Data from the last DAQmx buffer read enter through the data terminal. Trigger Packet data is separated into arrays and the counts per channel are tallied in Data Counter.vi. The arrays are passed to Veto Rate Counter Num Display.vi, where count rates are calculated and formatted for display. The time-at-rate-limit logic has been added outside these two vi's, along with it's code to change background colors of the front panel indicators. Again, control references are used to communicate these changes.
