Finding the frequency for an old garage door opener
We just bought a house with old garage door openers, and the previous
owners had long since lost their remotes. The openers are old Stanley V-76 models with 8 dip-switches on the receiver. We got a new universal remote (the 'Clicker'), which claimed that Stanley models had 10 dip switches, so presumably our model is so old that Stanley changed the number of switches they used since they made ours. My question is: presumably, the nice little dangly antenna on our garage door opener will respond to the right frequency, and our new remote could be made to reproduce that frequency. But how can I match up the two? I did read that the FCC reduced the spectrum of possible garage-door frequencies in the 90's due to UHF interference or some such, but if it was just reduced, there'd presumably be some dip-switch setting I could find on my the opener that would be in the new range. Anyone? Or anyone know of a better newsgroup on which to ask? Thanks! -Lucian |

I think the switch selects different modulation sequences. |

There are instructions on how to set the 'extra' switches for an 8 bit code. N |

From my experience with older screw drive system, the 8 dip switch will work with the 10 dip switch remote by leaving the two lower or uppper switch in the off position (match the 8 and leave two highest or two lowest to off. if it still doesn't work try the two highest/lowest to both on). If this still doesn't work, then you probably have the wrong RF transmitter frequency. The ones I've dealt with are typically 300 or 320 MHz. There may be a label on the master unit saying what RF it is set to. And yes, the DIp switch does not affect RF setting. the switch is the pulse modulated signal that is sent to the receiver. |

You can purchase replacement remotes, and receivers that replace the
existing units. They work by closing the contacts of the hard wired pushbutton switch that is usually mounted by the door leading from the garage to the house.

Yay! I got it to work using this technique. I think my original problem was that the label on the old receiver said 'open' instead of 'on' or 'off' and I interpreted it wrong ('open' turned out to mean 'off'). Thank you! -Lucian |
