Library to control BenQ projectors.

Python library to control BenQ projectors

Python library to control BenQ projectors over the serial interface.

BenQ projectors and flat pannels with a serial port can support one of three protocols. This plugin supports projectors which are of the L, P, T, W and X series but probably also others.

Protocol

This are the protocol details:

2400 baud 8N1

<CR>*<key>=<value>#<CR>

Where <CR> is a Carriage Return

Examples:
Power on : <CR>*pow=on#<CR>
Power off : <CR>*pow=off#<CR>
Source HDMI: <CR>*sour=hdmi#<CR>

The same commands should work over a network connection, but I don't own such projector and have not implemented any network functionality. Contact me if you have a network connected BenQ projector and like this to work.

PJLink

This library does not implement the PJLink protocol, but a proparitary BenQ protocol instead. The PJLink protocol is covered by other libraries.

Supported projectors

Known to work:

• W1110
• X3000i

Not tested but use te same protocol according to the documentation:
Others in the L, P, T, W and X Series

Not supported:

• RP552
• RP552H
• RP840G
• RP653
• RP703
• RP750
• RP750K
• RP652
• RP702
• RP790S
• RP705H

Please let me know if your projectors is also supported by this plugin so I can improve the overview of supported devices.

Installation

You can install the Python BenQ projector library using the Python package manager PIP:
pip3 install benqprojector

benqprojector CLI

You can use the Python BenQ projector library directly from the command line to turn on and off your projector using the following syntax:

Status of the projector: python3 -m benqprojector <serial port> <baud> status
Turn on the projector: python3 -m benqprojector <serial port> <baud> on
Turn off the projector: python3 -m benqprojector <serial port> <baud> off

Detecting your projector capabilities

The benqprojector CLI can detect the commands, sources and modes your projector supports. If you like to have your projector fully supported by this Python library please run this command and create an issue on Github with the output attached.

To examine your projector capabilities: python3 -m benqprojector <serial port> <baud> examine

Your projector needs to be on to be able to detact all your projector capabilities.
