Properties ¶

Name	Description	Constraints	Type
Port Settings
Analog Port	Selected port on the NI board	Design Time..	String
Sample Rate	Define a analog sampling rate in number of samples per second	Design Time..	Double
Working Mode	Defines a working mode for the element.Select the 'AutoOutput on event onset' mode for sending signals synchronously with an onset of the parent event,or 'Triggering on input' mode for catching the particular pattern in port input. For custom reading/writing scenarios use the 'Manual IO' mode, in which port communication can be controlled by your code.	Design Time..	stPara..
DAQ settings
Voltage Range	Defines the voltage range (in volts) for the port output. The chosen range must be supported by the NI board, otherwise the port communications will fail. The standard range is 0..5	Normal..	clRange
Output
Signal Profile	Defines the time-amplitude profile of the output signal.'Level Change', 'Pulse' and 'TTL' profiles are available	Design Time..	stPara..
Preface Duration	Defines the duration (ms) of the guarantied zero preface interval for the TTL or Pulse signals. Increase the preface duration marginally, if your recording hardware does not detect port signals. Note that a non-zero preface delays the onset of the actual signal.	Normal..	Double
Pulse Duration	Duration of a single output pulse in ms. The value is applied only if the Pulse signal profile is selected	Normal..	UInt64
Interpulse Duration	Defines a duration of the inter-pulse interval in ms. The value is applied only if the Pulse signal profile is selected	Normal..	clTime
Pulse Number	Defines a number of pulses in the pulse train. The value is applied only if the Pulse signal profile is selected	Normal..	Int32
Output Value	Value to be sent through the port. Can be defined in integer or binary format, e.g. Output='01010000'; or Output=255;	Normal..	clBina..
Send Output Now	Runtime action initiating an instant output communication through the port. Call this action in snippets by 'SendNow=true;', but only if the element works in the 'Manual I/O' mode.	Runtime Command..	Boolean
Control
Is Enabled	If set to false the element is completely omitted when the experiment is run	Design Time..	Boolean
Title	Title of the element	Design Time..	String

NI Analog Port Element allows sending signals via the analog ports on the National Instruments DAQ cards. The element can be used for triggering external hardware, which is connected to the DAQ card. Note that this element does not support reading the analog input (the Input Listener mode).
