1. MTR-LVW2/MTR-LAT1 Install Guide

NOTE: The MTR-LVW2 and MTR-LAT1 require WIN-911 version 3.18.2 or newer. If you're not sure which version of WIN-911 you have, check to Add/Remove Programs for the version number of the WIN-911 Navigation module.

This guide will walk through the installation and setup of the Multi-Tech's MTR-LVW2/MTR-LAT1 for use with the WIN-911 SMS Notifier module to send and receive text messages.

WIN-911 communicates with Multi-Tech's MTR modems either through an Ethernet or Serial interface. For this document, our focus will be connected via the Ethernet port which can be connected either directly to the PC running WIN-911 or a network switch within your LAN. Accessing to the modem through a LAN means you won't need to connect the modem directly to the PC which provides a solution for VM environments when you're not able or prefer not to connect hardware to your host.

A. Activation / SIM Card Info

Before configuring WIN-911 to use your modem, you will need to set up a wireless account with a cellular provider (e.g. AT&T, Verizon) and obtain a Standard SIM card

Verizon users will need to provide Verizon with the IMEI # of your modem which can be found on the label affixed to the bottom of the modem.

WIN-911 will potentially send many text messages so we recommend subscribing to an unlimited texting plan to avoid overage charges. Neither a data nor voice plan is required for use with WIN-911.

It is possible to install the modem ahead of time without a SIM card, but WIN-911 will not function correctly until the SIM card is installed in the modem.

B. Installing a SIM Card Slot for SIM Card

Once you have your SIM card, you can install it into the modem.

NOTE: You can use a Micro or Nano SIM card but you'll need the appropriate Standard SIM card adapter. 

  • Locate the SIM card slot on the side of the modem. The slot is labeled SIM. 
  • Slide a SIM card into the SIM card slot with the contact side facing down as shown. When the SIM card is inserted fully, it will lock into place.
  • To remove the SIM card, push the card in and it'll eject from the device.

C. Modem Configuration

A web management interface is available for the configuration of the modem. You must connect to the modem via its Ethernet port to gain access via a web browser. The next section details the two options for connecting to the modem.

D. Connecting the Modem to a Network Switch / LAN

The Ethernet port on the modem does not support DHCP which means you'll need to manually configure a Static IP before attaching the modem to your existing LAN. We have found the easiest way to initially access and configure your modem is by connecting an Ethernet cable from the modem directly to a PC. You do not need to connect the modem to the PC you are running WIN-911 for this step, this is only needed for the initial configuration. Once the configuration is complete, you can connect the modem to your LAN.

The default Static IP address of the modem is You will likely need to change the IP address of your PC's network card to be within the same IP and subnet mask range as the modem to communicate with it. Since you need to change the Static IP address of the modem to a valid address on your LAN, you will need to work with your IT team to determine which Static IP address you can use. You may need to provide your IT team with the MAC address of the modem for them to create the IP reservation. You can find the MAC address labeled as NODE ID on the bottom of the modem. Once you have an IP address reserved for the modem, you can continue to the section below titled Changing the IP Address of the PC to change your PC's network card's settings to communicate with the modem.

E. Connecting the Modem Directly to a PC via Ethernet

If you plan to connect the modem directly to the PC for production use with WIN-911, you won't need to change the default Static IP address of the modem but you will still need to configure your PC's network card to be within the same IP and subnet mask range as the modem to be able to communicate with it. The next section, Changing the IP Address of the PC, will guide you through the process.

F. Changing the IP Address of the PC

  • Open Network Connections
    • The quickest way to get there is by typing ncpa.cpl in your Windows Start menu or from a Run prompt (Win Key + R).
    • Alternatively, navigate to Control Panel > Network and Internet > Network and Sharing Center > Click Change adapter settings on the left.
  • Locate the network adapter connected to your modem.
  • Right-click the adapter and select Properties
  • Select Internet Protocol Version 4 (TCP/IPv4) and click Properties
  • You will be changing the settings here so please take note of your current settings if you will need to restore them later. If you're planning on running WIN-911 with the modem connected directly to this PC, you won't need to change these settings back.
  • Change your settings to match the following screenshot

    NOTE: You will likely lose network/internet access once you apply these settings.

  • Click OK
  • Your PC should now be on the same subnet as the modem, and you'll be able to access the web configuration interface.
  • You can continue to the next section.

2. Accessing and Configuring the Web Management Interface

  • Open a web browser and enter the default address for the router:
    • Your browser will display a message stating There is a problem with the website's security certificate, you can safely ignore the warning and click Continue to this website. The web site forces HTTPS but the certificate it uses is a self-signed certificate which means it is not trusted by your PC.
  • You will be prompted for a Username and Password.
    • Default Username and Password is admin.
  • The First-Time Setup Wizard will appear
    • Select Network Router and click Next.

    • Enter a new password and click Next. In a later step, you will have the option of enabling security for Telnet sessions, if enabled, you will need these login details.

    • Enter the current Date, Time, and select your Time Zone.

    • Enter the Static IP/IPv4 Address and Mask you'd like to use and click Next.
      • If you'll be connecting the modem to your LAN, use the IP address and subnet mask your IT team provided.
      • If you'll be connecting the modem directly to the WIN-911 PC, you can leave the default address and mask.
      • You can leave IPv4 Primary DNS defaulted.

    • Uncheck Enabled for Cellular PPP Configuration and click Next.

    • Leave Cellular PPP Authentication Type set to None and click Finish.

    • Your settings will be saved but they won't take effect until you reboot the modem
    • DO NOT reboot yet, you will need to make a few more changes.

  • You should still have access to the Web Management Interface.
  • Select Setup > DHCP Configuration on the leftuncheck Enabled and click Submit on the bottom right.

    NOTE: The MTR modems can act as a router but WIN-911 does not use this functionality. If you do not disable DHCP before connecting the modem to your LAN, it is possible for the modem to begin assigning IP addresses to other devices on the network. Make sure DHCP is disabled before connecting to your LAN.

FIRMWARE 4.X and Earlier

Select to Cellular > Telnet Radio Access check the Enabled box.

FIRMWARE 5.X and Later

Please use this URL with your Modem IP address to gain access to the Telnet Radio Access configuration:

https://[Modem IP address]/cellular/telnetRadioAccess  (case-sensitive)

  • WIN-911 communicates with the modem through a Telnet session so we must enable it here.
  • You'll see an option for Login. When enabled (default setting), Telnet sessions will require that you log in with the same user credentials that are used to access the Web Management Interface. WIN-911 supports connections with or without the Login option enabled, but it is up to you to decide whether you want to disable it.
  • You'll also see an option for changing the default Port. If other applications running on the WIN-911 PC uses port 5000, you can change the port here to avoid a port conflict or for network security considerations.
  • Once you've made your changes, click Submit on the bottom right.

  • Select SMS > SMS Configuration on the left.
    • Here we are making sure this option is NOT enabled. WIN-911 will not function correctly if SMS is enabled.

  • You can now click on the left to reboot the modem.
    • If you changed the IP address of the modem so you can access it on the LAN, you'll need to change your Network Adapter settings back to its previous settings. You can now connect the modem to your LAN via a network switch. You may need to power cycle the modem after connecting the modem to your LAN if you cannot access it.
    • If you left the IP address the same and you're connecting the modem directly to the WIN-911 PC, you won't need to change the Network Adapter settings. 
  • Once the modem has rebooted, you'll be able to configure WIN-911 to use the modem.

3. Configure WIN-911 SMS Gateway

With your modem configured, you can set up WIN-911 to use the modem with the following steps.

  • Open the WIN-911 Workspace and navigate to Contacts > SMS > Gateway
  • Click the  button on the bottom left to add a new modem.
  • Name: Enter a unique name for the modem. 
    • You may find it useful to place the phone number of the modem in the name. E.g. Verizon LTE Modem (555-555-555)
  • Connection Type: Select
  • Address: Enter the IP address and port number of your modem. This is the IP address and port you configured in a previous step. 
  • Use Login: If Login is enabled for Telnet sessions, enter the User Name and Password. If you disabled Login when configuring the modem, disable it here as well.
  • Radio Type: WIN-911 automatically detects that you are using the MTR-LVW2/MTR-LAT1 so you do not need to specify a Radio Type. You can leave GSM selected.
  • Initialization: If you are using the MTR-LAT1 (AT&T), you can leave the initialization string blank.  Enter the following initialization string if you are using the MTR-LVW2 (Verizon):
  • Enable Incoming: When enabled, WIN-911 will process incoming SMS messages for the purpose of remote acknowledgment and Alarm / Report requests. If you do not require such functionality, feel free to disable this option.
  • Truncate messages to 70 characters: Both Verizon and AT&T allow multi-part text messages so you do not need to enable this option.
  • Click  to send a test message to a mobile phone. WIN-911 will also check the registration status, signal quality, and bit disparity rate of the modem. If the modem is not registered, you may need to call your cellular provider to make sure your SIM card is activated. If your signal is below 10, then you may have intermittent sending/receiving issues.
  • Select the  button to save your configuration.
  • WIN-911 is now configured to properly use your modem.
