Cannot add device

The last two source commands worked. 
​​​​​​It did take two HDMI2 commands for it to change, but only one HDMI1 command.

Ok, I found on the Interwebs that the projector needs a super secret handshake. You must first send a PJREQ and if it gives you permission then you can send a real command. The driver is now sending the handshake sequence.

Thank you Dave. 
The power off command works perfectly as well. 

While you're in making changes can you add the password that's required on all of the newer JVC projectors? Pretty please

Saw someone logged in and did some more work with the JVC driver and transferred some files.
May I ask what you were up to ? 

I was refining the driver to finish making changes.

The driver has been updated and it will now track power state. It will also support sending a password if the projector requires it. The AddProjector command now supports an optional password parameter. If you projector does not need a password leave it blank.

Finally the command builder overlay exposes a side panel so that you can directly test command and control of the projector.
