I asked the seller what the gray pigtail was for and how you
would use this with a 16500, and as usualfrom an eBay seller,
got no reply.
I have several of these, and when I opened them up they are
completely passive with no connections between the PS2 and
HIL connectors. The pigtail plugs into a 10 pin RJ style on
the back, and the other three connectors run over to it.
My 16500B has a connector on the front for an optional keyboard
and it looks like the pigtail on that box would plug into it. So
I would guess it allows a PS/2 style keyboard to be used on the
analyzer. If you have an extra, I wouldn't mind having one...
