Version 2.x
Version 2.x works only with special proprietary hardware.
There are two version of interface: SmartVAG (Serial) and BlueVAG (Bluetooth).
SmartVAG and BlueVAG contains embedded firmware that implements high reliable proprietary
protocol and guarantee very fast and stable ECUs connection, they also works as dongle for VAG-Check 2.0 activation. Interfaces are user firmware
upgradable to guarantee your investment for the future.
You can buy your 2.x compatible interface here. VAG-Check 2.0 is NOT compatible with old Optocoupler/MAX232 based interface!

Board image(bottom side) to use for the production of the master to etch your board. The image is in true size and could be printed with the following settings W 28.61mm H 33.08mm
|
Here the obtained result! Wires are directly weld to the circuit.
IMPORTANT!
|
If you connect your Jeff's interface (or that described here) with normal serial PDA<->PC syncro cable, you MUST insert a Null Modem adapter between two cables, otherwise you couldnt establish any unit communication!
Since version 1.1.1 VAG-Check supports Socket Serial CF adapter that doesn't need null-modem!
|
Null Modem adapters are not all the same!
Table below shows serial 9 pins Null Modem pinouts that works.
