ADAC LabVIEW VI 53
ADAC AO Update Channel
The ADAC AO Update Channel VI performs an immediate, untimed output on the
specified DAC Element in the specified data units.
Board ID (0) Specifies the ADAC-LVi board ID number to be used in this acquisition.
The ID numbers are defined in the configuration file ADAC-LVi.con located in the
Windows main directory.
Data (0.00) Data is a double value that specifies the DAC channel output value.
UNITS (VOLTS:0) UNITS is a numeric value that sets the units in which the DATA
output parameter is specified.
The available options are:
0:VOLTS The voltage to output
1:RAWDATA The hardware register bits output
2:CURRENT The current to output
The default UNITS 0:VOLTS
Iteration (init:0) Iteration controls when the ADAC-LVi device subsystem allocation
and device initialization is performed. If iteration is 0, the VI allocates the device and
initializes it with the hardware specifications connected to the VI. The VI then starts the
acquisition and reads the data. If iteration is greater than zero, then VI assumes that the
current configuration is valid and starts the acquisition, then reads the data.
