RS 232 connection failure

[Bob Jones-9]

Hi

my K2/100 Nr 5336 has fallen out with my PC - they've stopped talking  
to each other. I use microHAM's USB device router and a number of  
serial to USB adapters, all of which have worked fine until now. The  
same adapters work perfectly with my Icom rig but I get no response  
when the PC polls the K2. I use VQLog for general logging and  
Writelog for contests - neither will now work with the K2. Done the  
obvious stuff  - checking that the port is switched on at the K2 and  
checking all the connections on the DB9 adapter lead. I also use the  
KAT100 and have tried with it connected and disconnected - no  
difference.
Any ideas on where I can start looking for the fault would be very  
welcome.

Hello Bob,

I had this problem and tracked it down to a menu setting.  Look on page 86 of
the K2 manual under the heading 'Using the menu'.  Tap [MENU] and select the
sidetone level ST L.  Hold EDIT so that you get the sidetone output and can
adjust the level.  If you can't hear anything from the speaker (assuming the
level is high enough) tap [DISPLAY] and the LCD will alternate between U6-25
and U8-4.  Tap [DISPLAY] until you get sidetone from your speaker.  The
reason for all this that the RS-232 TXD output from the microcontroller used
to control the sidetone in the original K2s.

Hope this helps.
