I have a BENQ projector that I need to control in software. It supports the Crestron protocol. I'm working in C#.
Is the Crestron protocol known?
Is there an API or SDK?
Are there samples anywhere for control a projector?
After many days of digging and arguing with BENQ technical support the only conclusion is that the protocol is propriety and they will not disclose it. New firmware for this projector support PJLINK so I am dropping this line of development.
