MDU–254
5x4 inch avionics-grade Mission Display Unit
The MDU-254 is an avionics-grade 5x4 inch Mission Display Unit
derived from Barco’s field-proven CHDD family. The MDU-254
has both a digital video input (DVI) and most of the currently
available analog video inputs (composite PAL/NTSC, STANAG
3350, RS343 and/or RGB,...)
Equipped with the latest, sunlight-readable AMLCD technology,
the MDU-254 delivers excellent brightness and contrast values.
Moreover, the use of advanced electronics enables a very
compact footprint (maximum 4.5” depth) and low power
consumption. Because of this, the MDU-254 can be integrated
in virtually any cockpit or cabin environment.
Compatible with FLIR, daylight video cameras, moving maps,
computers and radar, the MDU-254 Display Unit offers a
dedicated imaging solution, wherever your mission takes you.
The unit is DO-178B and DO-254 certified up to level C for the
DVI input.
