Technically, you shouldnt need a phase
couple or 2 controllers if X10 worked as
advertised. one posible cause it doesnt
jump or make it to a far off module is due
to the limitted range or voltage produced
by the CM15A.
NOW... the CM15A has some interesting
problems that are done on purpose.
It has been found that the CM15A has an
output voltage of only 1.7V, CM11A has
2.4v - 4.5v as with a repeater aprox. 3.3v -
5v.
A lower voltage will not make the distance
if theres any Interference. (TV, Stereo,
PC, some lights not filtered)
Not as much of a problem if all is filtered
in a brand new home with clean power.
I cant say how to turn it up, but its what
is needed to get maimum performance.
X10 is not going to turn it up or it would
void the need for other products they push
to sell you.
Also, you can make or buy a 1/4wave gnd
plane antenna and boost the RF side of the
unit as well.
The specs of the CM15A shows a 240mm
antenna. Measure that plastic thing....
inside the rest of the antenna is inside
Not going into detail but there is info
about a 1/4wave antenna on sites.
ADD the cucuit boards also acts as an
antenna, so you should / could get better
performance if you set the original antenna
horizontal from the wall. like...
