Line State (false) (boolean) line state: The position of this boolean switch controls the
setting or clearing of the line (or bit) at the port. If the line state switch is slid down to the
off (or false) position the line is cleared. If the line state switch is slid up to the on (or
true) position the line is set.

error in (no error) Error in describes error conditions occurring before this VI executes.
This cluster defaults to no error.

error out Error out contains error information. If the error in cluster indicated an error,
the error out cluster contains the same information. Otherwise, error out describes the
error status of this VI.

ADAC (DIO) Start Device

This VI starts digital I/O acquisition on the specified Device Handle. All configuration of
the device must be completed before calling this VI.

Depending on the current ADAC-LVi transfer mode this call may not return until
completed. See ADAC DIO Config VI for detailed information on asynchronous
operations.

Device Handle (0) Device Handle is a numeric value that identifies the board's DIO
subsystem to be acted upon. Start Device is only available to DIO subsystems configured
for DMA or interrupt operations. The default Device Handle is 0.

error in (no error) Error in describes error conditions occurring before this VI executes.
This cluster defaults to no error.

Device Handle out Device Handle out contains the value of Device Handle in.
