The Abaco Systems CEI520A-1608 is a PCI-based ARINC interface card engineered for avionics simulation, test, and data logging applications. It delivers up to 16 receive and 16 transmit ARINC 429 channels with on-board message scheduling, label filtering, and time-tagging. The card integrates a 100 MHz Intel 80960 processor, 512 KB shared memory, and intelligent buffering to handle maximum data throughput across all channels simultaneously. Beyond ARINC 429, the interface supports ARINC 419, 561, 571, 573, 575, 582, 717, and CSDB protocols. Discrete I/O includes up to 16 avionics-level and TTL/CMOS inputs and 16 outputs rated for 0.5 A sink current each.
