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
