Abaco Systems / Condor Engineering CEI520-88 ARINC Interface for PCI

The Abaco Systems / Condor Engineering CEI520-88 is a PCI bus ARINC interface card that processes avionics databus traffic across up to 16 simultaneous receive and 16 transmit ARINC 429 channels. The card supports multiple avionics protocols including ARINC 717, 419, 561, 571, 573, 575, 582, and CSDB, with dual-mode functionality (HBP or BPRZ) available for ARINC 717/573 configurations. Maximum data throughput flows across all channels simultaneously, backed by intelligent onboard buffering with dedicated and circular buffer modes per receive channel. On-board message scheduling, label filtering, and time-tagging capabilities streamline data acquisition and protocol management. The card includes error injection and detection, avionics-level I/O discretes supporting up to 16 inputs and 16 outputs, and independently programmable bit rates for each channel. Discrete outputs switch up to 0.5 ampere and support TTL-to-avionics voltage conversion with open-collector output flexibility. Optional features include programmable receive level thresholds, adjustable transmit output voltages, IRIG-B receiver/generator synchronization, temperature and voltage monitoring, and ruggedized configurations rated for extended operating temperatures.
