Use Method:

This is the DTMF o controller with four channels, any phone or fixed telephone with DTMF key code remotely controls product relay "open" and "close".(the majority of smartphones and functions machine are DTMF code). Our software "DTMF Dial" (installed in a computer) can be also provided to control relays.

AD22A08_7 As shown above, by phone remote control relay. You need two phones, one as a receiver (phone_1), the other one as a transmitter (phone_2); mobile phone_1 connected by DTMF o cable 3.5MM o controller (the controller to be powered), and then using phone_2 ( may be a fixed telephone) call the phone_1, phone_1 answered, so that two phone call each other; then dial 1/2/3/4 by phone_2 keypad to control four relays .

As shown above, you can install one of our "DTMF Dial" software in your computer, through the software control DTMF o controller. At first, use 3.5MM o cable to the computer video port and o port controller, then click on the software to control relays 1/2/3/4.

Caution:

1 DTMF o 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 o interface, the transmitter can be a cell phone or landline

3 as a receiver of the phone or a computer installed the "DTMF Dial" software must output a sound (not muted), or they will not control relays.
