Installation of the device
2 Installation of the device
2.1 Connections of the CAN@net
The following diagram shows the connections of the CAN@net. The pin alloca-
tions are described in detail in section 5.
The CAN@net also has four LEDs. For the three communication connections
Ethernet, CAN and RS232, one Duo-LED each is available with which the com-
munication status of the interface can be read off. When connected to the volt-
age supply, the Power LED is illuminated.

2.2 Preparation of configuration
Before initial commissioning of the CAN@net, the device must be configured. For
configuration you require a standard PC with a terminal program (e.g. Windows-
Hyperterminal). First carry out the following steps to prepare the device for con-
figuration:
(1) Connect the first serial interface of the CAN@net with a serial port of your
PC with a null modem cable.
(2) Start a terminal-program on your PC with baud rate 19200 baud, 8 bits, no
parity, 1 stop bit (or the last configured baud rate of the CAN@net).

Installation of the device
(3) Connect the CAN@net to the voltage supply (9V-36V DC on pin 1,2 of the
Power plug). Now the CAN@net boots which it also indicates by blinking
the green function LEDs (RS232, CAN, Ethernet), one after the other.
(4) After the boot process the CAN@net prompts a dialog via the serial connec-
tion to the terminal emulation. Within 10 seconds press any key in order to
start the configuration dialog.
(5) Carry out configuration of the device as described in section 3. If you wish to
use the CAN@net in a network with DHCP server, you have to enter the
MAC ID of the device in the DHCP server. The MAC-ID of the device is fixed
to one side of the CAN@net with a sticker.
(6) Restart the
CAN@net by disconnecting the voltage supply and reconnecting.
The set parameters from the configuration are adopted. With the “Ping”
program, you can test whether the CAN@net can be accessed under the
configured IP address.
2.3 Commissioning a configured device
The configured CAN@net is commissioned with the following steps:
(1) Connect the CAN@net to the voltage supply (9 V- 36 V DC on pin 1,2 of
the Power-plug). First the communication LEDs are alternate blinking green,
in this case the firmware is copied from flash to DRAM. Afterwards the CAN
and the Ethernet LEDs are flashing green and red. The Serial LED is flashing
green, the gateway is now in the configuration mode.
(2) Establish the Ethernet connection and the connection to the CAN network. If
the connection to the Ethernet has been carried out correctly, the Ethernet
LED flashes when receiving/transmitting Ethernet packages. The CAN LED
flashes green if messages are received/transmitted via CAN messages.
(3) The
CAN@net is ready for operation and can be initialized via the connected
network. If the CAN@net is to be initialized via the Ixxat driver software VCI,
the VCI software package must be installed on your computer. For this, see
the VCI Installation Manual.

Configuration
3.3 Settings of the network parameters
The settings for IP are made with the network configuration. If the network pa-
rameters should not be changed, you can skip to the next configuration:
Change the network configuration?[N]
The network configuration can be skipped with <ENTER> or 'N'+<ENTER>.
These further network configuration dialogs are branched into by pressing
'Y'+<ENTER>.
For the function of the Internet protocol, the device must have the own IP ad-
dress, subnet mask and the address of the gateway. These settings are made with
the following dialogs.
3.3.1 DHCP setting
The DHCP client can be set up on the CAN@net via the DHCP setting. The DHCP
client obtains the IP address automatically via a DHCP server, so that no further
network settings are necessary. The condition for this is that the network in which
the CAN@net is used has a DHCP server service.
Should this device use DHCP to obtain
its IP settings automatically?[N]
By entering Y+<ENTER>, the DHCP-client of the CAN@net is activated and will
obtain the configuration from a DHCP-server after a reset. No further network
configurations are required.
By entering N+<ENTER>, the DHCP-client is deactivated. IP address and subnet
mask must be entered manually.
3.3.2 Configuration of the IP address
The IP address of the CAN@net is configured with the following configuration
dialog:
IP address[192.168.10.22]?
Entry is made in the IP address notation: 4Byte in decimal representation sepa-
rated by dots in each case (see displayed IP-address). Entry must be completed
with <ENTER>. <ENTER> without any further entry accepts the IP address given
in brackets.

Configuration
3.3.3 Configuration of the subnet mask
The subnet mask states which part of the IP address describes the network. All
bits set to 1 in this mask mark the network part of the address.
Subnet mask[255.255.255.0]?
To change the subnet-mask, the mask is entered in the IP- address notation. If
the mask is to be retained, acknowledgement is made with <ENTER> without
any further entry.
3.3.4 Configuration of the gateway address
If the network consists of several subnets connected via gateways, the IP address
of the default gateway or of the default router must be entered.
Gateway address[192.168.10.254]?
To change the gateway address, the address is entered in the IP-address notation.
To retain the displayed address, the value in brackets is acknowledged with
<ENTER> without any further entry.
3.4 Configuration of the root password
For access to the gateway the root password is necessary. The password can con-
sists of a maximum of 19 characters. This could be letters, numbers or special
signs.
Do you want to change the root password?[N]
By entering <ENTER> or N+<ENTER> the configuration of the password can be
skipped.
With Y+<ENTER> the configuration is started.
Enter root password for access:
Please enter the already root password. After entering the password press <EN-
TER>.
Success, access granted…!
The entered password was ok, the configuration of the password can go on.

Configuration
Access denied!!
The entered password wasn’t ok, so the configuration of the password is termi-
nated.
Enter the new root password with maximum 19 digits.
Now the new root password should be entered. After writing the password press
<ENTER>.
Please enter the new root password once again.
For verification pupose the new password have to be entered again.
Success, password will be changed…!
If both entered passwords are the same, the new password will be saved. The
saving to the flash memory will take place after completion of the configuration.
So if the gateway is now disconnected from the power, the former password is
still active.
Without the correct password the gateway can’t be accessed. If the password is
lossed, the gateway have to be returned to the manufacturer to restore it.
3.5 Hardware Configuration
In the hardware configuration, settings for the serial interface and the delay time
to start the configuration dialog can be made.
Change the HARDWARE configuration?[N]
The hardware configuration can be branched into via 'Y'+<ENTER>. With <EN-
TER> or 'N'+<ENTER>, this configuration dialog is skipped.
3.5.1 Setting the baud rate for the serial interface
The setting of the baud rate only applies to the first serial interface (COM1),
which is used for the configuration.

Configuration
The baud rate is entered in bits / second. A maximum of 57600 bits/s is sup-
ported. When changing the baud rate, ensure that the new baud rate is sup-
ported by your terminal program. The new baud rate is completed with <EN-
TER>. The baud rate currently set is retained of the value in brackets is acknowl-
edged with <ENTER> without any further entry.
3.5.2 Setting the delay time of the configuration dialog
The delay time of the configuration dialog shows how long the CAN@net waits
for a key to be pressed by a terminal before the standard software starts.
How long (in seconds) should the CPU wait
before starting the application[10]?
The delay time is given in seconds and is accepted with <ENTER>. If the currently
set delay time is to be retained, the value in brackets is acknowledged with
<ENTER> without any further entry.
3.6 Saving the changed data
After ending the hardware configuration dialog, all parameters are saved inde-
pendent of changes in the Flash. During the saving process, the following mes-
sage appears:
Saving the changes in NV memory...Done.

Software Update
4 Software Update
This section describes updates of software via the serial interface. To do an up-
date, the flashloader utility from IXXAT is required.
4.1 Update via the serial interface
The IXXAT flashloader utility provides two batch jobs to ease the task. One
(fload1.bat) is prepared to do a firmware download via the PC COM1 and the
other (fload2.bat) is prepared to do it via the PC COM2.
1. Connect the CAN@net serial port via a null modem - cable (the one which
was part of the delivery) with the PC COM of your choice.
2. Run the batch job which corresponds to the COM port you are using.
3. Do a power cycle with the CAN@net. This starts the Bootmanager which
sees the waiting batch job on the serial connection and starts the flash
download.
4. The batch job prompts its progress and issues a success or failure message
when finished.
Caution: The batch job is prepared to work with the default baudrate of 19200
Baud. When you changed the settings of the baudrate for the CAN@net, these
changes must be done to the batch jobs as well.
