FOOT SWITCH SEQUENCER
Additional functions can be associated with the foot switch (or hand mic PTT). MK2R recognizes when the
foot switch is closed (pressed) or open (released).
MK2R can mute or block
serial port CW, FSK, PTT
and audio when the foot
switch is activated. Each
of those inputs can be
selectively restored when the foot switch (or hand mic PTT) is released or can remain muted until all PTT
inputs are released.
Mute serial CW - if checked, virtual port CW (DTR or RTS) generated by an application program will be
muted while the foot switch is pressed. If Restore serial CW is checked, CW will resume when the foot
switch is released (if it has not already ended). If Restore serial CW is not checked, application generated
CW will remain suppressed until the application releases PTT.
Mute serial FSK - if checked, FSK generated by an application will be suppressed while the foot switch is
pressed. If Restore serial FSK is checked, FSK will resume when the foot switch is released (if it has not
already completed). If Restore serial FSK is not checked, FSK will remain suppressed until the application
releases PTT.
Restore serial PTT and audio - if checked, application generated serial PTT will be restored and audio
routing will return to the "serial PTT" setting when the foot switch is released. If Restore serial PTT and
audio is not checked, audio will only return after the application releases PTT.
