EXTENDED DMU
IDENTIFICATION
FIN: 1TV
LOCATION
ZONE: 127, RACK 87VU
COMPONENT DESCRIPTION
Compared to the basic one, the extended DMU is equipped
with:
- an additional microprocessor board (slave) for
expanded customer programmable functions.
- a Personal Computer Memory Card International
Association (PCMCIA) interface to upload,
download and record data on an internal and
high capacity removable media.
The DMU front panel is equipped with:
- an access door to the test connector and to a
two-position ON/OFF switch.
The operating logic of this switch is the same
as the one described in the previous topic for
the OPERATING/STORAGE switch of the basic DMU.
- a DMU Fail LED.
- an access door to the PCMCIA disk.
- a window to display the 2 LEDs providing
feedback on the PCMCIA disk operation.

DAR/ODAR
IDENTIFICATION
FIN: 2TV
LOCATION
ZONE: 127, RACK 87VU
COMPONENT DESCRIPTION
The Digital AIDS Recorder (DAR) is an optional
component of the Aircraft Integrated Data System
(AIDS).
There are several vendors and two different storage
media:
- Either a cassette (50 hour magnetic tape),
- or an optical disk. The recorder is so called Optical
DAR (ODAR).
The ODAR, described in this topic, is provided as an
example.
A door, incorporated in the front panel of the ODAR,
gives quick access to the optical disk.
A front panel control/display system, comprising four
pushbutton switches and two 8-character alphanumeric
displays, permits direct user configuration, status
monitoring and command entry.
The following annunciators are provided on the front
panel:
- POWER ON: A green lamp which indicates the
presence of a power supply.
- FAIL: A red LED which indicates ODAR failure.
- MAINTENANCE: A yellow LED which indicates ODAR
performance degradation.
- LOW CAPACITY: A yellow LED which indicates
if the amount of free disk space remaining
is below the defined threshold value.
