## Introduction

This Python library lets you control XY Screens and See Max projector screens and lifts over the
serial and RS-485 interface.

This Python library was first implemented for XY Screens. After I was informed that the See Max
devices use a very similar protocol support, for these devices has been added.

[XY Screens](https://www.xyscreen.com/) and See Max are OEM manufacturers of projector screens and
lifts. Their devices are sold around the world under various brand names.

## Features

- Position control: move the screen/lift to any position along the way
- Program device address on devices that support this
- Use multiple devices on the same RS-485 interface
- Synchronous and asynchronous methods
- Uses callbacks for asynchronous methods

### About position control

The XY Screens and See Max projector screens and lifts do not provide any positional feedback. The
state of the screen is thus always an assumed one. The screen position is calculated based on the
time the cover has moved and the configured up and down durations. This results in a potential
error margin. Every time the screen reaches its maximum up or down position the position any
potential error is reset. If the screen is controlled outside the library, for instance with the
remote control, the screen position and state will no longer represent the actual state.

## Hardware

Use a USB to RS-485 converter where position 5 of the RJ25 connector is connected to D+ and position
6 to D-.

I use this cheap USB RS-485 controller which you can find on
[Aliexpress](https://s.click.aliexpress.com/e/_c3kqcPN1) (affiliate link)

See the documentation of your specific projector screen or lift on how to wire yours correctly.

## Protocol

If your device follows the following protocol it is supported by this Python library:

2400 baud 8N1  
Up command  : `0xFF 0xXX 0xXX 0xXX 0xDD`  
Down command: `0xFF 0xXX 0xXX 0xXX 0xEE`  
Stop command: `0xFF 0xXX 0xXX 0xXX 0xCC`

Where `0xXX 0xXX 0xXX` is the three byte address of the device.

For XY Screens devices the default address is `0xAA 0xEE 0xEE`, while for See Max devices the
default address is `0xEE 0xEE 0xEE`.

## Supported projector screens and lifts

The following projector screen is known to work:

- iVisions Electro M Series

The following projector screens and lifts are not tested but use the same protocol according to the
documentation:

_XY Screens_:
- iVisions Electro L/XL/Pro/HD Series
- iVisions PL Series projector lift
- Elite Screens
- KIMEX
- DELUXX
- Telon

_See Max_:
- ScreenPro
- Monoprice
- Grandview
- Dragonfly
- WS Screens
- Cirrus Screens
- Lumien
- Celexon

Please let me know if your projector screen or projector lift works with this Python library so I
can improve the overview of supported projector screens and lifts.

## Installation

You can install the Python XY Screens library using the Python package manager pip:

`pip3 install xyscreens`

## `xyscreens` CLI

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> <address> down <duration>`  
Stop the screen: `python3 -m xyscreens <serial port> <address> stop`  
Move the screen up: `python3 -m xyscreens <serial port> <address> up <duration>`

Where `<address>` is the six character hexadecimal (three bytes) address of the device.
`<duration>` is the optional time in seconds to move the screen up or down, when given the process
will wait until the screen is up or down and show the progress.

For XY Screens devices the default address is `AAEEEE`, while for See Max devices the default
address is `EEEEEE`. If you have reprogrammed the device address use the appropriate address.

### Programming the device address

Some See Max projector screens and lifts which use the RS-485 interface seem to allow programming
the device address. This way multiple devices can be connected to the same RS-485 interface. Each
device should have a unique address.

`python3 -m xyscreens <serial port> <address> program`  

Where `<address>` is the three byte address to be programmed.

### Troubleshooting

You can add the `--debug` flag to any CLI command to get more details on what’s going on. Like so:

`python3 -m xyscreens <serial port> <address> down <duration> --debug`
