Astronics / Ballard Technology LP1553-5/2M MIL-STD-1553 PCI Interface Card

The Astronics/Ballard Technology LP1553-5/2M is a PCI interface card that enables avionics databus communication, simulation, testing, and monitoring via MIL-STD-1553. Built on a 5th generation protocol engine with bus mastering architecture, this half-size PCI card delivers multi-channel 1553 capability for demanding aerospace applications. The card supports MIL-STD-1553A/B, 1760, Link-16, and SADL protocols while maintaining compatibility with modern desktop and embedded systems through universal PCI and PCIe interfaces.
