Board ID (0) Specifies the ADAC-LVi board ID number from which the device
subsystem is to be allocated. The board ID number is defined in the ADAC-LVi
configuration file (.CON).

Subsystem Type (0:ADC) Subsystem Type is a numeric value that specifies the board
subsystem to be allocated. The available types are board dependent and are specified in
the [Board] entry section of the specific board's capabilities (.CAP) file.

The available options are:
0:ADC Specifies a specific analog input subsystem on the board to be allocated.
1:DAC Specifies a specific analog output subsystem on the board to be allocated.
2:DIN Specifies a specific digital input subsystem on the board to be allocated.
3:DOT Specifies a specific digital output subsystem on the board to be allocated.
4:COUNTER Specifies a specific COUNTER subsystem on the board to be allocated.

The default Subsystem Type is 0:ADC

Element (0) Element is a numeric value that specifies element number of the Subsystem
Type. Elements range from 0-n for all Subsystem Types.

Most ADC Subsystems have only a single element (0), so the value is typically zero (0).
The other Subsystem Types DAC, DIN, DOT, COUNTER typically have multiple
elements, the first subsystem element is 0, the second is 1, and so forth.

The default Element is 0.

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

Device Handle Device Handle is a numeric value that is used to represent the board in
subsequent VI calls to the allocated subsystem.

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.
