The push-button of VD2121CAGL external door
station is programmed with the same calling
code as the internal station (100) and therefore
needs no programming. The encoder module
must be programmed as illustrated below only if
you want to change some functions or add
additional devices to the videokit.

Factory setting

- External Door Station Address = 231
- Address associated with First Button = 100
- Address associated with First Button of first

additional push-button panel = 102

- Lock actuation time = 3 seconds
- Buttons with special functions = none

Entering the programming mode

Remove the plate.
Move the jumper J1 from position 1-2 to 2-3;
you hear the programming tone and the red
LEDs turn ON (R).

Entering codes or addresses
- Codes and/or addresses must have three digits

(hundreds, tens, units); codes and/or addresses
with tens and units or units only must be
completed by adding zeros. For example,
address 96 becomes 096 and address 5
becomes 005.

- Enter one digit at a time by pressing the “P1”

button for a number of times “n”, where “n” is the
value of the digit you want to enter, followed by
a pause of about 2 seconds before you go to
the next digit (a tone on the loudspeaker will tell
you when to go to the next digit). The maximum
value you can enter is 255. For example, to
enter code 096 you must:
- press the “P1” button 10 times to enter digit
0 and wait for 2 seconds until you hear a tone in
the loudspeaker.
- press the “P1” button 9 times to enter digit 9
and wait for 2 seconds until you hear a tone on
the loudspeaker.
- press the “P1” button 6 times to enter digit 6
and wait for 2 seconds until you hear a tone on
the loudspeaker.

Note: - remember to confirm the codes you have

entered as explained in the programming
chapters.

Programming procedure
To make the programming it necessary to:

a) enter the programming mode following the

instructions described in “

Entering the

programming mode”;

b) enter the three digits of the programming

code you want to change following the
instructions contained in “

Entering codes or

address”; press PN to confirm: you hear the
confirmation tone and the red LEDs start
flashing.

c) make the operations described in the

specific programming chapter.

d) continue with another programming operation

or exit moving the jumper J1 from 2-3 to 1-2.

Entering the External Door Station address
(

code 111)

In this mode you can code the external door
station address with codes from 231 to 250.

Enter the programming mode following the
instructions described in “

Entering the pro-

gramming mode”;
Enter code 111 and press Pn; you hear a
confirmation tone and the red LEDs start flash-
ing.

Exit the programming mode

To exit the programming mode, you must bring
the jumper J1 from position 2-3 back to position
1-2.

Using the push-buttons for programming

Press button "Pn" and "P1" to enter addresses
or codes.
Pn:

Press this button to confirm code
programming or go to the next
programming step.

P1:

Press this button to increase the value
you want to enter. Press the button for a
nu

mber of times equal to the digit you want

to enter (digit 1 = 1 time; digit 9 = 9 times;
digit 0 = press “P1” 10 times).

The pressure of the “P1” button is confirmed by
an acoustic tone on the loudspeaker.

Dial the code number you have chosen for the
external door station and press Pn to confirm;
you hear the confirmation tone and the red
LEDs go back ON without flashing.
Continue by entering the code of a new pro-
gramming or exit the programming mode by
moving the jumper J1 to position 1-2.

Entering the First Button address

(code 112)

The VD2121CAGL board has 2 buttons: PN
and P1. PN is the first button and P1 takes the
next value (i.e.: Pn = 001, P1 = 002; Pn = 058, P1
= 059).
The first button (Pn) is coded by default with
address 100; if you want to change it, you must:

enter the programming mode following the
instructions described in “

Entering the pro-

gramming mode”;
enter code 112 and press Pn; you hear a
confirmation tone and the red LEDs start flash-
ing;
dial the address you want to assign to Pn.
Extensions must be coded with numbers from
001 to 200;
press Pn; you hear a confirmation tone and the
red LEDs go back ON without flashing;
continue by entering the code of a new pro-
gramming or exit the programming mode by
moving the jumper J1 to position 1-2.

Entering the address of the First Button of
the first additional push-button panel (

code

113).
To increase the number of calls, you must
integrate the VD2121CAGL external station with
one or more additional AG100TS push-button
panels (max. 16). Each additional push-button
panel must be coded with the 4 microswitches
provided on the board (see instructions attached
to the product). Moreover, an address must be
assigned to the first button of the first additional
push-button panel. The next buttons of all the
additional push-button panels will automatically
take progressive numbers. This address must
be higher than the address of the P1 button of the
VD2121CAGL external door station.
The first button (Pn) of the first additional
AG100TS push-button panel is coded by default
with address 102; if you want to change it, you
must:

enter the programming mode following the
instructions described in “

Entering the pro-

gramming mode”;
enter code 113 and press Pn; you hear a
confirmation tone and the red LEDs start flash-
ing;
dial the address you want to assign to the Pn
button of the first additional push-button panel.
Addresses must be numbers from 001 and
200; remember that addresses 100 and 101
are assigned to the 2 VD2121CAGL buttons
by default;
continue by entering the code of a new pro-
gramming or exit the programming mode by
moving the jumper J1 to position 1-2.
