The Alta Data Technologies PCIE4L-1553-4F-AT is a multi-channel interface card for PCI Express 4-lane systems, delivering independent, dual-redundant MIL-STD-1553 communication with 1 to 4 channels. Each channel includes 1 Mbyte of onboard memory and leverages the AltaCore™ FPGA protocol engine paired with AltaAPI™ software—a multi-layer architecture supporting ANSI C and Windows .NET (MSVS 2005/08/10 C++, C#, VB.NET). The card operates as a 1/2 size, PCI Express 1.1 interface and complies fully with MIL-STD-1553B Notice II/IV, MIL-STD-1760, 1553A, and Link-16 standards.
