The Abaco Systems / Condor Engineering CEI520-22 is a PCI bus interface card providing ARINC 429 and ARINC 717 connectivity for aerospace and defense databus applications. Built around an Intel 80960 processor, it delivers message scheduling, label filtering, multi-mode buffering, time-tagging, and error detection. The card supports up to 16 receive and 16 transmit ARINC 429 channels at 12.5 kHz or 100 kHz data rates, with configurable input thresholds (±0.1 to ±13.5 VDC) and adjustable transmit voltages (0 to ±10 VDC). Additional protocol support includes ARINC 419, 561, 568, 571, 573, 575, 582, CSDB, and RS-422/423.
