> Could you please elaborate "Are you sure it is also set OK on the caQtDM process?" As to what variable to look for in this?

Just before you launch caQtDM, either manually or in a script, execute this command:

printenv EPIC_CA_MAX_ARRAY_BYTES

I have not used Ubuntu 20, but I have built medm on Ubuntu 18. areaDetector comes with screens for medm, edm, caQtDM, CSS/Boy and CSS/Phoebus. Most of these are autoconverted from medm screens.

Thanks Mark for quick response.

Could you please elaborate "Are you sure it is also set OK on the caQtDM process?" As to what variable to look for in this?

Moreover, a detailed guide for installation and make it working using ADAravis and ADGenICam would be really helpful. Could you please provide a link?

Another thing, is it advisable to install MEDM on Ubuntu 20.04 as lots of x11 packages have gotten obsolete for this version. We are working on EPICS7.

Thanks again

Hi Asjish,

Since ImageJ works it looks like EPICS_CA_MAX_ARRAY_BYTES must be set OK on the IOC and on the ImageJ process. Are you sure it is also set OK on the caQtDM process?

It is not related to this problem, but I would suggest you consider migrating from aravisGigE to ADAravis (or ADSpinnaker). arabisGigE is no longer actively supported.

Subject: caQtDM caCamera widget not rendering images

Hello,

I am trying to add a new camera (FLIR's Blackfly S) into areaDetector (aravisGigE) with GUI on caQtDM. Earlier I had the attached GUI completely working with both ImageJ and caCamera widget able to render the images. But now after changes in my camera processor board (new serial ID etc.), all things except for caCamera are working. X-Y profiles are working but caCamera is unable to render any image.

I have made no changes in the settings just replaced the earlier .edl and -feature.edl files (and also the .ui files) with new ones based on the xml config file of new camera.

Could you please help me here. I doubt on the caQtDm installation. Or anything else?

Thank you.
