Subject: AreaDetector ImageJ viewer problem

UNRESTRICTED / ILLIMITÉE

I'm trying to use the ImageJ viewer to stream images from an Andor CCD camera and not having much luck. The AreaDetector and its plugins all seem to be working correctly. ImageJ and the EPICS_AD_Viewer plugin seem to be correct and makes the link to the AreaDetector PVs. However whenever I acquire an image the following happens:

 

  -The ImageJ EPICS_AD_Viewer detects that there is an image and will (usually, if it's timed out from the previous acquire) open an image window. However the window is completely blank.

  -The ImageJ log prints the message "17/5/2017 19:26:41.332: UpdateImage got exception: pendIO timed out"

  -The following exception appears in the window where ImageJ was started:

I've tried various combinations with the same result, but I'm currently running ImageJ 1.51 on 64 bit Ubuntu 14.04, and the prebuilt AreaDetector-2-2. I've tried the viewer distributed as part of this prebuilt as well as downloading the latest viewer. EPICS base version is 3-14-12-3.

 

Thanks in advance for any help.
