DMK 21 problem!!!!!

[Glasspusher]

Last night, at long last, I got to try out my new DMK 21. Seeing was far from ideal but I made a capture of Jupiter, which appeared to be OK. After this first capture every attempt I made at using the camera produced the error message, 'device is in live mode, but does not seem to be delivering images'. I checked connections and even reinstalled the software, still get the same error message.

Can anybody please help me with this?

Thanks in advance. #

I had that for a bit, drove me nuts...

It should work Ok if you lower the frame rate to 30FPS.

But on the back of my laptop, I have two identical USB ports. The DMK works fine in one but not in the other.

So try moving to a different USB port.

Thanks for those suggestions Ant, gave them a go but unfortunately the problem persists. I am beginning to fear the worst!

Are you sure one is not running, but minimised. Check the task bar just to make sure.

It's a shot in the dark, but hey, you have to try.

Have has this problem with my DMK, a reboot and a (rather unscientific) wiggle of the cables sorted it out. Have you checked/ replaced the cables John?

I have had it as well .... sometimes if the exposure has gone to a few seconds it was givign it...

[GazOC]

Yep, PB thats happened to me as well.

I spoke to the people that sold me the camera this morning, they suggested I test the camera on a desktop machine as there might be power issues with the laptop. The camera seemed to work OK on the desktop, perhaps there is a power issue with the laptop usb ports? Seems strange as the camera has actually worked OK with the laptop, but only for enough time to capture one sequence of Jupiter! Thanks to everyone who has chipped in, your thoughts appreciated, keep 'em coming.

Not a great ad for the DMK 21 ...

John,

Would one of those "Y" USB leads help John? The ones that have 2 plugs into the laptop and one output to the device? I think the second plug is just used to supply an extra 5v to the device....I think!!!

I suggest you bite the bullet and get a powered USB hub.

PS I have a USB drive that has a lead that Gaz has described. Only plug in one lead with desktop but need two with laptop.

What happens if you lower the frame rate right down? 3.75 FPS?

Which software are you using? Download PHD guiding and see if it runs OK with that.

Have you tried a different lead?

Join this forum The Imaging Source Community and post up a thread with ALL the details.

Thanks guys, some good ideas, I want to avoid using mains if possible so this might rule out a powered hub. Like the idea of the 'Y' lead, I will look into it. Thanks for the link to the imaging source forum I have made a post there.
