Hello again! I am still trying to add projector control to my show (for over two years) and I can't seem to get ON OFF control to work. I even bought a new Hitachi short thro projector (was a dell before). It has an RS-232 control port. I purchased a null modem cable (USB from Pi) to the port on the Projector. I put a lead-in with ON the 60 second pause for warm up, then the sequence/show, the in lead-out the OFF for cool down.
No luck. If I MANUALLY turn on the projector, it starts the video, but wont shut down. I have added the projector settings on the Pi and included my entry in the Projector control via SSH and saved it.
Can you tell me what I missed or what I did wrong? I have looked over the hex codes several times and they look fine. (See attached)
