Addresses.
You can select up to 256 addresses by setting two code wheels on the modules. The two
code wheels are dividing the address into a House Code ( A .. P) and a Unit Code (1 .. 16).
On Controllers the House Code is also selectable. When Modules and Controllers are set to
the same House Code they will work together.
The Marmitek X-10 System contains many standardized commands whereby modules set to
the same House Code will respond simultaneously (e.g. All lights on, all off).
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)
