Installation and Configuration
Electrical Connections (refer to hookup diagram
insert)
Connect the ILF-100 to a 12V (500mA or greater)
regulated DC power supply.
Connect the relay terminals to a cellular backup dialer. The
relay terminals are labeled NC (Normally Closed), COM
(Common) and NO (Normally Open). Since cellular
dialers vary, you will need to refer to your cellular backup
dialers hookup instructions for details on the proper
hookup.
To use the optional User Input (MNTR IN), connect a
common ground wire between the device being monitored
and the ILF-100. Connect MNTR IN terminal to the
devices output. The MNTR IN can accept any DC voltage
between 5V and 24V. If the device uses open-collector
outputs, a user-supplied pull-up resistor must be connected
(see lower left detail in the hookup diagram). See User
Input
in the ILF-100 Configuration section for details on
enabling email notices for User Input state changes.
One or more Server Fail outputs may be used to trigger
visual or audible indicators for individual servers that may
fail. The total current drawn by these outputs must not
exceed 400mA. Note that these are open-collector outputs,
which means they must be connected to the - terminal of
the device being switched. The 12V AUX terminals may
be used for powering the + terminal of the device. See
the hookup diagram for an example.
Connect the ILF-100s Ethernet controller board to an open
port on a router or Ethernet switch using the supplied
network cable
.

Network Configuration
If you are only concerned with detecting a failed internet
connection and do not need any of the email notification
features, you may simply plug the ILF-100 into a DHCP-
enabled router and connect the relay terminals to your alarm
systems backup communication device. No further
configuration is needed!
The ILF-100 is designed to be connected to a network router. It
must initially be configured using a web browser on a computer
that is connected to the same router (i.e., on the same local area
network). In order to connect to the ILF-100, its IP address
must be known. The easiest method for determining the IP
address is to connect the ILF-100 to a network that uses DHCP
(Dynamic Host Configuration Protocol) and allow it to send the
sign-on email to the mailing list at
www.ILF100.com
. Virtually
all home routers support DHCP. Even if a static IP address is
going to be assigned to the ILF-100, the network configuration
will go much smoother if DHCP is initially used. The other
(more difficult) method is to connect the ILF-100 directly to a
computer using a crossover cable. If your network does not
support DHCP, see the section entitled, Fallback Method
Using a Crossover Cable
detailed in the extended online
manual posted at
www.ilf100.com/ILF100Manual.pdf
.
DHCP Method
1.

Connect the ILF-100 to your network using the supplied
CAT5 patch cable.
2.

Power up the ILF-100 and observe the LEDs on the
Ethernet control module (the very small surface mount
LEDs located next to the RJ-45 connector). The green
LED should be steadily illuminated and the yellow LED
should occasionally blink to indicate network activity.
3.

The green E-MAIL LED (located on the main circuit
board) should illuminate after a few seconds, indicating
that the sign-on email was successfully sent.
4.

Using a computer with an internet connection, type
http://archives.ILF100.com
into the address bar of a web
browser. Stealth Labs ILF-100 User Manual

5.

Click on the archive for the current date by clicking the

link.
6.

Newest emails appear at the bottom of the list, so you may
simply find your email listed there.
a.

If the email list is quite large, press <Ctrl> F to open
the search dialog box in your web browser and type in
the serial number of your ILF-100. The serial number
is printed on the bar code label that is affixed to the
chips on the top side of the Ethernet controller board.
b.

Click the Find button of the dialog box.
The browser should highlight the subject line of the
email that your ILF-100 just sent
7.

Click on the message link to view the email body.
8.

Click the link after IP Addr: to access your ILF-100s
configuration page. Security Note: this link will only
work for users connected to the same LAN as your ILF-
100
.
9.

You should see a password dialog box similar to Figure 1.
10.

Enter admin for the User Name and pass for the password.
Both are case sensitive.

11.

If you were successful, you should see the ILF-100
configuration screen, illustrated in Figures 2 - 6.

Text To Identify This Unit
The first section is shown in Figure 2. This text field allows the
user to describe / name the ILF-100 or the location in which it is
installed. All emails sent by the ILF-100 will include this text
in the body of the email to help clarify which unit sent the
email. This text may be up to 25 characters in length.
Text To Identify This Unit
This text will be displayed here and in the body of all emails:

Network Settings
The Network Settings section is shown in Figure 3. The LAN
and WAN IP addresses are displayed at the top of the section.
If the ILF-100 has not yet connected to the internet, the WAN
IP will be displayed as 0.0.0.0, otherwise it will display the IP
address that was assigned to the router by your broadband
Internet Service Provider. If the ILF-100 was able to connect to
a DHCP server, the LAN IP address will display the IP address
that was assigned to it by the router. If no DHCP server was
found, the fallback IP address of 192.168.1.10 will be
displayed. Stealth Labs ILF-100 User Manual

Manually Assigning an IP Address
If your network does not use DHCP, or if you plan on being
able to access the ILF-100 from remote locations, you will need
to manually assign an IP address. Note that some routers allow
static IP addresses to be assigned while still using DHCP. If Stealth Labs ILF-100 User Manual
