1Introduction
The PCAN-USB Hub provides several hardware interfaces via a USB
connection. The device has connection facilities for one CAN bus,
two serial RS-232 connections, and two additional USB devices.
Device drivers and programming interfaces exist for different
operating systems, so programs can easily access a connected CAN
bus.
Tip: At the end of this manual (Appendix C) you can find a
Quick Reference with brief information about the installation
and operation of the PCAN-USB Hub.
1.1 Properties at a Glance
High-speed USB 2.0 hub with
•USB to CAN interface, connection through 9-pin D-Sub
(in accordance with CiA® 102)
•Two USB to RS-232 converters using two
D-Sub connectors (9-pin)
•Two High-speed USB 2.0 downstream ports
Passive (bus-powered) hub operation through the USB port of a
PC enables power consumption of up to 100 mA per USB
channel
Active (self-powered) hub operation through the optional
external hub power supply (9 - 36 V) enables power
consumption of up to 500 mA per USB channel
Guaranteed high transfer rates on all channels if a Full-speed
device is connected, thanks to a hub controller with 4
transaction translators

2Installing the Software and
the Adapter
This chapter covers the software setup for the PCAN-USB Hub
under Windows and the connection of the hub to the computer.
Drivers for the CAN interface as well as the RS-232 interfaces are
installed.
Setup the driver for the CAN interface before connecting the PCAN-
USB Hub to the computer for the first time.
Do the following to install the driver for the CAN interface:
1. Windows XP only: Make sure that you are logged in as user
with administrator privileges (not needed for normal use of
the PCAN-USB Hub later on).
2. Insert the supplied CD into the appropriate drive of the
computer. Usually a navigation program appears a few
moments later. If not, start the file Intro.exe from the root
directory of the CD.
3. On the page English > Drivers activate the entry PCAN-USB.
4. Click on Install now. The setup program for the driver is
executed.
5. Follow the instructions of the setup program.
Tip: If you don't want to install the CAN monitor PCAN-View for
Windows onto hard disk together with the driver, you have the
option to start the program later directly from CD without prior
installation.

Do the following to connect the PCAN-USB Hub and carry out
the initialization of the CAN driver and the installation of the
drivers for the RS-232 interfaces:
Note: Do not use a USB extension cable to connect the PCAN-
USB Hub to the computer. The use of an extension cable does
not comply with the USB specification and can lead to
malfunction of the adapter.
1. Connect the PCAN-USB Hub to a USB port at the computer.
The computer can remain powered on.
Windows notifies that new hardware has been detected.
2. Windows XP only: A Wizard dialog box appears. Follow its
instructions. Deny the search for driver software at
Windows Update and select the automatic software
installation during this procedure.
3. Dialog boxes appear for the installation of the drivers for the
RS-232 interfaces (devices “USB <-> Serial Cable” and “USB
Serial Port”). Follow their instructions. Select the search for
driver software on CD during this procedure.
All Windows operating systems: The drivers are found and
installed by Windows.
4. Afterwards you can work as user with restricted rights
again.
After the initialization process for the driver for the CAN interface is
finished successfully the red LED at the CAN connector of the
PCAN-USB Hub is illuminated.
