Introduction

WIN-911 introduces the ability to configure several modems on a single system. WIN-911 can then use these modems to send messages at a faster rate as well as have them serve as backups of one another. For example, if two modems are configured, the WIN-911 SMS module will use both modems simultaneously to send alarm messages. If one modem fails to send an alarm, the WIN-911 SMS module would redirect the alarm to the other modem.


Getting Started

You will need to setup a wireless account with Verizon and activate the modem before you can begin using it. If you have not provided Verizon with the MEID from the back of your modem, activation will fail. WIN-911 will only use the SMS functionality of your modem so you do not need a voice or a data plan. We recommend using an unlimited texting plan.



SMS Gateway using Telnet

 

Before configuring, using a command prompt, obtain the IPv4 address you are currently using by typing “ipconfig.” Take a screenshot of that information, as you will need it later in the configuration.

 


 

First, you need to configure your router by using your router’s web management Interface. You might need to change the IP address of your computer to be in the same IP and subnet mask range as the device.

 

To do so, open your Control Panel>Network and Sharing Center>Change adapter settings. Right-click on your Local Area Connection and click Properties.

 

Click on Internet Protocol Version 4 (TCP/IPv4), then click Properties.

 


 

Make sure you document your current settings, as you will need to set them back once the modem is configured to your current subnet. Select the Use the following IP address radio button and change the IP address to 192.168.2.2 and the Subnet Mask to 255.255.255.0.

 



Once those changes are made, your machine will now be available on the same subnet and you will be able to access your modem's web management interface from a web browser. Open an Internet browser. In the browser's address field, type the default address for the router: http://192.168.2.1.

 

 

A login page opens. In the username field, type the default user name: admin (all lowercase). In the password field, type the default password: admin (all lower-case). The password can later be changed if you decide to add security to your modem. More information on this is listed later in this document.

 

 

After you have logged in, in the left explorer pane under "Setup," you can change the IP address of the modem to that of your original sub-net. Make sure you define an original sub-net address that is not already being used by another machine on your network. Consult your IT department for a list of unoccupied sub-net addresses.

 


 

Under Setup, select the "DHCP Configuration" and disable by un-checking the "Enabled" box.

 


 

Still under Setup, select "Serial-IP Configuration" and check the box "Enabled." This will enable WIN-911 to use the settings defined within the modem.


 



Navigate to "Cellular," and under "Telnet Radio Access," check the "Enabled" box 

 

Optional: To enable security on this modem, under Cellular, select Telnet Radio Access, and check the "Login" box.

*** Versions earlier than WIN-911 3.16.20 do not support the Login option. ***

 


 

If you want to change the password for accessing the modem's web management interface, on the left explorer pane, under "Administration," select "Access Configuration," then click the "Change Password" icon.




On the explorer pane, select "SMS," and edit the "SMS Configuration" by un-checking the "Enabled" box




With your new setting changes, click Save and Restart, and restart the modem.

 

With your modem now available on your original subnet, you can revert back to your original IP settings, then test to see if it changed by browsing with the newly acquired IP of the modem.

 

Once you have confirmed that the connection was successful, you can then configure WIN-911.







Setting Up WIN-911



  1. Open the WIN-911 GUI and go to Contact > SMS > Gateway.

  2. Click the  button on the bottom left to add a new modem.

  3. Name: Enter a unique name for this modem.

  4. Connection Type: Select for ethernet modem
  5. Address: Enter the IP address you configured under Basic Setup on the modem settings portal. To the right, enter the port number you configured for Telnet Radio Access (5000 by default).
  6. If security is enabled for the modem (under Telnet Radio Access), provide your login credentials below; otherwise uncheck the box to configure WIN-911 to not attempt login.

     

  7. Radio Type: The MTR-C2 uses a CDMA radio so you'll need to select 

     

  8. Initialization: The Multi-Tech modems do not require an additional initialization string so leave this field empty.

  9. If you'd like WIN-911 to respond to incoming text messages for alarm requests, alarm acknowledgements, and Report requests then leave the Enable Incoming box checked. If you would like WIN-911 to ignore incoming messages, uncheck the box.

  10. Use the  button to send a text message to yourself. WIN-911 will also check the registration status, signal quality, and bit disparity rate. If the modem is not registered, you will need to call your cellular provider to make sure your modem is activated. If your signal is below 10, then you may have intermittent sending/receiving issues.

  11. Select the  button to save your configuration.

  12. WIN-911 is now configured to use your modem!


Troubleshooting

 

If you are having trouble sending a successful test message, first run through the settings to make sure they are all correct.


Confirm that you can make a connection using PuTTY, a telnet client is available through the link below:

http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html


In the PuTTY configuration, select the "Telnet" radio button


Enter the IP address of the modem you are trying to connect to, and change the port field to "5000"



Once you click "Open" a blank black box will open




Before we begin, remember that PuTTY does not accept deletion, so, if you make a mistake and have to delete and re-type, you will receive an error. Hit Enter, accept the error and re-attempt the command.


First, start off by entering ATE1 and hitting enter. Initially you may not see anything, but this command will enable echo so that you will be able to see the commands entered. Once echo is enabled, use the below commands one at a time too initialize the modem.


AT+CMGF=1 <ENTER>


AT+CMGD=1,4  <ENTER>


AT+CNMI=2,1 <ENTER>


Once the modem has the correct initialization commands, you can use the command AT+CMGS="xxxxxxxxxx" to send a text message to a cell phone.  


"xxxxxxxxxx"  represents the fully qualified phone number.  The fully qualified phone number contains the country code + cellphone number.  In some locations a prefix is required before the country code.  If the send message fails try using one of these prefixes:


AT+CMGS="+ <country code><phone number>"

AT+CMGS="00 <country code><phone number>"



After you enter the AT+CMGS command, a ">" will appear.   Enter the text message you want to send, and hit CTRL+Z to send. A successful send will result in +CMGS: ###  then OK.


Below is an example of the entire sequence above, where echo is enabled, the modem is initialized, and text message was sent out successfully. 





Conclusion

If you have followed these steps correctly, you have installed and setup your cellular modem for use with WIN-911.
