What is Class 1 and Class 2?

Projectors support different versions of the protocol.  Our driver supports both Class 1 and Class 2.  Class 2 is an expansion of the Class 1 PJLink protocol which provides the following additional functionality.

  • Serial Number

Can you give us some examples of how we could use this driver?

  • IP Control means that you can eliminate IR buds from your projector and also make ultra long cable runs unlike RS232.
  • Get two way feedback on important information such as lamp hours, filter usage time and various projector errors.  Your clients can now know when projector has a fault or requires a replacement filter / lamp using the included variables.
  • If the client manually turns on the projector or uses the original remote our driver will automatically switch to the source on that input.

I want to try this driver out before buying it?
All Chowmain drivers for ELAN come with a 7 day trial.  This is activated once you add the driver to the project.  No additional steps are necessary.
