First time poster first time reader. I was refered from a member at racketboy forums as there is a member of the name of Fudoh who is the guru at this stuff... so please help
Anyway, so my problem goes...
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?
Sounds about right.... just repost (without quoting) in the main thread.... The XRGB-3 has many adjustments and is intended for someone who likes to tweak settings! List each "issue" separately (give each a line break).
And as always, do not connect SCART cables to the front input!!!
I would simplify the connection. On the XRGB you don't need any voltage signals, neither for Pin 8 nor Pin 16. There are Scart ciruits out there which connect the sync signal to the voltage lines. Just throw them all out. Just R/G/B, Composite Video or Sync, Audio and one or two Ground lines.
Overall it sounds like a cable issue, not a XRGB settings mismatch.
What? nooooo but I just finished making that damn cable...
he meant japanese RGB 21-pin vs. Euro Scart. Of course you can use the front Scart input, you just must not ever connect a Euro Scart cable to it, otherwise you're likely to blow your XRGB.
I was reading the japanese manual on the train last night, and I was looking at the pinout... and I could see that pin 11 and 16 iirc was not used... (for AV select) do I need to still make sure I have 5v and 1v on those pins or leave them completly?
Also for the above consoles, do I need to add the resistors and caps? I would have thought if I add resistors it would make the signal darker wouldn't it? or is it needed to get the right impedance or something like that?
As said: On the XRGB you don't need any voltage signals. You can cut Pin 8 and 16 from any Euro Scart cable you use (with an adapter) and Pin 11 and 16 from any japanese RGB21 cable you use.
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.
