OmniBus® cPCI Interface for Serial

Description

Ballard's OmniBus products connect computers or networks to one or more avionics databuses or other interfaces. OmniBus Serial refers to RS-422, RS-232, and RS-423 serial 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 offload the host or for stand-alone operation. Each module has its own DSP dedicated to protocol processing.

OmniBus Serial products are used to interface with equipment using RS-422, RS-232, and RS-423 asynchronous communications. OmniBus Serial modules have four independent universal asynchronous receiver transmitters (UARTs), each having one transmitter and one receiver. A combination of software programming and connection wiring configures each port for balanced RS-422 or for unbalanced RS-232 or RS-423. User software controls the baud rate, word encoding, and other parameters. Each transmitter and receiver has a large 4 Kbyte FIFO with a programmable threshold for event triggering. Software can interact with the interface through polling or interrupts. The OmniBus Serial page contains complete information on serial functionality for OmniBus products.

ARINC 429 channels may be combined with OmniBus Serial ports on the same module. Applications for OmniBus products include testing, simulation, and operational uses of avionics databuses. The high channel count, multi-terminal 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.

Software

The easiest way to operate an OmniBus cPCI card is with Ballard's CoPilot software running on a Windows computer. CoPilot is an intuitive, interactive program that simplifies the simulation and testing of avionics systems. CoPilot may be purchased separately or bundled with OmniBus hardware.

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.

Windows 95/98/NT/Me/2000/XP drivers are included. An SDK is available for advanced users to develop applications for the PowerPC. Contact Ballard for availability of drivers for other operating systems (Linux, VxWorks®, etc.).
