3. Getting Started
Unpacking the Arctic
Arctic is delivered in a bulk package containing only the device itself (with possible internal options).
A separate Arctic Accessory Kit (ordered separately) contains the following items:
•Power supply and cable
•Cross-over Ethernet Cable
•Null modem cable.
If any of the items are missing or are damaged, please contact Viola Systems Ltd. All packaging
materials are recyclable. Viola Systems urges its customers to follow environmental regulations
regarding the disposal of all materials.
Installation of the Arctic
The Arctic can be installed horizontally on a flat surface e.g. on a desk or a rack.
When installing Arctic models with wireless connectivity options it should be remembered that high-
frequency radio waves need to be taken into account. The surrounding environment affects the range
of radio signals. Therefore, if you are using an Arctic with antennas directly mounted to the antenna
connector, try to avoid placing the Arctic where the radio signal might be disturbed (“shadowed”) by
nearby obstacles. Also large metallic surfaces (racks) may have a highly detrimental effect on the
antenna performance. In case of metal racks or surfaces it is recommended to use an external
antenna with an appropriately selected cable. By following these precautions the Arctic may be
installed more freely.
The aluminum case of the Arctic contains rails for wall mounting. Both broad sides contain two rails
and the narrow side opposite to the LED panel contains one rail. These rails allow a flexible selection
of the optimum mounting direction. To mount the Arctic on a wall using optionally available mounting
tools can be used.

Arctic GPRS Router 15 Viola Systems Ltd.
Setting of the IP Address Using a Console
Before installation you need to find out the required network settings. These include the IP Address,
Netmask and Gateway Settings used by the Arctic. The local network administrator can provide
them to you or you can ask for them from your Internet Service Provider.
1. Before beginning, turn off the power from all devices and check that the power switch of the
Arctic is in the “OFF” position.
2. Connect a serial cable (crossover) to the console serial port (RS1) and an Ethernet cable to
the RJ45 connector.
3. Switch the Arctic on by toggling the power switch to “ON” position
4. Connect to Arctic using COM port and terminal program (Hyperterminal). Serial settings for
console (RS1) are 19200-8-N-1 and none handshaking”.
5. Stop the PPCboot to get the “Arctic>” command prompt. Set the IP address and netmask
using command “setenv”
Note: If possible, it is recommended to use an HTML browser to set up network settings as
described in the next chapter. If using a console, please follow the procedure below:

User’s Manual
Arctic GPRS Router 16 Viola Systems Ltd.
6. Save the setting with command “saveenv”.
7. Reboot the Arctic for the settings to take effect
Note: Default gateway value (gatewayip) is usually set to zero (0) because GPRS or VPN is
used as default router.

User’s Manual
Arctic GPRS Router 17 Viola Systems Ltd.
Setting of the IP Address Using an HTML Browser
This is the recommendable way to set up the network parameters. It is an easy-to-apply solution if the
computer used for configuration has been properly configured. Follow the procedure listed below:
1. Connect to the Arctic using your HTML browser. The default IP address of the Arctic is
“10.10.10.10” (netmask “255.0.0.0”).
Computer connected to Viola Arctic device can use for example IP address 10.10.10.11
2. From the initial page click Start Configurator and enter login information in the following page.
Username is root and by default no password is set (just leave the field empty).
3. Navigate to Network ÆEthernet page

User’s Manual
Arctic GPRS Router 18 Viola Systems Ltd.
4. Enter the Ethernet IP address (and other network settings) of your choice and click Apply and then
Commit (on bottom of page) to store the settings.
5. Reboot the Arctic for the settings to take effect.
Note: Arctic default password is empty. Remember to set the password before connecting the
A

4. Arctic Configurator Tool
The Arctic Configurator is a tool which allows the user to manage the properties of the Arctic device
by using a user-friendly, www-based interface. You only need a computer with an HTML browser and
a working connection to the Arctic to be able to use the web configurator.
With the Arctic Configurator you can set important parameters, receive status information, and set
variables that control which applications and processes run on the Arctic board.
Login to Arctic Configurator
To start using the Arctic Configurator, just open the URL in which the Arctic which you want to
configure is located. On the Viola Arctic main page, select the Start Configurator link.
First, the Arctic Configurator will ask you for the password for the Arctic device root-account. Enter the
correct password in the box provided and press the login-button to start the Arctic Configurator.
General Usage of the Arctic Configurator
After a successful login, the Arctic Configurator will display the main screen. This consists of the main
navigation menu on the top, the secondary navigation bar on the left, and the main screen containing
the currently active content and controls.
When first starting the program, the System/Information screen will be shown in the main content
area. The main navigation-menu on the top of the screen is used to navigate between the different
subsets of settings available. Selecting an item from the main menu will display the available items
Note: Default password for root is empty. Remember to set the password before connecting the
device to a public network. Password can be changed from SystemÆPassword menu
(Chapter 5)

related to this subset in the secondary navigation bar, selecting the first of these to be shown in the
main content area.
The secondary navigation-bar on the left contains the groups of parameters in this subset. Selecting
an item from this menu will display the content related to the selected group in the main content area.
In the bottom of the secondary navigation-bar is a group of three buttons which are always visible:
Commit , Reboot , and Logout. The Commit-button is used to save the memory-resident data for "soft"
parameters permanently to disk. Note that the values for the previous parameters are not saved to
disk unless the Commit-button is pressed. The Reboot-button, as the name suggests, will reboot the
Arctic. The Logout button will end the current session and return to the login-screen.
