The Abaco Systems / GE RAR-PCIE-1616 is a high-density PCI Express interface card delivering ARINC databus functionality for aerospace simulation and testing. Operating over native 4-lane PCIe, it supports up to 32 ARINC 429 channels (16 Rx / 16 Tx), ARINC 717/573 dual-mode operation with Harvard Bi-Phase and Bi-Polar Return to Zero encoding, and ARINC 575 plus selected 2-wire 32-bit protocols. The card provides 2 MBytes of onboard RAM for transmit and receive buffering with three distinct modes—buffered (per-channel circular buffers), merged (time-sequenced single buffer), and dedicated (latest-data snapshot). Independent, software-programmable bit rates span all channels with simultaneous maximum data throughput. Discrete I/O comprises 16 input and 16 output channels supporting avionics-level and TTL voltages with open-collector/open-drain outputs. Additional capabilities include message scheduling, label filtering with SDI and promiscuous modes, time-tagging, error detection and injection, automatic transmit slew rate control, and onboard temperature and voltage monitoring. Optional IRIG-B receiver (AM or DC/TTL) and generator (DC/TTL) enable external time synchronization across multiple boards. Conformal coating is available. The standard-height, half-length form factor (4.376 x 5.0 inches) integrates into compact avionic test systems via an advanced high-level API.
