Sequence of data transmission
After a power-on reset all five functions have to be adjusted with five data transmissions. It is recommended that data
information for switch functions are transmitted last because all functions have to be adjusted when the muting is
switched off. The sequence of transmission of other data information is not critical.
The order of data transmission is shown in Figures 4 and 6. The number of data transmissions is unrestricted but before
each data byte the module address MAD and the correct subaddress SAD is required.
