2. Activation through writing in the corresponding object with a write request
There is an object described in the K-Matrix that stores the information for the temporal
pattern setting for the symbol LEDs. The object in question is number 107 (0x6B). The
subindexes 0 through 5 correspond with the buttons 1 to 6. Writing an object is described
in 9.4.3.

9.9.2.5 Adjusting the timings in flash modes
The 2 flashing modes described in chapter 9.9.2.4 can be adjusted by the user. This means
that the timings of how long the LED stays on and the period when it is turned on can be
adjusted. For this there are 4 objects defined in the K-Matrix:
Object
Object name
Object description
41 (0x29)
Flash_Slow_On_Time
Timing for how long the LED is on in Flash mode slow
42 (0x2A)
Flash_Slow_Period_ms Time after which the LED is turned on in Flash mode slow
43 (0x2B)
Flash_Fast_On_Time
Timing for how long the LED is on in Flash mode fast
44 (0x2C)
Flash_Fast_Period_ms Time after which the LED is turned on in Flash mode fast
There are default values defined for each object in the K-Matrix. But each value can be
changed by hand. The values can be edited by means of a Prop A config message as
described in 9.5.1.
Example data fields for setting the timing of the fast mode to 20ms LED on after each 50ms:

9.9.2.6 Changing the global brightness for the symbol LEDs
The global brightness setting is a setting that dims the LEDs above all other settings. So to get
realistic values in the aforementioned settings the global brightness needs to be set to 100%.
The brightness is coded in 250 steps from 0 (0%) to 250 (100%). The setting of global
brightness always affects all Symbol LEDs at once.
There are 2 ways to set the global brightness for the symbol LEDs.
