[Elecraft] kx3 acc1 port - description?

[Don Wilhelm]

Terry,

The KX3 end of the KXUSB or KXSER is a 3.5mm stereo plug.  TXD (data 
from the computer) is on the tip and RXD (data to the computer) is on 
the ring.  The shell is signal ground. AFAIK, the KXSER cable is the 
same as the one supplied with the XG3
