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. Optionally, the DMP-200 may be connected to a maximum of three external
discrete trigger inputs, each of which can be configured in software to select a particular
audio track.
The DMP-200 accepts a power input of between 10VDC and 35 VDC and provides a
single pair of ground-referenced stereo line-level audio output signals. A Mono output
which combines the Stereo line level outputs is also available.
The DMP-200 has been designed and tested to the Environmental Specifications of
RTCA DO-160E. An Environmental Qualification Form which describes the various
parameters and the levels to which they were tested is available upon request from
Avionics Innovations.
1.2Scope
This document describes the installation and initial checkout of the DMP-200 Digital Media
Player. It may be used to support all installations, including those intended for initial Type
or Supplemental Type Certification approvals and FAA Form 337 Field Approvals.
1.3Installation Kit
Before beginning the installation, verify that the following items are present:
The DMP-200 should be installed in a normally heated, pressurized section of the aircraft;
however the unit contains no moving parts and does not require special vibration isolation.
The unit may be mounted in an auxiliary area of the instrument panel, in a pedestal, or
anywhere in the aircraft cabin outside of the cockpit. In a severe vibration environment,
the unit should not be mounted vertically with the front panel facing down, to ensure that
the memory card does not accidentally vibrate loose. Otherwise, the DMP-200 may be
installed in any orientation and at any angle.
3.0 Electrical
3.1 General
