1. Introduction 1.1 Description 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 CompactFlash™ 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 DMP-200.
2.0 Mechanical 2.1 Specifications The DMP-200 is fully contained within a 2-inch (5cm) high standard mount enclosure. Height: Width: Depth*: Weight: 2.00 in. 6.25 in. 4.34 in. 1.10 lb (5.1 cm) (15.8 cm) (11.0 cm) (499 g) (With Mounting Tray) Tray depth behind panel. Connector shell protrudes 0.25” (0.64 cm) beyond system enclosure. 2.
3.3 3.3.1 Inputs Remote Pause/Play Button An external input is provided which can either emulate the front panel pushbutton, or can be used only to pause or resume playback. When set to “Edge-Activated”, the Remote Pause/Play input going active will immediately pause or resume the playback of any audio track in progress. In addition, if the knob has been turned so that a desired track is displayed (i.e. “queued up”), activating the Remote Pause/Play input will cause the track to begin playing.
3.3.2 Discrete Triggers Three discrete trigger inputs are provided, each of which can be assigned to a particular audio track via the CardPrep software. When a trigger input becomes active, the corresponding audio track is played. Each input can be configured independently in Setup Mode as active high or active low. If more than one trigger input becomes active at the exact same time, the higher number input has priority.
3.3.3 Outputs 3.3.4 Audio The DMP-200’s stereo audio and mono outputs are ground-referenced, line-level signals with a typical signal level of 1.8 V p-p. If isolation is required, an audio isolation transformer such as a Triad SP-50 or a Magna-Tek TY-141P must be provided externally. Volume level is selected from the front panel by the user, and stereo balance is selectable from setup mode. 3.3.5 Discrete Two discrete outputs are provided for interfacing external equipment: CHIME and BUSY.

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.
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.
4.1.9 Test External Outputs This page allows the installer to cycle through all the DMP-200 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 • Volume turned down.
