Arctic GPRS Router 22 Viola Systems Ltd.
Ethernet
Configuration for the Arctic Ethernet Interface:
Override Ethernet configuration by DHCP – If this parameter is Enabled Arctic gets the IP
address and other related information from a local DHCP server. When enabled, all other
settings are disabled on this page.
Host name – Sets the Arctic device hostname. This is important to set up correctly when
using a Viola M2M Gateway and VPN. Every Arctic connected Viola M2M Gateway must
have unique hostname.
Domain name – Domain name for name resolution (optional)
Ethernet IP address – IP address used by eth0 interface.
Network mask – Network mask used by eth0 interface
Use Ethernet as default route – Set this to “Yes” only when using Ethernet as default
gateway/router. This parameter overrides next parameter “Default Route IP Address”, so as
long this parameter is set to no, next parameter has no affect. Usually this is set to “No”,
because either GPRS on VPN is used as default route.
Default Router IP address – Default router (or default gateway) used when the direct route
to host or network is not know. This parameter applies to eth0 interface only. When GPRS or
VPN is used as default gateway this parameter has to be set to 0.
MTU - MTU for Ethernet interface (usually 1500).
DNS servers (optional) - Name server IP (DSN) address for resolving host names to IP
address and vice versa. Applicable when GPRS parameter “DNS servers” is set to “User
defined”.
GPRS
GPRS settings include APN and other settings for GPRS network connectivity. More details of
GPRS connectivity is in Chapter 7.
GPRS enabled – When set to yes, GPRS interface is automatically attached to GPRS
network.
Access Point Name (GPRS) – GPRS Access Point (APN) name where the connection is
made.
PIN code– SIM card pin code.
DNS servers– When set to “User defined”, DNS servers from Ethernet page are used. If the
parameter is set to “From GPRS network” Arctic receives DNS server IPs automatically from
GPRS network.
Led indication – In Data only mode GPRS LED blinks green when transmitting data. In
Informative mode LED blinks also when connected to GPRS network without data transfer
(GPRS context is active).
GPRS username – Username used for authentication if APN requires it.
GPRS password – Password used for authentication if APN requires it.
PPP idle timeout – Maximum idle time for GPRS interface. If the GPRS interface has been
idle (no traffic) for this period, the GPRS connection is restarted.
