Tom,
It has been covered many, many times. All those who have purchased a
used K2 and do not have the special K2 to PC special cable, please pay
attenion - the health of your K2 may be at stake.
Do *not* plug a computer serial cable into that connector. Note that it
is labeled "AUX I/O" and that does *not* mean "RS-232"
In addition to 3 RS-232 signal lines (TXD, RXD and Signal Ground), it
contains internal K2 signals that are used to control the KAT100, XV
series tranverters and the KRC2. RS-232 level signals from a computer
port can damage those internal K2 signals, or at least cause "strange
operation".
Download the K2 KIO2 and/or KPA100 manual and build the cable that is
shown in those manuals.
You will need a length of shielded 4 conductor with ground wire, a male
and a female DE-9 connector and 2 backshells to hold the connectors.
You can plug that special cable into a computer serial port or connect
the PC end of that cable to a USB to serial adapter (use an adapter with
an FTDI chipset for best results).

Hi gang,
I think this may have been previously covered, so I apologize if I'm
redundant.
I know the cable from the K2 to the nine pin plug is not wired in a
"standard" way, but how do I go about interfacing my K2 to the USB
port on my computer?
I see this on Amazon, but I'm hesitant to try it:

Thanks for your help with this,
