NEMbox / NIMbox Programmable NIM Module

NEMbox (Nuclear Electronics Miniature Box) is a programmable Logic / DAQ module, powered either in a NIM crate (NIMbox version) or with a commercial 6V output AC/DC transformer ("Desk" version). It is well suited for scientific and educational purposes.

NEMbox and NIMbox consist of a FPGA main carrier board with USB-2 interface and up to 4 I/O Sub-modules. A firmware programmed into the FPGA as well as interface software featuring "LogicPool", provides a new and unique way for the user to build up his specific setup by using prebuilt functional modules and to wire them internally for his application.

A user defined internal wiring configuration can be saved on an EPROM chip so that the module does not need to be reprogrammed in case of power failure or system reset. All communication with the module as well as programming is done via a USB-2 interface.

Being able to work as multiple coincidence, fan in / fan out, splitter, logic, discriminator, ADC, TDC, etc., NEMbox/NIMbox finds many applications in trigger logic and data acquisition, and allows to cut costs because one single unit can replace the functionality of several non programmable NIM modules.
