Hi,
Can I turn on a lamp with GPIO/GPO?
I have Christie 2220 and Doremi DCP-2000 and DCP-2K4.
For example:
I want to press a Remote button and the lamp will go on.

One way is to set up "fire alarm" macros in the Doremi - these are special in that they will run without a playlist loaded: they don't have to have any fire alarm related function.
Trigger macros from server gpio (or a Jnior) that do whatever you want. I've done this to have a podium system start up the projector and set it for playing video from the podium in a multi-use auditorium where some users don't have booth access.

Raz: What/which lamp do you want to switch on remotely - projector, or external light?

Assuming you mean the projectors lamp, have a look in the documentation at the SCCI connector on the Christie [Wink]

Hi,

A NO push button across pins 2 and 9 will bring the lamp on.
A NO push button across pins 4 and 9 will shut the lamp off.
