4 Conguration, conductor lengths
Single line system with bus distributor
Conductor length with bus
distributor
If the use of bus distributors is nec-
essary for installation, in addition to
the maximum range, attenuation of
the bus distributors and conductor
material must be additionally taken
into account.
The following information relating
to conductor lengths refers to one
camera branch and one monitor
branch. If several branches are
installed within a line, the informa-
tion is applicable to each branch.
Whichever value (attenuation or
conductor length) is reached rst is
applicable as a specication of the
admissible value.
Conductor length
Conductor material J-Y(St)Y cable
with 0.8mm diameter:
• max. 150m from the bus video
line rectier to the most distant user
in the monitor branch
• max. 150m from the bus video
line rectier to the most distant user
in the camera branch
• max. 45 dB attenuation from the
most distant user in the camera
branch to the most distant user in
the monitor branch
With a core diameter of 0.6mm,
the range is halved.
The maximum admissible attenua-
tion is 45dB within a line. General
rule for J-Y(St)Y cable material:
• 10m conductor length corre-
sponds to 2dB attenuation!
Within the line, the maximum length
of the conductor material must not
exceed 1,500m.
If the maximum admissible atten-
uation of 45dB is exceeded, the
bus video line rectier accessory
ZBVNG650-… must be used in the
BVNG650-… to compensate for
this loss.
Signal transmission
Only signals from the In-Home bus
may be transmitted over the laid
conductor material. No additional
transmissions, for example PBX
extensions of a telephone system, S0
Bus (ISDN) or data lines of an alarm
system in the same cable.
The camera branch and monitor
branch must be laid separately and
must not be located in the same
cable. This can result in disturbance
to the picture composition.
Terminating resistor
Transmission of signals within Siedle
In-Home: Video takes place using
high-frequency technology.
In order to avoid disturbance on the
bus cores, the end of each monitor
branch must terminated with an RC
element. The RC element comprises
a resistor with 100Ohm and a
capacitor with 1nF. In its as-deliv-
ered status, each bus telephone with
colour monitor has a small tted
circuit board with this terminating
resistor at output terminals TaM/
TbM.
J-Y(St)Y
Camera branch 1 max. 150 m/492 ft
Monitor branch 1 max. 150 m/492 ft
Camera branch 2 max. 150 m/492 ft
Monitor branch 2 max. 150 m/492 ft
Total attenuation max. 45 dB
