6.3 Sending pre-configured dim-levels
MATRIX ZBA can send configurable commands to the devices in the Switch Multilevel association groups, both
when a pushbutton is single-activated and when the pushbutton is double-activated. These two features each
have two separate configuration possibilities, one for the ON command and one for the OFF command (which one
is sent is decided by the internal switch status).
Example:
It is desired always to set a dimmer at 50% level when it is switched ON, and at 10% level when it switched OFF.
The related configuration parameter (see section about configuration parameters) is then set to:
Byte 1: Enable / Disable
This byte must be set to 1 in order to enable the feature.
Byte 2: Upper switch value
This byte must be set to the value 50 for sending this level when an ON command is transmitted to the dimmer.
Byte 3: Lower switch value
This byte must be set to the value 10 for sending this level when an OFF command is transmitted to the dimmer.
Byte 4: Duration value
This value specifies the time the dimmer shall use to do the level change, 0 means use the dimmer default value,
or 5 means do the change over 5 seconds. For this example, we just specify that the dimmer shall use its default
duration time, so the byte value is set to 0.
So, byte 1 = 1, byte 2 = 50, byte 3 = 10, byte = 0. In hexadecimal it is 01 32 0A 00, and in decimal the value that
the configuration parameter must be set to is: 20056576.
