Communications Interfaces

Ross-Tech can supply two different Interfaces (the hardware needed to connect a PC to your car).

Both of our current interfaces are universal on the car-side, supporting all VW/Audi Group passenger cars from 1996 to current, including k-line and CAN-Bus diagnostics. Both will also work with many 1990-1995 (OBD-I) cars, but these may require the optional "2x2"cabling adapter.

Both interfaces can be plugged into any standard USB port on a PC. However the HEX-NET can also be used with VCDS wirelessly via WiFi, and it gives you access to VCDS-Mobile, while the HEX-V2 is strictly for use with VCDS on a Windows PC via USB.

This generation of interfaces is much faster on modern, CAN-based cars than any of our now discontinued legacy interfaces.

VCDS also works with many 1990-1995 (pre OBD-I) cars, but these may require the optional "2x2"cabling adapter. This 2x2 adapter works with any of the above Interfaces. The 2x2 adapter is shown to the left and a 2x2 port in a car is shown to the right.
