Specifications – DAQ Input

68-pin SCSI connector compatible with many NI-DAQ cards (e.g. PCI-6221)

Cable is not provided

Input voltage range: -10V to 10V on AO0 (X) and AO1 (Y)

Input impedance ~ 16 k

X input: DAQ AO0, Y input: DAQ AO1, HV Enable: DAQ P1.0

For DAQ input option, power is provided from the NIDAQ card, 

and ex5VDC adapter should NOT be plugged in.

The stereo jack and BNC connectors must not be plugged in as 

they bypass the DAQ input voltages.

HV Enable switch for the high voltage supply on the front panel 

may be used, but software control via NIDAQ is recommended 

in this input mode.
