Designed to meet the extensive data monitoring requirements of modern digital aircraft, the iDMU is Teledyne's new-generation Data Management Unit. Integrating the latest microcomputer technology, the iDMU delivers increased performance, while significantly reducing the circuit card count, which results in higher reliability and lower maintenance costs.

Multi-Function Unit
Teledyne's iDMU combines multiple functions into a single unit, allowing operators to reduce weight and power consumption. The unit integrates a data recording function via PC Card media for QAR/DAR and message data recording. Its enhanced ACMS (Aircraft Condition Monitoring System) function supports higher-capacity and faster data throughput, therefore facilitating both aircraft/engine performance monitoring, as well as advanced monitoring of daily flight operations.

Ethernet Enabled
The iDMU features an Ethernet connector which permits high speed data transfer to/from other Ethernet enabled systems. This facilitates data transmission within an airline's operations, therefore promoting initiatives for a "Connected Aircraft".

Flexible ACMS Capability
Like all other Teledyne airborne avionics systems, the iDMU is fully user-programmable via Teledyne's MS Windows-based Application Generation Software (AGS). This software tool allows operators to easily customize the various elements of their ACMS applications, such as QAR/DAR output data maps, MCDU screens and enhanced ACMS reports.

Teledyne's iDMU is certified on the Boeing 747-400 and 767-300 aircraft and is available for both retrofit and forward fit installations. The iDMU is also standard equipment on the 747-8, co-labeled and provided under sub-contract through Rockwell Collins.

iDMU Hardware Description
The iDMU is comprised of six major assemblies:
*AMP3: The AMP3 receives data from external aircraft systems via ARINC 429 broadcast busses and discrete inputs. The ACMS generates reports based on specific triggering conditions in the aircraft data. It provides data recording capabilities to QAR/DAR (internal PCMCIA card or external) and programmable reporting functions. The AMP3 also establishes communication with several external devices via dedicated ARINC 429 busses for the purposes of transferring reports, message or display information.
*APX3: Comprised of the PCMCIA connector, the PCMCIA interface chip, and the Ethernet interface chip. It provides recording of raw and message data.
*Power Supply: The iDMU power supply operates from the aircraft's 115 VAC 400Hz single-phase power. The power supply is capable of tolerating an up to 200-millisecond power interrupt without any adverse operation and transparent to the software. A power interrupt greater than 1000-milliseconds will cause a cold start and an interrupt between 200 and 1000 milliseconds will cause either a warm or cold start. Power Consumption: Less than 32 Watts.
*Motherboard provides interface between the AMP3 processor, the power supply, and the ARINC connector card.
*ARINC connector card provides interface between the motherboard and the Input/Output signals. Connector: ARINC 600 Standard
*Enclosure: 6 MCU , Weight: < 12 lbs
