ARINC 429 USB Databus Interface
Ballard Technologyâ€™s BUSBoxâ„˘ is a family of versatile avionics databus interfaces. Through a BUSBox, any computer with a USB or RS-232 serial port can communicate over or monitor an avionics databus. A family of over forty BUSBox models support a variety of avionics protocols and provide many functionality options.
CoPilotâ„˘, an interactive graphical user interface, or an application-specific software program may be used to control the BUSBox. A BUSBox can support one or more military and commercial avionics databus protocols. Multi-protocol BUSBoxes provide savings and simplicity over using separate interfaces for each protocol. A BUSBox may be upgraded later with additional channels or capabilities. Though the BUSBox is normally controlled through a USB or serial port, custom models are available for stand-alone operation as data converters.
The BUSBox offers many advantages over alternative avionics databus interfaces. It is plug-and-play and may be installed without opening or even powering down the computer, making it easy to share and move around between different portable and desktop computers. Using inexpensive USB hubs and BUSBoxes, a single computer can communicate with or monitor an unlimited number of avionics databuses. The BUSBox is small and can sit conveniently on the desktop, tucked away out of sight, or be mounted in various ways.
Custom gate arrays and a powerful Digital Signal Processor (DSP) the BUSBox handle the avionics databus protocol without host intervention. The large on-board memory and flexible message buffering schemes ensure data integrity.
