Powerful 1553 Interfaces

The USB 1553 family of pocket-sized USB adapters enable computers to communicate with, simulate, test, and monitor MIL-STD-1553 equipment and systems. These rugged USB 2.0 peripherals feature extensive 1553 functionality and are compatible with virtually all modern PC laptop, desktop, and tablet computers.

These versatile interfaces are suitable for a wide range of applications in the lab and in the field. They support maximum data throughput on all 1553 channels and have a large 32 MB built-in memory. All power necessary for operation is provided via the single USB port. Plug and Play and Hot Swap features make them easy to install and move between computers.


Depending upon the hardware model, each 1553 channel may be either single-function, multi-function, or bus monitor only. Single-function channels can be configured in software as either a Bus Controller (BC), a Bus Monitor (BM), or up to 32 Remote Terminals (RTs). Multi-function channels have protocol error injection capability and can simultaneously be a BC, BM, and up to 32 RTs. All models include eight avionics level input/output discretes and IRIG time synchronization/generation.


Develop software applications with the included BTIDriver API, or use Astronics' optional CoPilot software. CoPilot provides powerful, easy-to-use interactive tools for databus test, analysis, and simulation.
