even the shortest exposure gets oversaturated in the dim lit room. This is my first camera with mechanical shutter and i dont know if its how it suppose to work, but it seems strange to me.

Thanks for your help.

i made some videos today to better explain shutter problem.

first video shows strange shutter movement after connecting the camera to control program (MaxIm DL, ArtemisCCD).

second video shows how long shutter stays open (6s). this is 1s exposure in MaxIm DL.

i tested almost everything ... tried 2 diferent PCs, 3 USB cables, 3 programs (MaxIm DL, ArtemisCCD, SGPro), 2 types of power sources, Ascom and ArtemisHSC drivers, but problem still remains.

Hi,

When the camera is connected the shutter always clicks twice to say hello, absolutely normal 
On the other side the 1 second exposure behavior is kind of starnge... What binning did you use?
Does this behavior change if you use different binning?

I tried bin1x1 and bin2x2 with same result. Today i discussed it via mail with Vince from Atik. Camera will be sent soon back to factory by my local dealer for further investigation.
