[amsat-bb] Cat/Pin numbers NON Sat Question

Does anyone know the pin numbers for the back of the computer/soundcard?

I have a new Yaesu FT-7900 cable and one of the wires is black instead of blue like the manual says...

How do I know what number the pins are on the computer side of the cable where I would connect the ends too I am sure that is standard?

Any help would be greatly appreciated, not having any luck looking it up on the web.

Thanks Kevin KF7MYK
