BMSDI.Tally

This BMSDI.Tally converter extracts tally information that is embedded in the return SDI signal of a Blackmagic design ATEM videoswitcher, and outputs it to an external tallylight

The interface has a built-in tally LED and a 3.5mm connector for tally output. The tally is dimmable and the tally number is selected with a rotary switch.

The converter is based on Blackmagic 3G-SDI Arduino shield.
