1.0 Overview The DMP-200 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 DMP200.
1.1 File Types Each audio file contained in the DMP-200 memory card must be designated as either “speech” or “music”. While the actual audio content is irrelevant, this designation controls how each file is presented on the DMP-200 display. 1.1.1 Speech Files Every “Speech” file has a title and a language, as well as trigger and display attributes. Speech files may be selected individually for playback either from the front panel or via an external trigger.
2.0 Display Turning the knob CCW or CW will scroll left or right through the top-level menu. The toplevel menu consists of (from left to right): ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ “CHOOSE LANGUAGES” (click for language selection menu) (title of SPEECH FILE 1) (click to play) (title of SPEECH FILE 2) (click to play) (etc.
3.2 3.3 3.4 3.5 Playing a Speech File Rotate the knob CW or CCW until the title of the desired file is displayed. If “RETURN TO MENU” is displayed at either position, push the knob and then rotate fully CW or CCW. Push the knob to begin playback. The file will be played once for each language enabled, if the file exists in those languages. The display indicates that playback is in progress. This display can either be elapsed playback time, or can be cycling user prompts.
3.6 Changing Volume Level 3.7 Push and turn the knob in either direction. The volume can be adjusted even if no track is playing. When adjusting the volume, the display will temporarily display: “Volume: XX” where “XX” is a number between 8 (min volume) and 100 (max volume).
5.0 Creating MP3 Files CardPrep allows you to prepare existing MP3 audio files, but it does not provide facilities to create them. There are literally hundreds of applications available which allow you to convert audio CDs, tapes, or even phonograph records into MP3 files. Many also record from your computer’s microphone directly into MP3, allowing you to generate your own speech files. Most of these applications are either free or are very reasonably priced.
6.0 Preparing a Memory Card with DMP200 CardPrep 6.1 Installing DMP200 CardPrep The DMP200 CardPrep software may be distributed on either the CompactFlash™ card included with the DMP-200, on a CD-ROM or downloaded from the Avionics Innovations website at www.avionicsinnovations.com. Please note that the DMP100 and DMP200 each have their own CardPrep application, and are not interchangeable. To install the software, simply run SETUP.EXE and follow the prompts. 6.
1. Click on the small box under (1), type the display title of the speech file, and press Add. Repeat for all remaining speech files. 2. Click on the small box under (2), type the first language to be displayed, and press Add. Repeat for all remaining languages. 3. Click on a title in the large box under (1), and then click on a language in the large box under (2).
1. Click on the empty box under (1), type the name of the desired Music List, and press Add. Repeat for all remaining Music Lists. 2. Click on the empty box under (2), type the first music track to be displayed, and press Add. Repeat for all remaining music tracks. 3. Click on a Music List in the large box under (1), then click on a Music Track in the large box under (2).
6.2.2.2 Adding a Folder of Music Files If all your desired music files are organized by folder, it may be much more convenient to import an entire folder per music list. Click on Add Folder… and CardPrep will use the folder name as the name of the newly created Music List, and will add the contents of the folder as Music Tracks. Use the Edit buttons to fix up the List or Track names as needed.
MP3 managers such as WinAmp and MusicMatch save their playlists in either “.txt” or “.m3u” format, both of which can be read directly by CardPrep. iTunes playlists are embedded in the iTunes library and cannot be read directly by CardPrep. iTunes users must first export their playlists to “.txt” so the playlists can be read by CardPrep. (In iTunes, right-click the playlist, select “Export Song List…”, and change the “Save as type:” box to “Text files”.) 6.
6.3.2 Endless Looping This attribute is only available for music tracks. When set, the selected music track will repeat endlessly when it is played either via a trigger or by an explicit selection from the front panel. The track will not loop if it has been selected via either “CONTINUOUS MIX” or via “PLAY WHOLE LIST”. 6.3.3 Normal vs. LOUD Volume Any track can be played at either the currently-set volume level or at a pre-determined “LOUD” setting.
6.4 6.4.1 To Select Setup Items: Default Languages Enabled Select and highlight one or more languages to be enabled on power up. Note that this screen is potentially confusing: the desired language(s) must be highlighted to be selected. If none are highlighted, the list simply displays the languages on the card. 6.4.2 Custom Card Titles Up to two lines of 16 characters each can be displayed on the DMP-200 after the initial screen on power up.
6.4.4 Selecting Internal or External Chime The DMP-200 may be interfaced to an external cabin chime or tone generator. A chime will be sounded whenever a speech track is selected or triggered (selecting or triggering a music track will not sound a chime.) When sounding an external chime, the DMP-200 will pause for several seconds before starting to play the track, to allow the chime to finish. The exact length of this pause can be configured in Setup Mode.
To make changes to the text, simply click in a box on the right side, type in your new text and click “Save”. Use caution (and common sense) when making changes! Always refer to the original text in the left column to be sure you are not changing the intent of the text. As with all the other configuration settings in this section, any changes made here will only apply to this card. Inserting a different card will cause the unit to reload the configuration and clear the changes.
6.5 To Copy all Files and Settings to the Card: When you are ready to generate the actual memory card, click on the “Create Card” tab: CardPrep will run through your configuration settings and check for inconsistencies, such as languages with no associated speech tracks or empty music lists. Any inconsistencies will be displayed and described. The Create Card button will be disabled as long as any inconsistencies are flagged.
6.6 To Save or Open a Card File Your entire “workspace” can be saved to a card file (*.CRD2) so that you can easily maintain multiple cards. Click on File in the menu bar at the top of the window, and then either Open, Save, or Save As as is typically used in most Windows applications. 6.
5) After “Speech #2” completes, “Song #8” will not resume. Instead, the DMP-200 becomes idle, which causes the “Continuous Mix” to be selected. Continuous Mix will then choose a random music track, which will start at its beginning. The final situation is that after all triggered audio tracks are completed; the DMP-200 will always be playing some kind of music. In many applications, this is exactly the desired effect. 7.0 Troubleshooting and Error Messages 7.
7.2 Error Messages In addition, the DMP-200 may display the following error messages: Display Meaning Invalid Card, no firmware. The firmware update file, “0000.hex”, cannot be opened on the CompactFlash card. Invalid Card, no MP3 config. The MP3 configuration file, “0000.xd3”, cannot be opened on the CompactFlash card. Internal error number XX An fault has occurred between the two internal processors of the DMP200.
8.0 Instructions for Continued Airworthiness The DMP-200 is designed to not require regular general maintenance. No action is required.
