DTMF-12 voice dialing control module phone phone remote decoding module

Fully compatible with DTMF-12CHREV10 module

Default delivery: 12-way interlock low-level output

The module can control up to 12 low-level output or high-level output (customer contact optional)， the factory default is interlocked low-level output control， in order to improve the driving ability output level is through Schmitt trigger shaping After the output， so the output level control more reliable and stable! Output drive current of about 5.2mA， and in J1 15 feet leads to the STD interrupt low-level trigger signal to facilitate the user directly with the microcontroller used.

The module also has three operation modes: "Jog"， "Self-lock" and "Interlock". In J3， it selects self-locking and interlocking. If the user needs "Jog" Online customer service contact. Perhaps some users do not understand how these three work， in fact， and ordinary 315M， 433M and other wireless remote control is the same， our products are used to replace their ordinary mobile phone remote control， greatly improving the safety of remote control! In this brief description of the three work methods:

Jog: When press a button on the remote control， the corresponding output all the way to the output; when the release of the remote control button， the corresponding output on the disconnect. Please note that this module to achieve "Jog" function is to press a key， corresponding to a road output; and then after a certain time delay after the automatic disconnect， which is different from ordinary wireless remote control， but the function is the same .

Self-locking: that is， with a single key to control all the way， press an open， then a close， can be independently controlled， can also have more than off. Such as: When the phone by a key， the first module of the road there is an output， and then press the 1 key， the road to disconnect; another example: When respectively， press the 123 ..... key， the module corresponds to 123 ..... have output.

Interlock: Press a button， the module corresponds to a way to output; then another button， the corresponding output， before the output of the road is disconnected. It has a unique relationship， each time only by the way that the output， before the disconnect. Such as: press the phone 1 key， the first road output， press 2， the second road output， the first road disconnected.

This module J1 J2 J3 socket pin function description

J1 ---- is the power input and 12-output， 15-pin 2.54mm pitch pin header.

1 foot: positive power supply 5V

2 feet: the power supply negative Gnd

3 feet to 14 feet: 1 to 12 are the way the output

15 feet: STD external output interrupt signal， when there is output pin output low， after a period of time to return to high.

J2 ---- is the expansion of 16-output， 8-pin 2.54mm pitch pin header.

1 foot: 13 road output

2 feet: 14-way output

3 feet: 15-way output

4 feet: 16-way output

5-8 feet: standby

J3 ---- is the work of remote control output options， is 3-pin 2.54mm pitch pin header.

When the first and second feet are connected: "interlock" work

When connected to pins 2 and 3: "Self-lock" operation
