4.0 Setup Mode
4.1 Entering and Exiting Setup Mode
Setup Mode is entered via the following steps:
1. Turn the unit off.
2. Depress and hold the front panel knob.
3. Switch the unit on while continuing to hold in the front panel knob.
4. Release the knob when the display first lights up. After the 5-second intro
screen, the first Setup Mode item is displayed.
Setup Mode is exited by simply cycling power on the unit.
Turning the knob once Setup Mode has been entered allows selection of the following
setup items:
4.1.1 Discrete Triggers 1 Through 3 – Active Level
The current active level of each of the three discrete triggers, TRIG1 through TRIG3 is
displayed. Pushing the front panel knob toggles each between “ACTIVE HIGH” and
“ACTIVE LOW”. The new settings are immediately written to permanent memory – no
explicit “save” action is required.
4.1.2 External Pause – Active Level
The current active level of each of the external PAUSE input is displayed. Pushing the
front panel knob toggles each between “ACTIVE HIGH” and “ACTIVE LOW”. The new
setting is immediately written to permanent memory – no explicit “save” action is required.
4.1.3 External Chime Length
The CardPrep software offers the user the option of activating an external chime prior to
playing a speech track. The “EXT CHIME LENGTH” setup item determines how long the
unit waits, with the CHIME signal asserted, before de-asserting the CHIME signal and
playing the speech track. Pushing the front panel knob cycles EXT CHIME LENGTH from
0 to 9 seconds.
CardPrep also offers the option of an “internal” chime, which is simply a selected MP3 file
(usually a recording of a chime of some type) that is played before each speech track.
Note that if a card specifies an internal chime, the CHIME output is not activated.
4.1.4 Display Brightness
The DMP-200’s display can be set to one of eight brightness levels. Each push of the
front panel knob cycles through a brightness level between 12.5% and 100%. Set this to
a level appropriate to the expected cockpit lighting conditions.
