Type of system.
The video door entry unit can only be used on ELVOX video door entry systems of the DigiBus digital type. It will
therefore be necessary to use solely ELVOX power supplies in the DigiBus range (for the specifications see the
relevant ELVOX manuals).
To accomplish the audio function, the type of connection towards the pillar has “4 wires” (plus the power supply):
- Digital line;
- Digital line power supply;
- Voice unit;
- Ground;
- Power supply (positive);
- Power supply (negative).
To accomplish the video function (integrated with the audio portion) a video camera must be installed on the
outdoor station and the video connection then needs to be wired towards the pillar:
- Video signal.
- Video signal ground.
The DigiBus system enables creating types of systems where device and control identification is digital.
Depending on the system configuration, each of the connected devices has a numerical code with 4 or 8 digits
(which must be univocal) and is able to receive and send the data packets that contain all the information relating
to communication management. Each data packet is composed of identification of the destination device and the
command that this device must carry out.
All the typical control operations of a video door entry system such as, for instance, call, electric lock opening,
switching on stair lights, etc., are therefore all coded.
Whereas, the voice unit for voice communication and the video signal to see the images are signals that remain
analogue.
As regards the type of cables to use for the connection between the system components, both towards the pillar
and towards the outdoor station, you are advised to refer to the following table and the diagrams illustrated in the
"INSTALLATION DIAGRAMS AND EXAMPLES" chapter:

Description of terminals.
The video door entry unit has a 16-pin connector for connecting the audio and video signals, power supplies, calls
and all the optional functions (fig. 2).
Advantages of the DigiBus system.
The most important advantage offered by the DigiBus system compared to a classic analogue video door entry
system (8 wires + n) is the “saving” (on the pillar side) of the single call wire for each indoor station (necessary, on
the contrary, in the classic analogue system).
Thanks to this feature, the system is ideal to be used in installations where there are many indoor stations (for ex-
ample, large building complexes) since it considerably simplifies wiring operations, because the number of cables
is always the same irrespective of the number of indoor stations to install:
- audio door entry system: 4 wires (plus 2 for the power supply).
- video door entry system: 8 wires (including the power supply).
Another advantage of using the DigiBus system is the extreme flexibility for future expansion of the system; it is
indeed possible to add new indoor stations by simply using the pillar without having to connect additional cables
to the power supply.
Digital management of all the commands (call bell duration, bell type, call time duration, answer time duration,
access via password or programmed key, etc.) lastly enables programming all the parameters of the devices ac-
cording to the different needs of each user.

The video door entry unit must be installed with the procedure illustrated in figure 3; if the device has to be removed
from the wall (maintenance, etc.), unhook the front panel from the metal bracket (see figures 4, 5 and 6).
It is recommended to hook the video door entry unit to the bracket before powering up the system, making
sure that the mechanical coupling is perfect.

Power input.
The consumption of the video door entry unit depends on the current operating mode of the device (standby, on
call, red/green LED on, control activation, etc.).
The average values of the power input in the three typical operating modes are the following:
- on standby 15 mA.
- on call 200 mA.
- with monitor on 150 mA.
N.B. The above values are given as a guideline.
Operation of the ELVOX DigiBus system.
The ELVOX DigiBus system permits digital coding of the devices and commands that are sent or that come from
the external plate; the latter can be considered as the master device (main appliance governing communication
between the digital devices in the system), while every other single digital device can be considered as a slave
(secondary appliance that is piloted/controlled by the master).
The external plate is therefore absolutely essential for operation of the DigiBus system and must always
be installed in the system. All the programming parameters (call time, type of bell, electric lock opening, code
numbers of the indoor stations, etc.) are set and stored (until the next programming) in the main external plate
(EEPROM memory).
NOTE: Alternatively to the outdoor plate there are other master devices such as, for example, the consumer unit in
the porter's lodge, the consumer unit on EN 50022 rails for PC, etc. (see the ELVOX DigiBus catalogue).
For programming the plate and all the parameters correlated with it, see the relevant ELVOX technical literature.
The communication protocol used by the DigiBus system is proprietary ELVOX and is “serial-similar” with active
level at 12 V d.c. (0 V d.c. at rest) and communication input on the digital line of 25 mA (current limiter on plate).
The standard speed is 600 b/s that enables reaching distances on the digital bus of a few kilometres.
Compatible ELVOX power supplies.
The power supplies that can be used for installing the system are all those in the ELVOX DigiBus range; in particular
the following articles are recommended:
•6948 (standard video door entry unit power supply).
•6947 (supplementary power supply for monitor and call signal).
•6942 (supplementary power supply for plates, consumer unit and video distributors).
For all the technical characteristics (power supply voltage, current delivered, absorption, description of terminals,
etc.) see the ELVOX technical manuals.

General information on the digital commands
The digital commands are data packets that can be sent by every digital device containing the information/in-
structions that enable activating a particular function (unlocking, switching on stair lights, activating auxiliary func-
tion, etc.) by means of an actuator.
Typically, in the DigiBus system, the main commands are the following:
- LOCK command that controls the actuator S1
- CALL-F1 command that controls the actuator R1
- CALL-F2 command that controls the actuator R2
The actuators can be relays or voltage generators in the power supplies that are controlled by master devices
(plates or consumer units) after receiving the data packet containing the command to actuate.
In the case of the main commands listed above (and with reference to the DigiBus power supply 6948) the actua-
tors are the following:
- actuator S1 Relay →the contact S1 closes to 0 (ground) on receiving the command.
It is used to open the electrical lock via the power supply on terminals no. 15 and 0.
- actuator R1 Voltage generator 12 V d.c. (max 150 mA) →active on receiving the command.
It is used to control an auxiliary external relay (e.g. switching on stair lights).
- actuator R2 Voltage generator 12 V d.c. (max 150 mA) →active on receiving the command.
It is used to control an auxiliary external relay (e.g. supplementary acoustic repeater).
Each single command is sent by pressing a button (associated with the command) on the device. Other com-
mands can be associated with other buttons that may be present.
List of standard commands:
CALL-PLATE+TLC Call from plate with video camera activation.
CALL-PLATE Call from plate without video camera.
CALL-AUDIO DOOR ENTRY UNIT Call from audio door entry unit.
LOCK Unlocking.
CALL-F1..F8 Call functions F1..F8.
CALL-CONSUMER UNIT Call from consumer unit.
Additional technical and installation details are given in the “FUNCTIONS OF THE VIDEO DOOR ENTRY UNIT”
chapter and the attached diagrams “INSTALLATION DIAGRAMS AND EXAMPLES”.

The main function of the device is, by communicating over the audio and video channels, to identify anyone want-
ing to enter the dwelling by using the outdoor station and to open the electrical lock of the gate or door when
appropriate.
In addition, the video door entry unit enables additional functions that are:
- turning on stair lights;
- self-start outdoor station;
- additional auxiliary function.
All the functions of the video door entry unit are enabled by pressing the dedicated buttons.
The main operating states of the video door entry unit are the following:
- With MONITOR ON (the LCD monitor and the backlighting LEDs of the buttons are on).
- With MONITOR OFF (the LCD monitor and the backlighting LEDs of the buttons are off).

Video signal cable selector.
The selector on the back of the video door entry unit by the letters "DC", depending on the type of video signal
used, permits selecting the most appropriate mode to reduce interference on this signal.
The selector, shown in the figure with V1, permits two different settings depending on whether the video signal
from the outdoor station is wired with coaxial cable (polarized video signal) or, alternatively, with a twisted pair
(differential video signal).
V1 in position “D” = twisted pair (connect the terminals V1 and V3)
V1 in position “C” (default position) = coaxial cable 75 Ω (connect the terminals V1 and M)

The “Second Function” button (2ndF) and type of unit outside the door.
Sending the main commands CALL-F1, CALL-F2 and LOCK is controlled by pressing the related buttons of the
video door entry unit A, C and B.
The system moreover enables sending additional commands of “auxiliary functions” that can be used, for exam-
ple, to govern cyclical viewing of a number of indoor video cameras, unlocking from the landing or other auxiliary
devices, switching on stair lights, etc.; to be able to use these commands it is necessary to configure button C of
the video door entry unit as the “second function” button (2ndf).
To do this you need to put selector S1, which is on the back of the video door entry unit by the numbers "1 2"
(see following figure), onto position 2.
To set the type of unit outside the door (as preferred between “AUDIO” outside the door or “DOORBELL” outside
the door) it is necessary to set selector S2 as indicated below.

Figure 10 - Button release
Numerical coding of the video door entry unit.
The Digibus video door entry unit is identified in the system
with a numerical code with 4 or 8 digits (parameter to set on
the DigiBus plate); it is then necessary to do the programming
for this code by carrying out the following procedure:
• Unhook the button cover of button C
(control function CALL-F2);

13
• Using a screwdriver or small tool, briefly press the push-button Runder button D (figure 11);
• Press and hold down button B for at least 5 seconds (door-opening function) (figure 12);
• The red LED of the video door entry unit lights up confirming that the device is ready to be coded.
• Send a call to the video door entry unit with the desired numerical code; if you have a plate with an alphanumeri-
cal keypad it is sufficient to key in the code and send it to the device by pressing button “C” on the plate.
• Programming the video door entry unit with the desired code is confirmed by the red LED going out on the
monitor and by an audible confirmation signal on the plate.
• Lastly, check that the video door entry unit answers the call (with the alphanumerical plate key in the set code
and press button “C” on the plate).
If you do not have a plate with an alphanumerical keypad or with single buttons you need to use the specific
ELVOX programmer or a PC with a serial interface and ELVOX software (see the “PROGRAMMING THE DigiBus
PLATE”).

Call answering.
When a call is made from an outdoor station (external plate or consumer unit), the video door entry unit related to
the called numerical identification modulates the programmed call tone on the speaker; the video door entry unit
then emits an audible warning and, if the video signal has been connected as well, the LCD monitor lights up to
display the person calling.
Since it is a speakerphone system, to answer the call and communicate with the outdoor station it is necessary to
press the answer button D (fig. 6) and keep it pressed throughout the entire conversation.
The time for inserting the call is set as the plate parameter; these parameters can all be set at the time of program-
ming the outdoor plate (master) and concern various functions such as timing, recording users, etc. (For a full list
of parameters see the ELVOX technical literature for the plate used and refer to the “MAIN CONFIGURATIONS”
chapter as well).
Self-start function.
This function is used to activate the audio and video communication on the outdoor station without a call being
received; this function may be useful, for example, to check the area outside
The self-start function activates only if button C is configured as 2ndF (see “The second function button (2ndF) and
type of outside the door” section); having done this, to activate the self-start on the outdoor plate it is necessary
to send one of the following commands:
•CALL-F3
•CALL-F4
•CALL-F5
Pressing button E a number of times in succession (always keeping button C pressed) sends the commands
CALL-F3, CALL-F4 and CALL-F5 cyclically as well.
If the self-start function is enabled on the plate and the related numerical parameter is set, on receiving the sent
command the plate self-starts on the calling video door entry unit (for the plate programming details relating to this
function see the “MAIN CONFIGURATIONS” – Programming DigiBus plate (basic notions) section).
Confidential Conversation.
The “Confidential Conversation” function is used to communicate with the outdoor station only if a call has
arrived or there has been a self-start. It is not possible to listen to other communications in progress or self-start
while a conversation is in progress.
In DigiBus systems the “Confidential Conversation” function is always enabled.
NOTE: The voice unit towards outside the door is always on.
Functions of the video door entry unit

15
The additional power supply is typically necessary for systems in building complexes where numerous video door
entry units co-exist.
For single dwellings or small apartment blocks, where up to 10 video door entry units can be installed of which
at most 2 in parallel, it is possible to use the auxiliary power supply output of the main power supply e.g. 6948
terminals 15 – 0 output 15 V d.c.); if there are more video door entry units it is necessary to use the additional
power supplies (ELVOX 6582 15 VA 13.5 V d.c., one for every 30 additional video door entry units).
“Door open” signal.
This function is used to display a “Door Open” signal on the video door entry unit by lighting up a green LED on
the right-hand side of the LCD monitor; this application is useful to prevent unwanted access to the dwelling.
The wiring to enable the function is made by using terminal 13 of the 16-pin connector; it is moreover necessary
to carry a voltage of 12 V d.c. via a N.O. contact that, inserted in the lock, closes when the door is open and, at
the same time, lights up the green LED on the monitor (average additional consumption 10 mA).
Example of installation:
“Door open” signal powered with additional ELVOX power supply 6582 15 VA (13.5 V d.c.).

Lock control activation.
This control activates the lock opening relay of the door or gate providing access to the dwelling.
The command is carried out by pressing button B that sends the LOCK command to the plate which activates
the lock opening relay in the power supply; this output can pilot electrical locks at 12 V a.c. max 1 A (for example
ELVOX power supply 6948 terminals 15 – S1).
For electrical locks with greater power inputs use an external relay.
The lock command is activated solely with the MONITOR ON (self-start or call in progress).
For the wiring of the control see the diagrams in the attached “INSTALLATION DIAGRAMS AND EXAMPLES”.
Stairs light control activation.
With this command it is possible to activate the output used to control an appropriate external relay connected
to one or more lamps to switch on.
The command is activated by pressing button A that sends the CALL-F1 command to the plate which activates
the output R1 of the power supply that can be used to enable an external auxiliary relay (to be fitted).
For loads powered at 230 V it is recommended to use relays with 12 V d.c. or 15 V a.c. with output 230 V a.c.
3 A.
The stairs lighting control is always active in both operating states MONITOR OFF and MONITOR ON respec-
tively.
NOTE: The command CALL-F1 can be remoted with a N.O. push-button by using terminals 4 and 11 of the
16-pin connector.

Auxiliary Function activation.
The Auxiliary Function activation control can be used to activate external devices or services such as, for instance,
courtesy lights, automation, etc.; this is possible by hooking up a suitable external relay at 12 V d.c. or 15 V a.c.
and a contact that depends on the service you want to activate.
The auxiliary function is activated by pressing button C that sends the CALL-F2 command to the plate which
activates the output R2 of the power supply that can be used to enable an external auxiliary relay (to be fitted).
For loads powered at 230 V it is recommended to use relays with 12 V d.c. or 15 V a.c. with output 230 V a.c.
3 A.
The auxiliary function activation command is always active in both operating states MONITOR OFF and MONITOR
ON only if button C has not been configured as button 2ndf, or with the combination of buttons C+A (see
page 11).
NOTE: The command CALL-F2 can be remoted with a N.O. push-button by using terminals 4 and 12 of the
16-pin connector.

Call from outside the door.
Via the wiring of the dedicated terminal it is possible to differentiate the sound of a call from the button outside the
door (for example, landing, secondary entrance, etc.) to distinguish it from a call from the outdoor station.
To differentiate the call from outside the door the corresponding input (terminal no. 9) is used on the 16-pin con-
nector and the voice unit line dedicated to outside the door (terminal no. 2).
Alternatively, this input can be used in the “DOORBELL” configuration using a N.O. push-button connected to
terminals 9 and 5 on the 16-pin connector and setting the correct type of outside the door (see page 10).
For more details see the “Main Configurations” and “Installation Examples” section.
