+= StartDIOPulse =
+Start a digital output pulse for the main board or a DIO option card.
+
+{{{
+int StartDIOPulse(int bd, int out, uint8 cond, int count, float pulseWidth, float dutyCycle);
+}}}
+
+{{{
+int StartDIOPulse(int bd, int out, float dutyCycle);
+}}}
+
+== Parameters ==
+
+ * bd - number of digital output card (main board output is not supported for pulse)
+ * output - output number (outputs 1 - 4) only are supported
+ * cond - true = start with output on, false = start with output off
+ * count - count of pulses to output, 0 = continuous until StopDIOPulse
+ * pulseWidth = size of the cycle in seconds
+ * dutyCycle = duty cycle .5 = 50 percent duty cycle
+
+== Return Value ==
+
+ * Returns the result - OK success
+
+== Remarks ==
+
+The main board or option card must already be opened by calling OpenMnBd first. The call does a wait for acknowledgement. If the application is using main board communication events these events may be called during the wait for acknowledgement.
+
+== Examples ==
+
+{{{
+if(StartDIOPulse(1, 1, true, 10, 2.0, 0.5) == OK)
+    DisplayText(0, 0, "10 pulses 1 sec on 1 sec off");
+}}}
+
+{{{
+if(StartDIOPulse(1, 4, 0.7) == OK)
+    DisplayText(0, 0, "Card 1 Output 4 70 pct");
+}}}
