ESVK/6788 Series "2 wire Bus" videokit
Art. 6788
7" colour display videophone
EXTENSION NO – 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 in-
tercommunication 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 vide-
ophone with extension address 1..
SLAVE MODE - 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 or Art. AMR-12, see notes on 12M and VA on "Connection Terminals
Signals" table (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..
NOTE: WHEN USING CST2310 CONCIERGE

calls from the concierge; on the master device (SW3
Dip 2&3 OFF), set dip switch 1 of SW2 to OFF and
also dip switch 4 of SW3 to ON. Intercommunication
