2 Introduction
Since 1985, Kvaser has turned its full attention towards Controller Area Network and
associated technologies. Based in Sweden, Kvaser develops and manufactures innovative
and high performance PC interfaces for the global market.
2.1 Scope of this Document
This manual is applicable to the Kvaser products found in Table 1. Since the hardware is
essentially the same this guide will refer to all these devices as just USBcan II.
Please note the product names have been changed from USBcan II -S, -D to USBcan II -HS,
-HS/HS, -HS/LS, etc due the new product variants with support for Low-Speed and Single
Wire CAN.

2.2 General Description
Kvaser USBcan II provides a dual channel CAN bus interface with a standard USB interface -
one device for desktop and laptop.
The Kvaser USBcan II device is a USB 1.1 device. It also works with USB 2.0 in full-speed
mode, i.e. 12 Mbit/s. It contains the powerful M16C micro-controller from Mitsubishi with two
built-in CAN controllers. Kvaser USBcan II handles CAN messages with 11 bit (CAN 2.0A) as
well as 29 bit (CAN 2.0B) identifiers. Remote frames can be sent and received without
restrictions. It detects and generates error frames on the CAN bus. Kvaser USBcan II
provides two completely independent CAN channels with two separate connectors. The CAN
bus transceivers are integrated into the device.
All Kvaser USBcan II devices are also 100% compatible with applications using Kvaser’s
CANlib (i.e. applications written for LAPcan, LAPcan II, PCIcan, PCIcan II, PCcan, the old
USBcan, etc.) It enables you to run any applications using Kvaser CANlib API on any Kvaser
products, without the need of editing the code and recompile it. Example of supported PCI,
PC/104-Plus, USB and PCMCIA interfaces:
Kvaser PCIcanx II
Kvaser PCIcanx
Kvaser PC104+
Kvaser PCIcan II
Kvaser PCIcan
Kvaser PCcan
Kvaser Leaf Professional / SemiPro / Light
Kvaser Memorator II
Kvaser Memorator
Kvaser LAPcan II
Kvaser LAPcan
2.3 Kvaser USBcan II features
The Kvaser USBcan II is an improved version of the USBcan device. It is fully compatible
with the USBcan but features:
Improved performance
Light-weight plastic casing
Powered from either CAN bus or USB
Large on-board RAM buffer for CAN-messages.
Automatically switches power supply between CAN (primary) and USB (secondary),
to reduce power drain of laptop battery.
The second CAN connection can be ordered for High-Speed, Low Speed or Single
Wire CAN.

3 Kvaser USBcan II Installation
The Kvaser USBcan II is Plug and Play. Kvaser provide installation packages for major
operating systems, where each installation package contains all drivers for all Kvaser
hardware. You have two options to locate the appropriate installation package: the Kvaser
web site, www.kvaser.com, or the Kvaser CD that is shipped with your product. We do
recommend that you install the drivers before you connect the Kvaser USBcan II or any other
Kvaser product to your desktop or laptop. For detailed driver and hardware installation
instructions as well as firmware upgrades, please visit the Kvaser web site.
3.1 The USB connector
The Kvaser USBcan II device may be connected to any free USB socket that is present on
the host computer. You don’t have to switch the power off before inserting or removing the
device. It is good practice though to exit all applications using the CAN hardware before
removing the USBcan II.
You may use any high-quality standard USB cable to connect the device to the computer. The
USB cable that is included with the delivery is ca. 0.5 meters long. You can use USB cables
up to 5 meters (as specified by the USB standard.)
For USBcan II proper (all units in plastic housing) you need a USB cable with a type “B” plug
in one end and a type “A” plug in the other end.
If you want a longer cable for your USBcan Rugged, you can use an extension cable with a
type “A” receptacle in one end and a type “A” plug in the other end. Do not extend the cable to
more than 5 meters.

4 The Kvaser USBcan II hardware
This chapter describes the Kvaser USBcan II hardware.
4.1 Powering the USBcan II
You can supply power to the USBcan II in two different ways:
1. Through the USB connector
2. Through the CAN connector on channel 1
The USBcan II will use power from the CAN connector as its primary supply, that is, if you
supply power on both the USB connector and on the CAN connector, the USBcan II will use
the power from the CAN connector.
If you power the USBcan II through the CAN connector, you must supply 9 –30 V DC.
If you power the USBcan II through the USB connector, you must supply 5 V DC, as per the
USB specification.
4.2 Reference power
For USBcan II -HS/LS, -HS/SWC, you must also supply a reference voltage –the battery
voltage –(VBAT) on CAN channel 2, see Table 8 and Table 9.
4.2.1 USBcan II HS/LS
It is used by the transceiver to detect whether CAN_H and/or CAN_L are shorted to the
system voltage. The reference voltage is dependent on your system and must be in the
interval 5 –27 V DC.
4.2.2 USBcan II HS/SWC
The reference voltage is used as a reference voltage when transmitting and receiving
WAKEUP frames. It must be connected to ensure proper behaviour of the transceiver. The
maximum input voltage range is 6 –27 V. Operation above 12 V is not recommended.

4.3 The CAN Channels
The standard USBcan II has two independent I/O ports (CAN channels) depicted in Figure 1.
The first channel, Channel 1, is marked with ‘1’; the second, Channel 2, is not marked. See

4.6 CAN Channel Transceivers
The standard USBcan II has two high-speed (HS) channels with TJA 1050 drivers. As an
option the second CAN channel can be shipped with a Low-Speed or Single Wire CAN
transceiver, i.e. with a TJA 1054 or AU5790, respectively. The two CAN channels have 9-pin
male D-SUB connectors. The CAN bus is connected to the D-SUB connector, see Figure 5.
The D-SUB pin configuration for the HS, LS and SWC CAN channel is presented in Table 7,
Table 8 and Table 9, respectively.

4.7 Do’s and Don’ts
Do connect the ground pin on the D-SUB to the ground of your CAN bus.
If you power the device through the CAN connector, do connect the power to pin 9 on
channel 1.
If you are using USBcan II -HS/LS, -HS/SWC, do connect VBAT to pin 9 on CAN
channel 2.
Don’t extend the USB cable to more than 5 meters (you can use USB hubs if you
have to.)
Don’t go below 50 kbit/s on the high-speed CAN bus –the TJA 1050 transceiver will
not handle that.
If you are using USBcan II HS/LS, don’t go above 125 kbit/s on the low-speed
channel.
In case of trouble, do verify that you have at least one terminator on the CAN bus
unless you are using the LS channelSoftware Support
The Kvaser USBcan II boards are supported by drivers routines and program examples for
Windows, Linux, etc
