Protocol 7.00 Screenstreaming – fx-9860G and fx-CG screenstreaming

Screenstreaming, also named “OverHead Projector” (OHP), “Projector”, or “Screen Receiver”[1], is a mode in which the calculator shares its screen contents to another device.

This protocol is analogous to Protocol 7.00, see Protocol 7.00 – Serial and USB protocol used by post fx-9860G calculators for more information. It is used on the same models and during the same period of time.

However, it has its own packet formats and flows that make it effectively a completely separate protocol, sharing only a few similarities. Therefore, it is documented in a completely separated set of sections and documents from the original protocol, for clarity.

Screen Receiver is the name of the piece of software by CASIO to view the calculator’s screen from a desktop PC running on MacOS, OS X or Microsoft Windows.
