I just bought a simple blaster & serial cable to better control my BenQ w1070
but when I went to add the projector.. I noticed that you only have commands for the BenQ w7000 projector.
I gave it a shot and it works for turning on/off of the projector but it does not have options for changing sources.
How do I go about programming a source button to change HDMI inputs in simple control with a projector that's being controlled thru a serial cable?
