NHi-158xx Terminal+ Series

The Terminal+ is a complete Multi-Protocol Mil-Std-1553 Data Bus Interface between a dual redundant bus and a host processor. The device functions as a programmable Bus Controller, Remote Terminal, Bus Monitor and simultaneous Monitor/Remote Terminal. It contains a protocol chip, two monolithic transceivers and 64K word SRAM and two integrated transformers.  The only external component required is a 20MHz clock.

The Terminal+ appears to the host computer as 64K words of 16 bit wide memory controlled by standard RAM signals. The device can thus be easily interfaced with all popular processors and buses. The built in interrupt controller supports an internal FIFO which retains header information for queuing up to 6 pending interrupt requests plus an overflow interrupt.

All modes of operation access data tables via pointers residing in RAM which facilitates multiple buffering. This allows buffers to change without moving data and promotes efficient use of RAM space. The data tables have programmable sizes and locations. The Terminal+ defaults to remote terminal operation on power up.
