This adapter comes with an OBD-II type connector which plugs right in to most 1994 and newer VW's and 1996 and newer Audis.   Most 1990-1995 Audis and 1990-1993 VW's have the "2x2" data link connector, click here for more info.

Extending this Interface:

The cables on this interface have a total length of about 6 feet  -- just right for most laptops.   If you want to use this interface with a desktop PC, you should get an RJ45 Coupler (available as a $5 option on our order form) and an ordinary CAT5 Ethernet Patch Cord in whatever length you need up to 100' (30m).   Make sure the Patch Cord has all 8 conductors and is wired "Straight Through".   A "Cross-Over" type cable is not acceptable and may damage your interface.   See the this FAQ entry.   Always extend the car-side of this interface.  We do not recommend or support extending the PC side of this interface.

Known Issues:

Some Acer and Compaq Presario Laptops  have "lame" serial ports which do not come close to meeting the RS-232 spec and will not work properly with this adapter.   If you have an Acer or Presario,  you should use a TWIN-COM, TWIN-USB and HEX-COM .

A few models of cars have extremely tight trim around the OBD-II connector.  The ISO-COM uses an OBD-II connector that is sometimes difficult to fit easily into the following cars:  

•  Audi A4 Models with diagnostic connector next to rear ashtray.   US: 1996 only.   Rest of World: 1995-2001 (all 8D chassis).    US models from 1997 through 2002 are fine.
• Audi A6 models with diagnostic connector in center-console between seats.    US:  1996-1997 (sedan) and 1996-1998 (Avant).    Rest Of World:  Likely the same. 
• VW Passat 3B Chassis with diagnostic connector in center-console between seats (1997-2002)   Non-US models only!  US models have diagnostic connector under dash and work fine.

Note:

We do not sell any interface adapters  as a "Stand-Alone" products.   We only sell them with our software.
