Hi,

Thanks. I got the iKon camera working with the latest ADAndor 2-8 release, using SDK version 2.102 (the version packaged with ADAndor). 

The initial problem I had with the old SDK was that the udev rules didn’t work on RHEL7, so the USB device had the wrong permissions. So I updated to the latest SDK from Andor (2.103). That fixed the udev rules, but the older SDK libraries in ADAndor generated a seg fault. Then I updated to ADAndor 2-8, and used SDK 2.102, and that seems to work fine. 

I also tried manually updating the older ADAndor with the newer SDK libraries from 2.103, but there seemed to be an incompatibility with the older shamrock libraries also in ADAndor. Presumably the shamrock libraries are distributed via a different SDK from Andor?

I haven’t seen any issues restarting the IOC yet. 

I’ll do more testing, and also update ADCore to 3.X, since I’m using an older 2-6 version. 

Cheers,
Matt

The Andor SDK would leave behind a shm object that would not get removed by the SDK in that case which resulted in subsequent IOC restarts to fail to detect the camera (until Linux OS would be rebooted). I did find a way to solve the issue by removing the offending lingering shm object using ipcrm tool, prior to starting on IOC.
