- Program Options

On this screen you can set a number of Options.

Select Com Port

Set the COM Port to which you have connected the Interface Adapter.  
You can then click [Test] to see if VCDS-Lite can find the adapter.

Other

  • Debug Level controls how much debugging information VCDS-Lite records. A zero in this field (the default) means NO debug output will be generated whatsoever. This should decrease VCDS-Lite's susceptibility to interference by things like virus scanners (except when logging data). There should be no reason to set Debug to anything other than zero unless you are instructed to do so by Ross-Tech.
  • 256 Color Mode for old PC's This display mode changes the background color from blue to white, and looks better on some older monitors. The change will take effect after you close and restart VCDS-Lite.
  • Left Margin Printing This is the number of spaces that printed pages are shifted to the right.
  • Window Size This function allows you to change the apparent size of the VCDS-Lite window on your screen. To see the resizing take effect, click Save, then close VCDS-Lite. When you restart, the new window size should be shown. Adjust this in small increments since it is possible to make VCDS-Lite so large that it is much bigger than your screen! If that happens delete this file from your PC:
    C:\Ross-Tech\VCDS-Lite\VCDS.CFG
    You'll then need to Test and Save again.
  • Protocol Options

    • Start Baud is the first baud rate that VCDS-Lite will try when connecting to a controller. The current default value is 0. This means VCDS-Lite will determine the correct start baud on its own. With our current Interfaces, this field is unavailable.

    • KW2 Delay has to do with the amount of time used during the initialization of a session between the PC and the car. The current default value is 30. Do not change this value from the default unless you are having difficulties communicating with a particular controller. Contact us for advice if you are.

    • TST Addr. has to do with the packet addresses used by KWP-2000. The current default value is -1. Do not change this value from the default unless you are having difficulties communicating with a particular controller. Contact us for advice if you are.

    • Debug Level controls how much debugging information VCDS-Lite records. A zero in this field (the default) means NO debug output will be generated whatsoever. This should decrease VCDS-Lite's susceptibility to interference by things like virus scanners (except when logging data). There should be no reason to set Debug to anything other than zero unless you are instructed to do so by Ross-Tech.
    • Reduce CPU Usage checkboxes will greatly increase responsiveness of other apps running at the same time as VCDS-Lite. The disadvantage is somewhat reduced sample rate.

      • KWP-1281: The default value is unchecked. This reduces CPU usage when connected to controllers using KWP-1281. Using this feature *may* make the session with some control modules unreliable.

      • KWP-2000: The default value is unchecked. This reduces CPU usage when connected to controllers using KWP-2000

    • Blk Int affects the protocol timing. The current default value is 55. To get the highest sample rate possible in the Measuring Blocks screen, set this to 25. Note, however, that this may cause unreliable communications with some controllers.

    • Char lnt also affects the protocol timing. The current default value is 1. To get the highest sample rate possible in the Measuring Blocks screen, set this to 0. Note, however, that this may cause unreliable communications with some controllers.

    • KP2 Time only applies to controllers using the KWP-2000 protocol. The current default value is 25. Decreasing it increases the sample rate in Measuring Blocks on control modules that use the KWP-2000 protocols. The default value should be safe for all applications, but if it's not, you can always increase it again (to a maximum of 99).

    • Echo Delay

    The WorkShop Code (known as the WSC) is found on the Admin screen of a dealer's VAS-5051, as well as on the dealer's stamp. The default value is 00000. For example, using the stamp below, the dealer's number is 401/742. To derive the Work Shop Code, drop the first digit and use the remaining digits in order. If you are an individual user or independent mechanic, just leave the WorkShop Code set to "00000". This allows VCDS-Lite to operate in “stealth” mode, keeping whatever WSC that was already in the controller. If you are using VCDS-Lite at a Dealership, enter your Dealer's Workshop Code. The Work Shop Code is not easily changed once set on this screen. Contact us for advice if you need to do so.

    The VZ/Importer number is essentially a "region code" extension to the Work Shop Code (should be 444 for US, 999 for Canada). The default value is 000.

    If you are an individual
    user or independent mechanic, just leave the VZ/Importer number set to "000". This allows VCDS-Lite to operate in “stealth” mode, keeping Importer number that was already in the controller. If you are using VCDS-Lite at a Dealership, enter your Dealer's VZ/Importer number. The VZ/Importer number is not easily changed once set on this screen. Contact us for advice if you need to do so.


    Shareware Limitation(s):
