I did notice your error on the initial code and just followed your example of using the "$" as a hex place holder. For some reason, the projector just isnt listening to the input codes. All my input codes look just like the ones you just replied with.
Customer just purchased a Dell S718QL laser projector. I would like to request a driver be made in order to operate his new projector with his Control4 system. Attached is the RS232 protocol.
