2231.
The buffer 2231 can be used to create
independent sections within the same DUO
videointercom installation, thus allowing to
have local services without engaging the
main common line.
A few examples are:
- intercom and/or domotic services inside a
single apartment with/without a secondary
entrance;
- intercom and/or domotic services in some
apartments with/without a secondary
entrance;
- connection of a building (with/without
secondary entrance) to one or more main
entrances.
The LED, present in the device, turns on the
switching and for all the time of activation of the
DUO system.

PROGRAMMING

Preliminary notes
- 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 LP.
Use the other numerical intervals to store the
addresses of any additional door stations
connected to the LP 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 buffer, it is necessary
to erase the whole memory of the device
executing the "memory erasing" procedure
and than reprogramming completely the de-
vice.
Programming the numerical intervals
To program the numerical intervals F1÷F10 it
is necessary:
1) enter the programming mode moving the
8mA
jumper J6 from position 1-2 to 2-3; the red
40mA
LED flashes quickly;
2) select the numerical interval to be
0° ÷ +50°C
programmed, positioning the micro
90% RH
switches of SW1 according to the
instructions provided in table 4.3 on page
4.10. For example, to program the interval
F1, set to ON micro switch 1 of SW1
leaving OFF micro switches 2, 3 and 4;
3) store the address of the external door station
or 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
- Make a call, from secondary door
stations.
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.
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
SW1
6) If required, proceed in a similar way to
