RS-232 defines voltage levels (a bi-polar system greater than +3V or
less than -3V).  It *does not define a connector*.  The K2 Manual is
*entirely consistent* in saying RS-232 and Aux I/O ... the CAT pins
(2,3 & 5) are RS-232 levels, the others associated with Aux I/O (ALC, 
Aux Bus, RF, +12, and 8R) are not.

Perhaps the DB connector associated with the KIO2 could be more artfully
described as "Auxiliary I/O" or Auxiliary I/O including RS-232 control
but the "RS-232 and AUX I/O" label is technically accurate.
