The Rockwell Collins Maintenance Access Terminal provides the human-machine interface for the on-board airplane maintenance system.

The MAT-2000 system consists of a Maintenance Access Terminal (MAT-2000), Keyboard Unit (KBU-950), Hard Disk Drive (HDD-2000) and the Operational Program Software (OPS-2000). This architecture offers significant weight, space and power savings compared to previous systems.

Hardware:

Maintenance Access Terminal (MAT-2000) - The Maintenance Access Terminal is the system unit that contains the LCD display, main graphics, BITE computer processors, Ethernet connections, nonvolatile and dynamic memories, compact disk and floppy disk drives, cursor control trackball and power supply. The MAT-2000 is a line replaceable unit.

Hard Disk Drive (HDD-2000) - The Hard Disk Drive module is a 320MB (minimum) formatted hard drive. HDD-2000 is a line replaceable module.

Keyboard Unit (KBU-950) - The Keyboard Unit provides operator input into the MAT workstation. KBU-950 connects directly to the aircraft wiring.

Software:

Operational Program Software - Operational Program Software is an open system software environment that enables the MAT hardware to serve as an interface to maintenance applications. OPS-2000 provides the operating system and Windows functions for the MAT system through a graphical user interface on a real-time operating system. Functions include Main Menu, Self Data Load and BITE. The OPS-2000 is distributed on diskette and is preinstalled on the MAT-2000.
