Title: Confused Over A/v Output Diagrams
Post by: ferrari_rulz_02 on August 06, 2005, 05:05:00 PM

hello there guys.

i got hold of two digrams that allow you to get heaps of different a.v outputs from teh xbox.

i am planning to, on my new case, have a lot of the different a/v outputs, so that i can run it in different modes, depending on where the xbox is. im goign to have three buttons at teh back of my new xbox case that im makign, so i can choose what a/v mode the xbox is in.

the outputs that i want to get are:
-Componet video
-D-Sub Video
-Composite Video
-Sterio Sound (the two rca ones, like the standard av kit)
-Coaxial digital sound

i ripped a board out of my old dvd player, and it has the connections for these.

so anyway, i got hold of these two diagrams:




so is it just me, or are the two diagrams conflicting?

cheers

I used the top diagrams to mod my Xbox. I have all the outputs except vga. I followed it exactly ands every thing works. It was really hard to solder all of them though.

I believe you do but I am not positive. The VGA is the only output I didn't do.

Yeah, I installed three toggle switches in the back of my case.

Yes, it is possible.  I have done this to my xbox and it works very well.  The top diagram worked for me.

so if i am just interste in advanced a/v and hdtv a/v then i can just follow the bottom diagram? maybe stupid question but the top green box with numbers is part of mother board right?, the black square at bottom(#'s 1-21), what is that?

The bottom diagram is the pinout of the connector of your video cable/AV pack that plugs into your xbox.

Yes, you can ignore it.  It is handy to have those pinouts if you were going to modify your cable but since you are going to be putting your xbox into a new case, just solder the wires directly to the bottom of the motherboard

And good luck.

Hi. What do you mean with conflicting ?
One have VGA output and the other has SCART (A common port in Europe).

I made the second diagram btw.. Is there some other problem i have missed ?

I have one clue.....
I dont know why there is a separate ground for any conector...
seems like all the grounds are all the same, right?

  It's the same on both pictures. What i wondered about was what is so conflicting between them other then one is for RGB scart and one is for VGA.

o.k. couple last questions, before i do this, the bottom diagram will work for a ntsc box correct? also anyone know how i can put led's on the front of case to show me which switches are off and which are on? and is 24 gauge wire o.k. for this?

Post by: tbirdturbo on May 05, 2006, 12:30:00 PM

also, do i still need to have the normal xbox a/v cable plugged in after doing this mod?>

Thanks for the answers....
The soldering is perfect  
The problem with noise, starts just when the output connector (gorund) from coaxial cable (xbox), touch the output connector of the receiver coaxial input...(ground)
Maybe using optical instead of coaxial could fix this problem, cause there is no direct contact with receiver and xbox ground...

carwarr, yes...you are right....Im sure its a ground problem.
But when I say "coaxial", I was talking about "coaxial digital output", thats the "spdif" output from the diagram, anyway the ground from coaxial digital output is the same ground in all the xbox, so literally I m connecting all the xbox ground to the receiver ground through this cable....
I have no idea whats the impedance of the digital coaxial cable....
But maybe you have another idea to crate an isolation transformer....  I dont know if the adapter you post, could work....that adapter doenst change impedances?
Thanks!
If I connect a screw from the xbox or the receiver to "home ground" (ground connection in my house), the noise almost dissapear (or totally dissapear...not sure), but I dont know if I can connect a screw from this components, direct to ground....
To the other guy....with this cable (from the diagram) you dont need to connect any other av cable ( neither the original av cable)

After sunday testing......

Ground in the xbox is 0V
Ground in the receiver is 3v AC (what the ****??)
So, this is the problem causing noise in the xbox video signal....



Any ideas?? What could I do to avoid this 3v difference?
