Abaco Systems / Condor Engineering CEI520A-1616P ARINC Interface for PCI

The Abaco Systems / Condor Engineering CEI520A-1616P is a PCI bus ARINC interface card delivering multi-protocol avionics databus connectivity. It supports 16 independent receive and 16 independent transmit ARINC 429 channels operating at 12.5 KHz or 100 KHz data rates, plus 16 input and 16 output avionics-level discretes. The card integrates on-board message scheduling, label filtering, multiple buffering, time-tagging, and error injection/detection on a single high-performance processor platform. Input discretes accept TTL to avionics voltage conversion; output discretes switch up to 0.5 ampere. Signal levels are programmable across a wide range, with receive thresholds from ±0.1 to ±13.5 VDC (A to B) and transmit outputs from 0 to ±10 VDC (A to B). The CEI520A variant supports universal PCI signaling (3.3V or 5V); the CEI-520 model operates at 5V only. Beyond ARINC 429 and 717, the interface handles ARINC 419, 561, 571, 573, 575, 582, and CSDB protocols. Parity support includes odd, even, or none, with parity error reporting. Fully independent channel operation delivers maximum simultaneous throughput across all channels. Connectors include 68-pin receptacle (SCSI-3 compatible) for databus and 50-pin IDC-style for discrete I/O.
