Modular Acquisition Unit ANALOG AND DIGITAL DATA ACQUISITION AND PROCESSING FOR AIRCRAFT APPLICATIONS

The MAU is an easily customizable data acquisition system designed for extremely harsh environments that gathers aircraft data to be transferred to a Flight Data Recorder (FDR) or other avionics systems on an aircraft. It is able to capture ARINC 429, ARINC 717 and MIL-STD-1553 digital data, as well as analog and discrete sensor inputs including synchros and LVDTs. The MAU provides 24 channels in the base module with 24 additional channels per expansion module. RS-422 data can also be acquired on an aircraft-specific basis.

The MAU’s rugged aluminum flange-mount housing, along with MIL-DTL-38999 connectors, provides an environmentally-sealed enclosure that can be mounted in any attitude and is ideal for most operational settings. This includes both commercial and military fixed-wing and rotarywing aircraft. Because of its small size the MAU can be readily mounted on the airframe and does not require a pressurized location.

Expansion of the MAU’s capabilities includes the following modules:

• Expanded Data Acquisition with ARINC 717 and 429 output − ARINC 717, ARINC 429 and MIL-STD-1553 inputs − Analog/Discrete inputs

• Pneumatic (Pitot-Static)

• Quick Access Recorder (QAR)

• GPS Splitter & Receiver Unit

• Emergency Locator Transmitter

• Wireless Data Transfer

• Available 4.3-inch EMI-shielded touch screen LCD with optional NVG Class A capability
