Edit: All new diagram.

Thanks to L33 for the VGA diagram.

How could you get s-video output?

Nice little diagram JaredC01. Add 'S' video for all the connection though so everyone can see everything.

Done .

im confused on the need for all the switches. right now i have the coaxial audio output mod done from the tutorial. Now lets say i want to add svideo and the component video outputs. would i still need the switches? Also, will i still need to have the standard xbox av cable plugged in?

JaredC01 Nice.

maxpowe2120, all AV cables for the XBOX use a combination of jumper cables in the AVIP plug to instruct the video encoder (Conexant, Xacaliber, Focus) as to what type of output to enable for the particular cable type. By making your own custom output sockets you still have to instruct the encoder. By using the three switches you are effectively cloning the job of the AVIP plug. Different switch combinations, setup a 3 bit binary instruction for the encoder.



Ignore the line marked "Output" This has nothing to do with the AVIP or encoder but is necassary for my tutorial.

The three switches are representing Pins 9(Mode 1),11(Mode 2) and 13(Mode 3). The combination of binary inputs to the encoder provides the pout formats you require to drive the sockets you install.

Thanks.

Spillage said it all...

but what about s video. i do not see anything about using s video with digital sound. also do you know where i can purchase an s video jack and compent video jacks?

ps: On the tutorial for coax audio, the pins used are different then the ones shown in your diagram? whats up with that?

Is there any easy way to get vga output like this or do you need to have resistors and stuff? I can use a pixel8 bios, that is no problem.

Would it be possible to add optical to this configuration? If so, how would it be done?

for those who did the P-2-Z's Guide to Modding your XBOX for advanced A/V here is the relationship between his pinout labeling and the one above:

The number in () is p2z's labeling, the number to the right is the label numbering above.

-i've bee looking at various tutorials and faqs over the past few days, and i finally came up with a diagram for what i want to do.




can someone tell me if this is correct and if it would work right?

also, JaredC01, you said that the component only works in high def mode. does that mean, that unless i have an HD tv, i won't get an image, or what? because i've run component video on my set through a high definition pack before with no problems.

Ok, I did this mod today to add the red and white audio on the back of me box, and its ok, but the problem im getting is if i plug the red and white in (at the same time) i only get output on one channel, when i plug them in sperately, i get audio output from both channels, wtf is goin on?? I still have my standard cable connected, is that whats causing the problem? Can I not get audio from both the back ports aswell as the standard cable?

i want to put component inputs on the back of my xbox for better pic quality but i dont have a hdtv television. can you still use component for 480i, or does it have to be 480p+?

Somebody else asked about it but i never saw an answer.

What about VGA from the RGB?

I haven't been watching this thread very much, sorry.

Since there has been some confusion, I've built a table that maps pin numbering schemes. You can use it to convert the numbering from JaredC01's diagram to DataBlitz' diagram (used in his tutorial, found here), and vice versa. If there are any errors here, please let me know. If this is too confusing, let me know and I can take it down or move it to another thread.

Note: Most of the GND pins also have suggested uses, which are convenient to use based on physical placement. For example, the GND pin nearest to the "Audio Right" pin is labeled "GND (Audio Right)."

No need to do that. Everything looks correct.

Could you add VGA to this excellent diagram? It would then be complete.

I could add VGA to it, but I would also have to add a sync seperator circuit. I'll see what I can come up with. No promises though.

After a while of working, I finally got VGA added into the diagram. Enjoy.

Amazing job man. I'm going to order that LM1881n chip and built me a VGA adapter!

JaredC01, On the VGA note, you mentioned one has to have a valid VGA bios for this to work. What bios are you reffering to?(don't know of any other but hey) is it the one the xbox is booting up with? if so, is a edited 4891 good?

I've also do't fully understand when you say one has to turn on the xbox in high definition a/v mode, does this mean I have to turn 2 & 3? even thought I have a regular, standard S-video cable?

thanks, and sorry for the lack of knowledment.

Okay I figured out what is wrong. I dont know if it something that is different with my xbox or the guide has an error but the wires that go to pin 16 & 18 need to be switched. As soon as I disconnected the wire that goes to 16 and soldered it to 18 and the one that went to 18 to 16 it worked fine.

Important question: Is there any way to get component and composite out at the same time?

I ask because I output component to my TV, but plan on installing a little LCD into my XBOX. The LCD needs to be soldered into the composite points. I will run it simultaneously with my TV.

I need an answer before I devote time and money into this mod. Thanks a lot.

Bump .

Hmm... was just thinking... should I submit the diagram as an official tutorial?

I'm in the process of modding a HD-Pack to give me S-Video and Component. So now I'm in the process of deciding what kind of switch to use.

From the great diagram on the first post of this thread, I see that I need to switch between Advanced & HDTV. Except I only want to install one little switch.

I noticed that Pins 11 & 12 are closed on both modes. so I could permanently short these connections. So now I'm only concerned with pins 9&10 and 13&14, I want to switch from one pair to the other.

Are pins 10, 12 and 14 all ground? If so, I could just get an SPDT, and connect a groung to the center pin.

If not, I suppose I'd need to get a DPDT and wire it up, so only one is closed at one time.

any suggestions?

TIA

Thanks for that Jared! I'll be modding it early next week, I'll report back how it went.

I'm working on redoing the whole diagram to make it neater... adding things as they were requested made the diagram quite messy looking. Optical will be on the new diagram.

Done... hope you all like the new diagram better .

Wow, looks very nice! I hope this thread gets pinned, if it hasn't already.

since its hard to come by specific electronic parts where i live, i had to salvage a optical out module from a old technics cd deck. The problem i have with it is that it has 4 pins insted of 3. I installed it anyway with coaxial out. The coaxial out works fine, but the optical doesnt. is anyone familiar with this 4th pin? Cheers.

As I had said in the Optical note in the diagram, only 3 types of TOSLINK Optical Jacks will work for the XBox signal. The 4 pin Optical Jack you have will not work for the XBox.
