This command means to send a code to a module, set the module address as 01, this setting could be saved when power off;
default address of module is 01,each module address could be assigned separately when using multiple modules for
network.Attentions is required that only one module could be used in 485 network when using multiple address sending,
otherwise all the modules will share the same address in 485 network. When module receives correct command, it will make
corresponding actions and send response back to the master. This is successful communication.

1814 2 CRC check code CRC check code for all data
Receive ： 01 06 00 65 00 02 18 14 （ example/hexadecimal ）
This command means to send a code to the module and set the communication parameter as “9600, N No check), 8, 1”.This
setting could be saved when power off. The default communication parameter is “9600, N no check), 8, 1”. Attention is
required, when electing the correct communication parameter in communication setting and restarting the communication
terminal, setting will be done.Normally, the lower of baud rate, the lower of the transaction speed but the higher of transaction
stability. The opposite is also true.When module receives correct command, corresponding action will be taken and response
will be sent back to the master. This is successful communication.
6 、 Indicator LED description
 When module powered on, Led is green.
 When module is under communication, LED is twinkling.
 when module receive correct command, LED is green.
 when module receive incorrect command or command for other modules, LED is red.
7 、 PC debugging instruction
This module provides software for parameter setting and function test. Please follow the steps below:
 Connect the module and computer using RS485 converter.
 Connect 12V or 24V power with module and power on. To avoid any unnecessary damage, please make sure the power
positive & negative terminals are correctly connected before power on.
 Open the software, select the correct module number, you will see the window of function test or parameter setting.
 Set correct parameter, open communication interface.
 Select corresponding setting, collection and control items.
