Rolling Code Vs. Fixed Code RF Remote Control
Remotes control send signals in code. When the sending code is the same as the code which is expected by the receiver, the relay will switch and the door, barrier or car will open. Remote controls with a fixed code will always send out the same code. A rolling code (or hopping code) always send out a different code from the one previously sent. The code changes every time because of the algorithm which is part of the remote control.

Famous quotes containing the words rolling, code, fixed, remote and/or control:
“The Concord had rarely been a river, or rivus, but barely fluvius, or between fluvius and lacus. This Merrimack was neither rivus nor fluvius nor lacus, but rather amnis here, a gently swelling and stately rolling flood approaching the sea. We could even sympathize with its buoyant tied, going to seek its fortune in the ocean, and anticipating the time when “being received within the plain of its freer water,” it should “beat the shore for banks.””
—Henry David Thoreau (1817–1862)
“Wise Draco comes, deep in the midnight roll
Of black artillery; he comes, though late;
In code corroborating Calvin’s creed
And cynic tyrannies of honest kings;
He comes, nor parlies; and the Town, redeemed,
Gives thanks devout; nor, being thankful, heeds
The grimy slur on the Republic’s faith implied,
Which holds that Man is naturally good,
And—more—is Nature’s Roman, never to be
scourged.”
—Herman Melville (1819–1891)
“Museums, museums, museums, object-lessons rigged out to illustrate the unsound theories of archaeologists, crazy attempts to co-ordinate and get into a fixed order that which has no fixed order and will not be co-ordinated! It is sickening! Why must all experience be systematized?... A museum is not a first-hand contact: it is an illustrated lecture. And what one wants is the actual vital touch.”
—D.H. (David Herbert)
“Oh! what a poor thing is human life in its best enjoyments!—subjected to imaginary evils when it has no real ones to disturb it! and that can be made as effectually unhappy by its apprehensions of remote contingencies as if it was struggling with the pains of a present distress!”
—Samuel Richardson (1689–1761)
“The three-year-old who lies about taking a cookie isn’t really a “liar” after all. He simply can’t control his impulses. He then convinces himself of a new truth and, eager for your approval, reports the version that he knows will make you happy.”
—Cathy Rindner Tempelsman (20th century)
