1.0 Introduction 1.1 Description The DMP-100 Digital Media Player is a self-contained unit which stores and replays prerecorded audio tracks. The audio tracks are encoded in “Motion Picture Expert Group (MPEG) Level 3” format, commonly referred to as “MP3”. Audio files are stored in a removable Compact Flash™ memory card which is prepared and installed by the user. Audio tracks are selected via a single rotary pushbutton on the front panel of the DMP100.
2.0 Mechanical 2.1 Specifications The DMP-100 is fully contained within a 2-inch (5cm) high standard DZUS mount enclosure. Height: Width: Depth*: Weight: 2.0 in. 5.75 in. 5.0 in. 3.25 in. 0.75 lb (5.1 cm) (14.6 cm) (12.7 cm) (8.26 cm) (350 g) Front Panel System Enclosure * Connector shell protrudes 0.25” (0.64 cm) beyond system enclosure. Allow an additional 2.5” (6.35 cm) behind unit for mating connector and wiring. 2.
3.3 3.3.1 Inputs Dimmer The vacuum-fluorescent display on the DMP-100 can be set to one of four different levels of brightness in Setup Mode. Alternatively, the brightness level may be selected via the external dimmer input. Three different inputs are provided for each of the three common types of dimmer busses: 0-5VDC, 0-14VDC and 0-28VDC. Connect the aircraft dimmer signal to only one of these inputs. The two remaining unused inputs must remain unconnected.
Like the discrete trigger inputs, Remote Pause/Play is floating and must be pulled up or down with an external resistor, depending on the desired active state. The input signal may vary between 0V and 35 VDC: levels above 3.5 VDC will be interpreted as “high”, while levels below 3.5 VDC will be “low”. When Edge-Activated is selected, the Remote Pause/Play input works in parallel with the front panel knob – playback may be paused via one and resumed via the other.
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-100 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.
3.4.2 Discrete Two discrete outputs are provided for interfacing external equipment. BUSY and CHIME are both open-collector outputs capable of sinking 1 Amp each. Maximum input voltage is 35 VDC on each. By default, BUSY is active anytime the DMP-100 is producing audio. However, the installer may configure BUSY to go active only for speech tracks, only for music tracks, for all types of tracks, or even to never go active at all.

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 removing power (there is no ON/OFF switch) 2. Depress and hold the front panel knob. 3. Apply power 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 to the unit.
4.1.5 “LOUD” Volume Level The playback volume level is normally set by turning the front panel knob while holding the knob pushed in. However, the CardPrep software allows the user to designate any track to be played at a “LOUD” volume setting. This is normally applied to speech tracks such as important safety messages.
4.1.8 External Pause Signal Type The external Play/Pause input signal can be treated as either an “EDGE” or a “LEVEL”. If “EDGE“ is selected, the play/pause function will toggle each time the external button is pressed-and-released. If “LEVEL” is selected, the DMP-100 will remain paused as long as the external button is held down, and will resume when the button is released. Press the button to toggle between “EDGE” and “LEVEL”. The factory default value is “EDGE”. 4.1.
4.1.11 Test External Outputs This page allows the installer to cycle through all the DMP-100 external outputs, setting and clearing each one in turn. This function is used during the installation checkout procedure, and may be used any time an external output needs to be tested. Each press of the button will activate one output and clear all others except the “All OFF” selection, which turns off all outputs. 4.1.
6.0 Troubleshooting and Error Messages 6.1 Troubleshooting Here are a few common problems and their potential causes: Symptom Possible Causes/Solutions • Not using a Sandisk card maybe a possible cause of failure. Only Sandisk brand cards should be used in the DMP100 • Volume turned down. Last volume setting is retained between power cycles, and previous user may have turned volume way down. Push-and-turn knob to change volume. • Invalid MP3 file used.
6.2 Error Messages In addition, the DMP-100 may display the following error messages: Display Meaning Invalid Card, no firmware. The firmware update file, “000.hex”, cannot be opened on the CompactFlash card. Invalid Card, no MP3 config. The MP3 configuration file, “000.xd3”, cannot be opened on the CompactFlash card. Internal error number XX A fault has occurred between the two internal processors of the DMP100.
