4.2.3 Operating Extended AS-i Slaves with Standard AS-i Masters

Note

Please note the following information about operating extended AS-i slaves with

standard AS-i masters!

S If A slaves are connected to standard masters, make sure that the most

significant slave bit (bit 4) of each A slave is set to “0”. The most significant

parameter bit (bit 4) must also be set to “1” (default value).

Without these settings, the A slave cannot be operated with a standard master.
