Config_ATrig_Event_Message is a high-level function for NI-DAQ event messaging.
Because this function uses the current inputRange and polarity settings to translate
trigLevel and windowSize into binary units, you should not call
AI_Configure and change
these settings after you have called
Config_ATrig_Event_Message. For more information
on NI-DAQ event messaging, see the low-level function
Config_DAQ_Event_Message.
