The system board is equipped with an onboard RCA S/PDIF-out
jack and a RCA S/PDIF-in jack at locations CN5 and CN7 respec-
tively. It is also equipped with a connector at location J3 for optical
S/PDIF connection. S/PDIF ports are used to connect audio output
devices.
Your optical S/PDIF may come mounted on a card-edge bracket.
Install the card-edge bracket to an available slot at the rear of the
system chassis then connect the audio cable connector to J3. Make
sure pin 1 of the audio cable connector is aligned with pin 1 of J3.
Important:
DO NOT use optical S/PDIF and coaxial RCA S/PDIF at the
