This is a collection of scripts designed to control analog and digital video switches via their RS-232 interfaces. Additional devices are controled through IR via lirc.

• Raspberry Pi or other linux based system
• Gearmo 4port RS232 USB to Serial Adapter
• USB Infrared Toy
• Panasonic TC-P65VT30
• Extron Crosspoint 450 Plus 128
• Monoprice 4x4 Matrix
• Monoprice 8x1 Switch
• OSSC

Cables going into the Extron Crosspoint are either system specific HD Retrovision (blue) or Nintendo Wii/WiiU (green) cables with a 6ft HD Retrovision Male-to-Female extension, terminated into 75ohm RCA to BNC. Audio cables are terminated into Phoenix to RCA Adapter

The hardware API is built upon flask to create a simple interface with pyserial to send commands to the TV, HDMI Switch, HDMI Matrix, and Extron Crosspoint

To control the OSSC LIRC is used with the USB IR Toy to send IR remote commands.

Note: The Monoprice 4x4 matrix seems to be a clone of or cloned by the Lindy 38152. The command codes for the Lindy seem to work correctly with the Monoprice unit as there are no codes on the Monoprice website.

HDMI Switch Codes

HDMI Matrix Command Codes

Crosspoint 450 Codes

Panasonic Codes

The UI was written using Vue with the Vueitfy material framework. Logic was written in TypeScript.

Images of the various systems come from the great work done by Evan Amos whose work can be found at https://commons.wikimedia.org/wiki/User:Evan-Amos

Below are some views of the app running in Firefox on an Android phone.

To switch to a source simply tap the system you want from the list.

Sources that case be upscaled will have a toggle when either can be selected.

Displays like a CRT will only allow the selection of analog sources

While a capture card will allow only digital sources which include upscaled analog sources

Different sources (TV, CRT, Capture) can all be selected from the side menu

• No authentication. Not designed for public IPs.
• Hard coded control logic. To work around this an abstraction for a display, switch, matrix, and upscaler would be needed.
• No querying of control hardware state for dynamic UI updates. The 8x1 switch does not have the ability to query which channel is active or which are even powered on.

• OSSC profile selection per system
• Include more system icon variations from Evan's work
• TV specific functions (Turn on/off, mute, vol up/down, etc)
