Receive: 01 06 00 00 2C 39 55 18 （example/hex）
This command sets module to output current.
The data of the analog output is “2C39”, it will be 11321 after converting to decimal data. Put it in the formula:
Iout=DATA/1000=11321/1000=11.321mA.
When module receives correct command, it will send response back to the master.

This command reads module’s current output data.
The data of the analog output is “2C39”, it will be 11321 after converting to decimal data. Put it in the formula:
Iout=DATA/1000=11321/1000=11.321mA.

This command sets module address (slave address) as “01”(default setting). This setting could be saved when power off.
This is a broadcast command. It needs to ensure that only one module is connected to the master.
When module receives correct command, it will send response back to the master.

This command sets communication parameter as “9600, None, 8, 1” (default setting). This setting could be saved when
power off.
When module receives correct command, it will send response back to the master.
6、POWER/DATA LED description
⚫When module powered on, LED is green.
⚫When module is under communication, LED is twinkling.
⚫When module receives correct command, LED is green.
⚫When module receives incorrect command or other module’s command, LED is red.
7、PC debugging description
We provide a debugging software for function testing and parameter setting. Please follow the steps below:
⚫Connect computer to module with RS485 converter.
⚫Connect DC12V or DC24V power to module and power on. To avoid any unnecessary damage, please make sure the
power positive and negative terminals are correctly connected before power on.
⚫Open the software and select the model of module, you will see the window of function testing or parameter setting.
⚫Set communication parameter and open the serial port.
⚫Select corresponding setting and click “Read”or “Write”button.
