Python library to control XY Screens projector screens and projector lifts.
Python library to control XY Screens projector screens and projector lifts over the RS-485 interface.
XY Screens is an OEM manufacturer of projector screens and projector lifts.
I use a cheap USB RS-485 controler from eBay to talk to the projector screen where position 5 of the RJ25 connector is connected to D+ and position 6 to the D-.

You can install the Python XY Screens library using the Python package manager
pip3 install xyscreens
You can use the Python XY Screens library directly from the command line to move your screen up or down or to stop the screen using the following syntax:
Move the screen down:
python3 -m xyscreens <serial port> down
Stop the screen:
python3 -m xyscreens <serial port> stop
Move the screen up:
python3 -m xyscreens <serial port> up
If you add the arguments
--wait <time> to the down and up commands where
<time> is the time in seconds to move the screen down, respectively up, the
process will wait till the screen is down/up and show the progress.
