Digital Output: Timed
A digital output in timed mode will send a pulse train with specified parameters.
The signal can be configured by setting frequency and duty cycle, or samples
high and low.
Frequency (Hz)
: The number of pulses per second.
Duty Cycle
: The percentage of time a pulse train is high.
Samples High
: Number of 30kHz sample periods output should be held high.
Samples Low
: Number of 30kHz sample periods output should be held low.
Offset (mV)
: DC offset voltage of the digital output.
Digital Output: Triggered
A digital output in triggered mode will send a pulse when the selected trigger
stimulus occurs.
Digital Input Rising Edge
: Waveform triggers when a user defined digital input
pin transitions from low to high. A digital input bit must be selected.
Digital Input Falling Edge
: Waveform triggers when a user defined digital input
pin transitions from high to low. A digital input bit must be selected.
Spike Unit
: Waveform triggers when a sorted unit is detected on a defined
channel.
NeuroMotive ROI
: Waveform triggers when a subject enters or exits a region of
interest.
Extension
: Waveform triggers based on custom extension code loaded onto
hardware.
Serial I/O
The Serial I/O Properties window
displays the serial communication
parameters and allows the user to
name and enable the serial port.
Serial communication parameters
cannot be changed.
