- PC connectivity with VCDS via WiFi or USB
- Includes VCDS-Mobile
bringing VW/Audi diagnostics to devices such as smartphones and tablets. A chart showing the currently supported functions can be found here.
- Compatible with all
diagnostic-capable VW/Audi passenger cars from 1996 to
current; K, K+L, dual-K, or CAN.
- Detachable USB cable. The supplied cable
has a proprietary screw locking mechanism, but it can be replaced temporarily with
a standard USB-A to USB-B ("printer") cable should it become damaged.
- Modern 32-bit
micro-controller and fully updateable firmware.
- Three bi-color (red/green) status/activity LEDs
- 12 month guarantee against
defects in workmanship or materials.
- Includes an embedded license
for VCDS and thus acts as a "dongle" for the software,

This interface terminates in an
OBD-II type connector that plugs right in to most 1995 and
newer VW's and 1996 and newer Audis. It is also
compatible with many 1990-1995 Audis and 1990-1994 VW's have
"2x2" data link connector, click here for more info.
This interface works with all
diagnostic-capable VW-Audi Group passenger cars from 1990
through current, except it does NOT fully
support the following vehicles:
Routan vans -- All years.
These are re-badged Chryslers and don't use VW's diagnostic protocols.
Some 1991-1994 Audi TDI engines with ECUs
that communicate at 240bps.
We recommend at least a 1 GHz
dual-core processor with 1 GB of RAM and Windows 7 or newer.
Slower computers or Windows 2000, XP, and Vista may work but
are not officially supported. Windows 8. 8.1, or
10 on a machine robust enough to support the respective
operating system are also fine.
To use the HEX-NET wirelessly, it needs to communicate via 802.11 b/g at 2.4 GHz.
This means that for Access Point mode, the client device with the web browser (laptop computer, tablet, etc.) needs to support 802.11 b/g at 2.4 GHz.
To use the HEX-NET in Infrastructure mode, both the client device and the router that is connected to the Internet need to support 802.11 b/g at 2.4 GHz.
Specifically, 5 GHz WiFi is not supported nor are channels 12 and 13 supported.
Extending this Interface:
The cable supplied with this
interface is about 6 feet long -- just right for most
laptops. We sell a 3-ft OBD extension in our web store that lets you keep your diagnostic tool connected and away from the driver's feet and legs. If you need more than that ... well, it's a WiFi interface! ;-)
In most cases, interfaces
purchased directly from Ross-Tech will be pre-registered.
Interfaces purchased from our authorized resellers must be
registered within 10-15 uses to remain functional.
Registration is accomplished on-line using a utility
supplied with VCDS.
This interface acts as a
"dongle" for VCDS, so the software should be fully
functional on any PC you use with the HEX-V2. However,
product support is provided only to the original registered
user. If you buy a second-hand HEX-USB+CAN from
someone and want support, you'll still need to pay $99 to
re-register the interface in your name..
The HEX-NET should be used
with the latest
version of our VCDS software.
The HEX-NET does not have the ability to emulate a
dumb serial pass-through interface and thus unlikely to be
compatible with any software other than VCDS.
The HEX-NET enumerates as an HID device and does not
require a special driver. However, there are some HID
power management quirks in 8.1 and newer fixed by
installing a device-specific "driver" (actually just an INF
file) supplied with the VCDS installer.
When used with VCDS on a PC via WiFi, Windows Firewall may ask
you to allow traffic from VCDS. If this happens, you should allow it.
There is also an "Open Windows Firewall for HEX-NET via WiFi" option
in the VCDS-Installer that can and should be selected to pre-allow the
