Mitsubishi XC3315C pinouts

[Kiriko]

I would like to apologize if this is in the wrong place.  Please move it to it's proper location if it is in the wrong forum.

A little while back, I asked help for the pinouts for the 15 pin RGB on the Mitsubishi XC3315C since no information could be found on it anywhere on the net.  Well, I recently found out what they are and I'd thought I'd post them here, in case anyone else here has one of these monitors and don't know the pinouts.  The pinouts were given to me by a friend of mine (sonofx51), so all credit so go to him and huge thanks also goes out to Matthew Ross.  The pins were verified using a PlayStation 2 and Saturn with a sync separator.  Dreamcast doesn't work due to the sync separator.  So as long as you don't use one, it will work fine.

pin 1 = RED
pin 2 = GREEN
pin 3 = BLUE
pin 4 = H sync or composite sync
pin 5 = V sync
pin 9-11  = GROUND

I'm kinda confused about the sync seperator.  PS needs one, but the DC + Saturn both output composite sync as well as composite video.  If you're using an LM1881 to seperate the sync  you can feed it both signals and it will output c-sync...

The sync separator was mainly there for the PlayStation.  It will not work WITHOUT one.  The Dreamcast is fussy with it and won't work WITH one.  And the Saturn works with or without a sync separator it seems.

The dreamcast does have two RGB modes, you might try the other and see if that helps.

Interesting that the PS2 wouldn't work on the 15 pin connector without a sync separator, since I could feed composite video with RGB into the BNCs and it worked fine (when my xc3315c was working properly anyway ).  Now,  would your friend happen to have the service manual so I could fix mine?  I've had no luck finding it.

Do you have more information on this? When you say two RGB modes, do you mean two different 15KHz RGB broadcasts? (I ask because I am guessing when you say this, you don't mean RGB vs. VGA = two RGB modes?) If there is a way to enable a different 15KHz RGB mode, it would be good to know: when I first started playing around with making my own cables I toyed with the Dreamcast for RGB and found several games that didn't work in RGB, but would work in VGA, would work in RGB but not in VGA, or would not work in VGA or RGB, and still others that would work in one of the three modes (VGA, RGB, or Composite/S-video) but if switched quickly to the other desired mode (VGA or RGB) they would then work. I have been planning for some time now to get an all-SCART solution by way of the cheaper switchboxes (with an LM-1881 & PC Engine amp in the switchbox) so I can avoid having to constantly cut up new cables when I get them (never got around to finishing the box, lack of time) but if there are two RGB modes for the DC would I need to add a switch to the DC cable?

Edit: duh, did you perhaps mean an RGB via Composite video and another via Composite sync? I'm wondering why that would make a difference, does it? Since K couldn't get his set to work through the sync...

Pin six, when grounded, produces one RGB mode.  Pin seven produces another, and both pins = VGA.

So I've been told, I've never gone through the effort of finding out what the difference is.

No sorry, nobody I know has the manual for this thing.  If I did, I wouldn't have to pull out my hair searching for the pinouts to the 15 pins on it.  Good luck in finding the manual.  If you ever do, could you please, please pdf it.

The saturn sync output will not work in all cases,so a sync seperator may still be required.Also I thought that pin 7 was a rgb/composite switch and pin 6 was a 15.75/31.5 horizontal scanrate switch.I can't see the need for two 15.75 khz rgb modes.
