+= SetOutputMask =
+Set the output states of one or more digital outputs to ON or OFF for the main board or a DIO option card.
+
+{{{
+int SetOutputMask(int bd, uint32 mask, uint32 output);
+}}}
+
+== Parameters ==
+
+ * bd - 0 for main board or number of digital output card
+ * mask - bit mask to specify which outputs will be affected
+ * output - bit mask to specify state of outputs
+
+== 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 ==
+
+{{{
+// Affect outputs 1 - 3 Mask = 1 + 2 + 4 = 7
+if(SetOutputMask(MNBD_DEV, 7, 4) == OK)
+    DisplayText(0, 0, "Out 3 set to ON 1 and 2 set to OFF");
+}}}
+
+{{{
+// Affect outputs 1 - 4 Mask = 1 + 2 + 4 + 8 = 15 decimal = 0x0F hexadecimal
+// Set 1 and 2 on = 1 + 2 = 3
+if(SetOutputMask(MNBD_DEV, 0x0F, 3) == OK)
+    DisplayText(0, 0, "1 and 2 ON  - 3 and 4 OFF");
