[Elecraft] Connecting a KXUSB to the K2 RS232

[Don Wilhelm]

Hans,

Does the USB to RS-232 cable have an FTDI chipset?  I know that works OK 
with the K2 (at least the one used in the KUSB).  Others fail with the 
slow 4800 baud rate required by the K2.  I have had good success with my 
Edgeport serial converter as well.  A Prolific chipset adapter may or 
may not work.

You still need to build a cable having only 3 conductors to isolate the 
non RS-232 pins from the serial port, even though it may be short.  The 
AUX IO to PC cable is shown in the KIO2 and the KPA100 manual.

73,
Don W3FPR
