Hi Mark and Tom,

I tried what you suggested and after a little bit of fiddling around it
worked. I was able to see the images with the ImageJ viewer at almost
the trigger rate of 50Hz.

What puzzled me was that although I had 16bpp imagej was only displaying
8bpp and the values were wrapped around several times. Hence I tried to
use the edl screens to switch from 16bpp to 8pp and I completely messed
up the configuration of the camera. I got a lot of uknown pixel value
errors. After checking that the ioc is working fine with another camera
I tried switching of both cameras. Luckily the wrong configured one came
back in a sane state. I have no idea what went wrong, since I tried
changing the data type, the bpp, the pixel format all without any success.

The next test was now to fire up imagej on my mac (with osx 10.9). I
installed the plugin (ImageJ64 doesn't work with the plugin) and
ImageJ32 is able to load and to connect to the camera. However, I get
only "20/11/13 22:28:29.77: UpdateImage got exception: pendIO timed out"
errors.

Besides this I'm wondering how I can now include a few other plugins
like NDStats and NDOverlay.

But anyway, thanks for the fast and well directed help.

Cheers,

Flo

Have you run the aravisGigEApp/src/makeDbAndEdl.py script to make a database and screen for your particular camera? If so, then you need to point the substitution file at the database template that this script created.
