This tutorial will show you how to modify your XBOX so that you get S-VIDEO (erroneously called S-VHS) and digital audio (SPDIF or OPTICAL) out. This make your xbox look and sound much nicer!!! I have tested this on a xbox and it works great :)
WHAT YOU NEED BEFORE YOU ATTEMPT THIS
+-------A/V Connector | | +---------PINS \|/ \|/ ' ' ==| 2 1 ==| 14 13 ==| 4 3 ==| 16 15 ==| 6 5 ==| 18 17 ==| 8 7 ==| 20 19 ==| 10 9 ==| 22 21 ==| 12 11 ==| 24 23
Note that the basic design WILL work - it's just not compliant with the standard. One can make a simple modification so that it will work. Just a 100nF capacitor and 330R resistor in series with the DATA pin (Pin 3) and then a 100R resistor in parallel between the new output (From the end of the 330R resistor) back to GND is all that is required.
So the wire going to your RCA socket should look like this, with SPDIF DATA (pin3 going to center leg, and SPDIF gnd (pin5) going to outside leg.
---p-i-n-5----===+----------+ | / \ ---p-i-n-3----===+ | | | \ / +----------+You now have a working SPDIF digital sound output connection, You just need to enable it in the software now. Start the MS Dash and choose audio settings, you must now choose Dolby surround, and then enable Dolby 5.1 and DTS. Your SPDIF will now output these surround modes, check that your surround processor is getting the right signal, and enjoy surround sound :)
I chose to mount my SPDIF connector at the back / top / center of my xbox,
where there was no need for drilling as I could simply run the wire out the
small gap where the fan is.
one CAN get this working WITHOUT the AV cable plugged in - you must jumper pin 17 to pin 5 and then jumper pins 17 and 6. This will then allow the XBox to boot without the AV Cable plugged in - much nicer than having the AV cable plugged in but not connected to anything
S-VIDEO Please note excellent wiring diagram =-D
