They are standard Leviton 6381 2 wire X10
switches. They are listed in AHP's list of
devices. They have added features, such as
ramping up or down when receiving an on or
off command. This is Leviton's description:
deal for controlling bedroom, living room and
family room ceiling light fixtures, table
lamps or just about any switched outdoor
lighting fixture. This switch gives you the
power to turn lights on and off, plus dim
them to any level, at the switch or remotely
from any X10 transmitter. To dim the light,
just press and hold the switch until the
light dims to the level you desire.
This switch also has a unique Soft Start
feature that gently fades lights on over a
2-second span. In addition to being a very
pleasant effect, it considerably extends the
life of your bulbs. There's even a Resume Dim
feature, which returns the light to the dim
level it, was set to before the light was
turned off.
The switch also boasts Leviton's
Intellisense® AGC (Automatic Gain Control)
for enhanced response to X10 signals. AGC
adjusts receiver sensitivity to help
eliminate noise interference and improve the
performance of your X10 system.
My question still is: why do they work when
the cm15 is hooked to the computer, but not
without it, even though the cm15 seems to be
sending commands?
