CAN@net II - Manual, V1.7
Introduction

1 Introduction
1.1 Overview
Congratulations on your purchase of the PC/CAN interface CAN@net II, a high-
quality electronic component developed and manufactured according to the
latest technological standards.
This manual is intended to familiarize you with the device. Please read this
manual before beginning with the installation.
For miscellaneous applications HMS offers different versions of the
CAN@net II.
As a TCP/IP based PC/CAN interface for standard Windows applications the
CAN@net II/VCI is the best choice. It offers with the IXXAT standard Windows
driver interface VCI an easy to handle and wide functional interface for Windows
applications. The IXXAT tools also use this standard driver interface.
The CAN@net II/Generic offers with a generic ASCII interface via TCP/IP the
possibility to use the device in non-Windows systems such as Linux operating
systems. Additionally, two CAN@net II/Generic devices can be used as a
bridge. This makes it possible to connect two CAN networks which are far away
from each other via TCP/IP. The CAN@net II/Generic devices receive the CAN
messages of their CAN network and transmit them via TCP/IP to the other
CAN@net II/Generic device. Filters can be set on configuration of the bridge, so
only messages which are interesting for the other network are exchanged.
For the different CAN@net II versions, specific manuals are available. This
manual describes the software installation and the programming and integration
of the devices into customer applications.

2 Installation
2.1 Software Installation
To operate the CAN@net II/VCI interface, a driver is required. This driver is part
of the VCI (Virtual CAN Interface), which can be downloaded for free from the
HMS website (http://www.ixxat.de).
For the installation of the CAN driver VCI under Windows, please refer to the
VCI installation manual.
For the CAN@net II/Generic bridge mode, the devices have to be configured.
This is described in detail in the CAN@net II/Generic manual.
2.2 Hardware Installation
The CAN@net II device needs a power supply and an Ethernet connection.
There is no further hardware installation necessary.
The CAN@net II can be plugged and unplugged during operation of the PC (hot-
plug compatible).
It is recommended to install the VCI software before plugging in for the first time.

3.3 CAN Bus Termination
There is no bus termination resistor for the CAN bus assembled on the
CAN@net II.
As an accessory a bus termination resistor is available as a feed through
connector at HMS (ordering number 1.04.0075.03000).
4 Configuration
4.1 Configuration Tool
4.1.1 Overview
The configuration tool, which is installed automatically with the VCI, is used to
set the network parameters of the CAN@net II.
The tool scans the network for CAN@net II devices. The detected devices are
shown in the “Device List” and can be configured separately.
Picture 4-1: Configuration tool

CAN@net II - Manual, V1.7
Configuration
15
4.1.2 Usage
When the configuration tool is started, the network is scanned for CAN@net II
devices. If a device is connected to the network later, there are two possibilities
for detecting the new device:
•activating the function “Autoscan”, so that the tool scans the network every 3
seconds, or
•pushing the “Rescan” button for a single network scan.
For configuring the network parameters of a CAN@net II, the desired device
has to be chosen from the “Device List”. After that, the “Configure” button has
to be pushed. This is only possible if the device is not connected to another
application (Connection State: Not Connected).
In the configuration dialog, the DHCP mode can be activated or deactivated.
The IP address, the subnet mask and the gateway can only be set in the non-
DCHP mode. In addition, the hostname and the password can be set.
When “OK” is clicked, the parameters are written to the CAN@net II. For
successful operation, the password has to be entered. The configuration can be
stopped with “Cancel”.
The default settings of the network parameters are shown in the appendix.
4.2 Resetting the Network Parameters
The default settings of the network parameters can be reloaded using the DIP
switch.
The following steps are necessary:
(1) Ensure that you are electro-statically discharged.
(2) Switch off the CAN@net II and unplug the power connector.
(3) Separate the top housing (incl. printed board) from the bottom housing. For
this, the two package locks have to be pressed in slightly.
(4) Switch number 1 of the DIP switch to “ON”.
(5) Put the printed board back in the bottom housing. Pay attention to the ESD
plastic film, because it has to be assembled.
(6) Connect the CAN@net II to the power supply. A green and red running light
has to be displayed by the LEDs PWR, CPU, ETH and CAN.
(7) Disconnect the CAN@net II from the power supply.
(8) Remove the PCB from the bottom housing in a similar way to the steps
described above.
(9) Switch number 1 of the DIP switch back to “Off”.
(10) Put the printed board including the ESD plastic film back in the bottom
housing. Ensure that the package lock is active again.
