Abstract

A system for receiving data for training a trainable transmitter used to subsequently transmit a modulated RF signal having the received data includes an antenna, a capacitive detection circuit and a control circuit. The capacitive detection circuit is coupled to the antenna and configured to detect data provided in a control signal of a remote control transmitter used to remotely actuate a device. The control circuit is coupled to the capacitive detection circuit and is configured to store the received data and to generate the RF signal having the received data to be transmitted by the trainable transmitter to actuate the device.
