CRDI USB

CONTINUOUS RESPONSE DIGITAL INTERFACE

    NOTE: This model is no longer available.

  The interface plugs into any standard USB port available on today's computers (including laptop/notebook), and no complicated hardware installation is necessary.  

         
  The dial connector is compatible with the original CRDI interface so that the dials you already own can be used with no modifications.

Up to 8 dials can be connected at the same time.

 

       

 

  The CRDI USB hardware is based on a microprocessor that incorporates most key circuitries such as A/D conversion, USB communications on a single chip.  With its low power requirement it can operate under the power available on USB connection, and no external power connection is needed.

The firmware (program that is stored on the microprocessor chip), printed circuit board (PCB) and enclosure have been custom designed, fabricated and hand-assembled at CMR.
