1. A remote control transmitter and a remote receiver, the transmitter comprising:
- means for transmitting a coded signal to a remote receiver;
control means for controlling the operation of the transmitting means;
means for activating the control means;
a first code generator electrically coupled to the control means and generating a first code for the coded signal;
a second code generator electrically coupled to the control means and generating a second code for said coded signal; and
the control means including means for automatically selecting between said first and second codes including means for comparing the first code with a third predetermined code, and selecting one of the first and second codes based on the comparison for exclusively transmitting the selected one of the first and second codes within the coded signal upon each activation of the control means.

Abstract
A remote control transmitter capable of transmitting a coded signal for actuating a device connected to a remote receiver. The remote control transmitter includes a controller which actuates a transmitter element upon each activation of an activation switch. A first code generator generates a first code and a second code generator generates a second code. The controller automatically selects one of the first code and the second code for transmitting within the coded signal. The first and second codes are generated by multi-positionable switches, a serial data device, a code key memory or by rolling code encryption.

10. A method of automatically selecting between a first code and a second code to be transmitted in a coded signal from a remote control transmitter, the coded signal capable of actuating a device connected to a remote receiver, the method comprising the steps of:
-
a) reading a first code provided by a first code generating device; b) comparing the first code to a predetermined pattern and determining whether the first code matches said predetermined pattern; c) selecting the first code to be transmitted if the first code fails to match the predetermined pattern; d) selecting a second code to be transmitted if the first code matches the predetermined pattern; and e) transmitting the coded signal containing the selected one of the first code and the second code from the remote control transmitter. - View Dependent Claims (11, 12, 13, 14, 15)
