HEX-CAN-USB(512)
information
1. USB connector plugs into most modern laptops! (USB 1.1 or 2.0)
2. Compatible with the latest cars which require a direct CAN connection for diagnostics including all Golf-5 platform cars and latest Audi A3, A6 and A8.
3. Protocol timing indistinguishable from a real VAG/VAS tool. Works reliably even with "difficult" control modules such as the 1991-1994 1Z Audi TDIs and the 1993-1994 Audi 2.6L with Hella ECU.
4. Instantly alerts the user if either the K/K1 line or the L/K2 line is shorted to Ground or Vbatt.
5. Full support for dual-K lines found in "new" (B6/8E chassis Audi A4 and 2002+ Audi A6.
6. Fully backwards compatible with older cars using a single K-line or K plus L.

What is CAN and why is it important?
CAN stands for Controller Area Network. CAN is a new means of communicating with the car for diagnostics used by the latest generations of VW, Audi, SEAT, and Skoda vehicles. Unlike the older ISO9141 system, which used a single K-line for diagnostic communications, the new CAN-Bus system uses a twisted pair of wires with differential signaling. CAN is considerably faster than ISO-9141 (500 kpbs vs. 10.4 kbps). Both new hardware and new software are required in order to communicate with cars using CAN for diagnostics.
