TXT Viewer

Directly view TXT files on your IODD screen. Ideal for checking serial keys or installation notes during work.

The TXT Viewer is a highly convenient tool that allows you to read text files directly on the IODD's built-in display without needing to connect to a operating system.

Supported Formats

To ensure proper rendering of text on the small display, please check the encoding of your files:

• Supported Encodings: UTF-16 (UCS-2) and ASCII.

• Incompatibility: Certain Asian character codes and complex encodings may not be supported.

[!TIP] Encoding Tip If a text file appears garbled or shows broken characters, try re-saving the file on your PC using UTF-16 Little Endian encoding for the best compatibility.
