NameDescription                              ConstraintsTypeOn
Port Settings
Line Number        Defines a zero-based index of the selected line of the NI digital port                Int32         
Port Name        Selected port on the NI board                String         
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.                stPara..         
Signal Profile        Defines the time-amplitude profile of the output signal.'Level Change', 'Pulse' and 'TTL' profiles are available                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.                Double         
Pulse Duration        Duration of a single output pulse in ms. The value is applied only if the Pulse signal profile is selected                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                clTime         
Pulse Number        Defines a number of pulses in the pulse train. The value is applied only if the Pulse signal profile is selected                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;                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.                Boolean         
Is Enabled        If set to false the element is completely omitted when the experiment is run                Boolean         
Title        Title of the element                String         

NI Digital Line Element allows sending output via a selected line on the digital port.
