x10 technology

Post by npd5 » Mon Aug 19, 2002 7:07 am

Looking for information on x10 technology….. Would like to build a transmitter , receiver and have software control it…. But researching information only results in products for sale. Any suggestions on links or projects that will help would be appreciated

X10 website itself has one app note on Tansmission theory.
http://www.x10.com/support/technology1.htm<p>They also offer a RS232 compatible transmitter reciever at http://www.x10.com/products/x10_tw523.htm<p>A PDF app note with schematic (a link) can be found on that page (above) look for "Download the technical information"

Here is another link<p>http://www.smarthome.com/bookvid.html
this has some books like the "X-10 hackers secrets vol 1" and x-10 applications guide" as well as a few other technical books on the subject.<p>Search "home automation" on a search engine then look at the support/technical sections of the sales websites for links and app notes

BSR in England was the originator of these devices. <p>X-10 is the US equivalent of the retailer. <p>All the original info used to be available on the web under BSR.<p>

BSR was the original company but that morphed into x10 for corporate identity. They later earned (well earned) the reputation of being the largest buyer of pop-up ads on the internet. remember that stupid wireless camera that you were supposed to use to protect yourself from those intruding nubile nymphets? <p>X10 is not the most reliable protocol in the world and is very suseptable to power line noise from motors and flourescent lights. Some computer power supplies are nasty too - I had one PC that killed X10 transmission when it was on, even with a filter. All in all, it works about 95% of the time. That last 5% is maddening<p>Here's a very nice little app note from microchip. http://ww1.microchip.com/downloads/en/A ... 00236a.pdf It is all-singing, all-dancing but you don't have to build all of it. I think their filters can be simplified but haven't spent any time on it.<p>I would not go to the x10 site as it's just a huge marketing promotion engine.

As far as the x10.com site goes I have had very good service and there tech support has been good as well.They sell units that will use your switch closure to send an x10 signal and a companion unit that has a relay output. There are also units that will put your code on the line if you are a more capable user.
YOu might be able to "roll your own" but chances are that you will have better success hacking the x10 products and making them into what you want rather than starting from scratch. Putting signals on that nasty powrer line can't be easy.
x10 products are not very dependable especially the ones that use wireless interfaces.
