That particular cable is a transitional configuration and is the only one I do not have well documented. I can check tomorrow to see if I have one of these (or one of the BIV versions) kicking around in one of my "stash" bins... I am a parts hord hound.

OK... here it is...

Facing the 8 pin male plug with two pins on the bottom and three on the top, count pins 1-8 left to right and bottom to top (pin 1 in the lower left and pin 8 in the top right). This is the inverted view from the female layout.

On the RJ45 is, of course, 1-8 left to right with tab down and end facing away from you.

RJ45 pin1 = male 8 pin7 = data (left pair white conductor)
RJ45 pin2 = male 8 pin5&8 = ground (left pair drain common at male 8 end)
RJ45 pin3 = N/A
RJ45 pin4 = N/A
RJ45 pin5 = male 8 pin5&8 = "audio" reference ground (right pair drain common at male 8 end)
RJ45 pin6 = NA
RJ45 pin7 = male 8 pin1 (right pair white conductor) = SPDIF 0
RJ45 pin8 = male 8 pin2 (right pair red conductor) = SPDIF 1

I am not sure of the polarity for the SPDIF because Bose only documents 0 and 1.

Tried to put the cable back? What does that mean exactly?

Did you try and stick the old plug back on? That will not work.

You must power the system off, properly reterminate the end, test the cable, hook it back up with the power off and then reapply power to the system.

It may help to be a little more specific about what and how things have been done.

well tried to retrofit a new rj45 plug with the pinout, and no audio, just the blinking led on the ps28, i did test the cable alone with a multimeter, each pin like described but no audio whatsoever not even hiss in the speakers or subwoofer.
tried on, off, unplug 20 min etc. but no luck.

I think it would not be an easy cable to terminate but I assume by your post that the pin assignments tested out.

Pins 7 & 8 on the 45 plug will carry the audio signal, 2 & 5 are grounds that common on the male 8 pin end along with the shell and pin 1 will provide the turn on and volume data.

You can test for proper line level voltage on the 45 pins with the cable plugged into the media center.

Now that IS odd.

Sorry, couldn't resist.
I guarantee I'll tell you the truth and I guarantee I'll tell you what you need to know but I can't guarantee that I'll be telling you anything you want to hear.

thanks tgrugett got it working now, but it has no volumen control and the 2-3-5 and surround +,- speakers are not working, if you turn the volumen up to 50 and then you turn off the system, and the on it would go to that level, but not response from the remote or the media center until you do that secuence i just told you. and the audio menu shows no speakers conected, but they are working.
everything is in zone-1.
