You have the physical connections right Don.

RUMlog has been replaced by RUMlogNG, available through the 
Apple App store with a donation requested. Its been a while 
since I used RUMlog, but the basic setup is similar. Mine is:

   Use CAT checked
   For RTTY use Data AFSK A
   For PSK use Data Data A
   For unknown Data use PSK
   Serial Port <The USB serial adapter you use for the Elecraft 
K3 utility>
   Baud Rate 38400
   Stop Bits 1
   Parity None
   All the Flow Control and Power Up Lines unchecked
   Interface Serial
   For PTT use: TRS CAT

These settings should get RUMlog talking to the radio. RUMlog 
will be able to copy the frequency from the radio, automatically 
setting up the entries for frequency, band, etc. It will also be 
able to make a good guess about the Mode of the QSO.

In addition, if you use RUMlogNG, there is a useful built in 
contest mode that knows about many popular contests and can set 
up the PF keys to send canned messages.

If you have any other questions, please ask.
