PLC's have communication ports that can be configured to talk all kinds of protocols. One of the most useful in home systems is the ASCII In/Out non-sequence protocol.
A Better X-10 Interface
In the end, Parks Associates believes that the PC and standalone consumer electronics platforms will both play key roles as distributed hubs in the home. Reprinted from the November 17, 2002 edition of "Parks' Points"
Xantech has been in this business for years and their products are high quality and reliable. If you have any wiring skills at all there is no problem setting this stuff up. If you're not comfortable with that ... just call in a home systems dealer / installer and get them to do it for you.
Both technologies will be better positioned to thrive if coexistence schemes currently being developed are broadly implemented. In addition, cost-effective combo 802.11/Bluetooth solutions should play an important role, as there are clearly situations where device vendors ideally need to support both technologies in a single host device for different applications.
A typical day in the life of a home automation system controller ... as seen through it's eyes ... if it had them that is!
Many features are controlled from one MM-443 Magicmodule Programmable Controller. There is room in the programmable memory to do other tasks that may be unique to your application. At Halloween I use a Magicmodule and MV-480 Voice Annunciator to really give the neighborhood kids a scare as they walk up to my front porch.
One of the nicest features is the cable management system which consists of velcro strips across the complete width of each shelf. This allows you to get everything wired and functioning and then zipped up tight so you can see through the quagmire and show off your wiring skills to your friends and neighbors.
The first pre-802.11g products are anticipated to be available in early 2003, although they may have interoperability issues with the eventual, final version of the standard. Pre-802.11g products will likely debut at prices fairly higher than what consumers can purchase 802.11b products for, so the question becomes how much of a premium will the market allow for these new, higher rate products?
Your final determination relies on a variety of factors including budget, functionality, upgradeablity, expandablility, confidence in installer and manufacturer. The major decision is to find a qualified systems integrator who can assist in making these determinations. The more experience or knowledge of a large variety of systems will give them the ability to offer a system designed just for your needs.
Here's a rule of thumb: If you need a keyboard to run the system, you're in trouble. Preparing your tax return is a task-oriented application that's perfect for a PC. But turning on the lights should be as simple asâ€¦turning on the lights.
Overall I must say that the system is working very well for us. There is virtually no noise from the fan at all (if you open the cabinet door you can hear a slight air flow sound from the outlet). The sensor controls to setpoint without a problem. 32 watts is less that a light bulb in power consumption so that's not an issue either.
HomePlug has eliminated problems that have plagued powerline networking in the past. No longer do common household electrical appliances like hairdryers that generate electronic noise capsize a powerline network.
You know about the advantages of X-10 Home Automation, but don't want to have bulky plug-in modules in your wall outlets? You want to have your existing wall switches work with X-10 home automation, so that style and colour is no longer limited to X-10 tooling and color white only? Then it might be interesting to take a few minutes to read this story about Marmitek MicroModules
