= GetDAC =
Get a DAC register value.

{{{
int GetDAC(int dev, DACReg reg, int wait);
}}}

== Parameters ==

 * dev - number of DAC card.
 * reg - DAC register to get - dacAD5422Status, dacAD5422Data, dacAD5422Control, dacLowWeight, dacMaxOutput, dacOutputRange, dacScaleAssign, dacHighWeight, or dacGrossNet
 * wait - WAIT_ACK Wait for acknowledgement, NO_WAIT_ACK do not wait for acknowledgement

== Return Value ==

 * Returns the result - OK success (If WAIT_ACK may be TIMEOUT)

== Remarks ==

The option card must already be opened by calling OpenMnBd(dev) first. If the application is using main board communication events these events may be called during the wait for acknowledgement.

== Examples ==

{{{
   extern uint16 g_nDACValue16;
   extern float g_fDACValue;

   int dac = 1; // number of dac card - not number of slot

   // Gets the DAC control register value
   if(GetDAC(dac, dacAD5422Control, WAIT_ACK) == OK)
   {
      DisplayText(0, 0, "GetDAC control result = " + IntToStr(g_nDACValue16));
   }
   // Gets the DAC high weight register value
   if(GetDAC(dac, dacHighWeight, WAIT_ACK) == OK)
   {
      DisplayText(0, 0, "GetDAC high weight = " + FloatToStr(g_fDACValue));
   }
}}}
