[Elecraft] [OT] K9YC's Serial Cable question

[Brian - N5BCN]

I read Jim Brown's very informative article on RFI and want to use his method
to construct a K2/PC control cable using some CAT5 cable I have laying
around.  Hopefully Jim or someone knowledgeable about this cable can answer
two questions:

For UNSHIELDED twisted pair CAT5:
The K2 instructions use Pin 5 for the signal return lines.  Using K9YC's
method, would I connect the return lines to the DB9 chassis, and then bond
Pin 5 (or Pin 1, or both) to the chassis also?

For SHIELDED twisted pair:
The K2 instructions say to connect Pin 1 to the shield on the K2 end, leave
the shield open on the PC end.  Using K9YC's method, would I connect the
returns to Pin 5, shield to the DB9 chassis on both ends, and then bond Pin
1 and 5 to the DB9 chassis?

Thanks!
