Symptom:

Newer scout-GigE Cameras take longer to "connect / open / initialize" when used on older software.

Specifically, if you tried to run scout GigE Vision cameras with firmware version V4.x-x or greater, with software libraries using old GenICam versions, e.g. GenICam less than V2.x, you may experience long times for opening a camera.


Root Cause:

The reason for this behavior is that older GeniCam versions used a smaller xml file and a slower xml parser mechanism than the current GeniCam versions. So therefore an xml file describing features stored in a camera's firmware built to GeniCam v2.0 will take longer to parse on a host PC running software built to GeniCam v1.0. 


Solution:

scout-GigE cameras now include both an older and newer xml file. Users can then select the file that suites them. 


Notes:

  • Older xml files do not contain some newer features - ie: Sequencer, Color enhancement, etc. 
  • The longer delay should only occur on the very first connection by the PC to the camera. 
  • On subsequent connections, the PC loads a cached version of the xml from the Harddrive and thus performance improves. 
  • The customer can also update to the latest GeniCam version on the host PC by updating pylon.
