[Elecraft] K2 Not Talking to Computer

[Louis Visconti]

I'm sure this question has been answered before, if someone could point me 
in the right direction, I would appreciate it.
PC and K2 not talking. K2 Port ON; Computer-4800 baud, 8 data bits, no 
parity, 2 stop bits. Cable connections look good, RTS/CTS Loopback not used. 
Trying to use this setup with N1MM Logger. I can see the transceiver 
frequency in the software and it does respond to frequency changes and band 
changes, but thats all. Do I now check the voltages on the KIO2, or is there 
another place to look first?
