4.4.8.Map Descriptor Example 5 - Analog Output 1 (Zone Machine)
A write to the Analog Output Data Array which is shared by a BACNet IP Map Descriptor will command a zone on the Lutron eLumen panel to the written intensity. Intensities are written as a percentage value (0 to 100%).

The zone field must be used to indicate the start zone number that will be associated with the first element of the Data Array specified under Data_Array_Name . Zone numbers increase with the Length field in association with increasing offset into the Data Array.
Fade and Delay times per zone must be preloaded into the Data Array specified under “DA_Lut_Parms”: //================================================================================
//Analog Output1 Settings Setup
//All values are in decimal ( 0 - 65535 )
//Fade time in even locations, Delay time in uneven locations
//Fill in time values under Preload_Data_Value
