Raymond,
It would appear that you are mixing "apples and oranges".
The K3 and the K2 are different in the connections required.
If you are dealing with a K2, then your question begins to make some
sense. The K2/100 connection to the computer is a subset of the RS-232
spec. It only uses TXD and RXD and signal ground. No other pins should
be connected to a serial port.
The connection to the KAT100 uses pins different than the RS-232 defined
pins 2 and 3.
The cable should be constructed as indicated in the KAT2 manual. Pins 2
and 3 go to the cable that connects to the computer and the KAT100
connections are from the K2 internal signals to the KAT100.
In other words, build the cable as shown in the KAT100 manual, and it
will work FB with the K2. AFAIK, the KAT100 cannot be used with the K3.
