DV2422A.
In DUO digital systems the line
distributor DV2422A delivers the video signal,
after a call, only to those videointercoms
connected to the line L1 and L2 whose address
has been previously programmed as belonging
to them; audio and call signals, on the contrary,
are delivered to all the devices connected to
the lines L1 and L2 without considering their
address. The LED, present in the device, turns
on the switching and for all the time of activation
of the DUO system. The jumper J1 is used to
adapt the line impedance to the needs of the
installation.

PROGRAMMING

Preliminary notes
- If in the installation it is present the line buffer
art.2230 it is mandatory to program it before
programming the line distributor DV2422A.
- To manage videointercom addresses
connected to the lines L1 and L2 are available
5 numerical intervals (F1÷F5) for each line
(L1-L2). In each numerical interval can be
stored the address of a single device or the
first and the last address of a group of
videointercoms, with sequential addresses,
related to the same line. For example if in the
numerical interval F1 of the line L1 is stored
the address 100, on the line L1 only the video
signal of the calls addressed to the
videointercom 100 is delivered. Vice-versa if
25
on the same numerical interval F1 are stored
the addresses 100 and 120, on the line L1
1 "
are delivered the video signal of the call
addressed to all the videointercoms whose
address is between 100 and 120.

L2 do not require any programming of the line
distributor DV2422A.
- Attention: if during the programming some
error are made or if later it is necessary to
modify some addresses already stored
in the memory of
DV2422A, it is necessary to erase the whole
memory of the device executing the
"memory erasing" procedure and than repro-
gramming completely the device.
Entering the programming mode
- Move the jumper J2 from the position 1-2 to
2-3; the red LED flashes quickly.
Exiting the programming mode
- Move the jumper J2 from the position 2-3 to
1-2; the red LED come back to flashing slowly
(every 2 seconds). You should set OFF also
8mA
all microswitches SW1.

To program the numerical intervals F1÷F5 it is
necessary:
1) enter the programming mode moving the
jumper J2 from position 1-2 to 2-3; the red
LED flashes quickly
2) program the address of the videointercom
to assign to the first numerical interval F1
of L1 line or the address of the first
videointercom belonging to the group of
devices which belongs to the numerical
interval F1. To make this operation it is
necessary:
- set ON the microswitch 1 of SW1 leaving
OFF micro-switches 2, 3 and 4 (see table
4.1)
(MT13 - En 2015)

- on the videointercom connected to the L1
line whose address should be stored in
the numerical interval F1, or on the
videointercom whose address should be
stored as the first address in the numerical
interval F1 press the button
videointercoms series myLogic and
Zhero) or the button
intercoms series Echos and Exhito);
videointercom turns ON without any image
on the display and the LED of the line
distributor turns OFF for about a second
and than starts flashing again quickly. Line
distributor have stored correctly the
address of the first videointercom.
3) If to the numerical interval F1 belongs only
the videointercom programmed above,
move to the point 4), if not, it is necessary to
program the address of the last
videointercom belonging to the group. To
execute this operation it is necessary:
- on the videointercom connected to the L1
line whose address should be stored as
the last address in the numerical interval
F1, press the button
intercoms series myLogic and Zhero)
or the button
series Echos and Exhito); videointercom
turns ON without any image on the display
and the LED of the line distributor turns
OFF for about a second and than starts
flashing again quickly. Line distributor have
stored correctly the address of the last
videointercom belonging to the group;
