Preliminary notes
- If input lines LI2, LI3, LI4 and output lines
Lo2, Lo3, Lo4 are connected to the system,
they must be programmed to allow the
management of the related addresses.
- Lines LI1 and Lo1 must not be programmed;
line distributor will send automatically on
LI1 and LO1 all the addresses of the system
which are not programmed in any address
intervals of the other lines.
- For the management of the addresses of the
devices connected to the lines LI2, LI3, LI4,
Lo2, Lo3 and Lo4, are available 4 address
intervals (RG1÷RG4) for each line. In each
address interval of an input or output line,
can be stored the address of a single device
or the first and last address of a group of
devices (see example 1b). The addresses
to be stored in the address intervals of the
lines LI2, LI3, LI4 start from 231 up to 253
and must be equal to those stored in the
devices (normally external door stations)
connected to those lines. The addresses to
be stored in the address intervals of the lines
Lo2, Lo3, Lo4 start from 001 up to 200 and
must be equal to those stored in the devices
(normally videointercoms) connected to
those lines.
Examples.
1a -If in the address interval RG1 of the line
LO2 is stored the address 100, on LO2
will be diverted the video signal for calls
addressed only to the videointercom 100.
1 b -If in the same RG1, on the contrary, are
stored addresses 100 (the lowest address)
and 120 (the highest address), on the LO2
line will be diverted the video signal for
calls addressed to any videointercom
whose address is between 100 and 120.
2 - If in the address interval RG1 of the line
LI2 is stored the address 232, the exter-
nal door station connected to the line LI2
must be programmed with the address
232 and would be able to send calls to
any videointercom.
Entering the programming mode
- Remove the cover of the device to access to
the programming buttons.
- Keep pressed the SKIP button as long as the
Led LI2 will light-up and the Led RG1 starts
flashing.
Exit the programming mode
It is possible to exit the programming mode
by one of the following two procedures:
- keep pressed the SKIP button as long as
all the led's RG1, RG2, RG3 and RG4 start
flashing in a sequential way;
- disconnect and connect again the power
supply of the device.
Warning. You will exit automatically the
programming mode if for about 5 minutes no
operations are made; all the data entered until
that moment will be automatically stored.
Programming with the dUo System app
The device can be fully programmed via
Bluetooth by downloading the "dUo System"
app (available for iOS and Android) into your
- 6 -
Mi 2455/1
smartphone or tablet. It is necessary to:
connect a Bluetooth programmer item
PGR2991BT or XE2921 to the system;
after having carried out all the operations
described in paragraph Entering the pro-
gramming mode, set all the dipswitches
of SW1 and SW2 to ON:
ON
ON
1 2 3 4
1 2 3 4
do the programming, turn all the dip-swi-
tches of SW1, SW2 to OFF position and
exit the programming as indicated in the
paragraph Exit the programming mode.
If a Bluetooth programmer cannot be
used, an "emergency" programming
procedure is available, described in
the following paragraphs.
manual programming the address intervals
To program the address intervals of the lines
LI2÷LI4 and Lo2÷Lo4, it is necessary:
1) keep pressed the SKIP button as long as
the Led LI2 will light-up and the Led RG1
starts flashing;
2) enter the address of the first device (the
lowest address) you wish to assign to the
address interval RG1 of the line LI2:
- using dip-switches SW1 and SW2 set
the address to be stored in the address
interval RG1 (see table 1);
- press the oK button; correct storing of
data is confirmed by the simultaneous
lighting-up of all the 4 RG led's;
If in this address interval only one address
should be stored proceed directly to point
"4".
3) enter the address of the last device (the
highest address) you wish to assign to the
address interval RG1 of line LI2, as shown
in the previous point;
4) press the SKIP button to move to the pro-
gramming of address interval RG2 of the
LI2 line; Led LI2 remains ON, Led RG1 turns
OFF and Led RG2 starts flashing;
- to program the address interval RG2
proceed as indicated at the points "2" and
"3";
if it is not necessary to program the ad-
dress intervals RG2, RG3 and RG4, press
several times the SKIP button until the Led
LI3 lights-up and Led RG1 starts flashing;
5) proceed as indicated at the points "2", "3"
and "4" to program the address intervals
RG1, RG2, RG3 and RG4 of the lines LI3 and
LI4;
if it is not necessary to program the ad-
dress intervals of those lines, press sever-
al times the SKIP button until the Led Lo2
lights-up and Led RG1 starts flashing;
6) proceed as indicated at the points "2", "3",
"4", and "5" to program the address inter-
vals of output lines Lo2, Lo3 and Lo4;
7) exit the programming mode as reported in
the chapter "exit the programming mode"
and set all the dip-switches of SW1 and
SW2 in off position;
8) verify the correct operation of the system.
Clearing the memory of the device
To erase completely the memory of the device,
it is necessary:
- enter the programming mode by pressing
the SKIP button; Led LI2 lights-up and Led
RG1 starts flashing;
- set the dip-switches of SW1 and SW2 to the
value 85 moving the switch 1 and 3 of both
SW1 and SW2 to oN position (see table 1);
- keep pressed the oK button until all the
6 Led's LI2, LI3, LI4, Lo2, Lo3 and Lo4
momentarily light-up; the device memory
has been completely cleared;
- keep pressed the SKIP button to exit the
programming mode.
Attention: whether in the line distributor
DM2444 it is made an error during
the programming phase or later it is
requested to modify the already stored
addresses, it is necessary to erase
the whole memory of the device by
executing the procedure "Clearing the
memory of the device" and then program
again completely the device to avoid
undesired programming.
