from the power line, and testing the differences in range for
your Haibrain system. When e.g. your conclusion is that e.g.
your computer monitor is attenuating the signal, you can use a
FM10 Plug-in Filter between the power line and the monitor to
eliminate the effects.
Known devices which can cause attenuation are:
PC Monitors
PCs with heavy internal power supplies
Old Televisions
Copiers
Fluorescent Lights
Gas Discharge Lamps (Energy Saving Lamps)
3.
Some (old) devices are able to disturb the signal by transmitting
noise on the power line. Because the Haibrain X-10 signals are
transmitted on 120 kHz, only noise on or near
this frequency
will have influence on the range. When you use a FM10 Filter
to connect this device to the power line, the noise will be
filtered.
4.
The Haibrain X-10 protocol has several mechanism to avoid
modules to be switched on or off by other sources than your
Haibrain X-10 Controllers. However, it is possible that the
Haibrain X-10 signals are disturbed by e.g. baby phones which
a
re in TALK mode (continuous transmission). When these kind
of signals are present on the power line it is possible that the
Haibrain X-10 signals will not come through.
5. The mains do not stop at the front door of your home.
Everything that is attached to mains nearby your home can
have influence on Haibrain X-10 signals (e.g. heavy machinery).
If you think that your system is influenced by devices out of
your house, it is advisable to install FD10 Phase Coupler/Filter
on each phase entering the house. These filters will block
signals coming into or going out of your house, but
will also
match the impedance for the mains. The FD10’s will not only
filter but will also couple the phases (please see 1). To couple
the phases use a CAT 3000, see point 1 above.
