1 Introduction
The PCAN-Ethernet Gateway FD DR allows access to classic CAN or
modern CAN FD buses via an IP network. On top of that, CAN buses
can be connected to each other via IP using multiple devices. CAN
frames are wrapped in TCP or UDP message packets and then
forwarded via the IP network from one device to another. The
PCAN-Ethernet Gateway FD DR provides a LAN interface and two
CAN FD interfaces that allow bit rates up to 10 Mbit/s. For this, an
AM5716 Sitara processor provides the needed performance.
The PCAN Gateway product family is configured via a convenient
web interface. Alternatively, the JSON interface allows access via
software. Both options provide status information and settings of
the devices, the various communication interfaces, message
forwarding, and filters.

2.1.1 Activating the Internal Termination
A termination of 120 Ohm can be activated for each CAN channel
via solder bridges on the board. A High-speed CAN bus (ISO
11898-2) must be terminated at both cable ends with 120 Ohm each,
otherwise interference will occur. The termination is not activated at
delivery.
Tip: We recommend adding termination at the CAN cabling, for
example with termination adapters (e.g. PCAN-Term). Thus,
CAN nodes can be flexibly connected to the bus.
Do the following to activate the internal CAN termination:
Risk of short circuit! Take great care when soldering to avoid
unwanted short circuits.
Attention! Electrostatic discharge (ESD) can damage or destroy
components on the card. Take precautions to avoid ESD.
1. Disconnect the power supply (Power).

3 Putting into Operation
The PCAN-Ethernet Gateway FD DR is configured via a web
interface. Therefore, the module must be connected via LAN to a
computer, located in the same logical network as your gateway
(192.168.1.xxx).
3.1 First Connection to the PCAN-Gateway
During initial operation or after resetting to factory defaults, you
must pre-configure the PCAN-Gateway for your LAN. The default
login data is written on the label on the left side of the PCAN-
Gateway. Proceed as described in the following subsections:
3.1.1 Preparing the Computer
Your computer must be configured with an appropriate IP address
to connect to the device via LAN.
Do the following to determine your IP address:
1. Open the Windows Start menu.
2. Type ncpa.cpl and press Enter.
The overview of the network adapters appears.
3. Do a right-click on the adapter that will be used for the
connection to the PCAN-Gateway and select Properties.
4. Open the properties of Internet Protocol Version 4
(TCP/IPv4).

PCAN-Ethernet Gateway FD DR – User Manual

Do the following to change your IP address:
1. Make a note of the current settings in order to reset the
computer later on.
2. Select Use the following IP address.
3. Enter an IP address in the range from 192.168.1.1 to
192.168.1.254 (but not the PCAN-Gateway's own address
which is indicated on the left casing side).
4. Click on Subnet mask. 255.255.255.0 is shown. Leave this
entry unchanged.
5. Confirm the entries with OK.
3.1.2 Establishing the Connection
Do the following to establish a connection:
1. Connect the RJ-45 connector of the PCAN-Gateway via a
LAN cable (included in the scope of supply) directly to the
computer.
2. Connect the device to a suitable power supply (8 - 30 V).
3. Wait until the PCAN-Gateway is ready (Status LED is
blinking green).
4. Open a web browser on the computer.
5. In the browser's address bar, enter the address of the PCAN-
Gateway (see the label on the left side of the device).

This opens the configuration website.
6. In the upper right area of the configuration website you can
find the login.
7. Enter “admin“ for each the username and the password and
confirm with Enter.
The restricted area appears and you can start setting up the
PCAN-Ethernet Gateway FD DR. You can find a description
of the basic configurations in the following section 3.2.
Note: Afterwards, reset the computers IP address to the
previously noted address.

3.2 Basic Configuration
Change your login data first and then set up the PCAN-Gateway
connection to CAN and the LAN network.
3.2.1 Change Login Data
1. Open the page Device > User Management.
2. Change the login data on this page. Create a new username
and a new password.
To ensure a minimum level of security, the password should
have at least 8 characters. If possible, use letters, numbers,
and special characters.
Important notice: Login data is confidential! Do not act care-
lessly and leave your system open to attack. Never deposit the
login data in any form on the Internet or make it easily
accessible. Do not give the new login data carelessly to third
parties nor send it by e-mail.
3.2.2 Setting up CAN Channels
Do the following to configure the CAN channels:
1. Open the page Network > CAN.
2. Nominal Bit Rate: For setting the nominal bit rate, click the
drop-down menu and select the value that is used on the
CAN bus to be connected.
3. CAN FD: If the CAN bus to be connected uses the new
standard CAN FD, activate the checkbox CAN FD. The form
for selecting the data bit rate appears.
4. Data Bit Rate: For setting the data bit rate, click the drop-
down menu and select the value that is used on the CAN
bus to be connected.

5. ListenOnlyMode: If the PCAN-Gateway should act as a
pure observer, not affecting the data traffic, Listen-Only-
Mode must be enabled. Activate Listen-Only-Mode with a
click on the checkbox.
6. Confirm the entries with Save Settings.
3.2.3 Connecting to a LAN Network
Do the following to configure the IP address data of the PCAN-
Gateway for the LAN network to be connected:
Manual Address Assignment (Recommended)
1. Open the page Network > LAN.
2. If automatic address assignment via DHCP is not used, enter
the IP address and Subnet mask that the PCAN-Gateway
should use in the LAN network at the bottom of the page.
The gateway address can optionally be set.
3. Confirm the entered data with Save Settings.
You are automatically forwarded to the new IP address. The
basic setup of the device is now completed.
Automatic Address Assignment via DHCP
Note: DHCP is not recommended, because it is necessary to
know the IP address of the device to access the configuration
website. Furthermore, the IP address may change after a restart
of the device or the DHCP server. In this case the existing
routes won't work.
1. Open the page Network > LAN.
2. If the future LAN network uses DHCP (Dynamic Host
Configuration Protocol), the PCAN-Gateway IP address and

PCAN-Ethernet Gateway FD DR – User Manual
19
Subnet mask are assigned automatically. Enable DHCP to
use this feature.
3. Confirm the entered data with Save Settings.
You are automatically logged out and the basic setup of the
device is now completed. When the PCAN-Gateway is
installed in the LAN, it automatically receives its new
address data via DHCP.

3.3 Installing the PCAN-Gateway
Do the following to connect the device to an IP network
(Ethernet):
1. Mount the PCAN-Ethernet Gateway FD DR at the
appropriate position on the DIN rail by placing it at the top
of the rail and snapping it to the bottom.
Note: Please consider the recommended installation
distances to ensure a suitable air flow for cooling. When a
temperature limit is exceeded, the device is actively cooled
with a fan.
