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

[Kevin Deane]

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
