X1 lower sensor value (input)
Options: 1...255
Y1 Adjusted brightness value (output)
Options: 1...255
The limit and default values of the options are dependent on the number of
value pairs.
In accordance with the number of value pairs, an X-value and the Y-value
can be determined here. The X-value (input value) indicates the value
defined by the KNX. The Y-value indicates the "true" brightness value
used to control the lamps or the 1-10 V control device.
The first X-value is always defined with 1 and the last X-value with 255.

transformation, see Functional
a setting signal may result for the lamps which is therefore less than
or greater than the maximum or minimum brightness values in ETS.
When feeding back the brightness value the transformation is also applied,
so that values available on the KNX are directly comparable.

Note
The characteristic adjustment acts directly on the 1-10 V output and not on
the objects Master: Slave brightness value or Status brightness value.
This means that a characteristic adjustment must be set in the output of
the Light Controller or in the external slave.
In a master/slave combination of LR/S x.16.1 and DG/S 1.1 or DG/S 8.1,
a characteristic adjustment may not be transferred to the DG/S.
