1. Multi-Tech MTC-LNA4 Install Guide
This guide will walk through the installation and setup of the Multi-Tech's MTC-LNA4 using a serial cable with an RS-232 to USB converter. We DO NOT recommend using the USB version of the LNA4.
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 and obtain a Standard SIM card.
The MTC-LNA4 supports both AT&T and Verizon. By default, the modem is configured for use with AT&T. If you'd like to use Verizon, you will need to manually change the modem configuration for use with Verizon. You will find more information below.
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.
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 Hardware
D. Modem Configuration
After you have connected the modem to your PC using the Serial to USB adapter, you will need to identify the COM port that it has been assigned.
- Open Device Manager
- Expand the Ports (COM & LPT) section
- You should see USB Serial Port (COMX), where X is the COM port it was assigned
In this example, the modem was assigned COM3
If you are using an AT&T SIM card, you won't need to configure the modem. Skip ahead to the Configure WIN-911 SMS Gateway section.
If you are using a Verizon SIM card, you'll need to connect to the modem using a terminal program so that you can switch the modem to operate on Verizon's network. We recommend using PuTTY, which can be downloaded from here.
- Download and run PuTTY
- When PuTTY appears, select Serial for Connection type
- Enter the COM port your modem has been assigned in the Serial line field
- Change Speed to 115200
- Click Open and a terminal window will appear
2. Configure WIN-911 Configurator
With your modem configured, you can set up WIN-911 to use the modem with the following steps.
- Open the WIN-911 Configurator and open Global > SMS
- If you have previously changed settings here, click the Reset Defaults button
- Change Port to the COM port the modem is assigned to
- Make sure Network Type is set to GSM
- Click OK and save your configuration
- Make sure you have an SMS Connection defined in the Phone Book and then start Scan and Alarm
- In the Alarm Monitor window, click Manual Message
- Select the SMS Connection you created and type a test message to send
- Click the Send button
- If the message was successfully sent, WIN-911 is now configured to properly use your modem.
