The Ross-Tech VCDS system, utilizing the HEX USB CAN interface, is a powerful diagnostic tool for Volkswagen, Audi, Seat, and Skoda vehicles. This article clarifies the distinctions between different generations of Ross-Tech interfaces, specifically focusing on the HEX+CAN and the newer HEX-V2, often searched for as “Vcds Ross Tech Hex Usb Can.” Both utilize the CAN protocol for communication but have key differences in functionality and future compatibility.
HEX+CAN vs. HEX-V2: Key Differences
The core difference between the HEX+CAN and HEX-V2 lies in their ability to communicate with newer vehicle models. The HEX+CAN faces limitations with 2016 and later models due to evolving communication protocols within these vehicles. The HEX-V2, built on the foundation of the HEX-NET, overcomes this limitation by incorporating a more advanced 32-bit microcontroller, enabling seamless diagnostics on newer cars.
For vehicles relying on the older K-Line protocol, both interfaces perform similarly as the communication speed bottleneck lies with the vehicle’s module, not the interface. However, the significant speed improvement offered by the HEX-V2 on CAN-based cars makes it the preferred choice for current and future vehicle diagnostics.
Future Support and Legacy Software
Ross-Tech has indicated that older generation interfaces, including the HEX+CAN, will eventually reach their end-of-life for software updates. While a legacy version of VCDS software will likely remain available for continued use with these older interfaces, users will need to upgrade to newer hardware, like the HEX-V2, to access the latest features and support for the newest vehicle models. This transition is not imminent, with a timeline estimated to be at least a year or more away.
HEX-V2 vs. HEX-NET: WiFi and Onboard Storage
The HEX-V2 shares its core technology with the HEX-NET, utilizing the same powerful microcontroller. However, the HEX-NET distinguishes itself with integrated WiFi capability and local onboard storage. This functionality powers VCDS-Mobile, allowing users to perform diagnostics using a wide range of devices with WiFi and a web browser, including smartphones, tablets, and laptops. The HEX-V2 is a USB-based interface, providing a direct connection to the diagnostic port.
Choosing the Right Interface
For users primarily working with older vehicles (pre-2016), the HEX+CAN may still suffice. However, for those requiring compatibility with newer models and seeking future-proof diagnostics, the “vcds ross tech hex usb can” search often leads to the HEX-V2, which offers a clear upgrade path. The HEX-NET provides additional flexibility with its wireless capabilities and mobile device compatibility.
