Files with the file extension BIN are for the basic unit of the UL3000/6000

Files with the file extension INFICON are for the operating unit of the UL3000/6000

The ARCHIVE folder contains older series versions for basic unit and operating unit for the UL3000/6000

Files with the sha256 extension contain the hash values of the corresponding files.
They are not needed for the upgrade process.

You can use them to verify the integrity of the downloaded file.

To do this, you need a tool that supports the SHA-256 algorithm.
The verification compares the hash value of the file to the value stored in the .sha256 file.

Verification steps:
Download the file and the corresponding .sha256 file.

Use a hash calculation tool, such as
On Linux/macOS: the built-in sha256sum command
On Windows: Tools such as CertUtil or external programs such as HashCheck

Example for Linux:
    sha256sum -c filename.sha256

Example for Windows:
    certutil -hashfile filename SHA256
Open the .sha256 file with any text editor and manually compare the hash output with the file content.
