[Elecraft] [KPA500] Serial Port Connections on KPA500

[Dan Atchison]

Team:

Now that I have completed my KPA500 (S/N 196) I have a question 
regarding serial port connections.  I have the current, complete K-Line 
(K3, P3, KPA500).

1. Do I need to put the KPA500 in the serial port chain?  After all, it 
does have a serial port goes-inna and goes-outta.
2. Is it really necessary?
3. If there are benefits, in what order should they be chained.
4. Then, what are the benefits?

Reason I ask, I just did the following chain things are not working 
correctly.  Serial port - P3 - KPA500 - K3.

Obviously, I am missing something.

Thanks,
Dan
