NIMbox NPL20

NPL20 – 20 programmable TTL I/O or NIM ports

This single slot wide NIM module is a pre-configured NIMbox version with 4 x SU704 sub-modules. NPL20  has 20 programmable TTL or NIM I/O ports. 

Programming the internal FPGA allows to set-up the ADC channels and their data read out but also to define logic functions for the 20 I/O ports. This includes AND/OR coincidences and majorities fan in / fan out etc. but also include more complex features as timer, counter, and even multi-hit dead-time less Time-to digital converter. All logic functions are programmed into the FPGA via the high speed USB-2 interface.

Using the provided LabView VI library "Toolbox" easy and fast programming of all configurations settings and functions is possible.
