5.1 Addressing the AC2489 module
In the factory setting, initially only the first slave gives a signal on address 0. It can
be addressed to any address between 1A...31B.
If this slave is addressed, the second slave with the address 0 appears
automatically in the display. Now this slave can be addressed to any address
between 1A...31B.
Both slaves can be assigned any A/B addresses (e.g. 3A/6A or 9A/25B....).
No address can be assigned twice (e.g. 3A/3A or 9B/9B).
If a slave with the ID code "A" (extended address mode possible) is used in
combination with a master of the 1st generation (version 2.0),
- the parameter P3 must be 1 and the output bit D3 must be 0.* The output bit
D3 must not be used.
- an address between 1A and 31A must be assigned to this slave.
