Over the past two decades, it has become increasingly evident that researchers require a convenient method of connecting various signals into their computers for simultaneous data acquisition. For this purpose, Noraxon developed the NorBNC connector system. Its primary use is to aid the research professional in interfacing multiple modality instrumentation signals with a single computer. Previously, at most research locations, crude "home grown" wiring harnesses were assembled on an 'ad hoc' basis in an attempt to satisfy this function. NorBNC provides a more practical approach.

NorBNC provides 19 connectors on one main assembly: • Sixteen (16) BNC connectors correspond with each of the 16 channels normally found on most Analog to Digital converters; • One (1) 25 pin D-sub connector is to be used for easy multiple channel input to the board, and; • One (1) 26 pin IDC ribbon style header is provided to be used as an output from the unit. There is also a two-position switch located beside each of the BNC connectors. Each switch is provided as an enabled or disabled function for the adjacent BNC connector.
