Part# Description
NHi-15515PCI** Half Sized PCI 1553 Test Card.
NHi-15530ISA** ISA 1553 Test Card with Validation Test Software.

Special Note:

The NHi-15530 is form/fit and functionally identical to the DDC P/N BUS 65518 and the NHi-15515 is form/fit and functionally identical to the DDC P/N BUS 65547 with the advantage of the NHi boards being half size.


These Cards can be used as a software development tool for NHi terminals or for Bus simulation and testing. When used as a software development tool, application software can be created faster and more efficiently.
