Abstract:
1. A method for enabling receipt and storage of data by a movable barrier operator from a plurality of transmitter devices, each transmitter device maintaining a transmitter code and a unique serial number, each transmitter device having specific operational features, the method comprising: designating a number of records in a memory array maintained by the operator; sub-dividing said records into at least two groups, wherein each group is associated with the transmitter devices having the same operational features; associating a predetermined number of binary bits with each of said records; designating by the operator one of said bits as a validity bit, and some of the remaining said bits as transmitter bits; receiving a transmitter code from one of the transmitter devices by the operator; sequentially comparing said transmitter bits of each said record with said transmitter code; determining whether said transmitter bits of one of said records matches said transmitter code, wherein if a match occurs at said determining step, said validity bit associated with said record is set as usable and said transmitter serial number is associated with said record.
