AB1000 Avionics Computers

AB1000 Series - Avionics I/O Computers

Small problem-solver

The AB1000 is a small, lightweight embedded computer with built-in interfaces for avionics databuses and a variety of standard I/O types. Under the direction of its application specific software, the AB1000 can autonomously perform tasks that involve receiving information from some interfaces and processing and mapping the information into other interfaces.

Available Interfaces

  • MIL-STD-1553
  • ARINC 429/575
  • RS-232/422/485
  • RS-232/422/485
  • Ethernet (10/100)
  • USB 2.0 Host (High Speed)
  • CompactFlash® disk
  • Discrete I/O

Flexibility For A Variety of Applications

The flexibility of the AB1000 Series (also called the Avionics BusBox 1000 or simply Ballard Box) is a small form factor system that lends itself to many different applications. As a protocol converter, the AB1000 can aid in the integration of commercial and military avionics. For example, acting as a MIL-STD-1553 Bus Monitor and an ARINC 429 transmitter, the AB1000 could make navigation data from a military system available to a commercial device. The Ethernet port may be used in a variety of applications including an Ethernet-to-avionics bridge, an avionics data server, or a remote control/monitoring interface for avionics devices. Aircraft data can be monitored and recorded to the on-board CompactFlash disk. This is useful in maintenance applications where flight data can subsequently be analyzed to detect potential problems.


  • Protocol converter
  • Data server (Ethernet)
  • Data recorder
  • Remote monitoring


At the heart of the AB1000 Series is a user programmable PowerPC® processor, which controls the various standard (serial, Ethernet, and USB) and avionics databus (MIL-STD-1553, ARINC 429/708, etc.) interfaces. The high level of functionality implemented in the hardware interface circuitry gives the software application full use of the PowerPC processor.

Additional Features

The USB host port allows for the connection of a wide variety of devices. For example, a USB mass storage device could be used for transferring data to/from the AB1000 Series, or an 802.11 wireless device could be attached as an alternative to the wired Ethernet port. Also included are serial ports and avionics level discrete I/O which can be used to interface with other devices.

Embedded or Tethered Operation

There are two ways software can operate the AB1000, either embedded or tethered. Embedded programs are typically first developed on a host computer and then uploaded to the AB1000's universal BTIDriver non-volatile solid-state storage. At power-on the embedded application boots and runs without host intervention. The tethered case is where a separate computer runs the application and controls the AB1000 over Ethernet.
