6. What are the Computer and Wi-Fi Requirements for VCDS with HEX-NET?

To ensure optimal performance with VCDS with HEX-NET, the following computer and Wi-Fi requirements should be met:

Computer Requirements:

• Processor: Minimum 1 GHz dual-core processor.
• RAM: At least 1 GB of RAM.
• Operating System: Windows 7 or newer is recommended. Windows 8, 8.1, and 10 are also suitable if the machine is robust enough to support them. Older operating systems like Windows 2000, XP, and Vista may work but are not officially supported.

Wi-Fi Requirements:

• Frequency: 802.11 b/g at 2.4 GHz.
• Access Point Mode: The client device (laptop, tablet, etc.) must support 802.11 b/g at 2.4 GHz.
• Infrastructure Mode: Both the client device and the router connected to the Internet need to support 802.11 b/g at 2.4 GHz.
• Unsupported: 5 GHz Wi-Fi and channels 12 and 13 are not supported.

7. How Do I Extend the Reach of My VCDS with HEX-NET Interface?

To extend the reach of your VCDS with HEX-NET interface, consider the following:

• OBD Extension Cable: Use a 3-foot OBD extension cable. This allows you to keep the diagnostic tool connected without it being in the way.

8. How Does VCDS with HEX-NET Handle Registration and Resale?

Registration:

• Interfaces purchased directly from Ross-Tech are typically pre-registered.
• Interfaces bought from authorized resellers must be registered online within 10-15 uses using a utility provided with VCDS.

Resale:

• The HEX-NET interface acts as a “dongle” for VCDS, so the software should function fully on any PC used with the interface.
• Product support is provided only to the original registered user. If you purchase a second-hand HEX-NET, you may need to pay a fee to re-register the interface in your name to receive support.

9. What Software is Compatible with VCDS with HEX-NET?

The HEX-NET interface is primarily designed for use with the latest version of the VCDS software. It does not emulate a dumb serial pass-through interface, making it unlikely to be compatible with other diagnostic software. Using the latest VCDS version ensures optimal functionality and access to the newest features and updates.
