ADRESSES
Up to a maximum of 256 different addresses can be preset. These are subdivided into a so-called
HouseCode (A to P incl.) and a UnitCode (1 to 16 incl.). The HouseCode can also be set on the
controllers, so that the controllers and modules become part of the same system. The address
can be set either using code dials or by pressing buttons, depending on the type of module.
The Marmitek X-10 System uses standard commands, which control all units with the same
HouseCode at the same time (e.g. all lights on, all off, etc.).
SIGNAL RANGE
Range of Marmitek X-10 signals over the Power Line and how to increase the range.
The Marmitek X-10 System is based on power line communication. The range of the Marmitek
X-10 signals very much depends on the local circumstances. On average the range is a cable
length of 80 meters.
If you have difficulties with the range of your Marmitek X-10 signals, please pay
attention to the following facts:
1. When more than one phase is used for your electrical system, it is necessary to couple these
phases for the Marmitek X-10 signals. For coupling you can use FD10 Phase Couplers/Filters.
You only need to install a Phase Coupler/Filter when your wall outlets and light switches are
divided over more than one phase (more than one group is no problem). For bigger buildings
or longer distances we advice you to use an active repeater instead of passive FD10’s.
2. It is possible that Marmitek X-10 signals are attenuated by devices and lights which are
connected to the power line. In a normal home situation this effect is negligible (the Marmitek
X-10 system is using active gain control to eliminate the effects). However, it is possible that a
particular device in your house is attenuating the signals so much that the range of Marmitek
X-10 signals is decreased significantly. When you have range problems, it is wise to try to locate
the device which is attenuating the signals simply by unplugging devices from the power line,
and testing the differences in range for your Marmitek 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 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.
