NORITAKE ITRON VFD MODULES GU126x64F-K612A4 is a high brightness dot graphic VFD module produced by NORITAKE ITRON, which has a single 5V DC supply, 3 ASCII fonts, SPI and RS232 asynchronous serial interface, 8 user I/O pins and other features.
This manual describes the electrical and optical specifications of the Noritake GU126x64F-K612A4 dot‑matrix VFD module, including power supply requirements, voltage levels for RS232 and logic I/O, display dimensions, luminance, and environmental limits. It also lists the available fonts, I/O pins, and key‑scanning capabilities.
The document contains a complete command set for both asynchronous (RS232/TTL) and synchronous serial interfaces, instructions for displaying text and graphics, area‑fill and outline commands, checksum handling, and macro programming for custom screens and power‑up messages.
