OVERVIEW
DDC’s Avionics Interface Computer (AIC), (or as it’s known by its part number BU-
67121Wx)
is a development system for lab and production test applications which
provides a scalable, programmable, and portable platform to develop and test MIL-
STD-1553 and ARINC 429 system applications via an Ethernet network. By utilizing
the Ethernet network with the AIC’s Remote Access or Protocol Conversion modes
eliminates the need and cost of long cabling/write runs from the test lab to the
onboard 1553/429 interface under test. The AIC’s use of a Linux OS provides the
ability to customize the AIC as it allows for the integration of DDC line of cards as
well as 3
rd
party PMC and PCIe cards.
The AIC comes with Fedora Core 20 installed on its Solid State Drive and has an
Intel
®
Q7 Processor and 2 GB of DDR3L SDRAM, which enables the AIC to serve a
broad range of data conversion and unique application needs. The AIC includes one
10/100/1000 Ethernet channel, two USB 2.0 ports, one RS-232 port, and one VGA
port. The AIC operates over an ambient air temperature range of 0°C to +55
°
C, and
includes an internal fan.
The AIC has two PMC and two mini PCIe sites providing hardware flexibility for
additional hardware components such MIL-STD-1553, ARINC 429, ARINC 717,
Avionics and Discrete I/O, AFDX and many other configurations. For other
configurations not mentioned, please see the Configuration Options or Ordering
Information sections for additional details on customizing the AIC. Please also
contact the factory with custom requirements that is not seen on the ordering
information tables.
The AIC offers a high degree of flexibility, and is therefore suitable for a wide range of
lab applications. The AIC has three modes of operation Remote Access Mode,
Protocol Conversion Mode and Stand Alone Mode.
In Protocol Conversion Mode, the AIC is configured to provide autonomous
communication from any input channel(s) to any other channel(s). To minimize setup
time and provide turnkey operation, the AIC includes a high-level protocol conversion
API. Alternatively, users may develop their own conversion applications by means of
DDC’s AceXtreme MIL-STD-1553 and/or ARINC 429 APIs, along with Linux TCP/IP
and UDP/IP socket interfaces for the AIC’s Ethernet channel.
In Remote Access Mode, users are able to develop applications running on a remote
computer communicating over Ethernet to the AIC’s MIL-STD-1553 and/or ARINC
429 channels. In the remote access configuration, the user is able to write
applications running on a remote host invoking the AceXtreme MIL-STD-1553 and/or
ARINC 429 APIs. As an alternative to developing application software, in Remote
