DAB1 DISTRIBUTED AUDIO SYSTEM
Paging Connections
(see Figure 13)
The DAB1’s Paging connections allow connection of an audio input from a telephone system,
microphone preamp or other device to be distributed to designated Paging zones when triggered
by the C
ONTROL
Input. (Paging must be configured in the Sonance Control Manager.)
When 5 – 24VDC is present at the DAB1 C
ONTROL
I
N
terminals, all system zones set to ‘Allow
Paging’ as configured with the Sonance Control Manager will switch to audio from the P
AGE
I
N
jack. When the control voltage drops to 0VDC, audio in the zones will switch back to the select-
ed source component.

RS-232 Connection
(see Figure 14)
The DAB1’s RS-232 connection allows it to send or receive serial commands to or from other
components. The RS-232 connection uses a female DB-9 connector with the following pinout
configuration:

Since different serial devices have different RS-232 connection configurations, consult the
documentation of the device you want to connect to the DAB1 to determine what cable/adapter
may be required.
RS-422 Port
(see Figure 3, on page 10)
The RS-422 port allows the DAB1’s capabilities to be expanded in the future. At the time of this writing (05/07) the
RS-422 port was not active. Check www.sonance.com periodically for the latest information about this feature.
