Brian H (other)
You're welcome. I just came across this site
today... I don't know how new it is but it
seems like just the right thing. It's obvious
the other Brian knows this stuff pretty well too.
The SS13a has been ok here. We use several
around the house. Be aware that there are at
least two different versions internally. I
know this because I utilize their guts for
that wireless toggle switch I mentioned
below. I build working prototypes from them.
I add a second pc board to handle the
normally closed contacts of the actuating
toggle so the battery doesn't get run down.
I've been fighting the patent office for more
than a decade over the patent, and I'm still
trying. And yes, I've approached x10
numerous times - they are simply too short
sighted, their CEO telling me that "they
don't do single point controls". Hmmm.
Oh, the different versions. One of the early
so called intermittant problems which still
exists with some of the push button controls
is that the user doesn't hold the button down
long enough to finish the second
transmissions because the button also
powers up the transmitter. This included
early models of the SS13A. To find out if
your unit is of the old or new design, simply
quickly poke the rocker and see if the light
continues a bit after you remove your finger.
They basically incorporated a delay timer in
the later units that allows completion of the
transmission.
You should also be aware that the transceiver
locaton can be critical, depending on
location, line side, what's sharing the line,
and the transmitters themselves. One of
their older handhelds had a 9v battery and we
still use in one of our cars because of it's
range.
Locating the 751 in the highest location
possible also helps. Ours is in the attic of
the barn, about 20 feet up.
good luck.
