3.3.4 Jog Mode
If enabled on the memory card using the CardPrep software, Jog Mode causes four of the
available seven trigger inputs to be redefined:
-
Triggers 6 and 7 are used to remotely step the DMP-300 through its menus. This is
particularly useful for helicopter installations or any installation where the pilot needs to be
able to quickly step back or ahead through the playlists and select a new track.
-
Triggers 1 and 2 are used to decrement or increment the volume level. Each activation of
the trigger simulates a push-and-turn of one knob click.
If Jog Mode is to be used, it is recommended that Triggers 1, 2, 6 and 7 each be wired to a
snap-action momentary pushbutton. They may be configured as either active high or active
low, as desired.
Trigger 6 simulates a counterclockwise knob turn followed by a button press (stepping BACK
through the playlists), while Trigger 7 simulates a clockwise knob turn (stepping FORWARD
through the playlists) followed by a button press. See the DMP-300 User Guide; document
DMP020, for complete details on the operation of Jog Mode.
