4.0 Setup Mode
4.1 Entering and Exiting Setup Mode
Setup Mode is entered via the following steps:
1. Turn the unit off by pulling on the on/off knob
2. Depress and hold the front panel rotary knob.
3. Apply power by pushing in the on/off knob while continuing to hold in the front panel
rotary knob.
4. Release the rotary 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 turning off 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 7 – Active Level
The current active level of each of the seven discrete triggers, TRIG1 through TRIG7 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-300’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%, or EXT. DIMMER.
Set this to a level appropriate to the expected cockpit lighting conditions, or to select an
external dimmer control voltage to select the display brightness level.
