4.4.10. Map Descriptor Example 7 - Analog Input (Area Machine)
A read from the Analog Input Data Array which is shared by a BACNet IP Map Descriptor will return the last scene selected in a
given area on the Lutron eLumen panel. The Lutron Machine Map Descriptor regularly polls the Lutron eLumen panel to retrieve the
scene numbers.

The last scene value may be scaled:

// Analog Input Settings Setup
//
// All values are in decimal ( 0 - 65535 )
// Insert a first available scene number under the Data_Array_High_Scale field for each Object ID or
// use the scale fields as desired to scale scene numbers.
// Object IDs are contiguous

The ARCO function is the same as RDBC except that the length of the Map Descriptor is taken as the number of areas to poll. The
start area number is specified under the “Area” Map Descriptor field. More than one ARCO Map Descriptors may be used to poll two
series of area numbers, eg. from 5-10 and from 300-340. ARCO Map Descriptors with Length 1 fullfil the same function as RDBC
Map Descriptors with the same length.
