Scart switching with 12V
Scart switching with 12V
The only thing using 12V on the H4 is the scart switching. So does anyone know, or can try a scart cable, to see if it still switches with 5V instead of 12V ?

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~

Re: Scart switching with 12V
Most Atari ST SCART cables have the 12V going to PIN 8 on SCART. From the SCART Wiki:
Pin 8, the switch signal pin, carries a DC voltage from the source that indicates the type of video present.
0 V–2 V means no signal, or internal bypass
4.5 V–7 V (nominal 6 V) means a widescreen (16:9) signal
9.5 V–12 V (nominal 12 V) means a normal (4:3) signal
