Sorry for not being about much recently, had loads of electronics coursework at uni.
Just been made aware that Imageshack somehow lost one of my images I had hosed there, and as I can't edit my original post with a newly uploaded image I've had to add this post.

Sheepie,
if you just want one video mode, HD in your case, then yes, by all means you can just solder a wire from ground to the mode pins you need (ground to mode 2, ground to mode 3)

Video Mode Select

Hi,

I've been busy with all the components and had everything nicely working at HD output on my beamer.. But I am having trouble putting back the full xbox together afterwards. So I decided to get rid of de AVIP and get me more space for all connections, nicely on the back of the back of my box.

But I can't get the solder to melt or even loosen up. What temperature should I use and is flux really going to be the anser?

Really want my VGA/Advanced AV working, it's beautiful!

Sorry for the mixup.... I have just been looking over my table of Video Modes and realised that I got pin 13 and pin 9 mixed up.....
I am currently trying to find a way to update the images on imageshack without having to repost them with new links.

I found this: http://www.newark.co...NDUCTOR-LM1881N and want to order from here. Can someone point out what else i need to order and show me were it is on this web site so I can order it all together

My LM1881N chip is on its way. does anyone know what part number to look for for the 680k resister and 0.1uF Capacitors that they would carry in most radio shacks?

Can someone repost the image fromt eh first page. The actual pinout and connection image. It is getting a image link error and I need the image for reference.

Thank you so much! I had just stumbled accross that tut and bookmarked it, because it was the most visual and understandable one around. Then 3 days later I went to look it up and the pic was gone. Thanks again

also if i did the high def a/v mod do i need the orange wire and the optical & coaxial for it to work ?

It has been quite awhile since I last posted in this topic.

If you are using sync separators then I recommend the ISL59885 from Intersil. It is just like the EL1883 except it no longer uses an RSET resistor. Instead you connect a 56nf capacitor to a certain pin and it will auto-sync to any sync rate on the fly. Oddly enough, even though I have some samples, I have not built anything with them.

I am interested in playing with the sync signals from the motherboard. However, the pictures I have seen of sync signal acquisition come from an earlier mobo with a Conexant chip. Are there any pictures of mobo sync acquisition from a mobo with a Focus chip?

Hi guys I'm sorry, I'm a newbie and I would like to know what's this scheme for ?
I mean, A/V Pack is a separate hardware, or the scheme refers to internal A/V board ?
It works for a 1.6 version ?
which kind of bios do I need in mine ?

It's for building your own cable to output the various formats of video and audio the Xbox will support

You can do either internal or external - this just shows you how to wire it.

QUOTE

Yes, apart from the VGA output.

QUOTE

Any BIOS. For VGA you would need a VGA BIOS, but unfortunately there isn't one for the 1.6.

Hey guys, I'm planning on modding a Advanced A/V Pack so I can have Component connectors housed on a neat package without the need of drilling extra holes to the Xbox case. I know the A/V pack I'm using does not have the sufficient wiring to put a extra set of connectors. So I'm planning to hack the cable connector to add a extra set of connections for the Component lines.

I have a spare USB cable lying around and I though I could add like a extra cable to the connector and stick that neatly on the side of the original A/V pack cable and run it to the A/V box where I would do all the connections and stuff.

But I'm wondering, could I ground all Component signals with one ground?? The thing is the USB has 4 cables in it (Red,Green,White,Black...... and some type of shielding but thats ground as well) and I'm going to use this because I don't want to make a huge tangle of extra cables running along the side of the original one to the box.

Example:
USB Cable Color ------- Component Connector

Red --------------------- Red Component Connector
Green ------------------- Green Component Connector
White -------------------- Blue Component Connector
Black -------------------- Common Ground for all Connectors <-- ***Is this possible ??***
Wire Shielding ---------- I guess this one won't be used

Is this connection is do-able or do I have to have a ground specific ground for each one?

It is possible but picture quality could suffer due to interference, for video signals to reduce the interference to the signal the signal wire is normally surrounded by the ground wire (i.e. coaxial), also having individual ground wires for each part of the video signal is ideal, but my cheap HD xbox cable used a common ground. So try it out and see, but if the picture suffers from interference then that is probably your source of it. Also I would consider using the wire shielding for ground vs. just the black wire, therefor protecting the signals from outside interference (but they would still be able to interfere with each other being surrounded by a common ground and not there own).

Hmm... So I think the best option would be to use the black one for ground to the Green channel, and the shielding as a ground for both red and blue channels since both are almost the same signal. Hmm I think it might work.

Ok so all I would need is a couple of Component/RCA jacks and a switch. The switch would be easy to install. Just a switch with 3 terminals, the middle one would be the common ground for mode select, then one side with the HD mode pin and the other with the Advanced mode pin. There is a set of pins that both modes use by default, so I just need to bridge them together and hook up the switch the way I want it.

I'm gonna do a diagram and see if my design works.
