T is command means to send a code to t e module and set t e communication parameter as “9600, N (No c eck), 8, 1”.T is
setting could be saved w en power off. T e default communication parameter is “9600, N (no c eck), 8, 1”. Attention is
required, w en electing t e correct communication parameter in communication setting and restarting t e communication
terminal, setting will be done.Normally, t e lower of baud rate, t e lower of t e transaction speed but t e ig er of transaction
stability. T e opposite is also true.W en module receives correct command, corresponding action will be taken and response
will be sent back to t e master. T is is successful communication.
6 、 Indicator LED description
 W en module powered on, Led is green.
 W en module is under communication, LED is twinkling.
 w en module receive correct command, LED is green.
 w en module receive incorrect command or command for ot er modules, LED is red.
7 、 PC debugging instruction
T is module provides software for parameter setting and function test. Please follow t e steps below:
 Connect t e module and computer using RS485 converter.
 Connect 12V or 24V power wit module and power on. To avoid any unnecessary damage, please make sure t e power
positive & negative terminals are correctly connected before power on.
 Open t e software, select t e correct module number, you will see t e window of function test or parameter setting.
 Set correct parameter, open communication interface.
 Select corresponding setting, collection and control items.
