KRC2 Accessibility Configuration Event Operations
The KRC2 operates by listening for information from the K2 over the serial port or from the keys,
then performing some operation. The incoming information creates an event, which causes an
operation to be executed. There are four levels of event detection that may be set by the user. In
the accessibility configuration, these are used to set the amount of information announced by the
KRC2. Thus at level 1, only information requested by the KRC2 is announced. At level 2, this
information is extended to include button and knob changes from the KRC2, but does not include
frequency QSY changes within a single band. The third and fourth levels add this information,
with minimal identification information added at level 3, and full identifiers used at level 4. The
listing below shows, for each level, the events that the accessibility configuration recognizes and
the action taken.
Status information for on/off parameters is announced with an ‘F’ for Off, and an ‘N’ for On.
Normal Morse numeric characters are used in values, except for the 0, which is shortened to an
extra long ‘dah’. The letter ‘R’ is replaces a decimal point or period.
