Displays designed for rotary and fixed-wing airborne applications with proven interface capabilities will be demonstrated by Industrial Electronic Engineers (IEE) at the Army Aviation Missions Solutions Summit (Quad A) in Nashville (April 14-16). The rugged display supplier will feature both the 4.3in. and 3.5in. CDU’s as cost effective solutions.

“IEE’s products focus on supporting Open System Architecture (OSA) through a suite of communication interfaces and video processing capabilities,” commented Steve Motter, Vice President of Business Development for IEE. “This includes everything from traditional avionics busses, to ARINC 818, to Ethernet based video distribution architectures such as ARINC 661."

OSA allows for interoperability through the use of standard interfaces. Implemented with controlled Linux OS releases and board support software, this family of CDU’s supports a wide range of Avionics architecture applications. Ease of installation is supported by standard dzus rail mounts and mil-spec I/O connectors.

The 4.3in. Control Display Unit (CDU) can be used in a variety of applications for air or ground vehicles. Typical applications include control of radio communications and configuration of aircraft systems.

This smart display utilises an Intel Atom E3825 dual core processor, and operates under a wide range of lighting conditions from full dark (NVIS) to bright sunlight. The assembly consists of a Line Replaceable Unit (LRU) with a 4.3in. diagonal viewing screen and a QWVGA (480x272) pixel resolution. The rugged aluminium chassis is painted black with white nomenclature.

The display features a contrast Ratio of 1000:1 (native), a Dual Core Intel Atom E3825 processor (1.33 GHz) and 2GB DDR3 SDRAM, 8GB SD Flash. Operating Temperature is -40ºC to +71ºC continuous.

IEE will also feature a 3.5in. Aircraft Control Display Unit (CDU) designed for helicopter avionics. Applied beyond typical radio and communications applications, this CDU provides a central data entry and status display for the Search and Rescue rotorcraft platform’s Personal Locator System (PLS).

The transflective display operates under a wide range of lighting conditions from full dark (NVIS) through bright sunlight. This smart display can control multiple devices and features an ARM 8 processor and interface built around four user defined bezel keys and two rotary selector knobs.

This display boasts a Contrast Ratio: 400:1 (native) and is based on a Texas Instruments ARM Cortex-A8 DaVinci DM3730 System on Module (800 MHz). It has 256MB SDRAM, 512MB NAND Flash, 8GB SD Flash, three USB 2.0 ports, two RS-422 serial ports, and two programmable discrete interfaces. Controls are five sealed push-buttons, one brightness knob, and 1 dual-concentric knob.
