= SetDACTrackScale =
Set a DAC output to track scale weight, or not track.

{{{
int SetDACTrackScale(int dev, uint8 scale, DACTrackGrossNet grossnet, int wait);
}}}

== Parameters ==

 * dev - number of DAC card.
 * scale - scale number to track, or 0 for tracking totalizer weight
 * grossnet - track dacTrackGross (track scale gross weight) dacTrackNet (track scale net weight)
 * 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
   int scale = 1;
   DACTrackGrossNet grossnet = dacTrackGross;

   if(SetDACTrackGrossNet(dac, scale, grossnet, WAIT_ACK) != OK)
   {
       DisplayText(0, 0, "SetDACTrackGrossNet Error");
   }
}}}

{{{
// Set DAC 1 and 2 to track scale 1, gross mode, 0 - 10000 wt, max output 10V.
int n;
int scale = 1;
for(n = 1; n <= 2; n++)
{
   SetDACOutputRange(n, dacOutput0to10V, WAIT_ACK);
   SetDACTrackScale(n, scale, dacTrackGross, WAIT_ACK);
   SetDACFloat(n, dacLowWeight, 0.0, WAIT_ACK);
   SetDACFloat(n, dacHighWeight, 10000.0, WAIT_ACK);
   SetDACFloat(n, dacMaxOutput, 10.0, WAIT_ACK);
}
