The CM1553-3 is a family of PCMCIA cards for interfacing to MIL-STD-1553 databuses. It provides features and flexibility previously found only on large format expansion cards. This family of eight cards allows a desktop or notebook computer to serve as a Bus Controller, Remote Terminal or Monitor for testing, simulation and development of MIL-STD-1553 avionics systems. The combination of features and upgrade paths make the CM1553-3 an ideal solution for avionics development, test and maintenance activities.

The PCMCIA product family is available in a rugged milled-aluminum Type III case or a smaller Type II case.

Family of products

  • Choose functionality suited to immediate needs
  • Upgrade later as requirements change
  • Ongoing release of features and products
  • Select from several standard configurations and a variety of options
  • Can be customized for special needs
  • Exceptional value

All CM1553-3 models function on a dual redundant MIL-STD-1553 databus without host intervention. All models provide Bus Controller, Remote Terminal, and Monitor operation and support all 1553 message types. Advanced models can simultaneously operate as the BC, Monitor, and any number of RTs, and inject protocol errors selectively. The powerful DSP core of the PCMCIA card offloads 1553 protocol processing from the host PC. The large on-board memory and flexible message buffering schemes ensure data integrity. Polling and interrupt generation are simplified through a generous set of user options.

The easiest way to use the MIL-STD-1553 functionality of your CM1553-3 card 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 664/AFDX® protocols, and serial. CoPilot may be purchased as part of an CM1553-3 system or separately.


Application Program Interface (API)

Alternatively, software developers can use the bundled Application Program Interface (API) that enables quick and easy development of custom applications. The CM1553-3 can be configured for simple terminal emulation using default memory mapping and buffering options with only a few API calls. Although most users will accomplish their tasks with a small number of API functions, the comprehensive library includes a broad range of tools for specialized needs. Driver software is included for Windows. Linux and drivers available.

Supported in many programming languages, including C/C++, C#, VB, VB.NET, and LabVIEW™
