3.Operating Temperature: -40°C ~ 65 °C
4.Storage Temperature: -40°C ~ 65 °C
5.Size:40mm*30mm*10mm
6.Receive and send data through the serial port.
7.The audio cable can connected the input and output together, send data and receive data simultaneously.
8.Modules can once receive serial 30 data waiting to sent.
9.Drive Mode: Serial port communication Format: 9600 baud rate no parity, 8 bits data, 1 bit stop.
10.Module interface:
(1)Communication interface P2:
5V:power positive Interface (5V).
GND:Power supply ground interface.
RXD:module receiving side; connected microcontroller (MCU) sender TXD
TXD:module sender; connected microcontroller (MCU) receiver RXD
(2)signal input interface J1: 3.5MM audio input interface.
(3)signal output interface J2: 3.5MM audio output interface.
Feature:
1.DTMF V1 is a dual tone multi-frequency decoding encoding module.
2.Received code process:
3.5MM audio interface converts the received audio signal into a dual-tone multi-frequency code,
Converted to ASCII code sent through the serial port.
Input and output can be connected together by audio cable in this Module.
3.Code transmitting process:
Module receives the serial port input ASCII code,
Then converted to DTMF code,
And then converted to an audio signal sent via 3.5MM audio interface.
4.Application:
Remote device control;
Dual tone multi-frequency code decoding;
Dual-tone multi-frequency coding;
Note: Please do not put circuit module connects directly to the computer's serial port,Through the RS232 to TTL module, the signal converts into TTL level signals then can be connected with the circuit module,otherwisethe module will damaged.
Package:
1*Dual Tone Multi-Frequency DTMF V1 Signal Decoding And Encoding Module 5V
