Modern vehicle development programs continue to increase the volume of measurement data, CAN FD traffic, and integration complexity required during calibration and validation workflows. The VISION Network Hub 2 (VNH2) was developed to provide the throughput, CAN FD support, and rugged reliability needed for these evolving applications.
Serving as the central communication gateway between ATI VISION software and ATI hardware platforms, the VNH2 enables synchronized communication with ATI EMX and EDAQ modules while also interfacing with generic CAN FD and Classic CAN networks.
Compared with the original VNH1, the VNH2 provides:
-
Higher communication throughput
-
Full CAN FD support
-
Improved support for larger acquisition systems
-
Enhanced power protection circuitry
-
Continued compatibility with existing VNH1 installations
The result is a modern CAN gateway platform that supports both current and future automotive development requirements without disrupting existing ATI workflows.
Why VNH2
Accelerate High-Channel-Count Data Acquisition
As vehicle systems continue to increase in complexity, engineers need higher bandwidth communication between software and instrumentation hardware. The VNH2 increases throughput compared with the original VNH1, helping teams support larger acquisition systems and faster measurement rates.
Simplify CAN FD Integration
With support for CAN FD and Classic CAN across all four channels, the VNH2 allows development teams to work with modern vehicle networks and legacy systems simultaneously.
Optimize ATI Hardware Workflows
The VNH2 is specifically designed to integrate with ATI EMX and EDAQ measurement hardware and ATI VISION software environments. Dedicated instrumentation CAN FD channels help streamline configuration and communication with ATI systems.
Upgrade Existing Systems with Minimal Changes
Mechanical and cabling compatibility with VNH1 helps reduce migration effort for existing installations. Existing mounting strategies and cabling infrastructure can remain in place while upgrading to improved CAN FD performance.
Improve Reliability in Harsh Environments
Automotive and industrial validation environments require hardware designed for electrical and environmental stress. The VNH2 includes galvanic isolation, integrated termination switches, and auto-resetting current limiting circuitry to improve operational reliability.
