Abstract
A trainable transmitter comprises a transmitter, code-generation circuitry and a removable, plug-in data module. The data module includes information necessary for generating a code for a specific security system, such as a garage door opener. Preferably, the data includes a cryptographic algorithm and the frequency at which the wireless signal is to be generated. The code-generation circuitry accesses the data in the data module to generate a code, which is then transmitted by the transmitter. A variety of data modules are provided. A user installs a data module which corresponds to the security system to be accessed.
