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 cou-

ple 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 sig-

nals 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 atten-

uating 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
