ADAC AO Config
The ADAC AO Config VI allocates and configures a device's D/A subsystem returning a
Device Handle to be used in subsequent VI calls.
If the error in cluster contains an error from a previous VI call this VI does nothing and
returns the error in cluster unmodified in the error out. In the event of a previous error the
Device Handle is set to -1.
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 CODE (TWOS_COMP:0) DATA CODE is a numeric value that sets the
hardware data coding configuration of the device.
The available options are:
0:TWOS_COMPLEMENT Two's Complement data coding
1:STRAIGHT_BINARY Straight Binary data coding
2:OFFSET_BINARY Offset Binary data coding
The default DATA CODE is 0:TWOS_COMPLEMENT
