'nozeropad' in openNSx()
Occasionally in Blackrock continuous files, the timestamp of the first datapoint written to the file will be non-zero. By default, when opening files with non-zero first timestamp using the openNSx() function from NPMK, the function will modify the ...
How to Interpret Digital Input Data
Introduction In Raster Plot, Central can visualize digital inputs as separate pins, but the data is not saved as separate channels for each pin. Rather, the state of all sixteen pins makes up a single 16-bit integer value. Additional information can ...
MATLAB Interfaces For Blackrock Microsystems Data Acquisition Systems
Introduction Blackrock has several functions for looking at and interacting with data collected through our neural signal processors. These functions are available for post-recording processing (Neural Processing MATLAB Kit - NPMK) or for interacting ...

How to Interpret and Use Mapfiles
Overview In Central's Hardware Configuration utility, under the 'Location' header is a Bank assignment and a Pin number. Each Bank, which is lettered A to H, has 32 Pins, which are numbered 1-32. The number of Banks multiplied by 32 is your system's ...
Error Light on Front End Amplifier Power Supply
Introduction A power supply in error mode generally indicates a short either in the power pins on the cable or amplifier or damage to internal fuses due to over voltage conditions. The error light indicates the power supply taking a protective action ...
