YuanJi Data Calculator Software License –M02

YuanJi Hex File Verification Software License – M02 Menu

Product Overview

This product is a digital activation license for the M02 menu of YuanJi Hex File Verification Software. The M02 menu is designed for hexadecimal file checksum verification, XOR calculation, LRC calculation, BCC calculation, SUM checksum calculation, selected data range checking, and technical data consistency review.

The software is used to help technicians check whether the calculated verification value of a hexadecimal or binary data file is correct according to supported calculation rules. It includes YuanJi built-in custom verification rules for technical file checking, data consistency review, and calculation result comparison.

This product is a digital software license only. No physical product will be shipped.

Main Purpose

The M02 menu is mainly used for checksum and verification value calculation of hexadecimal files. Users can load an authorized binary, EEPROM, MCU, or technical data file, select a defined data range, and use the software to calculate and compare verification values.

The software helps users review file integrity, compare calculation results, check verification values, and confirm whether selected data sections match the expected checksum logic.

Main Software Functions

1. Hexadecimal File Verification

   The M02 menu allows users to load hexadecimal or binary files and verify selected data sections. It is designed for technical file checking, data consistency review, and calculation result comparison.

2. XOR Checksum Calculation

   The software supports XOR checksum calculation for selected data ranges. This function helps users calculate XOR verification values and compare the result with the expected value for technical verification purposes.

3. LRC Checksum Calculation

   The M02 menu supports LRC checksum reference calculation. Users can calculate LRC values for selected data sections and use the result for data consistency checking and technical file verification.

4. BCC Checksum Calculation

   The software supports BCC checksum calculation and verification. This function is used to check selected hexadecimal data ranges and compare the calculated BCC result with the expected value.

5. SUM Checksum Calculation

   The M02 menu supports common SUM checksum reference calculations for selected data areas. Supported calculation types may include selected variants such as SUM8, SUM16, SUM32, byte sum, word sum, and additive checksum reference.

6. Built-in Custom Verification Rules

   The M02 menu includes YuanJi built-in custom verification rules. These rules are used only for calculation reference, file verification, checksum comparison, and technical data consistency checking. They are not remote operation services and do not provide unauthorized data modification services.

7. Selected Data Range Checking

   Users can select a specific address range, file section, data block, or technical area for calculation instead of processing the entire file. This helps improve efficiency when only a defined section of a file needs to be reviewed.

8. Technical Data Review

   The M02 menu can assist with hexadecimal data inspection, verification value checking, calculation result comparison, and file structure review during authorized repair, testing, development, or educational workflows.

Supported Verification Types

The M02 menu may support selected verification and checksum calculation types such as:

• XOR Checksum

• LRC Checksum

• BCC Checksum

• SUM8 Checksum

• SUM16 Checksum

• SUM32 Checksum

• Byte Sum

• Word Sum

• Additive Checksum

• Modulo Checksum

• One’s Complement Checksum

• Two’s Complement Checksum

• YuanJi built-in custom verification rules

The available calculation types may depend on the software version and activated menu options.
