[Elecraft] kat500 can't be seen by kat500 utility

[Jim Brown]

Thanks Don. I made my adapter years ago when the KAT500 arrived in my 
shack for beta test. It may have been nothing more than designating the 
RS232 functions assigned to tip and sleeve. Or maybe I had to ask 
someone. In the past, pin assignments for all connectors was in the 
manual. It's very disappointing to see this practice discontinued. It 
has the effect of turning hams more into appliance operators.

Looking at the XG3 manual, the 3.5mm ring is wired to pin 2 of the DB9 
female, the tip to pin 3, and the sleeve to pin 5. Pin 8 is jumpered to 
pin 4.  My adapter does not include that jumper.
