Mark,
However, there may be a quick solution to Brian's problem, since I suspect it is related to areaDetector?
...
It is related to AD and this "trick" is where I got burned to begin with
:) In my case (Perkin Elmer), I have an areaDetector device driver that
talks to a family of detectors: a 1 megapixel and a 4 megapixel panel
in this case. The vendor API is the same for each. I naively set the
mbbo for the detector timings to the values for the 1 megapixel detector
I've been developing with by setting the values in the detector template
file as you suggest. When we started using the 4 megapizel panel, the
frame rates were all wrong because it uses different timings.
I can create a different template file for each panel but the valid
timing values can be retrieved from the detector at run time. It would
be better to be able to set them somehow.
It looks like these panels may support a more arbitrary selection of
exposure timings and that the 8 preset timings provided by the vendor
API are more of a convenience. If this turns out to be true, I'll drop
the mbbo and use a more generic record type for this case, but I know of
other detectors where this may be an issue as well.
