ASI2600 no exposures over 2 second

pogo

Hi all,

I just took delivery of a ASI2600 mc pro. I installed all the software and drivers and everything worked fine. It connects easily to my computer and is recognized by all software that I have. However if I take a test shot over 2 seconds, it will do so until about 0,2 seconds before the end and than the camera is disconnected and there is no exposure shown. I can reconnect and start over. It will work fine for everything under 2 seconds.

I have a second generation Surface pro that I have tested so far and I have not powered the cooler. I will try with the ASIAIR later today to see what happens with it.

Any idea what is going on?

Ok I posted this too soon. Problem solved. Appearantly my computer's usb does not output enough current. I connected the camera to a 12v powersource and that solved the problem. I'll just leave this post just in case somebody else runs into this problem.

Thanks,

Peter.

Hi Peter, thanks for your post, yes, ASI2600MC Pro needs 12V power supply to ensure its working.

Hi everybody,
It seems that ASI2600MC Pro needs 12Vdc for taking every long exposure over 2 sec. I tried on different computers (MS Surface Pro 4, Dell Latitude 5500, and a desktop computer) with different cables (both USB 2.0 and 3.0) and all tests lead to that same conclusion.
So it looks that it's not just a problem of the low power availability from USB port of the MS Surface Pro, but a need of the camera itself for doing long exposures instead.
Anyway I think that feature should be explained both in the user manual and in the specs web page, because it can limit functionality in some cases.
Regards, Danel

danelon 2600 533 6200 all required more current than standard USB3.0 specs
so it depends on the power supply of the USB host
there is such a description in our web page and user manual

Ce n'est pas forcement un problème de puissance en 5V du port USB 3. Si on utilise un cordon USB 3 en Y pour chercher le 5V sur un autre port USB en parallèle, ou si on alimente en 5V le cordon Y par une alimentation de laboratoire ou un petit power bank c'est le même problème. Au début ma 2600 fonctionnait au delà de 4 secondes très bien sans être branchée en 12V, mais maintenant il lui faut obligatoirement le 12V pour une acquisition supérieure à 4s. C'est un problème interne à la caméra sur lequel ZWO devrait se pencher.

Is this true of the 2600MM too? Will the 2600MM work with the ASIAir Pro?
