Examples:
Figure 13. Hexadecimal address settings.
The Central Unit always has address 00 and other modules can then be addressed in
ascending sequence. Each address must be unique within the installation regardless of
which bus it is connected to. Transmitters in non-speech systems must have hex 0 as the
first (most significant) digit unless sequential transmission is used.
Note: In speech systems the transmitters must be in the address range for speech
transmitters (hex address 80-FF).
