2.3 Interface
Kvaser USBcan Pro 2xHS v2 provides a CAN bus interface through a standardUSB
interface.
2.4 The t programming language
The Kvaser t programming language is event oriented and modelled after C. It canbe used
to customize the behavior of the Kvaser USBcan Pro 2xHS v2 and otherKvaser t capable
devices.
A t program is invoked via hooks, which are entry points that are executed at theoccurrence of
certain events. These events can be, for example, the arrival of specific CAN messages or a
timer expiration.
Like any Kvaser CAN interface, the Kvaser USBcan Pro 2xHS v2 can be used via
CANlib on a host computer. The addition of t programs running directly on the Kvaser
USBcan Pro 2xHS v2 makes it possible to react much quicker to CAN busevents (for
example to speed up file transfer protocols or to simulate missing hardware).
For more information, see the Kvaser t Programming Language guide that can be
downloaded at www.kvaser.com/download.

Kvaser USBcan Pro 2xHS v2 hardware
In this section you can read more about the CAN channels, power supply and LED
indicators.
3.1 Hardware installation
For the Kvaser USBcan Pro 2xHS v2 to communicate with the host computer, a
compatible version of the Kvaser driver and firmware must be installed.
After the driver has been installed on the host computer, the firmware may then bedownloaded
and installed on the Kvaser USBcan Pro 2xHS v2.
The latest version of the driver and firmware can be downloaded from
www.kvaser.com/download.
The driver is installed by running the file kvaser_drivers_setup.exe.
The Kvaser USBcan Pro 2xHS v2 may be inserted in any free USB socket on thehost
computer. You do not need to switch the power off before inserting or removing the
device.
For information on how to upgrade the firmware, see Section 4.6, Updating the
firmware, on Page 16.
3.2 USB connector
The Kvaser USBcan Pro 2xHS v2 has a standard USB type “A” connector.
Figure 2: A standard USB type “A” connector.
Connect the device to your computer using any high quality USB 2.0 certified

3.3 CAN channels
The Kvaser USBcan Pro 2xHS v2 has two CAN channels in two seperate 9-pinD-SUB
CAN connector (see Figure 3). See Section 4.4, CAN connectors, on Page 15 for
pinout information.
Figure 3: CAN connector on Kvaser USBcan Pro 2xHS v2
3.4 Power supply
The Kvaser USBcan Pro 2xHS v2 is powered from the USB port.
3.5 LED Indicators
The Kvaser USBcan Pro 2xHS v2 has one power LED and one traffic LED for eachCAN
channel as shown in Figure 4 on Page 11. Their functions are described in Section 4.1,
Definitions of LED states and colors, on Page 12.
As USB cables become longer they are more sensitive to EMI,
because they make a longer antenna that can pick up more noise.
These issues can be mitigated by using higher quality cables with
better shielding. Thicker cables tend to be better thanthin ones, and
braided shielding tends to be more reliable than only foil. Furthermore,
longer cables may introduce signal degradation and timing issues that,
if necessary, can be mitigatedusing shorter cable segments combined
with hubs that amplify the signal and handle delays on a per-cable
basis.

Appendices
In this section you will find technical information about the Kvaser USBcan Pro2xHS
v2 and its connectors.
4.1 Definitions of LED states and colors
A Kvaser device has two basic types of LEDs; Power and Traffic. These are dualcolored
as shown in Table 3. A device with multiple CAN channels has one TrafficLED for each
CAN channel. When the device has more than one channel a spaceand digit is added on
the label, CAN 1, CAN 2 etc. The red Traffic LEDs are alsoused to indicate errors by
using all red Traffic LEDs simultaneously.

Power
PWR
Green/Yellow
Traffic
CAN
Yellow/Red
Table 3: The different type of LEDs.
The following definitions is used to describe the state of an LED:
Off
The LED is off and no light is emitted.
Flash
The LED is lit up for a very short time. A single flash may be hard to seeand a
continuous set of flashes will look the same as On.
Slow Blink
The LED is repeatedly turned On and Off. The On and Off phase isequal
in time.
Fast Blink
The LED is repeatedly turned On and Off but with a higher frequencythan
Slow Blink. The On and Off time is still equal.
On
The LED is constantly emitting light.
Slow Waver
This is a variant of Slow Blink but instead of being Off, a second coloris On.
This is only possible with a dual colored LED.
Fast Waver
The LED is alternating between two colors as in Slow Waver butusing
a higher frequency.
Running
This means that all LEDs are lit, one at the time, in sequence with everycolor
available i.e. “Power green->Power yellow->Traffic 1 yellow->Traffic 1red-
>Traffic 2 yellow->Traffic 2 red->...”
As an example, "Slow Waver (Green/Yellow)" means that the LEDis slowly blinkingby
alternating between green and yellow.

The power should never be removed when firmware update is in
progress.
4.1.1
Interface mode
The device is in Interface mode when connected to the host computer via USB. If the
Power LED is showing a steady green light, the device is in Interface mode andworking
correctly. When connected to the computer for the first time, the Power LED will blink
slowly in yellow until the driver is installed and the device has received a USB
configuration.
When in Interface mode, if the Power LED is yellow for an extended period,
something is wrong. Please see Table 4.

4.1.2
Status of scripts
There are by default no LED indications showing the state of a t program. Instead,the
developer of a script can override any of the existing LEDs and create notifications as
needed when the t program is running, including program exceptions.
1This should not normally happen. If it does, please contact Kvaser support.
2This indicates low power supply, such as using an unpowered USB hub.
3The red Traffic LED indicating overrun will stay on until the device goes bus off.

4.2 Start and stop of t programs
All events that a t program will react to are specified using various event hooks. In effect,
these are functions which are called when the specific events occur. Amongother events,
the program can react to starting and stopping itself which this section describes. Read
the Kvaser t Programming Language guide that can be downloaded at
www.kvaser.com/download for more information.
The “on start” event will be triggered in the Kvaser USBcan Pro 2xHS v2 when anyof the
following occurs:
•
When a t program is started using the CANlib API (kvScriptStart()).
•
When a t program is started from another t program.
The “on stop” event will be triggered for running t programs during thecorresponding
cases:
•
When a t program is stopped using the CANlib API (kvScriptStop()).
•
When a t program is stopped from another t program.

4.5 CAN bus termination
Every CAN bus must be terminated with a 120 Ohm resistor at each end of the bus. The
Kvaser USBcan Pro 2xHS v2 does not contain any CAN bus termination,because their
inclusion could cause severe disturbance in a system which is already correctly
terminated.
For laboratory or testing use, the exact value of the termination resistors is not always
critical. Sometimes a single terminator is sufficient. For production, propertermination is
essential. If you see error frames on the bus, you should check the termination.

4.6 Updating the firmware
For the Kvaser USBcan Pro 2xHS v2 to communicate with the host computer,
compatible versions of the Kvaser CANlib (including driver) and firmware must be
installed.
The latest versions of firmware and drivers can be downloaded for free at
www.kvaser.com/download.
Connect the Kvaser USBcan Pro 2xHS v2 to your host computer
with the USB cable and start the update.exe application. A window opens showingthe
Firmware Update Instructions, read and follow those carefully.
To check the current firmware version, open “Kvaser Device Guide” which can be
found
in the Control Panel. Select “Kvaser USBcan Pro 2xHS v2” in the tree viewto the left,
and click on the channel. The firmware revision information now appears in the right
half of the window.
The absolute minimum firmware and driver versions needed in order to use KvaserUSBcan
Pro 2xHS v2 are listed in Table 8

4.7 Kvaser MagiSync
Time synchronization is needed to achieve accurate and precise time stamping between
several host computer-to-bus interfaces connected to one host computer.Since each host
computer-to-bus interface uses its on-board clock to set the time stamps.
Kvaser MagiSync is an innovative way to synchronize several different Kvaser USB
interfaces. You do not need external cables - you get instant synchronisation when you
connect the MagiSync enabled Kvaser USB device.
For this to work the Kvaser USB interfaces must reside on the same USB root hub.If they
do not they will not be synchronized, see Figure 6 on Page 17 and Figure 7 on Page 17.
Usually, a computer has a USB controller with one root hub in a computer. If you use
that one, you do not need an external USB hub to get your Kvaser Devices
synchronized. The easiest way to verify the setup is to view Synchronized Hardware in
the Device Tree of “Kvaser Device Guide” in your computer’s control panel. If all your
hardware is placed in one Kvaser MagiSync Group, then you areready to go.
When connected correctly, all units are synchronized achieving a high precisionvirtual
clock accurate to the microsecond.

4.8 Kvaser CANtegrity
Kvaser CANtegrity is an extension to the logic of the CAN FD controller that
provides deeper knowledge about each CAN frame. With this knowledge it is
possible to provide the following information:
•
A digital oscilloscope view on the CAN frames.
•
Bit length deviations over time.
•
Asymmetric propagation delays for dominant and recessive bits.
The Kvaser CANtegrity logic may run different event programs depending on whattype of
information that should be collected. As an example, one such event program will search
for CAN frames according to a defined bit rate and will record everything that looks like
a CAN frame, including Error frames.
Figure 8 shows an example of visualizing the information retrieved by the Kvaser
CANtegrity function included in the Kvaser USBcan Pro 2xHS v2 (00752-9). More
information about Kvaser CANtegrity can be found on https://www.kvaser.com/kvaser-
cantegrity/.
