Dear Peter,  Marc,

   Thi and I have prepared a webpage documenting all the cables and
connectors inside the NPS box. Please check:
https://wiki.jlab.org/cuawiki/index.php/Cables

Let us know of any additional information or documentation you might need.

And thank you very much for your help!

Best,
Carlos
