Extron Scart Adapter projects

Extron Input Adapter

Extron-Input README

This board should plug into an extron crosspoint input, and has the following features:

1. Female Scart input
2. JST header to Phoenix adapter (cheap)
3. Sense header to determine if connected cable is "active"
4. Selectable LM1881 Sync Stripper for sync on composite video / sync on luma

Extron Output Adapter

Extron-Output README

This board should plug into an extron crosspoint output, and has the following features:

1. Female Scart output
2. JST header to Phoenix adapter (cheap)
3. Selectable termination resistor for 75 ohm or TTL level sync output

Extron SCART Autoswitcher

Autoswitcher README

This board plugs into the serial port on an Extron crosspoint, and works together with the input cards to determine which input has be most-recently powered on, and automatically switches to that input.

Simple Scart Adapter (DEPRECATED)

This board was my first attempt, and it turned out to not be workable. I'm leaving it for posterity, but you shouldn't use it. The spacing is way off for a Crosspoint. I based the measurements on an Extron System 5CR Plus, which has narrower spacing between BNC connectors.

This is a work-in-progress as well, as I believe I'm missing the attribution on the boards. My intent is to license them properly.
