■Pin 1 is positive (+)
■Pin 2 is negative (–)
The unit is protected against reversed polarity.
Power Switch
Enables or disables the operation of the Arctic.
Console Enable Switch
Enables or disables console access. When it is disabled, both serial ports may
be used as an application serial port. When the switch is in the right position,
RS1 is in serial port mode and when in the left position, RS1 is in console
mode.

3 Getting Started
3.1 Unpacking the Arctic
Arctic is delivered in a bulk package containing only the device itself.
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 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 the materials.
3.2 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.
3.3 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:

User's Manual
Arctic GPRS Gateway
Firmware Version 5.0.7 19 Document Version 1.6
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.
Figure 10. IP Properties
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).

User's Manual
Arctic GPRS Gateway
Firmware Version 5.0.7 20 Document Version 1.6
3. Navigate to Network -> Ethernet page.
Figure 11. Ethernet Settings
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 Arctic device to a public network (Chapter 5).
3.4 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.
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:
1. Before you start, 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.
