Wiring methods

Wiring instructions video：http://68.168.132.244/KL-F_jxfs_EN.mp4

1. Self-powered wiring method If the voltage range of the battery under test is between 10-120V during normal operation, self-powered wiring can be used. First, turn the power selection interface switch to “2W”. When wiring, connect the positive terminal of the battery to the power interface “VSNS”. This line does not need to be particularly thick. The 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 “BATT-” printed 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 of the APP 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.
2. External power supply wiring method The measuring voltage range of the external power supply is 0-120V. First, set the power selection interface switch to “3W”, connect the positive pole of the external power supply to the power interface “VEXT”, and connect the negative pole of the external power supply to “GND”. When wiring, connect the positive pole of the battery to the measurement interface “VSNS” in the power interface. Note that the positive and negative poles of the battery and the external power supply should not be connected incorrectly or reversed. The negative pole of the battery is connected to the screw printed “BATT-” on the Shunt, and the negative pole of the charger and the negative pole of the load are connected to the other screw of the Shunt together. It is better to use a copper nose to connect firmly. When charging, the current color on the mobile phone APP is green, and the remaining capacity value increases. When discharging, the current color is sky blue, and the remaining capacity value decreases.
3. External power supply wiring method (Relay control) The working power of the relay is provided by an external power supply. If the relay is connected, an external power supply with the same working voltage as the relay should be provided. Connect the control ports of the relay to the “OUT” and “VEXT” of the measurement module Output Control, connect the positive pole of the external power supply to the “VEXT” of the Output Control, and the negative pole of the external power supply to the “GND”. Note that the positive and negative poles of the battery and the external power supply should not be connected wrongly or reversed. If you want to control the charging or discharging, you should connect the wiring according to the wiring diagram of the external power supply relay in Figure 3-2-3. When the relay is closed, the indicator light will be on, and when it is disconnected, it will be off as a prompt. The negative pole of the battery is connected to the screw printed “BATT-” on the Shunt. The negative pole of the charger and the negative pole of the load are connected to the other screw of the sampler. It is better to use a copper nose to connect it firmly. When charging, the current color on the mobile phone APP is green, and the remaining capacity value increases. When discharging, the current color is sky blue, and the remaining capacity value decreases. （The external power supply voltage is subject to the working voltage of the relay; for example, 12V or 24V.）

Communication protocol control

We only provide communication protocol, customers can carry out secondary development according to communication protocol.

Summary
The command line is used as the control command, and the 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| Function code| Function No.| Connector| Address symbol| Spacer
---|---|---|---|---|---
：| W, R| 00~99| =| 1- 99| ,
Checksums| Spacer| Data field| Spacer| Terminator|
1- 255| ,| See instructions| ,| < CR>|

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 the 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 checksum. 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 represents the carriage return in the ASCII character table (hexadecimal representation is 0x0d). is the newline character in the ASCII character table (in hexadecimal notation is 0x0a). The above two methods indicate carriage return and line feed.
