An Isobus object pool is a central element of the ISO 11783-6 standard. It defines the graphical user interface (GUI) that is displayed on a Virtual Terminal (VT) when an Isobus-compatible implement or machine component is connected. The object pool contains a structured collection of graphical objects such as texts, images, buttons, lines, and more complex elements like bar charts. These objects are stored as a binary file (usually with the extension .iop) and transmitted from the implement to the VT, providing a standardized and cross-manufacturer operating interface.
