JPN White Saturn and 3rd Party RGB SCART Cable

[s8n]

hi again Saturn scene , i have 1 US Saturn with a 3rd Party RGB SCART Cable it works as it should.

I would like to get in the future a JPN White Saturn , will the 3rd Party RGB SCART Cable i already have work with it ?



any tips help

Yes.

I use a third party RGB SCART cable for my White JPN Saturn. It works flawlessly for me, except on my NTSC wide/large projection television when converted down to component video from RGB. (It keeps flickering and losing signal) Works with composite though.

But I have absolutely no problems at all on my CRTs.

Also, I live in Canada, where RGB SCART is non-existant, so it'll probably work on your TV regardless of what kind it is.

RGB scart should be fine bud

While there are differences between the US and EU Saturns SCART output, there's no difference between the NTSC Saturns, so it will work exactly the same way.

Yart, you may be able to cure that problem by using the Saturn's composite sync instead of sync on composite video, but finding a Saturn SCART cable wired this way is difficult.

hi guys its great to hear from you , the replies were insightful and friendly thank you all for that


i hope to hear from you again in future Threads

I'm pretty sure that this is because most third party RGB cables use the +9v dc signal for the scart rgb switch pin. That signal is only used in PAL machines, on NTSC ones it is the composite sync pin. This outputs around 3v normally, which is enough to switch to RGB. However the voltage varies as the console switches resolutions or even just by whats on the screen. If the voltage is too low, the SCART cable will switch back from RGB to composite. Since the voltage in the sync signal varies randomly, all sorts of crazy things can happen with the video.

This can be remedied by either using a cable that uses the +5v dc pin for the scart rgb select pin, or by modifying your saturn to output dc voltage instead of composite sync.

Possible, but I'd have thought a converter like that only supported RGB and not composite, and so would ignore the signal pins anyway.

Eep don't do that! The pure composite sync is needed in some instances!

Scart can carry a lot of different signals, so the selection voltage must be supported. If that converter only worked with RGB only, it wouldn't work with a ton of equipment that uses a scart connector but only with composite out, and that would lead to a lot of customer complaints.

In what instances? Every single SCART cable I saw, including the official japanese RGB21, used the composite signal to split the sync info instead of using the pure composite sync.
In fact you can't even use the pure csync signal should you mod your own cable, because the voltage is too high for SCART standard.

The mod can be reversed anyway, and you need RGB output for more often than the pure csync.

Not really, lots of high end equipment ignores those pins and only supports RGB. The DVDO Edge and the XRGB3 video processors to name but two. SCART is a confusing standard anyway, people complain about that all the time but we're still stuck with it.

Pure sync is needed by some equipment (XRGB3 in certain circumstances) and it can also help on some TV's/15khz compatible monitors that don't handle the Saturn so well.

You absolutely can do this, I do and it works perfectly fine.

Just get one of Adaptorman's NTSC Saturn SCART leads from E-bay, no modification necessary then.

Well, it all depends on your equipment. On my end, the picture was jumping when using csync, and only stabilized after adding some resistance to reduce the voltage.
