Use Method
This is the DTMF audio controller with four channels, any phone or fixed telephone with DTMF key code remotely controls product relay inchopeninch and inchcloseinch.(the majority of smartphones and functions machine are DTMF code). Our software inchDTMF Dialinch (installed in a computer) can be also provided to control relays.

As shown above, you can install one of our inchDTMF Dialinch software in your computer, through the software control DTMF audio controller. At first, use 3.5MM audio cable to the computer video port and audio port controller, then click on the software to control relays 1/2/3/4.
Caution
1. DTMF audio controller must use stable work of DC 12V power supply (recommendations 1A or above the power adapter)
2. remote control the controller by a mobile phone, the receiver must be the phone with 3.5MM audio interface, the transmitter can be a cell phone or landline
3. as a receiver of the phone or a computer installed the inchDTMF Dialinch software must output a sound (not muted), or they will not control relays.
