| An Online Guide To Remote Controls For Electric Doors And Gates |
Fifty years ago remote controls for an automatic
garage door opener
were the size of a table radio, contained vacuum tubes, and had to be
installed under the hood of your car by a technician. And of course,
when you changed cars, you again called the tech to remove and
reinstall the apparatus.
With the invention of the transistor, transmitters
became small and
portable. Today with Integrated Circuits (ic's) and Digital Technology
Remote Control Transmitters send out very complex signals to avoid
duplication and provide increased security.
Because there are so many makes and models
manufactured today such
as Alliance, Allister, Allstar, Chamberlain, Crusader,
DeltaIII, Genie,
Liftmaster, Linear, Megacode, Moore-O-Matic, Multicode,
Pulsar,
Stanley, and Sentex and since most designs
will not interchange,
you need to order the exact unit to properly activate your system.
You need a "Guide" to help you choose
the correct product
and so we have created this Internet "GateGuide" to help.
Remote control transmitters fall into two general categories: | |
| Type 1 - |
The transmitter has a row of switches inside (dip switches) and you set the code by adjusting the switches on or off to match an identical setting in the receiver. |
| Type 2 - |
The transmitter has no internal switches, but rather the receiver
"learns" the unique code from each individual transmitter. This system has the advantage of being able to selectively add or delete individual transmitters if lost or stolen. |
