DVA-102ETH AND ANALOG ZONES ACTIVATED BY CONTACT,
WITH LOUDSPEAKER LINE SURVEILLANCE
DESCRIPTION
The PC, the DVA-102ETH and the
DC-600ETH desk are connected
to the Ethernet network.
DVA-102ETH and DALA-01/0B
are interconnected by means of
an RS485 bus.
Three output contacts of the
DVA-102ETH (contacts 1, 2 and
3) are configured to activate the
priority of the analog power
units.
The system supports:
Sending
pre-recorded
messages from the DVA-102ETH
to the power units by activating
the input contacts of the DVA-
102ETH (in the diagram, CTI-1
and CTI-2).
Sending
pre-recorded
messages from the DVA-102ETH
to the power units, activating
these from the PC.
Sending audio from the DC-
600ETH desk to the power units
(digital audio from the desk to
the DVA-102ETH, and analog
audio from the DVA-102ETH to
the power units).
Zone selection from the DC-
600ETH desk or from the PC,
using the output contacts of the
DVA-102ETH (in the diagram,
Ct1, Ct2 and Ct3).
Through the configuration of
the input contacts of the DVA-
102ETH (in the diagram, contacts
3, 4 and 5), an analog
microphone with zone selection
(MD-94R6) can be used. When a
zone is selected from the MD-
94R6 desk, the DVA-102ETH
activates the output contact
corresponding
to
the
zone
selected.
Surveillance of the status of the loudspeaker lines by the DALA-01/0B. The status of the lines is sent through the
RS485 connection to the DVA-102ETH, and this sends the data via Ethernet to the PC and DC-600ETH. RS485
communication between DALA-01/0B and DVA-102ETH supports CSMA or POLLING protocol.
Reception of system incidents and alarms by the PC, the DVA-102ETH and the DC-600ETH desk.
