= SetDACReg =
Set a DAC output register.

{{{
int SetDACReg(int dev, DACReg reg, uint16 val, int wait);
}}}

== Parameters ==

 * dev - number of DAC card.
 * reg - DAC register to set - dacAD5422Status, dacAD5422Data, dacAD5422Control, dacLowWeight, dacMaxOutput, dacOutputRange, dacScaleAssign, dacHighWeight, or dacGrossNet
 * val - value to assign to the register
 * 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 ==

{{{
   int dac = 1; // number of dac card - not number of slot
   DACOutputRange outRange = dacOutput0to10V;

   // This sets the DAC output for manual control
   if(SetDACReg(dac, dacAD5422Control, 0x3FF0 | (uint16)outRange, WAIT_ACK) != OK)
   {
       DisplayText(0, 0, "SetDACReg Error");
   }

   uint16 level = 0x7FFF; // Output at half
   if(SetDACReg(dac, dacAD5422Data, level, WAIT_ACK) != OK)
   {
       DisplayText(0, 0, "SetDACReg Set level error");
   }
   
}}}
