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 Ballard's optional CoPilot software. CoPilot provides powerful, easy-to-use interactive tools for databus test, analysis, and simulation. See "Software" tab for more information.

The easiest way to use the MIL-STD-1553 functionality of your USB 1553 device is with CoPilot, Ballard's Windows-based software. CoPilot is an intuitive, interactive program that simplifies the testing and simulation of MIL-STD-1553 systems. In CoPilot, you can simulate the Bus Controller, up to 32 RTs, and monitor, record, and export bus activity. Data can be entered and displayed in engineering units and data definitions may be saved to the 1553 database. CoPilot features include virtual instruments, strip charts, moving map displays, scripting, and software playback mode. CoPilot also supports ARINC 429, ARINC 708, ARINC 717, ARINC 664/AFDX® protocols, and serial. You can add CoPilot at anytime. However, you will receive a discount when you purchase CoPilot bundled with the hardware.

Users can develop their own software applications with the included BTIDriver API:

  • With only a few function calls, a program can operate the USB hardware and process messages to and from the avionics databuses.
  • Functions include routines for transmitting, receiving, scheduling, recording, time-tagging, and manipulating data.
  • With BTIDriver, application code migrates seamlessly to and from other Ballard devices, reducing development time and costs.
  • A translation DLL is included to easily import applications from legacy Ballard products that are not compatible with BTIDriver.
