Jprada has successfully modified SKY PLUS Pace Digibox set top box with the SDI Mod. Kit.

These are the pin assignments.

Data wires and clock wire are soldered on the decoder board.

The SDI Converter DIY Kit is mounted on the rear panel.

Please note that there is no need for the capacitor but it is recommended to twist CLK and GND together. Then both the standard and the SDI output work perfectly.

Thanks for Jprada's contribution.
