The DTD-16 + G2 is a full-featured DTMF tone/sequence decoder that is user programmable to decode single tones or sequences up to six tones in length which can be assigned to any one of eight SPST normally open relays, eight open collectors and the USB/RS-232 serial ports. The DTD’s relay and open collector outputs can be programmed to close for the duration of tone, pulse immediately after completion of detection, wait a programmed (up to 9.99 seconds) length of time after detection, or latch/unlatch. Programming is performed using a non-dedicated PC’s USB or RS-232 serial port equipped with a serial terminal program like HyperTerminal, Tera Term, or PuTTY.
