VIDEOPHONE ADDRESS – SW1.1..7
SW1.1..7
The table below shows how to set the address of the videophone. Considering that ON = 1 and OFF = 0, multiply
each digit for the relevant decimal weight then sum values obtained to get the address: E.g. as highlighted in the
table OFF,ON,OFF,OFF,ON, OFF,ON in binary is equal to 0100101 then multiplying each digit for the relevant dec-
imal weight you obtain the address that is 37.

VIDEOPHONE END OF LINE TERMIANTION –JP1
Looking at the videophone from the rear:
JP1
Move the jumper
JP1
to the lower posi-
tion to enable the bus termination.
JP1
Move the jumper
JP1
to the upper posi-
tion to disable the bus termination.
In case of more units (intercoms, videophones or video monitors) in a parallel connection (bus wires are connected to the terminals
of the first unit then from this to the second and so on up to 4 units max) the BUS termination must be enabled only for the last unit
in the chain while on all other units it must be set to disabled.
INTERCOMMUNICATION MODE – SW3.1
SW3.1
This switch establishes the intercommunication mode: in OFF position (default) intercommunication is between units
in the same apartment (same addresses but different extension); in ON position the intercommunication is between
units in different apartments (different addresses).
On installations where there are more than one intercom/videophone in the same apartment and intercommunication
between different apartments is required, only one intercom/videophone may be set with this function (SW3.1=ON,
SW3.2=OFF, SW3.3=OFF). The other intercom/videophones in the apartment must be set for local intercommunication with
extension addresses “2-4” (slaves). From the intercom/videophone set for intercommunication with other apartments it
will not be possible to intercommunicate within the apartment but slave extensions 2-4 will be able to intercommunicate
with each other within the apartment.
EXTENSION NO – SW.2..3
SW3.2..3
If the intercommunication between apartments is enabled (switch 1 of SW3 = ON)
leave these two switches in default position (both to OFF). Otherwise, if the inter-
communication is between the same apartment (switch 1 of SW3 = OFF), set the
extension addresses starting always from 1. During the external call, all video monitors in the same
flat will ring but the video will be shown only from the videophone with extension address 1.
SLAVE MODE - SW3.4
SW3.4
This set up concerns the answering mode of the video monitor when there is more than one unit (max 4) in the same
apartment. OFF (default) = during a call, only the video monitor with extension 1 (master) will show the video. ON =
the video monitor will be switched on independently of the extension address: in this case the video monitor must be
supplied locally using a power supply Art. 2321 and connecting respectively BUS+ to teVAUX and BUS- to terminal GND on
the connection terminals (the local power supply is required for each black & white slave videophone or starting from the third slave
videophone when they are all colour videophones).
If you set for one slave videophone, you must set ON the same switch also for the relevant master videophone.
