LP429-5 (PCI) / LE429-5 (PCI Express)
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. Models offer 4 to 32 ARINC 429 channels, and up to 4 ARINC 717 channels, 16 input/output avionics level discretes, and IRIG time synchronization/generation. 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.
