powered wiring method
If the voltage range of the tested battery is between 10-120V during normal
operation,self-powered wiring can be used. First, turn the power supply
selection interface switch to “2W”, and then connect the positive terminal of
the battery to the power supply interface “Vsns” , This line does not need to
be particularly thick,13-16AWG wire is fine. Pay attention to the positive and
negative poles of the battery, do not connect the wrong or reverse connection.
The negative pole of the battery is connected to the screw with the battery
GND on the sampler, and the negative pole of the charger and the negative pole
of the load are connected to another screw of the sampler. It is better to use
a copper nose to connect it firmly. When charging, the current direction
symbol color is red, and the remaining capacity value increases. When
discharging, the color of the current direction symbol is sky blue, and the
remaining capacity value decreases.

3.Communication protocol control
We only provide communication protocol, customers can carry out secondary
development according to communication protocol. 1.Overview
The command line is used as the control command, and the
22
Hangzhou Junce Instruments Co., Ltd.
communication rate is 115200. The PC sends out the command, the meter parses
and executes it, and then returns the result to the PC. The different commands
are described below. The sending data format is as follows
Start bit
Checksums 1-255
Function code W,R
Spacer ,
Function No. 00~99
Data field See instructions
Connector =
Spacer ,
Address symbol 1-99
Terminator
Spacer ,
Explain: (1) Function code: “W” is the write instruction used to set various
parameters, and “R” is the parameter used by the read instruction to return to
the machine. (2) Function No.: different values represent different parameter
settings. (3) Address symbol: address range is 1-99, 0 is broadcast address.
(4) Checksum: the value of the sum is obtained by adding 1 to the remainder of
255 after the sum of all the numbers after the check sum. If the sum of the
check is taken as 0, it means that it is not verified. (5) Data field: the
data field is equivalent to the number of operations of the command. For
example: W20=12162000, the instruction operands are 2000, which means that the
over voltage protection is set to 20.00V. (6) Terminator: Each instruction
ends with a carriage return + line feed, and
