The first part: hardware connection
1. RS485 communication connection
The controller device uses the RJ45 interface (RS485 communication protocol) to communicate with the
host computer:
Figure 1-1 RJ45 interface (RS485 communication protocol)
2.Connection between the device and the PC
Use the special network cable (1.5 meters) in our accessories to communicate with the RJ45 to USB
interface converter (RS485 communication protocol) to realize communication between the controller
and the host computer. See the wiring diagram below for details:
Figure 1-2 RJ45 to USB interface converter (RS485 communication protocol)
Figure 1-3 Device and PC connection diagram
Note: the special network cable crystal head blue sheath termination controller device, black sheath
termination RJ45 to USB converter, RJ45 to USB converter USB port and computer USB port plug-in
connection;
Warning：
It is forbidden to use any network cable as the communication cable to connect the device directly to the
PC monitoring port. Otherwise, the device and PC will be damaged!

In this interface, you can also change the parameters such as “Battery Type”, “Number of Battery
Strings” and “Work Mode” through the pull-down menu; the battery is powered by the lead-acid battery
by default; the working mode defaults to the household mode;
Click the “Restore Factory” button, the system's operating parameters will be restored to the factory
settings.
Note: Please don't modify the device ID address arbitrarily. Otherwise, the communication will be
abnormal. Generally, after the first configuration, you do not need to modify it again. Also, the “Restore
Factory” button should not be clicked because the factory settings are restored. At the same time, the
accumulated parameters such as charging and discharging power will be cleared, please be cautious;
3.4 Query function:
The system monitoring software can query the historical data of the controller. Click the “Query”
button in the menu bar to pop up the “History” submenu, click on the submenu to open the historical data
dialog box, as shown below figure 2-7.

As shown in the figure, in the dialog box, historical data can be queried, exported, deleted, and the
like.
Query phase data: first set the start time and end time (the start time needs to be less than the end
time), and then click “Query time period record” to query the running data of the time period;
Query all records: Click "Query all data" to query all running data;
Import, export, and delete historical data: Click the corresponding button to import, export, and
delete historical records. The exported data format is excel format, so the format of the data table when
importing is also the format of excel.
Note: The amount of data in the history record will be relatively large, so there will be a delay when
the query is created. Please wait patiently. The waiting time depends on the running speed of the
computer. Please be cautious when deleting data. Delete the data. It cannot be recovered. Please export
the data before deleting to avoid data loss, which will bring you unnecessary trouble.
