DTMF decoder connected to a Cell Phone (Mobile Phone). The phone auto answers an incoming call and feeds the receive audio to the DTMF decoder, Morse confirmation tones are fed back into the phone's microphone input.

DTMF control sequences are sent to the DTMF decoder from the calling phone's keypad, for example 12340* to turn the relay on.

The DTMF decoder used in this demo is available from our website: www.cstech.co.uk

The 4 pole 2.5mm plug for the Nokia is also available from our website.

Please excuse GSM buzz on audio track, the Camcorder was very sensitive to the mobile's transmitters.
