The probem with the Monster emitter is that it must be connected to an electrical sync coming out of the projector or ith another cable with an IR beam receiver on its end must receive the IR beam flashes and convert thenm into electrical impulses. How does a DLP Link sync get transmitted from the projector? I assume its some sort of flashing light beam that is not IR. This means the Monster IR receiver cable cannot be used and there is no plug on the projector which puts out an electrical sync pulse. The guy from France would have to design a cable with a light receiver to receive the DLP Link flashes from the projector and convert them into pulses and get them into the Monster emitter.
The cable he designed for a Sony projector using IR but sending that IR to an external IR emitter is rather simple, a bunch of grounds, a voltage converter to take the 12 volts out of the Sony and convert it into the 5V needed to power the Monster emitter, and one wire from the projector carrying the sync and using the same ground as the emitter power from the projector. The cable can be simplified by using an external 5V supply and then you have only grounds going to the IR plug on the projector, one wire carrying the sync from the projector and going to the emitter, and the 5V positive going to the emitter. The projector here under discussion does not have a DLP Link output plug and one would have to hardwire inside the projector. No one is going to do that. Some genius is going to have to design a DLP Link cable with the right senor on its end to go into the emitter and external 5V power supply will be needed with the sensor ground being in parallel with power supply ground.
