This module generates a train of TTL pulses (0-5 V square wave). It can be connected to either an analog or digital output channel to trigger external hardware. You should check the voltage range of your DAQ card to make sure that it can handle 0-5 V.
output(0) – “TTL Signal” : TTL output signal in volts
TTL Duration (s): duration of pulse
TTL Pulses (#): number of TTL pulses within a single train
TTL Freq (Hz): frequency of pulses measured between pulse onsets
TTL Delay (s): time to wait between repeated trials of the same train of pulses
Repeat (#): number of times to repeat the stimulus
