Remote access removes boundaries, eliminates the need for time consuming site visits
and provides a network infrastructure suitable for today's “always-on” society. The ADSL­350 is an industrially designed ADSL broadband router built to cope with harsh environ­ments and the characteristics of industrial applications. The unit supports a wide range of
ADSL-standards and has support for long lines.

Most devices today comes equipped with an Ethernet port for communications, therefore
the ADSL-350 has a built-in two port Ethernet switch. For legacy connectivity the unit
also features one RS-232-port to provide multiple connection possibilities for both new
and legacy replacement installations. Designed to be installed on a DIN rail all connectors
and LEDs have been positioned in the front of the unit, facing the user for easy access
and fast status feedback. With the wide power input range the unit can be powered from
10 to 60 VDC and has low power consumption.

The cyber security features of the ADSL-350 prevent unauthorized access and secure the
communication for Internet-enabled applications. The easy to use firewall filters incom­ing traffic, allowing only approved packets to pass through. To inter-connect units with
each other securely over the Internet multiple VPN technologies are supported, including
IPsec and OpenVPN.

Upgrading legacy solutions to become IP-enabled can prove both costly and tedious
therefore the ADSL-350 includes a wide feature set for various legacy applications includ­ing both modem replacement methods as well as serial to Ethernet conversion. If there
are applications that require extra attention Westermo's extensive experience from
over 35 years within industrial data communications and over 5 years of industrial ADSL
expertise will be available to assist you.

STS LED – Status indicator

The status indicator reports the health of the unit. In normal operation the indicator will
be green, however, if a fault is detected, either at boot-up or during normal operation, the
indicator will light red. When the unit is first switched on or is reset the indicator will
first light red, then flash red in sequence with the SIG LED, this is normal behavior during
boot-up and does not indicate a fault.

Configuring a VPN connection in the ADSL-350 and activating the service will cause the
STS LED to be lit GREEN but FLASH RED every third (3) second to indicate that no
peer is connected on the VPN. The feature of the VPN status in the STS LED makes it
easy for staff to see whether or not the VPN connection is working without having to
login to the device.

SIG LED – Connection status

The Signal Strength Indicator reports the state of the ADSL network connection. The
ADSL sync speed is indicated by the number of green flashes of the indicator within
an indicator period. Each indicator green flash will be followed by a short off time, an
extended off time indicates the end of the indicator period.

an extended off time, the cycle will then repeat. The maximum number of flashes in an
indicator period is 6.

The indicator may be red during the extended off time following the green flashes indi­cating an ADSL network connection fault. The LED will be lit solid red if an ADSL con­nection cannot be established.

When the unit is first switched on, or is reset, the indicator will first light red, then flash
red in sequence with the STS LED, this is normal behavior during boot-up and does not
indicate a fault.

DSL LED – ADSL link status

The DSL LED reports the status of the connection to the network. When powered up
the indicator will be off, the indicator will then flash green whilst the unit tries to negoti­ate the link with the provider DSLAM, once successfully connected to the provider the
indicator will light green to indicate that everything is ready and functioning on the ADSL
link level.

Factory Default Reset Switch

The reset switch is used to restore the configuration of the ADSL-350 to the factory
default settings (for details about the default settings see the Getting started section).
The switch is accessed through a small hole, adjacent to the PWR and STS LEDs, labeled
C on the front of the unit.

To reset the configuration:

• Power down the unit.

• Using a suitable tool depress the reset switch.

• Power up the unit ensuring the switch remains depressed for approximately 5 seconds
after power is applied. The STS LED will flash twice (2) times to indicate a reset.

• Once the unit has booted-up it will use the default settings.

Note: Using the factory default reset switch will erase all existing configuration settings

and restore the factory default settings.

Power Supply

The ADSL-350 requires a DC power source in the voltage range of 10 to 60 VDC.
The unit is designed to self protect from permanent damage if the voltage exceeds
60 VDC or if reverse polarity is applied. The router may need to be returned for service
if this occurs. The router can also be damaged if there is any potential difference between
the chassis-ground, RS-232 signal ground, power (–) input, or antenna shield.
Before connecting any wiring, ensure all components are earthed to a common ground
point. An external isolator will be required if a positive earth power supply is used.

Step 8 – Configure the ADSL connection – part 1

Using your specific provider details you may need to change the VPI, and VCI settings
on this first screen.

When you have verified that the settings match, please click on Next.

Step 9 – Configure the ADSL connection – part 2
(Connection Type and Encapsulation)

On this page you use your Connection Type and ATM enc. settings. As before,
make sure these settings match the ones you received from your provider.

Step 10 – Configure the ADSL connection – part 3
(Extra settings depending on Connection Type)

In our example, using PPPoA, the following page is presented. If you are using another
Connection Type you will see a different page here.

Your provider will give you any username, password, and/or service name you might
need.

18

6623-2231

Complete the required fields for your connection and then click on Submit.
The ADSL-350 will then reconfigure the ADSL settings of the unit and set up
the connection. You can follow the process by either looking at the SIG and
DSL LEDs on the physical unit, or look at the ADSL Status page by clicking
on the top level menu Status, followed by the ADSL sub-menu.

Step 11 – Verify the Internet-connection

As the above screenshot shows, the ADSL-350 is now connected to the Internet and
has successfully received an IP-address from the provider. From the attached PC you
should now be able to access the Internet, verify by going to your favorite website
(e.g. westermo.com) using your browser on the PC.

The ADSL-350 is now ready to be used!

Note! The ADSL-350 is by default cyber secured by the built-in firewall, meaning that
any connections originating from the Internet is stopped in order to protect against
some of the online threats. Should you need to open up the firewall this can easily be
done by going to the top-menu Firewall, and then clicking on the Access Control
sub-menu. For more details about the firewall and how to setup other scenarios, please
refer to the Management Guide on the product website.

19

6623-2231

Additional configuration guides

In this section a few common use-cases and their configuration is listed. For more infor­mation about protocols and features of the ADSL-350 please refer to the Management
Guide on the Westermo product website.

Changing the default password

Westermo strongly recommend users to change the default password of the unit in
order to increase the security. Navigate to the top-level menu System followed by the
sub-menu Administration, once there, please click on the little pen-icon next to the field
Edit users and passwords.

After clicking on the pen, a new page will be shown where the password of both the
admin and guest* user. Unless the ADSL-350 should use a Radius server to centrally
authenticate the login, the Radius configuration details can be ignored.

Type in the current password of the user and then select a new secure password and
type it into both the New password field as well as the Confirm password field. Then
click on Update to activate the changes.

Note! The guest-user-account is by default disabled; once the password is set for the
guest user it becomes active.

20

6623-2231

Changing the LAN IP address

Sometimes the default IP address range does not fit the current IP plan of the application.
Changing the LAN IP address of the ADSL-350 is very easy. Start by navigating to the
top-menu Network, followed by the sub-menu LAN.

In the IP Address input box the default IP is listed, 192.168.2.200. Change this to the new
IP address that the unit requires and, if needed, also update the Netmask, then click on
Update. The ADSL-350 will then display a page with a link to the new IP address and then
change its IP, no reboot is required.

Note! Make sure the PC network settings are updated accordingly so that it is possible
to access the new ADSL-350 IP address.

Enabling the DHCP server

For easy administration the ADSL-350 can act as a DHCP server to any LAN connected
devices. The DHCP server allows clients on the local network to be automatically allo­cated IP addresses from the ADSL-350. The unit will also provide the clients with net­work settings like their default route and DNS servers.

To enable the DHCP server please navigate to the top-menu Network, followed by the
sub-menu LAN. By default the DHCP server is disabled but if enabled it will be config­ured to serve IP addresses in the range 192.168.2.210 through 192.168.2.240, and the
Default and Maximum lease times have been set to 1440 minutes. Should these values be
consistent with the network that the ADSL-350 is connected to, the DHCP server can
be enabled by ticking the Enabled field followed by clicking the Update button.

If the default settings do not match the application network, make the appropriate changes,
and remember to tick the Enabled box. Then click Update and the DHCP server is started.

For those that may need to configure static IP addresses based on attached devices MAC
addresses, the ADSL-350 will display a section for that once the server is started, i.e. after
ticking the Enabled box and clicking on Update.

Note! The DHCP server will automatically use the LAN IP address of the ADSL-350 as
the default gateway for clients.

21

6623-2231

Configure LAN clients to use the ADSL-350 as their gateway

The ADSL-350 will act as a gateway for connections destined to the Internet. The default
configuration will provide Network Address Translation and firewalling to protect clients
on the local network.

In order to configure any LAN clients to use the ADSL-350 as their gateway the follow­ing to methods can be used;

If the clients have a DHCP address allocated by the ADSL-350, they will have learned the
necessary settings. No further configuration is needed.

Or, if clients have static IP addresses, set their default route and DNS server to the IP
address of the ADSL-350, by default 192.168.2.200.

The ADSL-350 sometimes changes the ADSL IP address /
Our provider cannot offer us a fixed IP address

In some applications there is a need to connect to the ADSL-350 from the Internet,
either via a VPN (recommended) or by opening up the firewall for some specific services
/ ports. Either way, the connecting systems / devices need to know where to connect
to and if the service provider keeps changing the ADSL IP address that the unit receives
from their servers it can become a nightmare to constantly update any settings in the
systems / devices. Luckily there is a solution to this that is very commonly used on the
Internet and it is called Dynamic DNS, or DDNS.

It works in roughly the following way; once the ADSL-350 notices that it has a new
IP-address on the ADSL interface it will send an update to the DDNS service provider
that will update the domain name that have been associated with the unit.

The most common DDNS provider is called Dyn™ (earlier DynDNS ™) –

http://dyn.com – but there are others out there as well. The ADSL-350 supports a

few different providers that can be found on the configuration page of DDNS.
Register an account with the provider of choice and then configure a domain
name with that provider to be used on the ADSL-350. Then it is time to configure
the ADSL-350 to use the domain name so that it can be accessed instead of the
direct IP address, removing the need to actually know the IP address.

Navigate to the top-menu Network followed by the sub-menu DNS.
For the purpose of this example the following details will be used;

Domain name server.mine.nu

Finish and activate the settings by clicking on Update, the DDNS client will now
track the changes of the ADSL interface of the ADSL-350 and update the domain
server.mine.nu should the unit get a new IP address.

Note! Even though any changes usually are updated / replicated quite quickly, there can
be issues, e.g. at the DDNS service provider, that prevents updates, or introduces delays.
For more critical applications a fixed IP address may prove more reliable, or the use of
other methods to guarantee connectivity. Feel free to contact Westermo Support should
you have any questions about this, or refer to the Westermo website.

How can the ADSL-350 be configured from the Internet?

In some scenarios the user might want to configure the ADSL-350 from the Internet,
either by accessing a DDNS name, or using a fixed IP address from a PC on the Internet.
Since the ADSL-350 is cyber secured by a firewall by default, the user must first allow
traffic from the Internet trying to access the web-interface / webserver of the ADSL-350
to pass through.

Westermo strongly recommends any user opening up the firewall to change the default
password of the ADSL-350 before doing so.

To open the ADSL-350 for access to the web-interface from the Internet just navigate to
the top-menu Firewall followed by the sub-menu Access Control.

status. In our example we wanted the unit to respond to incoming requests destined to
the web-interface on the ADSL interface IP (DSL-1). Just tick the Allow tickbox and then
click on Update. The settings are activated immediately and the ADSL-350 can now be
accessed from the Internet.

How to access a device connected to the LAN or Serial port of the ADSL-350
/ How to open up a port in the firewall.

For any type of communication with devices connected to the LAN ports, or the Serial
port, Westermo strongly recommends the use of Virtual Private Networks (VPNs). Refer
to the product website at Westermo for application notes and the detailed Management
Guide for more information about VPNs.

Sometimes there may be a need for a simpler, but less secure approach, either for test­ing or for non-critical applications. With the use of portforwarding a connecting system /
device can use the IP address of the ADSL-350 to communicate with devices attached to
the LAN, or Serial, side of the unit.

In our example an HMI is connected to the LAN port of the ADSL-350, and has been
configured with the ADSL-350 as its default gateway;

The HMI has a built-in webserver on TCP port 80, our goal is to access the HMI’s
webserver from the Internet on our laptop.

Start by configuring a DDNS account, and a domain name, for this example the
server.mine.nu name will be used. Once DDNS is configured in the ADSL-350 it is
time to create a firewall rule that allows traffic coming from the Internet to the
ADSL-350 on a specific port to be forwarded to the HMI. For the purpose of this
example the incoming port that the PC will be using is 12345.

Navigate to the top-menu Firewall followed by the sub-menu Port Forwards and then
click on Add new port forward. In the screenshot below the information above has
been used to create a port forward to the HMI. The user on the laptop would open his
browser and type in the domain name followed by a colon and then the custom port, e.g.

http://server.mine.nu:12345.

Once Update is clicked the port forward is active. If the HMI has been configured
properly it would now be accessible.

Note! If the connected LAN device, e.g. the HMI or PLC, does not have the possibility
to set a default gateway the use of 1:1 NAT can be used. For more information about
how to achieve this please refer to the Management Guide.
