High Speed
ISOBUS
A next-generation high-bandwidth network designed to move agricultural machines beyond the limits of the traditional CAN-based ISOBUS backbone.
01 / Overview
Why a new network?
Classic ISOBUS has enabled cross-manufacturer communication for tractors and implements, but its CAN-based physical layer operates at 250 Kbit/s. AEF describes increasingly complex agricultural systems as capable of consuming much of that available bus capacity, increasing latency and constraining new uses.
High Speed ISOBUS is being developed to add a much higher-performance network while classic ISOBUS continues to serve established functions. The HSI work covers architecture, hardware interfaces, cabling, connectors, and protocols for initial use cases such as command and control and digital camera systems.
02 / Comparison
Two networks,
different roles.
The figures below reflect AEF public descriptions. They explain nominal communication capacity, not complete system performance.

From sensing
to action.
This conceptual path shows how HSI can connect high-data-rate components. It is an educational abstraction, not a certified implementation topology.
