The DTD-16 Plus is a full-featured DTMF tone/sequence decoder that is user programmable to decode single tones or sequences up to six tones in length and maybe assigned to any one of eight SPST normally open relays, eight open collectors and/or the USB serial port. The relays and open collectors may 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 port equipped with Windows HyperTerminal and/or Putty.
