Issue:

Downloaded Log files from the SAGE RTU Graphic User Interface (GUI) appear in unreadable characters (e.g., Chinese symbols) when opened in standard text editors like Notepad.

Product:

Sage RTU Series (SAGE 1X10, 1X30, 1X50, 2X00, 3030X)

Environment:

• SAGE RTU GUI
• Windows OS (using default Notepad)
• Log files downloaded from RTU

Cause:

The issue occurs because the files use UTF-8 encoding, and standard Notepad does not properly interpret this encoding by default, resulting in unreadable characters.

Resolution:

1. Use a text editor that supports UTF-8 encoding, such as Notepad++ (recommended).
2. If the file still shows NULL or strange symbols:
• In Notepad++, go to Encoding → Convert to UTF-8.
• Save and reopen the file; it should display correctly now.
3. Alternative applications:
• WordPad
• Spreadsheet viewers (e.g., Excel)
4. Ensure the file is not corrupted before conversion.

Example, Using Notepad:

Using NotePad++:
