Dave,
DO NOT PLUG THE USB TO SERIAL CABLE DIRECTLY INTO THE KIO2!! It will
cause 'strange happpenings' and can even damage to the K2.
There is a special cable with a DE9 male on one end and a DE9 female on
the other end. The instructions for building it are in the KIO2
manual. it does not have to be very long, but it MUST be in place
between the USB to RS232 adapter and the KIO2 connector.

Good afternoon,
I have a K2 that refuses to talk to my computer. The computer software
works and talks to my K3s and an RT21 rotator controller using a straight
USB cables.
The K2 has a serial port and requires the KUSB cable which plugs into the
USB port and terminates in a DB-9 connector. It is warm, so I assume there
is a chip in there, doing what is required to convert USB to serial.
The KUSB cable is recognized when connected to the USB. Voltage check at
pins 5,3,2,and 1 per the KIO2 manual are good.
All looks like it would work, but it doesn't.
If anyone has experience troubleshooting this sort of thing or knows where
to get more information, please let me know.
Any help would be appreciated.
