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 protcols.
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. If you need more distance 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
