Options Screen cont. – Section 30-B
Port and Protocol Options tab:
Select Port
Select the radio button for the COM Port to which you have connected the Interface. Serial
Ports should be assigned to COM1 through COM4 (most often COM1 by default) while
USB has only its eponymous choice. The NET setting is used by the HEX-NET interface
when it is operating in WiFi mode, see this page for more infornation:

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. This button turns into [Config]
when NET is selected for configuring a HEX-NET connected via USB.
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.
