MAUModular Acquisition Unit
LIGHT WEIGHT AND COMPACT DATA
ACQUISITION AND PROCESSING.
The Modular Acquisition Unit (MAU) is a small, flexible, flange-mount line replace-
able unit developed for both analog and digital signal acquisition, processing and
recording applications.
Traditionally, these applications have been to support EUROCAE ED-112 crash
data recording systems, however the technology is very versatile and can be em-
ployed in other forms of data acquisition and processing.

TECHNICAL SPECIFICATIONS
Modular designThe MAU is a stackable ‘modular’ plat-
form which allows easy customisation
for specific aerospace applications.
Each module has a fixed footprint of
3.5 inch (90 mm) width and 3.2 inch (80
mm) depth.
The MAU modules perform functions
such as:
▶ Expanded signal acquisition capa-
bility (24 channels per module).
▶ Quick Access Data Recorder (QAR).
▶ Pitot-static pneumatic inputs.
▶ Wireless data transfer.
