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 VAG-COM can find the adapter.

For the HEX-COM+CAN and HEX-USB+CAN Interfaces, then K1, K2, and CAN should all say OK as shown above. For the Micro-CAN Interfaces, K1 and K2 should show "Not Supported" while CAN should say OK. For the KEY-COM and KEY-USB as well as with the older HEX-COM and HEX-USB, K1 and K2 should both be OK while CAN should say "Not Supported".

The [LED�s] button is useful for testing a port's outputs with the Interfaces that have LED's.

User Interface

• 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 VAG-COM.

• 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 VAG-COM window on your screen. Adjust this in small increments since it is possible to make VAG-COM so large that it is much bigger than your screen! To see the resizing take effect, click Save, then close VAG-COM. When you restart, the new window size should be shown.

Protocol Options

• Start Baud is the first baud rate that VAG-COM will try when connecting to a controller. The current default value is 0. This means VAG-COM 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 VAG-COM records. A zero in this field (the default) means NO debug output will be generated whatsoever. This should decrease VAG-COM'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.

• 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).

• CAN Timeout defines how much longer than normal VAG-Com is going to wait for the module to respond to a given message. Do not change this value from the default value of zero unless you are having difficulties communicating with a particular controller. Contact us for advice if you are.

Init Parameters

• Bypass OBD-II Fastinit should only be checked if you are experiencing difficulty connecting to a vehicle using generic OBD-II.

• Force K on Engine is used on controllers that use the CAN-Bus for diagnostics. This feature can be useful since the K-line often delivers faster sample rates while datalogging than does the CAN-Bus on modules that support both. Since some modules talk only via CAN, this box is unchecked by default.

• Bypass CAN Init should only be checked if you do not want VAG-COM to try connecting to vehicles using the CAN-Bus.

• Force Dumb Mode is used to prevent VAG-COM from automatically determining the baud rate for connections..

Reduce CPU Usage checkboxes will greatly increase responsiveness of other apps running at the same time as VAG-COM. 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

[Restore Defaults] will reset all Protocol Options (except WorkShop Code and VZ/Importer number) to their "as-delivered" settings.

Workshop Identification

• Shop Name is displayed on reports, such as the Fault Code Report.

• 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.

   

So, Evergreen Terrace Volkswagen has a WSC of 01742. This only applies to US VW dealers. Canadian dealerships use a 4-digit number on their stamp. To find the WSC, place a 9 before their number.

Note: If you are an individual user or independent mechanic, just leave the WorkShop Code set to "00000". This allows VAG-COM to operate in �stealth� mode, keeping whatever WSC that was already in the controller. If you are using VAG-COM 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.
  
  Note: If you are an individual user or independent mechanic, just leave the VZ/Importer number set to "000". This allows VAG-COM to operate in �stealth� mode, keeping Importer number that was already in the controller. If you are using VAG-COM 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.
   
• The Equipment Number field is used most often when coding new control modules. Some control modules will refuse being recoded if they're not given an equipment number (sometimes they require a non-zero WSC and Importer number too). In those cases, any numbers should work. The default value is 00000.

[Save] causes the current options to be stored. Note that until you have Saved your preferences, all buttons on the VAG-COM Main Screen will be grayed-out except Options.

[Apply] lets you use and test the options without storing them.

[Cancel] takes you back to the Main Screen without any effect.

Shareware Limitation(s):  None.
