DIGITAL modes are: PKT, DIG and DATA. There are four available settings. PTT2 Immediate is
–
appropriate for applications which provide for setting a PTT lead time. PTT2 delayed should be used
with applications which do not permit setting a PTT delay. PTT1 immediate should be used when radio
does not have a dedicated digital mode input and you must use the microphone (or Patch) input.
(No PTT) is suitable only for testing purposes.
FSK modes are: FSK, FSK-R, RTTY and RTTY-R. Three PTT settings are available. Of the three,
–
PTT2 delayed is strongly recommended when using a power amplifier in order to prevent hot switching.
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 manipulate CW, FSK, PTT
and audio routing differently based on
the state of the foot switch
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.
If an external PS/2 keyboard is attached to the MK2R, Router supports additional settings for FSK.
Diddle LETTERS will generate the "LETTERS" character if nothing is being typed
UOS implements the "Unshift on Space" function when checked
Type ahead enables a type ahead buffer for the keyboard.
