AB2000 Avionics Computers

AB2000 Series - Avionics I/O Computers

An Embedded Computer and So Much More

With so many built-in capabilities, the highly-flexible AB2000 family is the ideal fit for a wide range of applications. These rugged, conduction-cooled, COTS devices combine a powerful computer processor, multi-protocol databus interfaces, Ethernet, USB, other I/O, and PMC expansion in a small, lightweight package.

Multiple Databus Protocols

Avionics databus protocols are not an add-on with the AB2000. Choose the model that includes one or multiple protocols built right in to meet the unique needs of your application. Powerful interface circuitry manages protocol functions so the AB2000's processor is free to concentrate on your software application.

Available interfaces include:

  • MIL-STD-1553
  • ARINC 429/575
  • ARINC 708/453
  • ARINC 717/573
  • RS-232/422/485
  • Ethernet (10/100)
  • USB 2.0 Host (High Speed)
  • Flash Storage
  • Discrete I/O
  • PMC Expansion

PMC Expansion

The AB2000 has an internal PMC site that can be populated to adapt the functionality of the device to applications requiring other types of I/O, additional channels, or special capabilities. These Factory-installed PMC cards allow you to add additional I/O and functionality such as Ethernet switch, relays, synchronous serial, CAN bus, and more.

Powerful Application Solutions

The AB2000 Series delivers outstanding performance on the ground and in the air. They are routinely deployed on helicopter, fixed wing, and ground mobile platforms in applications that include:

  • Data and protocol converter
  • Network server
  • Health monitor
  • Local/distributed control
  • Electronic Flight Bag (EFB) integration
  • Maintenance gateway
  • Data recorder
  • Ethernet switch

Embedded or Tethered Operation

There are two ways software can operate the AB2000, either embedded or tethered. Embedded programs are typically first developed on a host computer and then uploaded to the AB2000'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 AB2000 over Ethernet.
