Optical (TosLink) instruction -
Parts required:
- Toslink Optical transmitter TOTX173 or TOTX176 or TOTX178a
- 100nF capacitor
- Some thin insulated wires, solder and a low wattage soldering iron with a fine tip, a torx screwdriver
Instructions:
1. Open the Xbox (voiding your warranty)
2. Remove all the drives and remove the mainboard. Flip it over and locate the AV connector (as pictured)
3. Solder a wire from Pin 3 of the AV connector to the data leg of the TosLink connector. *
4. Solder another wire from Pin 5 of the AV connector to the ground leg of the TosLink connector. *
5. Solder another wire from Pin 13 of the AV connector to the Vcc leg of the TosLink connector. *
6. Link a 100nF capacitor between the Vcc and Ground legs of the TosLink connector.
7. Solder another wire from Pin 18 of the AV connector to a grounded point on the board.
8. Find somewhere you would like the socket to stick out the case (make sure there's still room for it there when the case is put back together), and drill a hole and mount it there (depending on the TosLink socket it could mount in one of various ways, you will need to work this out for yourself)
* There is a hole in the mainboard located near the LAN connector, it is right next to where the '8' co-ordinate is printed. This hole is big enough to fit the power wires through so the optical connector can be above the mainboard when reassembled, the 3rd (data) wire will fit through another smaller hole located between the AV connector and the LAN connector, just above the pin 3 hole of unused J6A1, if you cant squeeze 3 wires through the other larger hole.
