VCDS Release 11.11 PDF Manual Printing Instructions: - Ross-Tech

Port and Protocol Options
Select Port
Options Screen cont. – Section 30-B
Set the COM Port to which you have connected the Interface Adapter. Serial Ports should
be assigned to COM1 through COM4 (most often COM1 by default) while USB has only its
eponymous choice. Make sure the ignition is turned on and the interface plugged into the
vehicle, then click [Test] to see if VCDS can find the interface. See Getting Started (section
1 in this manual) for more information.
The [LEDs] button causes the LED on the Interface to blink and may be useful for testing a
port's outputs for troubleshooting certain connection issues.
Protocol Options
Start Baud is the first baud rate that VCDS will try when connecting to a
controller. The current default value is 0. This means VCDS 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 records. A zero in
this field (the default) means NO debug output will be generated whatsoever.
This should decrease VCDS'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.
