- On the back of the motherboard, solder these four points to your SPDIF board or TOSLINK adapter.
- Solder +5V to pin 7 of the TC9231N and connect GND to your SPDIF board or TOSLINK adapter.
- Mount your SPDIF/TOSLINK PCB. This is one suggested location, but it may depend on what devices you may have installed in your unit.
- Mount your external jack. This is one suggested location, but may require trimming of the case.
