Cancellazione della memoria
Per cancellare i dati inseriti nella memoria del dispositivo, occorre:
- spostare il ponticello mobile J2dalla posizione 1-2 alla 2-3. Il Led rosso
inizia a lampeggiare velocemente;
- posizionare in ON i microinterruttori 1, 2 e 4 di SW1 (vedere tabella
1);
- attendere circa 4 secondi; il led rosso rimane acceso in modo
continuo;
- entro 4 secondi portare in ON il microinterruttore 3; il led si spegne
per circa 2 secondi, poi, ritorna a lampeggiare velocemente;
- tutti i dati memorizzati nel dispositivo sono stati cancellati;
- riportare in OFF tutti i microinterruttori;
- spostare il ponticello J2 dalla posizione 2-3 alla 1-2; il led ritorna a
lampeggiare lentamente.
Selezione impedenza di chiusura
Nel distributore di linea DV2422A è presente un ponticello J1 che,
posizionato correttamente, permette di riadattare il segnale provenien-
te dalla montante e quindi consentire un corretto funzionamento degli
apparati ad esso collegati.

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 on the same numerical
interval F1 are stored the addresses 100 and 120, on the line L1 are
delivered the video signal of the call addressed to all the
videointercoms whose address is between 100 and 120.
- Audio Intercoms connected to the line L1 and L2 do not require any
programming of the line distributor DV2422A.
- Attention: if during the programming some errorare made or if later
it is necessary to modify some addresses already stored in the
memory of the line distributor DV2422A, it is necessary to erase
the whole memory of the device executing the "memory erasing"
procedure and than reprogramming 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
all microswitches SW1.

Programming the numerical intervals
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
1)
- on the videointercom myLogic
connected to the L1 line
whose address should be
stored in the numerical
interval F1, or on the
videointercom myLogic
whose address should be
stored as the first address in
the numerical interval F1
press the button
(on the videointercoms series Echos,
ExhitoandCompact, press the button
ON without any image on the display and the LED of the line
distributor turns OFF for about 1 sec. 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 myLogic connected to the L1 line whose
address should be stored as the last address in the numerical
interval F1, press the button
Echos,ExhitoandCompact, press the button
turns ON without any image on the display and the LED of the
line distributor turns OFF for about 1 sec. and than starts flashing
again quickly. Line distributor have stored correctly the address
of the last videointercom belonging to the group
4) set OFF the microswitch 1 of SW1. This operation ends the
programming phase of the numerical interval F1 of line L1
5) if required proceed in a similar way to program numerical intervals
F2, F3, F4 and F5 of line L1 repeating the instructions reported on
points 2) and 3) and paying attention to set properly the
microswitches of SW1 according to the numerical interval to be
programmed (see table 1)
6) if required proceed in a similar way to program numerical intervals
F1, F2, F3, F4 and F5 of line L2 repeating the instructions reported
on points 2) and 3) and paying attention to set properly the
); videointercom turns
(on the videointercoms series
