Sierra Wireless AirLink LS300
The target of the Airlink LS300 is the Alarming Module. Its purpose is to Send and Receive SMS
messages. Essentially, it is going to be utilized as an SMS gateway. As an example, Ignition picks up
information from a PLC that the water temperature is too hot. Ignition sends an SMS message via the
AirLink LS300 to contacts assigned to that alarm. It is received by a contact, which is then acknowledged
via SMS by the contact. This SMS message is sent back and received by Ignition via the AirLink.
LS300 and Network Security
The security settings covered here are basic steps to secure the LS300. Inductive Automation is not
responsible for the security of your LS300. You should take the time to configure and test the current
and other security measures as appropriate to your network.
Inductive Automation tested this router as a device that sits inside a network. Therefore, it needs to be
configured to act simply as another device on the network, not as a router or DHCP Server etc. Its sole
purpose is to handle SMS traffic.
Configuration and ACEManager
To access the modem’s configuration information and be able to change it, you will be accessing what is
called the ACEManager. This can be accessed via Ethernet, USB or Serial. This document will only cover
Ethernet access. The recommended browser to use is IE or Firefox. There are problems when using the
Chrome browser.
Setup Steps
The sections below should be followed in the order given to setup the AirLink LS300. Note that any
change that is made usually requires a reboot of the router/modem, which can be done through the
ACEManager. Follow these instructions and reboot at the end.
Default Ethernet Connection
First connect the LS300 directly to your computer and follow the manual’s instructions to connect to it.
Default Ethernet settings for access is the following:
Device IP Address:
Port: 9191
Username: user
Password: 12345
It should be as simple as changing your computer’s LAN settings to DHCP. Then connect to it via a
browser with the URL of

The first thing to check is if the router’s firmware is up-to-date. Go to the Status Tab. If the router’s
ALEOS Software Version is not 4.3.3a.014 (the latest firmware version as of this writing), it should be
updated. This can be found on the Sierra Wireless website at
With the firmware downloaded, follow these instructions to install it:
1) In the top right hand corner of the AceManager page, hit the Firmware link. This opens
up a window.
2) Browse to where the file is located, and hit update firmware. The update runs
The LS300’s manual also covers how to upgrade the firmware easily.
Setting up the AirLink to be on a network
The AceManager will be accessed to change the LAN and other setting to enable it to be accessed via an
existing network. After the firmware upgrade, you should still be able to access it via the default
Ethernet settings.
Go to the LAN – Ethernet Tab and change the following:
Device IP: <your IP Addr>
Starting IP: <your IP Addr> + 1 on last octet.
The last octet must be set to a number greater than what the Device IP is set to.
Ending IP: <you IP Addr> + X on last octet.
If DHCP Server Mode is disabled, setting this should not matter; however, set it to the Device IP
or higher.
DHCP network mask: or depending on your network.
DHCP Server Mode: Disable
The LS300 has a built-in DHCP Server. This must be disabled. If it is not, it may cause network
issues, creating conflicts on existing IP addresses already assigned.
The following is a screen shot example of the default LAN settings Inductive Automation is using – you
should adjust these as appropriate to you network:

After the above has been done, go to the LAN – Host Port Routing Tab. The router must be set to NOT
act as the gateway on the network.
Primary Gateway: Disabled
Failure to make the above setting may cause devices on the network to cease functioning.
Host network subnet mask 2:
Host network subnet mask 3:
Below is a screen shot of the changes:
ACEManager “Over-The-Air”
Page 3 of 7
By default the ACE Manager can be accessed “over-the-air”. If you load the Inductive Automation
default configuration, it is disabled. This will add security to the device to prevent access from outside
the network via the cellular network.
SSH Interface to the Modem
If you load the Inductive Automation default configuration, SSH is used in preference to Telnet. To SSH
into the router, use Putty or some other SSH Client. See Ethernet section for IP and login credentials.
Make the following changes in the Telnet/SSH section of the Services tab:
Remote Login Server Mode: SSH
Configuring SMS
In order to send SMS it must be enabled. Go to the Services – SMS tab.
SMS Mode: Control and Gateway

ALEOS Command Password: 12345
Local Host IP: this should be set to the IP of the Ignition Server.
Local Host Port: 17342
ALEOS Port: 17341
Port Filtering and Outbound Ports
To prevent outbound http and https traffic over the air from the LS300, port filtering is utilized. Under
Security – Port Filtering Outbound:
Outbound Port Filtering Mode: Blocked Ports
Filtered Ports:
Start Port 80 and End Port 0
Start Port 443 and End Port 0.

Trusted Inbound/Outbound IP Address
Using the AceManager, you can set certain Static IP addresses as trusted for both Inbound and
outbound traffic for the modem. If this router will be put inside a network, this option should be looked
Per the manual, Trusted IPs Inbound restricts access to the modem and all LAN connected devices. You
would use the Public IP Address that someone would be accessing the LS300 over the air.
Per the manual, Trusted IPs Outbound restrict access to external networks to IPs in the list.
Reboot the LS300
At this point in the setup, reboot the device. You should also be able to access it via the web interface
Using the AirLink and Additional Information
Sending & Receiving SMS Messages
To send SMS messages, login to the LS300 via SSH. The following is the basic command to send the
at*smsm2m="1XXXXXXXXXX This is SMS test message."
To see if the LS300 is receiving text messages, send one to it. Then from the ACEManager, go to Services
– SMS, and under the SMS Security–Inbound SMS Messages heading, there are 2 fields called Last
Incoming Phone Number and Last Incoming Message. Check if the number and message are there.
Press Refresh if you do not see it immediately.

Troubleshooting Notes:
To reset your device back to factory defaults in IE (this does not work using Firefox or Chrome), go to the
Admin - Advanced tab and hit the Reset to Factory Default button.
If the above doesn’t work:
 Hold down the reset button between 45 and 60 seconds. You will see the 4 lights flash
 When the device’s is resetting when all four lights flash yellow then red and then turn green for
about a minute before it boots up again.
