Introduction
SMS Notification in TopView
TopView SMS Notification allows users to send and received text messages using a cellular modem.
Two methods are available in TopView for sending SMS messages with a cellular modem:
•SERIAL: requires a cellular modem connected to the TopView machine through a Serial or USB
port. Although the connection may be USB, the cellular modem communication is through a
COM port. For USB modems the modem driver will install a virtual COM port for serial
communication. Communication between TopView and the cellular modem occurs through AT
commands over the COM port.
•HTTP requires a MultiTech cellular modem that supports the MultiTech HTTP protocol. TopView
can communicate to the cellular modem over the network to send and receive text messages
using HTTP. There are no drivers to install on the TopView machine.

MultiTech rCell 100 Series cellular modems
For HTTP SMS support we are implementing the HTTP API provided by MultiTech in their rCell 100 Series
modems.
The rCell 100 Series modems support a wide range of cellular networks (GSM/CDMA) and countries.
Please see our modem information page for the latest information regarding supported modems.
https://www.exele.com/software-products/topview/resources/cellular-modems-sms/
In the US we are using the following models:
•Older models
oMTR-LAT1-B07 (AT&T/GSM, requires Mini SIM card)
oMTR-LVW2-B07 (Verizon, requires Mini SIM card)
•Newer models
oMTR-LNA7 (AT&T/GSM and Verizon, requires Micro SIM card)
▪GSM: supported in TopView 6.33 and later
▪Verizon:
•Outgoing: supported in TopView 6.33 and later
•Incoming (alarm acknowledge):
Not supported with firmware 5.1.x
Supported with firmware 5.2.1 and TopView 6.34
▪SIM Inserted Status: TopView can return the status of the SIM card
(inserted/not inserted) by querying the SIM card status from the modem.
“SIM inserted” status for the LNA7 currently returns “not inserted” even if the
SIM card is inserted in TopView 6.33 because the SIM status command used for
the older models is not available for the LNA7.
TopView 6.34 can return the correct status but multiple insert/removal of the
SIM may not be correctly recognized.
You will need to obtain a SIM card (correct size) from a cellular provider for use with the cellular
modem. Please check with MultiTech for the correct rCell 100 Series modem to support your cellular
carrier.

Configuration Overview
Note: this document will refer to the MultiTech rCell 100 Series modem as “cellular modem”
1. Configure the cellular modem for your network
2. Use a browser to connect to cellular modem web configuration tool
3. Make changes to the cellular modem settings to communicate with your network
4. Make changes to the cellular modem settings to enable the HTTP API
5. Test sending and receiving text messages
Insert SIM card into the cellular modem
With the modem power off, insert your SIM card into the cellular modem’s slot labeled SIM. Power on
the modem.
Warning: removing the SIM
If you remove and re-insert the SIM while the modem power is on, you should restart the modem.
Failure to restart the modem after a new SIM insertion may prevent the modem from successfully
sending and receiving SMS messages.
Warning: changing the SIM
If you change the SIM card with the same cellular provider (Verizon), or if you change providers, you
may need to reconfigure the modem before the new SIM will work.
More information on this issue is available from MultiTech
Configuring the cellular modem for your LAN network
The cellular modem has an Ethernet port labeled E-NET and a default IP address of 192.168.2.1
By default the cellular modem should operate as a DHCP Server upon first boot. We’ve seen various
behaviors depending on the model. For initial web configuration you can connect an Ethernet cable
between a computer and the cellular modem. If the computer is set automatically obtain its IP address
(DHCP) you should be able to see the cellular modem through a browser at its default IP address
192.168.2.1 (https://192.168.2.1)
If you cannot connect to the modem after a few minutes, configure your ethernet adapter with a static
IP address that can access 192.168.2.1. For example, you can set your ethernet IP address to
192.168.2.10
•From the command prompt type: ping 192.168.2.1
(newer firmware may not allow ping –try to connect using your web browser)
•Open a web browser and go to http://192.168.2.1 or https://192.168.2.1
* If you receive a security notice, ignore and continue

Web Configuration
Log into the device
Open your web browser and enter the address
http://192.168.2.1 or https://192.168.2.1
Firmware version 4.0 and above:
•Choose a username and password
Firmware Version 3.7 and below:
•Username: admin
•Password: admin
Making changes: restart required?
When you apply changes to the modem using the web configuration tool, some changes will require
that you restart the modem while others are applied without a restart prompt.
If you have configured modem settings yet are still having problems with the modem, we recommend
that you restart the modem to ensure that the most recent changes are loaded.
To restart the modem from the web configuration tool:
COMMANDS > RESTART DEVICE

First-Time Setup Wizard
A setup wizard will appear the first time you access the web configuration. Enter the following
responses to each question.
Note: some setup wizard screens may not appear or may appear differently based on the version of the
modem’s firmware.
•Mode: Network Router
•Choose password: enter the current password (admin) and a new password if you would like to
override the default password.
•Time configuration: Set your current time zone first, then the date and time if they are not
correct.
•Network interface: leave bridge as br0.
IPv4 address: most users will want to assign an IP address for their current network. Set the IPv4
address and Mask as required.
If DNS is also visible on this screen (older firmware), you should set the DNS to the IP address of
your DNS Server.
•Cellular Configuration/Cellular PPP Configuration: this setting allows the modem to use the
“data” portion of your cellular plan. This setting should not be required for SMS but may be
required if you want the modem to sync its time to a time server.
For our testing we uncheck “Enabled”. We recommend starting with this option
disabled/unchecked. See “Time Sync Options”for more information.
Note: some users have reported that they reduced SMS send failures by enabling PPP. Our
testing shows success with or without this setting enabled, but if you experience send failures
you may want to enable this setting (Web UI>Cellular>Cellular Configuration) or enabled it now.
•Cellular Authentication/PPP Authentication: most users will select NONE
•Remote Management: do not check “Enabled”
•Admin : most users will disable
•Access Configuration: this screen will appear in newer firmware versions.
For “HTTP Redirect to HTTPS” check :Enabled”, “check: via LAN”
Newer firmware (v5 and later) requires use of HTTPS so we recommend that all users configure
the modem for HTTPS only to reduce issues with future firmware upgrades
•Bootloader Protection: this screen will appear in newer firmware versions.
Authentication Status should be disabled. Most users should not enter a password for the
bootloader.
Click [Finish]
DO NOT RESTART THE DEVICE YET.

Remove DHCP setting
Most users have an existing DHCP Server on their network and will not want to use the DHCP Server in
the cellular modem if it is enabled. Depending on your firmware version, the cellular modem may be
configured to act as a DHCP Server. With newer firmware DHCP will already be disabled.
SETUP > DHCP Configuration
Newer firmware should show “Disabled” for the status of the interface of your local IP address (IPV4).
If DHCP is enabled (IPV4), edit the DHCP setting using the pencil icon if it is visible.
•Uncheck “Enabled”
•Click [Submit]
If DHCPv6 and Router Advertisement is enabled you should be able to leave this enabled.
SIM Pin
If your SIM card requires a pin number
CELLULAR > Cellular Configuration
Under Modem Configuration enter the SIM Pin.
Restart the device
SAVE AND RESTART > then click [OK] to restart the cellular modem
Move Ethernet cable from computer to network switch
You can now unplug the Ethernet cable from your computer and attach it to your network (e.g. a
switch). Once the cellular modem is connected to your network and has restarted you can log back into
the web configuration using
http://ipaddress or https://ipaddress
where ipaddress is the new IP address assigned in the setup wizard. Remember to use the new admin
password that you assigned in setup wizard.
Upgrade firmware to version 5.2.1
In order to ensure compatibly between TopView and the modem, we recommend upgrading only to the
versions stated in this document. If your modem is at least this version, you can skip this step.
ADMINISTRATION > FIRWARE UPGRADE
To download newer firmware
•Click on your cellular modem model on the MultiTech rCell 100 Series page
•Click DOWNLOADS

Time Sync Options
It is important for the modem to have the correct time.
You have two options for ensuring that the modem has the correct time.
1. Allow the TopView machine to set the time of the modem
2. Allow the modem to sync its time with a time server (may require Cellular Configuration
enabled)
Once you select an option, the other option should be disabled.
Allow TopView to set the time of the modem
In TopView 6.34 and later, TopView can set the time of the modem when it sends SMS messages and
polls for incoming messages.
This option requires that SSH is enabled on the modem. To check this setting, go to
ADMINISTRATION > ACCESS CONFIGURATION (Set to enabled, port 22, via LAN).
To enable this option in TopView:
Launch the TopView Configurator, select Global Options>Notification.
To test the ability of TopView to sync the time of the modem (v6.34 and later):
Launch the TopView Configurator and open your configuration file
Left menu: Email-SMS Notification > [Configure]
Outgoing SMS Setting screen
Click [Test modem] to verify connection to the modem. The current time of the modem is displayed.
Click [Sync time]
Allow the modem to sync to a time server
This option may require you to enable “Cellular configuration” on the modem which enables use of the
“data” portion of your cellular plan.
To enable this option in the modem:
SETUP > TIME CONFIGURATION
SNTP: check “Enabled”
Set the polling time to 5 minutes until you can verify that the time sync (SNTP) is working correctly
(below).
To check the status of the modem time sync (SNTP):
STATUS & LOGS > SERVICES
Verify that the SNTP service status is successful. If this is failing, you may need to enable “Cellular
configuration” on the modem (CELLULAR > CELLULAR CONFIGURATION). If SNTP continues to fail you
should disable SNTP and allow TopView to set the time of the modem.

Verify a few items…
Cellular signal
•HOME >
The Device Information screen gives an overview of the cellular modem state.
Verify that you have a cellular signal:
There are a few default settings that must be correct before you can enable SMS. Please verify the
following settings are correct:
Cellular > Wake Up On Call
•Verify that “Wake up on call” is not checked
Enabling SMS (below) will not be possible with this option checked
DNS:
Ensure you have the proper DNS address set for your LAN.
You should have one of the following options depending on your firmware:
SETUP > IP CONFIGURATION > DNS
or
SETUP > GLOBAL DNS
•Enable Forwarding Server
•Primary Server: enter the IP address of your DNS
•Submit
SETUP > TIME CONFIGURATION
•Current: verify that the current date/time/zone are set correctly
•SNTP: enabled or disabled based on your selected option in “Time Sync Options”
•Submit

Enable SMS
SMS > SMS Configuration
•Check “Enabled”
•Send and Receive SMS to Keep: 1000
•Resend Failed SMS: 5
* When TopView sends an SMS message to the cellular modem it is placed into a queue on the
cellular modem. TopView does not wait for the message to complete sending.
Enter a value for “Resend Failed” if you would like the cellular modem to retry failures.
•Click [Submit] to save these settings
Verify connection to your cellular carrier
CELLULAR > RADIO STATUS
The radio status will display connection information for the connected cellular service.
Expected information:
•Home Network: Cellular service provider
•RSSI: Received Signal Strength Indication
•Service: Cellular service connection type
•MDN (Phone Number): Mobile Directory Number. In some SIM/carriers, the value may not be
present and therefore not displayed
If you are not connected to the cellular service, you can try to reset the cellular connection
ADMINISTRATION > DEBUG > RESET
SAVE AND RESTART > then click [OK] to restart the cellular modem
Send a test SMS message
SMS > Send SMS
•Enter a recipient phone number and click [Add]
•Enter a Message
•Click [Send]
SMS > Sent
You should see your test message listed. After a successful send the Status should change to
“sent”. You may need to refresh your browser to see the changed status value.

HTTP or HTTPS?
TopView can send HTTP or HTTPS commands to the cellular modem.
We recommend using HTTPS. Newer versions of the modem firmware (5.0 and later) have removed the
“enable HTTP” settings available in earlier versions of the firmware. If you are using an earlier version of
the firmware that allows HTTP, upgrading to later versions may persist “enable HTTP” while also
removing your ability to change this setting. Therefore we recommend all users configure the modem
for HTTPS access only.
HTTP
Note: we recommend using HTTPS instead of HTTP. Some of the HTTP settings in this section are only
available in earlier versions of the firmware and are removed in later firmware versions.
If you are using a version of the firmware that supports HTTP (before v5) and still desire to use HTTP
instead of HTTPS:
ADMINISTRATION > ACCESS CONFIGURATION
•Check “HTTP…Enabled if not already checked (not available in v5 firmware)
•Uncheck “HTTP…Redirect to HTTPS
•Click [Submit] to save changes
SAVE AND RESTART > then click [OK] to restart the cellular modem

HTTPS
Use of HTTPS requires the creation of a certificate on the cellular modem and installation of the
certificate on the TopView machine.
IP Address or DNS/host name for the certificate?
The certificate will be created for the modem’s IP address or DNS name.
Most users will access the modem by it’s assigned static IP address and will create the certificate for the
modem using the IP address. If you or your IT group created a DNS name for the modem’s IP address
and are required to use this name, you should create the certificate using the DNS name and not the IP
address. This is specified in the “Common name” field below.
*If you create the certificate for the DNS name you must use this name, and not the IP address, when
configuring access to the modem from TopView.
Log on to web configuration using HTTPS
Log on to the cellular modem web configuration using HTTPS
https://ipaddress
where ipaddress in the IP address of the cellular modem
Create the certificate
ADMINISTRATION > CERTIFICATE MANAGEMENT

Diagnosing incoming SMS issues - Verizon
Model MTR-LVW2 (older model)
With firmware 5.1.x and earlier, this modem requires a SIM that allows storage of SMS messages on the
SIM card. See our TopView SMS modem information page for required SIM SKUs and how you can
obtain a compatible SIM.
With firmware 5.2 and later you should not need to use specific SIM cards with this modem.
Model MTR-LNA7 (newer model)
With firmware 5.1.x and earlier, this modem cannot receive incoming messages.
With firmware 5.2.1 and later you should be able to receive incoming SMS messages if you are using
TopView 6.34 or later.
Set SMS Format to “Verizon”
To receive incoming messages, you need to ensure that the modem’s LTE SMS Format is set to
“Verizon”. From the TopView Configurator, Email-SMS Settings, Outgoing SMS Settings:
•Click [Test modem]
•If the displayed LTE SMS Format is not “Verizon”
oClick “Check and enable SMS format (MTR-LNA7)”
oSet the SMS format to “Verizon” and click “Apply”. Read the setting to verify.
Return to the modem’s web configuration and check SMS > RECEVIED. If this resolved the issue, you
need to set the global option as explained in the next section.
Set Global Option to verify SMS Format = Verizon
If you changed the SMS format to “Verizon” to resolve the issue, this format will only persist until the
modem is restarted. Therefore, you need to instruct the TopView Engine to check and reset the format.
From the TopView Configurator:
Global Options > Notification > Set SMS format of modem to [Verizon]

Create separate user accounts
Note: Firmware version 4.0.5 and later only
We recommend creating a separate user account on the modem for each TopView Engine/configuration
that sends/receives SMS messages through the modem.
•Log into the cellular modem at http://ipaddress or https://ipaddress where ipaddress is the IP
address of the modem
•On the side panel select [Administration] -> [User Accounts]
•Click [Add New User]
•Choose a username and in the [Role] dropdown select administrator. The other fields are
optional
•Click [Submit] then choose a password

HTTPS on Windows 7 SP1, Server 2008 R2SP1, Server 2012
Use of HTTPS with this modem and TopView requires a version of TLS (Transport Layer Security) that
may not be currently enabled in Windows 7 SP1, Server 2008 R2 SP1, and Server 2012.
Symptom
•You have configured your modem with HTTPS as specified in this document
•When you try to send a test message from TopView you receive the following error
"The underlying connection was closed: An unexpected error occurred on a send."
