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 Marmitek 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 Marmitek X-10 protocol has several mechanism to avoid
modules to be switched on or off by other sources than your
Marmitek X-10 Controllers. However, it is possible that the
Marmitek X-10 signals are disturbed by e.g. baby phones
which are in TALK mode (continuous transmission). When
these kind of signals are present on the power line it is possible
that the Marmitek 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 Marmitek 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. Hereby make
your house Marmitek X-10 compatible for these units. To
couple the phases use a CAT 3000, see point 1 above.
