Programming
In the digital exchanger a yellow LED is present
to show the status of the device: operating mode
(slow blinking) or programming mode (fast
blinking); there are also 4 red LED’s only active
during the programming phase. For correct
operations the digital exchanger must be
programmed in order to univocally recognise
the groups of users connected to it. It is necessary
to program the numerical intervals (max 4)
inside which all the user addresses, belonging
to that specific digital exchanger, are included
(i.e. building or block “A” user addresses from
100 to 120 and from 140 to 150; building or
block “B” user addresses from 0 to 119 and from
121 to 139; building or block “C” user addresses
from 200 to 299; building or block “D” user
addresses from 300 to 450, from 1000 to 2000,
from 4789 to 4790 and the user 5000.
Two are the ways to program the digital
exchanger:
- sending codes using the digital push-button
panel present in the installation (during the
programming phase it is mandatory to switch
OFF a digital door keeper exchanger, if present)
- sending codes using a digital push-button
panel temporarily connected to the device
using terminals ”
+
”, “
-
” and “
DB
”.
Starting programming mode
- Insert the jumper onto termi-
nal board
J1
short circuiting
the two pins. The yellow LED
starts blinking faster.
- On the digital push-button
panel enter the programming
codes followed by the button
"
".
The display of the push-
button panel switches OFF immediately if the
code is recognized by the digital exchanger,
otherwise it remains ON for about 5 second to
indicate that the code has not been recognized
and something wrong happened in the
programming phase.

Exiting programming mode
- Remove the jumper from
terminal board

. The yellow
LED starts blinking slower.
Programming numerical
intervals (code 9990)
To program the numerical intervals it is
necessary:
- enter the code
9990
on the push-button panel
and then press the key
"
"
- enter the starting address of the 1
st
numerical
interval and then press the key
"
"
- the device stores the address, LED1 lights-up
and the display of the push-button panel turns
OFF
- enter the ending address of the 1
st
numerical
interval and then press the key
"
"
- the device stores the address, LED 1 turns
OFF, LED2 lights-up and the display of the
push-button panel turns OFF.
Repeat the operations reported above for all the
numerical intervals you want to program (max
4). Red LED’s show in binary code the numerical
interval you are programming (see table). After
sending the 8
th
and last address on the display
of the push-button panel appears the symbol
“
AAAA
” for about 2 seconds to show that the
device has ended the programming of
numerical intervals and is back in
“
programming mode
”.
Notes
- If an address is not recognized by the digital
exchanger the display of the push button panel
turns OFF with a delay of about 5 seconds.
- If it is not necessary to program all the
numerical intervals it is possible to exit the
programming mode by removing the jumper
from the terminal board
J1
. In such a case only
the complete programmed numerical intervals
are stored.
- If the numerical interval it is composed only of
a single address it must be entered twice as
starting and ending address.
System programming (code 9991)
In this section it is possible to program:
- type of data sent from the exchanged to the
main branch of installation (booking request
and/or self power ON request from user devices,
access control data).
- 4 different operating modes (normal operation
mode-data bus regeneration-operation as al-
arm device-normal operation mode extended
with the sending on the main branch of data
about the busy state of the exchanged branch).
- configuration of terminal
EC
(activation on
call coming from the main branch - activation
on call coming from exchanged branch) and
activation of functions of
red LED’s
.
To program the above mentioned feature it is
necessary:
- enter the code
9991
on the push-button panel
and then press the key
"
"
- enter one of the following codes:
0
booking request managed, self power On
request from internal users not managed,
data for access control system managed
(default value)
1
booking request not managed, self power
On request from internal users not managed,
data for access control system managed
2
booking request managed, self power On
request from internal users managed, data
for access control system managed
3
booking request not managed, self power
On request from internal users managed,
data for access control system managed
4
booking request managed, self power On
request from internal users not managed,
data for access control system not managed
5
booking request not managed, self power
On request from internal users not managed,
data for access control system not managed
6
booking request managed, self power On
request from internal users managed, data
for access control system not managed
7
booking request not managed, self power
On request from internal users managed,
data for access control system not managed
- press the key "
" on the push-button panel,
the digital exchanger stores the code, LED1
lights-up and the display on the digital push
button panel turns OFF immediately
- enter one of the following codes to select the
operating mode:
0
Normal operating mode (default value)
1
Data Bus re-generation.
2
Operation as Alarm Detector Device
4
Normal operation mode extended with the
sending on the main branch of data about
the busy state of the exchanged branch
- press the key
"
"
on the push-button panel,
the digital exchanger stores the code, LED1
turns OFF, LED2 lights-up and the display of
the digital push button panel turns OFF
immediately.
- enter one of the following codes to select the
activation mode of the terminal
EC
and to
activate the
red LED’s
:
0
EC activated only on call received from the
main branch, functions of red LED’s
deactivate (default value)
1
EC activated only on call received from the
exchanged branch, functions of red LED’s
deactivate
2
EC activated only on call received from the
main branch, functions of red LED’s
activated
3
EC activated only on call received from the
exchanged branch, functions of red LED’s
activated
- press the key
"
"
on the push-button panel,
the digital exchanger stores the code, all red
LED’s turn OFF and the display of the digital
push button shows “
AAAA
” to indicate that the
device has ended the system programming
and is back on the “
programming mode
” status.
Operation as Alarm Device
If the digital exchanger is programmed as an
alarm detector device it is sufficient to connect
only the terminals “
+
”, “
-
” and “
DB
” on the data
Bus line. When an alarm code is received by
the device it will activate its internal relays in a
way that terminal “
F1
” is shorted to “
E1
” and
terminal “
F2
” is shorted to “
E2
”. To deactivate
alarms it is necessary to insert and remove
jumper
J1
.
Data bus re-generation
If, in long distance installations, the digital
exchanger is programmed as a Data Bus Re-
generator it is necessary:
- to connect the conductors coming from the
main line to the terminals “
F1
”, “
F2
”, “
-
”, “
DB
”.
- to connect the conductors to the re-generated
data bus line to the terminals “
E1
”, “
E2
”, “
-
”,
“
EB
”.
- to connect the terminal “
+
” (positive power
supply) only to the conductor coming from the
closest power supply.
Downloading and display of numerical
intervals (code 9999)
To download and display on the digital push-
button panel the numerical intervals
programmed in the digital exchanger it is
necessary:
- enter on the digital push button panel the code
9999
and press the key "
". Automatically
the digital exchanger will send the stored codes
to the push-button panel which displays them
in a sequential mode for about 2 seconds
each code; between a numerical interval and
the next one symbol
AAAA
will be displayed
shortly.
If some numerical intervals are not programmed
the display of push-button panel
TD4100
will
remain OFF, whilst the display of the
TD4100MA
shows
000
.
After the 8
th
and last numerical interval the
figures
AAAA
will be shown for about 2 seconds
to indicate that the digital exchanger has ended
the downloading and it is back in “
programming
mode
”
