calling XRGB-3 experts

[brendanraymond]

Hi

So I was super excited when my brand spankers XRGB-3 came in the mail yesterday.

I hooked up my custom universal RGB cable to my MD2 and was a little disapointed.

My connections should be fine... for AV select it is tied to 5v and the other i think pin 16 is also tied to 5v... but it should be 1v right??? so do I need a resistor for that one?

Anyway... I don't have the 220uF caps on the RGB lines yet... because I am using the same cable for the saturn too. Anyway, I set the XRGB to 75ohm and I'm getting the RGB signal I think... but some of the sprites or shall I say contrasting colours leave like a shadow that stretches out over the right hand side.

And also the colour is very dark...

And then I tried to connect up my sega saturn... and i just can't get it to work... it keeps jumping between 15kHz, 45kHz and nothing... I can't even adjust the settings when it does that. I did manage to see the red signal come on screen once but I don't know how I did it

Do these sound like typical noob operating errors or is there something very wrong going on here?

Thanks in advance!

Unfortunately I'm not much of an expert when it comes to the RGB connector on the XRGB; I tried using a JP SFC cable but found I was getting a very dark picture and switched back to s-video through the XRGB.

I would post over at http://shmups.system11.org

There is a user there that goes by the name, Fudoh. He will be able to help you if anyone can.

Good luck

I worked out what the problem is!

The root of all shit RGB comes from the Sync line. I changed over to composite for sync signal and all I can say is it looks beautiful!!!

Also I have a broken connection on my green and blue signal cables on my sega saturn... damn.

I scoped the Sync line and i would say 80% of the time it was giving a signal above 5v... where the comoposite was around 1v ish. That doesn't seem right to me.

Whats more strange is that I get a shitty picture with my MD2 using sync, but I actualy don't get any picture from using sync on the saturn... pergaps its broken? changing 60/50Hz doesn't make any difference.
