MEDM

  • Based on Motif.
  • Extensively used in all hall in Jefferson Lab.
  • Well understood by the Hall D online group.
  • Easy to set up and easy to use.
  • Limited functionality.
  • This is an old technology, and it would be desirable to not used as the main display manager for Hall D control systems. It might be useful for doing quick studies due to its ease of use.


EDM

  • Current display management in accelerator.
  • Requires Motif or equivalent.
  • Improvement over MEDM, enhanced functionality.
  • Somewhat more difficult to setup than MEDM.
  • There were issues raised by people from cryo group regarding how fast a screen loads when there are too many widgets on the screen.
  • Old technology. The only reason this can be considered as an option is if accelerator division decides to use this in the 12 GeV era.
