I have built 2 PCB's which connect an RS232 wireless through 434mHz and
I want to connect PCB2 (both PCB's are exactly the same) to the CM11a
and the other to my networkserver. If I connect the PCB2 to the CM11a
1:1 nothing happens. If I connect the PCB1 to the CM11a and ...

I need an on/off X10 wall switch only (no dimmer).  I have found some
in the decorator style.  I need 3 or 4 in the non-decorator style.
Has anyone found these or know where I could get a few.  I want to use
them for fans and a fireplace switch.  However, I can't go to the

Hi, I was wondering if there was any command in the X10 controller
(CM11A) that could allow me to power cycle or reset it?   Sometimes
the controller gets stuck in a funky state such that it cannot accept
any more commands.   This is fixed by turning the controller on and

Security system model DS7000 with 3 door switches and 4 motion detectors. I
can Install the 3 door switches and 3 of 4 motion detectors, the system arms
ok. But when I add in the 4th motion detector I can't arm it. I tryed
installing each part one at a time and arming the system ...

Hi, I have a security system that was installed by an alarm vendor who
have since gone out of business. The Power832 controls 8 zones, and
has two of the PC5508 LED keypads. They left a PC5500Z LCD keypad to
be installed, but never did.

I've had a few days to test the CM15A interface and ActiveHome Pro, and I'd
like to provide some feedback to the group.
CM15A Drivers:
In earlier posts I've read that the installation of the CM15A drivers can

Hey, I'm about to install my CR234 (coupler/repeater).  I'm lucky
enough to have a 220V outlet (both phases plus ground -- an appliance
outlet) right next to the breaker box, on its own circuit.
Can I just wire up the CR234 to a 220V (three-prong male) plug and

I've figured out all of the signals to/from the Cypress controller with the
exception of pin 15. It connects to the collector of TR1. It looks like it
has something to do with detecting when the batteries are the power source
but it appears to be at 0V at all times.

I have a couple of panel heaters (see www.eheat.us).  I like the
heaters, but here is my problem.  They do not have built in
thermostats.  So there is no way to regulate room temperature.  Right
now I have the heaters attached to a timer so it comes on at night and

I ask this question as a newbie to Home Automation, but coming from a
background of commercial building automation (I work for a major OEM in that
area).
In the commercial world, there's virtually no market penetration of X10-type

I'd like to control my low-voltage outdoor lights with X-10.  They're
powered by a 200W 24V transformer.  (It's an "electronic" transformer -
not sure what this means, but it doesn't work until it's delivering at
least 50W or so.)  I'm currently drawing about 80W on it (four 20W

I have a DVR card that will allow control of a pan tilt camera.  I
don't have the $$$$ it cost for this type of camera.
Has anyone "homebrewed" a pan tilt zoom camera using another more
affordable method of either servos controlled by the DVR or a

Not sure if this is the right newsgroup to post..
Anyone knows where to buy this Rex Plus thief deterrent device in Toronto?
or even a Canadian web site? (wanna lower the shipping and duty if possible)

I'm starting my X10 design so nothing is installed yet.  I have ground fault
interrupter outlets installed in both bathrooms.  Will these outlets affect
X10 signals in the same way that a surge protector will affect X10?  There
are some circuits downstream of the outlets where I'd ...
