     8== Parameters ==

     10 * dev - number of DAC card.
     11 * reg - DAC register to get - dacAD5422Status, dacAD5422Data, dacAD5422Control, dacLowWeight, dacMaxOutput, dacOutputRange, dacScaleAssign, dacHighWeight, or dacGrossNet
     12 * wait - WAIT_ACK Wait for acknowledgement, NO_WAIT_ACK do not wait for acknowledgement
     13
     14== Return Value ==
     15
     16 * Returns the result - OK success (If WAIT_ACK may be TIMEOUT)

     23
     24{{{
     25   int dac = 1; // number of dac card - not number of slot
     26
     27   // This sets the DAC output for manual control
     28   int result = GetDAC(dac, dacAD5422Control, WAIT_ACK);
     29   DisplayText(0, 0, "GetDAC control result = " + IntToStr(result));
