K2 Use of KUSB cable with the K2

I realize this topic is not new, but it is confusing to review the archives when searching this question. The KUSB is sold to support the K3. It is not advertised to support the K2. Can it be used out of the box to support the K2? Can I plug it into the serial port of the K2 (okay not a real serial port but looks like it) and then connect it to a USB port on my laptop without damaging the K2? I thought there might be a good reason why ELECRAFT does not list it for use with the K2 as well as the K3. I seem to recall a warning about damaging the K2 when using the wrong interface, but can't find it in the K2 manual or module building instructions. Any help would be appreciated. Many thanks, and this reflector is addictive! Ron

Ron,

This topic has been discussed over just the past few days here on the
reflector.

Apparently, people are having different experiences. My K2 works by plugging
the K2's ** serial cable ** into the end of the KUSB cable and setting
up the application software to run at 4800 / N / 8 / 1.

It seems that ONE SHOULD NOT PLUG THE KUSB INTO THE K2'S AUXIO JACK for risk
of damage to the K2.

Ron, Brian,

Yes, that is correct - the KUSB should not be plugged directly into the
back of the K2 - the K2 can be damaged.
All that uses a DB-9 connector is NOT a serial port connection, the K2
is clearly labeled AUX I/O.
Use the K2 defined cable to plug into the KUSB and all will be OK (if
your KUSB works OK at the 4800 baud rate.
