The BU-65549 1553 PCI card provides full, intelligent interfacing between a PCI bus and one or two independent dual redundant MIL-STD-1553B Data Buses. Software controls the operation of each channel as either a 1553 Bus Controller (BC), 1553 Remote Terminal (RT), or 1553 Bus Monitor (MT).
The 1553 PCI board features DDC's Mini-ACE® Plus hybrids. As such, each channel includes dual 1553 transceivers and encoders/decoders, complete 1553B protocol, 64K words of shared RAM and memory management logic for all three modes. Background Mode Operation prevents inadvertent access to the card during power-on self-test.
On-board Interrupt Mask and Interrupt Status Registers support flexible operation for both interrupt and polling applications. The memory management scheme for RT mode provides an option for separation of broadcast data plus a circular buffer option for individual RT subaddresses to offload the PC host CPU.
Additional features include a wrap-around Built-In-Test, register programmable interrupt level, software programmable RT address selection and a free “C” software subroutine library. Its full compliance with MIL-STD-1553A and B makes it an excellent choice for real-time simulation, test, and system integration applications.
