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.
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.
Digitus USB Serial Converter
Connect the DB9 male connector (9-pin) of the RS-232 cable to the RS-232 connector on the modem, then connect the other end to the serial port on the Digitus USB Serial Converter.

Direct Serial (RS-232) Connection
- If your computer is equipped with a Serial COM port, simply connect the DB9 male connector (9-pin) of the RS-232 cable to the RS-232 connector on the modem, then connect the other end to the serial port on your computer.
- Screw-on the power lead from the power supply adapter into the power connection on the modem.
- You do not need to install a driver to use the modem.
Activating the Modem
Locate Modem COM Port
In order for WIN-911 to use your modem, you must tell it which COM port the modem was assigned to. If you're using the Digitus USB Serial Converter, then your COM port is the port assigned to the USB Serial Port under Ports (COM & LPT). If you're using a serial port on your computer then you'll need to open Device Manager and look under Ports (COM & LPT) for a Communications Port. Typically you'll have two Communications Ports, one on COM1 and the other on COM2.
- You'll need to make a connection to the modem with a terminal program such as PuTTY, TeraTerm, or HyperTerminal using the COM port you found in the previous step. We'll use PuTTY in this guide which you can download from here, PuTTY Download.
- Open PuTTY and select the Serial radio button. Enter the COM port your modem is assigned to in the Serial line field and enter 115200 for the Speed. Select Open to connect to the modem.
- You should now be connected to the modem and looking at a terminal window. Enter ATE1 and hit enter. You should receive an OK response.
- You need to verify you have a strong enough signal to activate the modem. You can do this by typing the command AT+CSQ. You will receive a response similar to +CSQ: 15,99. The first value of the response indicates the signal strength [0 - 31]. You will need a signal of 10 or more. If your signal is below 10, activation may fail.
- Enter the following command to activate the modem, AT+CDV*22899; (be sure to include the semicolon). Wait for the following responses to come through...
- Once you receive NO CARRIER, power cycle the modem by unplugging the USB cable from the modem and plugging it back in.
- Reconnect to the modem via PuTTY (step 2).
- You can check to see if the registration was successful with the following command, AT+CREG? You will receive a response similar to +CREG: 0,1. You want the second value to be either a 1 or 5 which indicates registration was successful.
- Close PuTTY.

- Radio Type: The MTC-C2 uses a CDMA radio so you'll need to select
- Initialization: The Multi-Tech modems do not require an additional initialization string so leave this field empty.
- 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.
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.
- Select the button to save your configuration.
- WIN-911 is now configured to use your modem!
If you have followed these steps correctly, you have installed and setup your cellular modem for use with WIN-911.
