The Mod. N454 is a single width NIM unit housing 4 independent Fan In-Fan Out sections. Each section accepts 4 input NIM signals and performs on these the logic OR function. The result of the function is available as 4 normal and 2 complementary NIM signals on 6 front panel connectors.
The unit can be programmed, via a front panel switch, to work as 4 OR sections (4 inputs/4 outputs) or 2 OR sections (8 inputs / 8 outputs).
