Posting my first public patch - any/all feedback welcome!
What it does is: remote shutter control for Panasonic PT-d series projectors,
but could probably be easily adapted to other beamers with
RS232 control. Could also be used to control any other binary function (lamp on/off etc…)
However I did look into the ethernet option briefly - theres either some kind of web browser control (which prob isn’t fast enough to do a show) but also this new thing called PJLink. Only a few projectors have it now (mostly Panasonic?) but it could become a widespread standard.
It sends commands over TCP, with a call/response structure fairly similar to RS232. However it seems like there is only a limited amount of commands you can send - including a video mute command.
As I didn’t have the units until I got into the space I didn’t know whether that would just blank the screen digitally or activate the shutter, so I decided to go with RS232 instead.
It also doesn’t seem like there is the capability of adjusting focus or zoom - which is what I want to do next.
