Abstract:
1. A method of processing received command signals transmitted from a wireless transmitter to a barrier operator so as to actuate an access barrier, the method comprising: scanning by a receiver in at least one of two ways to detect a command signal frequency wherein said scanning can be done in an initial use mode, a scan all mode, and a scan stored mode by selectively actuating a scan button; wherein in said initial use mode, said receiver checks one of two frequencies and sets said receiver if data is received on one of the two frequencies; wherein in said scan all mode, said receiver checks a number of frequencies and sets said receiver if data is received on one of said number of frequencies; and wherein in said scan stored mode, said receiver checks previously stored frequencies and sets said receiver if data is received on one of said stored frequencies; setting said receiver to receive said command signal at a detected signal frequency; receiving at said receiver said command signal which includes a function code data word associated with a function to be performed by the barrier operator; determining whether a data format of said function code data word is stored in said barrier operator; determining whether any portion of said function code data word matches one or more fixed code tags if said data format of said function code data word is not stored at said barrier operator; and carrying out the function associated with said function code data word at the barrier operator if a match is made at said second determining step.
