Re: Synchronization problem Princeton Instruments PIXIS1024B
A related issue (dropped frames) has been observed with the PVCAM software used by Photometrics camera which also supports Princeton Instruments cameras. The problem occurred during acquisition of 64x64 images every 4ms. A software engineer at Photometrics is trying to fix this problem.
If the exposure time is on the order of 1 ms, I see there may be 'race condition' in the logic waiting for the completion of the exposure. There is a means of working around this problem.
What exposure time are you trying to use?

I'm having a similar problem to one that Kate Phelps asked about on
12/28/09. I can't seem to synchronize my camera (Princeton Instruments
PIXIS1024B) with either the dia pillar illuminator shutter (Sutter
Lambda SC SmartShutter plugged into COM1) or the Ti Intensillight
(plugged into COM5 on the computer).
Scope: Ti Eclipse
OS: Windows XP
When I use the micromanager main screen to snap a picture, if I set the
Exposure time (Under Camera) too short with AutoShutter on, then the
shutter opens and closes before the camera shutter opens and closes and
I don't get anything.
Did you figure out how to fix Kate's problem? Perhaps something similar
would work for me.
The problem seems to be that the camera and the shutters aren't talking.
There is an "EXT SYNC" plug on the back of the camera to plug into a
TLL slot (there is one on the SmartShutter). So perhaps this isn't a
However, if other cameras just use a USB connection to the computer and
can be synchronized through software with shutters, then I would expect
this camera could be too.
