I recently saw an Ad. for a book claiming to describe the installation of the CEBus in a house (price: $149.00!!). What is the CEBus? Where can I obtain detailed information at a reasonable price?

It is a SLOWLY evolving standard for using home wiring for communications between appliances, security, computers, sensors, ... in a persons home. Their are seperate physical standards being developed for twisted-pair, coaxial (cable), fiber (big bucks ;-)), and power-line (AC wiring). Ciarcia's Circuit Cellar magazine (around Nov-89 to Jan-90) had a fairly good article on it and what it is attempting to provide. I've been scanning this and a few other consumer newsgroups for more information on actual equipment, but have not seen any so far. I know that there are some "MAC" level chips available on the market from TI (and some partner I cannot recall right now), but these were being produced before the MAC and other layers were standardized. I seem to recall that they were hoping for a complete standard, with the exeption of the fiber interface, sometime around this summer. If anyone else has more info on available devices/experimenter's kits, I'd like to know also... As to the price of $149.00 for a book, it sure had better some hardware with it as the standards can be obtained for much less. ----------------------------------------------------------------------------- Chip Boling | | (205) 730-6297 Intergraph Corp.

What is the CEBus? Where can >I obtain detailed information at a reasonable price? The CEBus is the EIA (Electronic Industries Association) Home Automation Standard Consumer Electronic Bus. I posted a request to the net (sci.electronics) about a week ago, asking whether anybody knew the status of the Standard, but I haven't had a response yet !!! The CEBus has various types of media : power line, twisted pair, coax, infra red, radio freq., and fiber optics. To date, the only info I have is a draft interim Standard from the EIA (document EIA IS-60), which was released for balloting. It only addresses the power line media, but describes Data Link Layer, Node Network Layer and Application Layer (the CEBus model is based on OSI). I was particularly interested in finding out more about the twisted pair media, and had asked whether anyone out there knew whether the physical layer had been defined. As I said : no response. You can get info from the EIA at a reasonable price I understand (it's under the $50 mark), but I wish you good luck. I've been trying to get the info from the EIA for some time now, with no success. Maybe the EIA doesn't want to talk to us Aussies :-) If anybody can shed more light on the subject, I'd appreciate. I'm interested in any information, even if it is only interim. Email me, or fax me or post here !

I'm >interested in any information, even if it is only interim. Sorry, but the only thing I can offer is that I saw a TV show (possibly a news segment?) that showed someone who had a hand in coming up with the schema and his house which was completely wired for CEBus. It showed how his entire house was wired on the bus. His shutters opened with the sunset; you could see who was at the door from the TV, the toaster and coffee maker were synced to the alarm clock; the oven flashed a message on the TV when the roast was done, etc, etc, etc.... -- Dennis Lou Disclaimer: I don't use lame disks. dlou@dino.ucsd.edu "But Yossarian, what if everyone thought that way?"
