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!
