Couplers and Amplifiers (The heart of the system)One thing that most people try to get by without is a coupler or an amplifier/coupler. A coupler is a device that connects both phases of A/C voltage in your home. An amplifier/coupler is a device that amplifies the X-10 signal up to 20 times and also couples the phases. In most applications at least one of these is needed to insure X-10 signal completions. The X-10 you install may work fine for a few days, weeks or even months but chances are, you will have missed commands unless you have a coupler or amplifier/coupler. The amplifier/coupler is the best, and most expensive choice but is the most desirable. The problem with the passive, or non-amplified coupler is it has to cut the signal in order to cross it over to the other phase of voltage. This is not a desired alternative as you can figure. At least one of these devices should be installed in your home. On a side note, it has been said that a .1-microfarad capacitor installed between the phases will improve the coupling of X-10 signals. I have not tried this but sources say that installing a .1 240 volts or higher rated capacitor in the dryer (if it’s 240volts) helped there X-10.
X-10 FiltersFilters do just what they sound like they would. They install between noise producing devices to clean up the noise they produce. Most of today's electronics have “clean” power supplies in them. In order for them to be clean, they must put the garbage, or noise, somewhere. This noise is reintroduced into the power lines of your home. This noise has to be cleaned up to allow the X-10 to function properly. Installing a filter in line with a noisy device can do this. These filters can absorb the noise and clean up the electrical lines in your home. There are two easy to find filters available. One is rated at 5 amps and the other is rated for 15 amps. The 5 amp is a plug in style while the 15 amp is an in line model. The inline can be placed into a project box and have ends placed on it for easy installation. If you are unsure of the rating you need, here is a quick guide. If you know the wattage of a device, device it by 110 to get the amperage it draws. Example: A computer that draws 400 watts would need about 3.7 amps of current. This does not include any surges at power up so factor a little extra in there. One question I have is, how effective is a surge suppresser is a filter is installed in line with it. I know most companies like Panamax, will not honor warranties if the surge suppresser is not installed to there specifications.
In ClosingI hope this helps anyone who has any questions about X-10. X-10 is a safe and fun way to create a Smart home. If you choose to endeavor into X-10, PLEASE use caution when installing electrical devices. Although 110 volts will probably not kill you, it can hurt you real bad.
