The Abaco Systems RAR-PCIE-88 is a high-density PCI Express interface board for ARINC avionics databus applications. It connects and manages ARINC 429, ARINC 575, ARINC 573, and ARINC 717 protocols, plus selected 2-wire 32-bit standards, over native 4-lane PCIe. Purpose-built for simulation and test environments, it delivers comprehensive multi-protocol databus functionality with flexible channel configurations and dual-mode modulation support.

Technical Specifications

• Interface: Native 4-lane PCI Express (PCIe)
• ARINC Channels: Up to 16 Receive and 16 Transmit ARINC 429 channels; configurations support combinations with ARINC 717/573 Dual-Mode functionality
• Dual-Mode Functionality: Programmatically selectable Harvard Bi-Phase (HBP) or Bi-Polar Return to Zero (BPRZ) encoding across multiple bit rates and subframe combinations for ARINC 717/573
• On-Board RAM: 2 MBytes for transmit and receive data buffers
• Data Rates: Independent, software-programmable rates per channel
• Transmit Buffering: Scheduled and Burst Mode (FIFO) on all ARINC 429 Tx channels
• Receive Buffering: Dedicated Mode (latest-data snapshot), Buffered Mode (per-channel circular buffer), or Merged Mode (time-sequenced single circular buffer)
• Discrete I/O: 16 inputs and 16 outputs; TTL-to-avionics voltage support; open-collector outputs
• Temperature & Voltage Monitoring: On-board sensors included
• Transmit Slew Rate: Automatic adjustment capability
• Error Handling: Detection and optional injection capabilities
• IRIG-B Support: Optional Receiver/Generator for AM or DC/TTL synchronization across multiple boards
