The Astronics/Ballard Technology 112-000-000 OmniBus PCI Databus Interface Module is a high-density, modular PCI interface for simulating, monitoring, and testing avionics databuses. Each module integrates its own Digital Signal Processor (DSP) to prevent host processor overload and enable high channel counts with mixed protocol support in a single card.
## Technical Specifications
**Interface & Architecture**
• PCI form factor with modular, reconfigurable design
• On-board PowerPC® processor for independent or off-loaded operation
• User-programmable with non-volatile memory and automatic boot capability
• 48-bit hardware time-tagging at 1 µSec resolution (select models)
**Protocol Support**
• MIL-STD-1553 (up to 4 databuses)
• ARINC 429 (up to 32 databuses)
• ARINC 717 (up to 16 databuses)
• ARINC 708 (up to 8 databuses)
• ARINC 575, ARINC 573, ARINC 453
• RS-232/422/485 serial ports (up to 8)
• Avionics discrete I/O (up to 64), including 16 bidirectional TTL-level discretes
• Custom protocols available upon request
**Timing & Synchronization**
• IRIG time-code circuits for channel, board, and external equipment synchronization
• Internal or external IRIG time sourcing
• Advanced timing: IRIG, 10 MHz, and PPS
**Built-in Test**
• PBIT (Power-On Built-In Test)
• IBIT (Initiated Built-In Test)
• CBIT (Continuous Built-In Test)
## Key Features
• Modular architecture supports protocol and channel count expansion
• Dedicated DSP per module eliminates data loss from host processor saturation
• Space-efficient design reduces computer footprint requirements
• Flexible processing with multiple on-board processors
## Typical Applications
Avionics databus simulation, hardware-in-the-loop testing, multi-protocol monitoring, real-time databus analysis.
## Compatibility & Integration
Works with CoPilot® analysis software and supports Universal BTIDriver™ API for custom application development. Compatible with other Ballard hardware platforms.
