Touch Tone (DTMF) Reader

Touch Tone (DTMF) Reader

Dialed phone numbers, repeater codes, control codes, anywhere touch tones are used your TG2 will decode and store any DTMF tone it hears. A simple hook-up to any radio speaker or phone line is all that is required. The Flash storage capacity of the built-in micro controller allows the circuit to store 640-digit numbers for 10 years, even with the power turned off. The bright 8-digit display lets you scroll through the stored numbers at your leisure. To make it easy to pick out numbers or codes, a dash is inserted between any group or set of numbers that were decoded more than 3 seconds apart. Added features include an onboard RJ11 phone jack for easier phone line interfacing and an output latch jack offering an external trigger source when a user specified number ( 1 to 60 digits) matches the monitor input. The TG2 runs on any 8 to 15 volt DC power source and is both regulated and crystal controlled for the ultimate in stability. Click on photograph for more information.
