Shuttle FS50 mobo SPdif woes!

hello all
Newbie here requesting assistance! Beware of anal/cranial inversion
I'm trying to connect my Shuttle FS50 jumper connections to RCA panel mount connectors (feedback requested here??) on my computer for input to my JVC 6040B audio receiver. I have three jumpers on my mobo that if properly wired by means of a pigtail to the rear panel should provide the digital output I need. As far as I am able to discern, I have two digital inputs and two digital outputs from the jumpers on the mobo. I would like to input my DVD burner and have one digital output for all audio leaving the computer. Any suggestions on how to accomplish this task would be greatly appreciated.
The following is a list of pin assignments on the mobo listed as:

SPDIF Ext/In/Out Headers (JP9/JP10/JP11)
JP9/JP10/JP11 can be used to connect special devices.

JP9
PIN1 = +12v
2 = N/A
3 = N/A
4 = SPDIF-OUT
5 = SPDIF-IN 1
6 = GND
7 = SPDIF-IN 2 (optional)
8 = SPGPIO
9 = KEY
10 = GND

JP10
Pin 1 = GND
2 = SPDIF-IN 2 (optional)

JP11
PIN 1 = GND
2 = SPDIF-OUT
