Multi-Protocol Mil-Std-Data Bus Interface
Model #
NHI-156XXET
The NHi Ceramic family of Mil-Std-1553
terminals address the requirements for
small, cost effective, reliable terminals
suitable for critical military applications.
The Ceramic family is designed as an
autonomous interface between a host
processor and the terminal that unbur-
dens the CPU. The ET versions function
as a programmable BC/RT/MT or simul-
taneous MT/RT. The RT devices operate
as Remote Terminal only.
