Re: Issue Touch Tone (DTMF) via control system

Thanks for the input. I will look at both approaches. Chris, your approach is particularly intriguing. I'll probably tinker with that first.


Thanks again!!

Ive got a gate to control that has momentary contact closure inputs to both open and close the gate. But the phone system is tied to the gate and from the phone system, you have more control. By pressing the following buttons:

1 = open (closes after 30 sec)
2 = open for 30 min
3 = Close
4 = Open indefinitely until the user closes it from phone system

The gate seems to be sensing the touch tone from the phone system to determine its behavior. The problem is, if the gate is open indefinitely or for a 30 min stretch, my little momentary contact closure from the control system won't close the gate.

I am looking for a widget that can issue touch tones (at least buttons 1-4)
