Lx429-5 ARINC 429/717 PCI/PCIe Interface

The LP429-5 (PCI) and LE429-5 (PCIe) are personal computer expansion cards for communicating with ARINC 429 and ARINC 717 systems. These feature-rich interfaces provide programmable dual redundant data buffers and deep built-in memory. Avionics discretes can be used as general purpose I/O or linked in hardware to databus activity as triggers or syncs.


The Lx429-5 products support maximum data throughput on all avionics interfaces. Each channel is independently configurable for high or low speed operation. Messages can be captured by a sequential monitor for all channels, or via individual message monitoring. Notification of databus activity is handled through the on-board Event Log, which can be processed by polling or via an interrupt. To dramatically reduce the host CPU processing, the sequential monitor has a DMA mode that automatically moves records to host memory through PCI/PCIe bus mastering.
