OmniBus® cPCI Interface for CSDB

Description

Ballard's OmniBus products connect computers or networks to one or more avionics databuses. OmniBus CSDB refers to the Commercial Standard Digital Bus (CSDB) capabilities available for all OmniBus platforms.

OmniBus products are built around an intelligent platform that can host one or more protocol modules. This flexible architecture accommodates mixed protocols, high channel counts, and unsurpassed processing power. An on-board PowerPC processor can be programmed by the user to off-load the host for stand-alone operation. Each module has its own DSP dedicated to protocol processing.

Applications for OmniBus products include testing, simulation, and operational uses of avionics databuses. The high channel count, multi-channel capability, and on-board PowerPC processor provide the power necessary for flight simulators and system integration laboratories. An OmniBus product may also be used as a data server or as a stand-alone converter from one protocol to another.

CSDB Channels

OmniBus CSDB may be used for communicating with and monitoring serial digital avionics equipment including communication and navigation radios. With the addition of ARINC 429 channels, a single OmniBus product can simultaneously communicate with other commercial avionics equipment. OmniBus CSDB may also be used for some general purpose scheduled and asynchronous serial communications.

OmniBus CSDB modules are available with up to 4 receive and 4 transmit (4R/4T) CSDB channels and can be combined with 4 receive and 4 transmit (4R/4T) ARINC 429 channels on the same module. All CSDB receive channels feature independent filtering based on the message label (address byte) and the source identifier field (status byte). Each transmit channel supports continuous, non-continuous, and burst messages. On-board scheduling can accurately maintain message repetition rates.

The OmniBus CSDB page contains complete information on CSDB functionality for OmniBus products.

Software

Users can develop their own software using the included BTIDriver™ API. Although each OmniBus product can be easily configured and run with only a few API calls, the comprehensive library includes a broad range of functions for specialized needs. An SDK is available for advanced users who are developing software to run on the PowerPC.

CompactPCI Systems

MIL-STD-1553, ARINC 429, ARINC 708, ARINC 717, serial, and discrete IO cards are also available through Ballard Technology as part of an integrated OmniBus cPCI system. Every OmniBus CompactPCI system is uniquely configured to meet the requirements of the customer and is tested and certified for immediate use. CoPilot software support is available. Call Ballard Technology for details on single or multi-protocol cPCI systems.
