Analog Output VIs
AOut.VI
Sets the value of a D/A output.
Summary:
Inputs: BoardNum [U32] - The board number assigned when installed with InstaCal. Can
be 0 to 100.
Channel [I32] - Number of D/A channel to update.
Range [I32] - A/D Range code
DataValue [U16] - Value to update D/A.
Outputs: ErrCode [I32] - Error code. See ErrMsg.VI
Arguments:
BoardNum The board number associated with a board when it was installed with InstaCal. The
specified board must have a D/A.
Channel The maximum allowable channel depends on which type of D/A board is being
used.
DataValue Must be in the range 0 – N, where N is the value 2
Resolution
- 1 of the converter.
Range If the selected D/A board does not have a programmable range feature, this
argument will be ignored. Otherwise, the gain can be set to any of the ranges that
are supported by the selected D/A board. See the "
Range input values " table on
page 19 for valid values. Refer to board-specific information contained in the
Universal Library User's Guide (available on our web site at
www.mccdaq.com/PDFmanuals/sm-ul-user-guide.pdf ) for the list of ranges
supported by each board.
For simultaneous-update boards: If you have set the simultaneous update jumper for simultaneous operation,
you should use AOutScBg.VI or AOutScFg.VI for simultaneous update of multiple channels. AOut.VI always
writes the D/A data then reads the D/A, which causes the D/A output to be updated.
