PJLink is a new unified standard designed to make communication interfaces and communication protocols that have been different from one projector manufacturer to another uniform and common.  Several Japanese manufacturers have adopted the PJLink standard for their projectors.  With this PJLink driver for ELAN you can control multiple projectors via IP with 2 way feedback.  Supported manufacturers include (but not limited to) BenQ, Mitsubishi Electric, InFocus, NEC, Casio, Canon, Sharp, Sky, Seiko Epson, Sony, Panasonic, Hitachi and Ricoh.

Note that this is not a definitive list.

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
  • Software Version
  • Internal Resolution
  • Recommended Resolution
  • Replacement Lamp Model
  • Replacement Filter Model
  • Filter Usage Time

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.

Do you offer showroom discounts?
