LC12S UART Wireless Serial Transparent Transmition 128 Channel Module

                                            2.4G LC12S 120m UART Wireless Serial Transparent Transmition 128 Channel Module

This module for the old LC12S upgrade, an increase of external antenna pins and function indicator, better performance than the old version, the use of the same in the old version 

First, the introduction 

• LC12S uses the latest 2.4G SOC technology, is characterized by free development, line of sight 120 meters, send and receive one without switching, transparent serial port 

• Lose, offer the communication agreement, can debug quickly success. As long as users understand the serial communication, without the complexity of wireless communication knowledge, can be completed without 

• Development of line communication products. 

Second, the characteristics 

• Half-duplex communication, anti-interference ability 

• 2.4GHz ISM band, 128 channels adjustable, no need to apply for use 

• Supply voltage: 2.8-3.6V, the maximum output power of 12dBm 

• Receiving sensitivity -95dBm 

• Launch working current 40mA @ 12dBm 25mA @ 0dBm 

• Receive working current 24mA 

• Sleep current 8uA 

• Standard TTL level UART serial port 

• Working frequency can be set, multiple modules frequency division multiplexing, do not interfere with each other 

• Communication protocol conversion and RF transceiver switch automatically, users do not need to interfere, easy to use 

• Communication speed 0.6kbps-38.4kbps, users can configure by AT command 

• Transmission distance, open without interference up to 120 meters 

• Small size SMD package, no antenna, easy installation 

• Third, the application areas 

• Remote control data acquisition intelligent home industrial control robot smart appliances

Data Format :

Host sends: 0xaa + 0x5a + module ID + network ID (ID must be the same) + 0x00 + RF transmit power + 0x00 + serial port rate

+ 0x00 + RF channel selection + 0x00 + 0x00 + 0x12 (byte length) + 0x00 + and check byte

Note: Checksum = all bytes accumulated

Module answered successfully

E.g:

Host sends: AA5A0000000000000004000A000000120024

Refer to the following data table, the above configuration parameters to set the wireless module is:

Network ID: 0000

RF transmit power: 12dbm

Serial speed: 9600bps

RF channel: 10

And check byte: 24

Return data: AA5B0521000000000004000A00000012004B

Set the node ID is invalid, set the number can be, does not affect the module's real ID, but the last byte and verify to be correct.

The return parameter will return the module ID. For example, the above module ID is: 0X0521

Operating instructions

After power-on, when the CS (Power-down) pin is connected to work low level, SET pin is to set the parameter flag, pulled low or shorted to the ground can die

The block is switched to the parameter configuration mode when the pin is set low, and the TXD and RXD pins operate at high level.

Serial port settings :

Once in the set state, the indicator light, SET pin configuration must be low, CS pin must be connected to low, and the serial port will be set

Must be data bit 8, baud rate 9600, parity bit N, stop bit 1, air rate 1Mbps.

Indicator light Description: The indicator light is steady when in the setting state, until it is off in the working state, the data received and the transmit data indicator light are on.

RF power setting:

Set the transmit power, [Parameter] 1 byte.

Setting range: 0-14 level

Serial port baud rate:

Set the serial interface transmission rate, [parameters] 1 byte

Setting range: 600 1200 2400 4800 9600 19200 38400
