2. Second step: activating the halo for the button in question
There are now 2 ways of achieving this.
a. Activation through Process data Prop A config message
This is described in 9.5.1. The corresponding message identifier is 0x10. And the
Data byte containing the information for the symbol LEDs is Byte 3. This can be
found in the K-Matrix as well. The value written in the corresponding byte is bit-coded
similarly to the symbol activation described in 9.9.2.1.

b. Activation through writing in the corresponding object over a write request
There is an object described in the K-Matrix that stores the information for the
activated/deactivated halo LEDs. The object in question is number 104 (0x68).
Writing the corresponding bit-value into this object will lead to the same result as
described in a. the subindex 0 to 5 correspond with the buttons 1 – 6. The value
written in the corresponding byte is bit-coded similarly to the symbol activation
described in chapter 9.9.2.1.
Writing an object is described in chapter 9.4.3.

9.9.3.2 Choosing the active brightness setting for the halo LEDs
There are 3 predefined brightness settings available to choose from in the keypad. The K-
Matrix defines the object and which value stands for which setting. Subindex 0 to 5 stand for
the buttons 1 to 6.
Value

Setting description
0x00
Setting 0 (even)
Brightness for LEDs button wise
0x01
Setting 1 (even)
Brightness for LEDs button wise
0x02
Setting 2
(individual)
Brightness for LEDs individually
