CogniScan DAC

The CogniScan model 14000 Digital to Analog converter is a high quality 8 bit DAC specifically developed to be used with the CogniScan EEG Data Acquisition System. The device is designed to interface to a stimulus presentation computer for data marking purposes during EEG/ERP experiments. The precision device is controlled via a standard parallel printer port.
Features
  • Compatible with many Stimulus Presentation Software packages.
  • Single port output instruction sets output level.
  • 8 bit resolution
  • Fast settling time
  • Uses standard parallel printer port while allowing a printer to share the same port
  • Current limiting output with short circuit protection
  • Configurable analog output voltage ranges such as: -10 to 10 V, -5 to 5 V, 0 to 5V (Standard), 0 to 10V
