Attention! The SPECTRE 3G router will not operate unless the cellular carrier has been
correctly configured and the account activated and provisioned for data communications. For
UMTS carriers, a SIM card must be inserted into the router. Do not insert the SIM card when
the router is powered up.
You can monitor the status, configuration and administration of the router via the Web
interface. To access the router over the web interface, enter http://xxx.xxx.xxx.xxx into the
URL for the browser where xxx.xxx.xxx.xxx is the router IP address. The modem‟s default IP
address is 192.168.1.1. The default username is "root" and the default password is "root".
The left side of the web interface displays the menu. You will find links for the Status,
Configuration and Administration of the router.
Name and Location displays the router‟s name, location and SNMP configuration (See SNMP
configuration). These fields are user-defined for each router.
For enhanced security, you should change the default password. If the router's default
password is set, the menu item "Change password" is highlighted in red.

If the green LED is blinking, you may restore the router to its factory default settings
by pressing RST on front panel. The configuration will be restored to the factory defaults and
the router will reboot. (The green LED will be on during the reboot.)
1.1. Secured access to web configuration
The Web interface can be accessed through a standard web browser via a secure HTTPS
connection.
Access the web interface by entering https://192.168.1.1 in the web browser. You may
receive a message that there is a problem with the website‟s security certificate. If you do,
click on “Continue to this website”. If you wish to prevent this message, you must install a
security certificate into the router.
Since the domain name in the certificate is given the MAC address of the router (such
addresses use dashes instead of colons as separators), it is necessary to access the router
under this domain name. For access to the router via a domain name, a DNS record must be
added to the DNS table in the operating system.
There are three methods to add a domain name to the operating system:
Editing /etc/hosts (Linux/Unix)
Editing C:\WINDOWS\system32\drivers\etc\hosts (Windows XP)
Configuring your own DNS server
You must then add a security certificate to the web server on the router. When using
a self-signed certificate, you must upload your files to the certs directory /etc/certs in the
router.

1.7. System log
Use the System Log menu item to view the router system log. The system log contains
helpful information on the operation of the router. Only the most recent information is shown on
the screen but older log entries can be viewed by saving the system log to a file and opening it
with a text editor. The Save button allows you to save the system log to a file. The system log
is cleared when the unit re-boots.
Fig. 7: System log
The Syslog default size is 1000 lines. When the system log reaches the maximum
size, it is deleted and a new log file is started.
The program syslogd can be run on the router to configure the system log. The
syslogd option "-s" followed by decimal number will set the maximum number of lines in the
log file. The "-r" option followed by the hostname or IP address will enable logging to a syslog
daemon on a remote computer.
On remote Linux machines, the syslog daemon is enabled by running syslogd with
the parameter “-r”. On remote Windows machines, a syslog server such as Syslog Watcher
must be installed.
To enable remote logging when the router powers up, modify the script
"/etc/init.d/syslog" or add the commands "killall syslogd" and "syslogd <options>" into
the startup script.
The following example shows how to send syslog information to a remote server at
192.168.2.115 on startup.

Select the LAN menu item to enter the network configuration for the Ethernet ports.
The main Ethernet port, ETH, is setup in the Primary LAN section. If the router has additional
Ethernet ports (PORT1 or PORT2), they are configured under the Secondary LAN section.
For routers with 2 additional Ethernet ports, PORT1 and PORT2 are automatically bridged
together.
Table 9: Configuration of network interface
The DHCP server assigns the IP address, default gateway IP address, and IP address
of the DNS server to the connected DHCP clients.
The DHCP server supports both static and dynamic assignment of IP addresses. In
Dynamic IP address assignment, the DHCP server will assign a client the next available IP
address from the allowed IP address pool. Once the lease time on an IP address has expired,
the DHCP server is free to re-assign that IP to another client.
Table 10: Configuration of a dynamic DHCP server
The DHCP server can also assign a Static IP address to a client. The MAC address
of the client must be configured in the MAC address table along with the desired IP address.
Up to 6 static IP addresses are supported. Do not overlap the static IP addresses with the
addresses allocated by the dynamic DHCP address pool. Otherwise, incorrect network
functioning may occur.

Description
Virtual Server
IP Address
This parameter sets the virtual server IP address. This address must be
the same for both the primary and backup routers. Devices on the LAN
will use this address as their default gateway IP address.
Virtual Server
ID
This parameter distinguishes one virtual router on the network from
another. The main and backup routers must use the same value for this
parameter.
Host Priority
The active router with highest priority set by the parameter Host Priority, is
the main router. According to RFC 2338, the main router should have the
highest possible priority - 255. The backup router(s) have a priority in the
range 1 – 254 (default value is 100). A priority value of 0 is not allowed.
Item
Description
Ping IP Address
Destination IP address for the Ping commands.
Ping Interval
Interval in seconds between the outgoing Pings.
Ping Timeout
Time in seconds to wait for a response to the Ping.
Ping Probes
Maximum number of failed ping requests
1.9. VRRP configuration
Select the VRRP menu item to enter the VRRP configuration. VRRP protocol (Virtual
Router Redundancy Protocol) allows you to transfer packet routing from the main router to a
backup router in case the main router fails. This can be used to provide a wireless cellular
backup to a primary wired router in critical application. If the Enable VRRP is checked, you
may set the following parameters.
Table 12: VRRP configuration
You may set the Check PPP connection flag in the second part of the window to
enable automatic test messages for the cellular network. In some cases, the PPP connection
could still be active but the router will not be able to send data over the cellular network. This
feature is used to verify that data can be sent over the PPP connection and supplements the
normal VRRP message handling. The currently active router (main/backup) will send test
messages to the defined Ping IP Address at periodic time intervals (Ping Interval) and wait
for a reply (Ping Timeout). If the router does not receive a response to the Ping command, it
will retry up to the number of times specified by the Ping Probes parameter. After that time, it
will switch itself to a backup router until the PPP connection is restored.
Table 13: Check PPP connection
You may use the DNS server of the mobile carrier as the destination IP address for
the test messages (Pings).
The Enable traffic monitoring option can be used to reduce the number of
messages that are sent to test the PPP connection. When this parameter is set, the router
will monitor the interface for any packets different from a ping. If a response to the packet is
received within the timeout specified by the Ping Timeout parameter, then the router knows
that the connection is still active. If the router does not receive a response within the timeout
period, it will attempt to test the PPP connection using standard Ping commands.

1.10.1. Cellular Carrier Selection
The SPECTRE 3G Cellular Router can be configured to communicate on up to 2
UMTS or CDMA cellular networks. This allows the router to switch to a second carrier
network if there is a problem with the primary network. The router can only communicate on
one cellular network at a time and if redundancy is not required, then only one account needs
to be activated. For UMTS networks, the account information will be on the SIM card
provided by the carrier. For CDMA networks, the account is provisioned by the network
provider and a SIM card is not required.
The cellular carrier is selected using the Cellular WAN configuration page. The router
supports AT&T, Verizon, Sprint, T-Mobile, and Rogers Cellular networks. Verizon and Sprint
have CDMA networks and the others are GSM networks. The default carrier is set to a
generic UMTS provider.
1.10.2. GSM/UMTS connection
If the Create PPP connection option is selected, the router will automatically try
to establish a PPP connection after power up. If the attempt is unsuccessful, the router will
re-boot and try again. For GSM/UMTS networks, the following network information can be
configured. In most cases, the necessary information will be included on the SIM card
provided by the carrier and these fields can be left empty or at their default values. Please

If the APN field is not filled in, the router will automatically select the APN based on the
IMSI code of the SIM card. If the PLMN of the cellular carrier is not in the APN list, then
default APN is “internet“. Contact your mobile operator to determine if the APN information
must be entered.
Access to the SIM card may be blocked if the PIN code for a locked SIM is entered
incorrectly. Contact technical support if your SIM card becomes blocked.
If only one SIM card is installed in the router, the router switches between the APNs on
the SIM card. A router with two SIM cards switches between SIM cards.
The items marked with an ‘*’ should only be entered if they are required by the cellular
network operator. If the router is unable to establish a PPP connection, verify that the

user to select which events will generate an SMS message.
Table 45: Send SMS configuration
You can also control the function of the router by sending SMS messages to the
device. The router can be commanded to go online or offline via an SMS message or to
switch to the alternate SIM card or provider. The binary outputs can also be set or reset
using SMS. The Enable remote control via SMS option must be selected to enable this
feature. Up to three numbers can be configured for incoming SMS messages. If the Enable
remote control via SMS option is set, all incoming SMS messages are processed by the
router and deleted.

Note: If no phone number is filled in, the router will accept incoming messages from all
phone numbers. If any phone numbers are entered into the list, the router will only accept
SMS messages which originate from those numbers.
Control SMS messages cannot change the router configuration. Any changes made
to the router by an SMS message will only remain in effect until the router is restarted. After a
reboot, the router configuration will return to the settings in non-volatile memory. For
example, if the router is switched offline by an SMS message, the router will remain offline
until the next time it is power cycled or re-booted.
To control the router using SMS, the message text must contain the control
command. Table 48 lists the SMS control messages that are supported.
Table 47: SMS Control Commands
You may send and receive SMS messages using either the serial expansion ports or
a TCP connection over the Ethernet network. For serial communication, the baud rate must
be set to match the attached host. Select option Enable AT-SMS protocol on expansion
port 1 to allow messages to be sent and received using serial port 1.
Table 48: Send SMS on serial PORT1 configuration
Select option Enable AT-SMS protocol on expansion port 2 to allow messages to
be sent and received using serial port 2.
Table 49: Send SMS on serial PORT2 configuration
It is also possible to send and receive SMS messages over a TCP/IP connection by
choosing Enable AT-SMS protocol on TCP port. The TCP port used for sending and
receiving SMS messages must be entered into the configuration field.

1.23.1. Send SMS
Standard AT commands are used to send and receive SMS messages over the serial
ports or a TCP connection. They can be sent to the router using a terminal program such as
Hyper Terminal. After establishing a connection with the router via the serial interface or
Ethernet, AT commands are used to read and delete incoming messages and send outgoing
messages. Table 52 lists the AT commands that are used for sending and receiving SMS
messages.
Table 51: AT commands to send and receive SMS messages
In order to send an SMS message, text mode must first be selected by sending the
command AT+CMGF=1 to the router.
Command: AT+CMGF=1
Response: OK
The SMS message is created and sent using the command AT+CMGS=”tel.

Description
Source
Select the location of the update files:
HTTP/FTP server – Remote file server.
USB flash drive - Router will check for firmware or configuration
files in the root directory of the connected USB device.
Both – Router will check for new firmware or configuration files in
both places.
Base URL
Base URL or IP address from which the configuration file will be
downloaded.
Unit ID
Name of configuration. If the Unit ID of the router is not filled in, then the
MAC address of the router will be used as the default file name. (The
delimiter in a MAC address is a colon instead of a dot.)
Update Hour
Automatic configuration update starts 5 minutes after turning on the router
and then every 24 hours at the Update Hour.
1.28. Automatic update configuration
The SPECTRE router can be configured to automatically check for firmware updates
from an FTP site or a web server and update its firmware or configuration information. Use
the Automatic update menu to configure the automatic update settings. It is also possible
to update the configuration and firmware through the USB host connector of the router.
If the Enable automatic update of configuration option is selected, the router will
check if there is a configuration file on the remote server, and if the configuration in the file is
different than its current configuration, it will update its configuration to the new settings and
reboot. If the Enable automatic update of firmware option is checked, the router will look
for a new firmware file and update its firmware if necessary.
Table 60: Automatic update configuration
The configuration file name is from parameter Base URL, hardware MAC address
of ETH0 interface and cfg extension. Hardware MAC address and cfg extension are added to
the file name automatically and it isn‟t necessary to enter them. When using parameter Unit
ID, the hardware MAC address in the name will not be used.
The firmware file name is named parameter Base URL, type of router and bin
extension.
It is necessary to load both files (.bin and .ver) to the HTTP/FTP server. If only the
.bin file is uploaded and the HTTP server sends the incorrect answer of 200 OK (instead of
expected 404 Not Found) when the device tries to download the nonexistent .ver file, then
there is a risk that the router will download the .bin file over and over again.

carrier and does not need to be manually entered. However, in some cases, it may be
necessary to set the phone number of the SMS service center in order to send SMS
messages. This parameter cannot be set if the SIM card already contains the SMSC
information. The phone number can be entered with or without an international prefix. For
example: +420 xxx xxx xxx. If you are unable to send or receive SMS messages, contact
your carrier to find out if this parameter is required. This parameter is provisioned
automatically by the carrier on CDMA networks and does not need to be manually entered.
Fig. 68: Set SMS service center address
1.34. Unlock SIM card
The SPECTRE RT industrial router does not support the Unlock SIM card option.
You may lock the SIM card with a 4-8 digit PIN (Personal Identification Number) code
to prevent unauthorized use of the SIM card. The PIN code must be entered each time that
the SIM card is powered up. The SPECTRE 3G router supports the use of SIM card with a
PIN number. Enter the PIN number into the SIM PIN field on the configuration page and
select Apply.
Access to the SIM card is blocked if the PIN code is incorrectly entered 3 times.
