[Elecraft] K2/10 I Idiom Press CMOS4 Keyer Conflict

Hi All,

I have a K2/10 and an Idiom Press CMOS4 keyer that I would like to use together.  I have everything connected properly, the K2 set to "Hand" for the input device, and the the cables I made are properly fashioned and not shorted.  HOWEVER, when I go to send (on either side of my paddles) the K2 goes into total key-down, and the only way to stop it is to turn the rig off OR disconnect the CMOS4.  The CMOS4 doesn't seem to be malfunctioning.  When I just have paddles connected to the K2, and use the internal keyer, everything works fine.  Also, when I have the K2 set to "Hand" and the paddles connected, everything works fine.  I am not sure if the problem is with the CMOS4, K2, or both.  I know the CMOS4 works properly since I have been using it since 2008 on my ICOM with nary a problem.  Any ideas/input would be appreciated.  If the problem is in the CMOS4, I'll E-mail Rob at Idiom Press, but I figured that I would start here.

Thanks & 73,
