Garage Door question - Rotating Codes
From the Internet and other sources, I think I have a partial
understanding about how rotating code remote controls (like garage
door openers) work.
I understand that multiple remotes must be registered to the central
receiver and the codes advance according to a pre-programmed
algorithm.
What happens though if the remote control button is advanced multiple
times when it is out of range of the receiver? I would think it would
get out of synch and eventually cease to function.
Does the receiver accept a range of codes? (Say the last 10 codes or
is it some other number).
How does the receiver stay in sync with the transmitters?
