The DT-232 is an inexpensive dial-up remote control with amazing capabilities! It gives you DTMF access to four, user programmable relays that can be momentary, latching, etc. Relays can be programmed to respond to any DTMF tone or sequence.
The DT-232 can output serial data, in your user-defined format, so it can interface to virtually any piece of hardware that requires serial control or input. The DT-232 receives DTMF tones from either its audio input connector or from its built-in telephone autocoupler. The DTMF tones are converted to, user defined, ASCII data & transmitted to the host computer or remote equipment.
In addition to receiving DTMF tones, the DT- 232 can accept ASCII input from itâ€™s serial port and generate DTMF tones that are transmitted to a phone line for controlling equipment in remote locations.
Telephone audio is passively coupled to the audio jack for remote broadcasting.
A free Windows program makes control and programming incredibly simple. You can also operate the DT-232â€™s basic functions from any terminal program on almost any type of computer. The free software Lets you upload, download save your DT-232 configurations. Software is required for the advanced programming functions.
