SERVICE MODULES
2230.
The buffer has been designed to sepa-
rate and isolate the devices of an apartment (or
apartments) that have the need for common
services (home automation, intercommunic-
ating, etc..) without engaging the main line.
The LED, present in the device, turns on the
switching and for all the time of activation of the
DUO system.

PROGRAMMING
Preliminary notes
- It is mandatory to program the line buffer
art.2230 before programming the line
distributor DV2422A.
- To manage videointercom or intercom
addresses connected to the lines LS are
available 10 numerical intervals (F1÷F10). In
each numerical interval can be stored the
address of a single device or the first and the
last address of a group of intercoms/
videointercoms, with sequential addresses,
related to the same line. For example if in the
numerical interval F1 is stored the address
100, on the line LS only the calls addressed to
the intercom/videointercom 100 is delivered.
Vice-versa if on the same numerical interval
F1 are stored the addresses 100 and 120, on
the line LS are delivered the call addressed
to all the intercoms/videointercoms whose
address is between 100 and 120.
- To enable the secondary door station , if
present in the riser, you need to store, in one
of the 10 numerical intervals, the address of
the door station connected to terminals LS.
Use the other numerical intervals to store the
addresses of any additional door stations
connected to the LS terminals.
- 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 the line buffer, it is

necessary to erase the whole memory of
the device executing the “memory erasing“
procedure and than reprogramming
completely the device.
Programming the numerical intervals
To program the numerical intervals F1÷F10 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) select the numerical interval to be
programmed, positioning the micro
switches of SW1 according to the
instructions provided in table 4.2. For
example, to program the interval F1, set to
ON micro switch 1 of SW1 leaving OFF
micro switches 2, 3 and 4;
4) From the internal station, having the user
address with the highest value, store the
address following the procedure of the
selected model. The device acquires the
address of the last internal station belonging
to the group, allowing all the extensions
programmed in interval F1 to connect to the
LS line.
5) Set OFF the microswitch 1 of SW1. This
operation ends the programming phase of
the numerical interval F1.
6) If required, proceed in a similar way to
program the other 9 numerical intervals
repeating the instructions reported on points
from 2 to 5 and paying attention to set
properly the microswitches of SW1
according to the numerical interval to be
programmed (see table 4.2).

3) store the address of the internal station by
following the procedure described here
below.
- Videointercom Zhero, myLogic: press
the button
.
- Videointercom Echos, Exhito: press the
button
- Intercom Exhito: pick up the handset,
press the button
, hang up the handset.
In case you wish to program a group of
addresses, store the address with the lowest
value first.
If the final group address also has to be
programmed in the interval, continue with
step 4; if, on the other hand, only one address
needs to be programmed, move on to step
5.
Notes.
- Proper storage is indicated by the buffer
LED turning off for one second and then
turning back on in flashing mode.
- Possible audio noise signals in this phase
don't notice any anomaly in the
programming.
