SAFETY WARNINGS
Chapter 2 – Safety Warnings
Radio Frequency (RF) Safety
Due to the possibility of radio frequency (RF) interference, it is important that you follow any special regulations
regarding the use of radio equipment. Follow the safety advice given below.
Operating your device close to other electronic equipment may cause interference if the equipment is
inadequately protected. Observe any warning signs and manufacturers’ recommendations.
Different industries and businesses restrict the use of cellular devices. Respect restrictions on the use of
radio equipment in fuel depots, chemical plants, or where blasting operations are in process. Follow
restrictions for any environment where you operate the device.
Do not place the antenna outdoors.
Switch OFF your wireless device when in an aircraft. Using portable electronic devices in an aircraft may
endanger aircraft operation, disrupt the cellular network, and is illegal. Failing to observe this restriction
may lead to suspension or denial of cellular services to the offender, legal action, or both.
Switch OFF your wireless device when around gasoline or diesel-fuel pumps and before filling your vehicle
with fuel.
Switch OFF your wireless device in hospitals and any other place where medical equipment may be in use.
Interference with Pacemakers and Other Medical Devices
Potential interference
Radio frequency energy (RF) from cellular devices can interact with some electronic devices. This is
electromagnetic interference (EMI). The FDA helped develop a detailed test method to measure EMI of implanted
cardiac pacemakers and defibrillators from cellular devices. This test method is part of the Association for the
Advancement of Medical Instrumentation (AAMI) standard. This standard allows manufacturers to ensure that
cardiac pacemakers and defibrillators are safe from cellular device EMI.
The FDA continues to monitor cellular devices for interactions with other medical devices. If harmful interference
occurs, the FDA will assess the interference and work to resolve the problem.
Precautions for pacemaker wearers
If EMI occurs, it could affect a pacemaker in one of three ways:
Stop the pacemaker from delivering the stimulating pulses that regulate the heart's rhythm.
Cause the pacemaker to deliver the pulses irregularly.
Cause the pacemaker to ignore the heart's own rhythm and deliver pulses at a fixed rate.
Based on current research, cellular devices do not pose a significant health problem for most pacemaker wearers.
However, people with pacemakers may want to take simple precautions to be sure that their device doesn't cause
a problem.
Keep the device on the opposite side of the body from the pacemaker to add extra distance between the
pacemaker and the device.
Avoid placing a turned-on device next to the pacemaker (for example, don’t carry the device in a shirt or
jacket pocket directly over the pacemaker).

SAFETY WARNINGS
Antenna
The antenna intended for use with this unit meets the requirements for mobile operating configurations and for
fixed mounted operations, as defined in 2.1091 and 1.1307 of the FCC rules for satisfying RF exposure compliance.
If an alternate antenna is used, consult user documentation for required antenna specifications.

INSTALLING AND USING THE DEVICE
Chapter 3 – Installing and Using the Device
Installing the Device
1. Connect suitable antenna(s) to the antenna connector(s).
2. If your device is the serial version:
Connect the DE9 male connector (9-pin) of the RS-232 cable to the RS-232 connector on the device, then
connect the other end to the serial port on the other desired device.
Screw-on the power lead from the power supply module into the power connection on the device.
Plug the power supply into your power source.
3. If your device is the USB version:
For information about the USB cable that helps power your device, see the section "USB Cable
Recommendations."
The USB cable uses power from the USB power line. Connect one end of the USB cable to your computer
or other USB high power device, such as a hub.
Connect the other end to the device's USB connector.
4. The POWER LED lights after the device powers up.
Placing Serial Devices in Power Save Mode
The serial devices offer a low power mode (sleep or power save mode) using the power save switch (below the
SIM card slot) on the device to change from normal or low power mode. The low power mode is intended for
battery or solar-powered, IoT applications such as outdoor remote sensors.
There are other techniques to place the device into low power mode. This example uses data terminal ready (DTR)
and the AT command +CFUN=5. For other techniques, review the AT command guide for your device, as described
in the Documentation section of this guide.
The device also wakes up from sleep mode by using the wake-on-ring feature. See the following example using the
ring indicator line to wake the host processor when the radio receives an incoming call or SMS message. Your
application then needs to act on the ring indication and wake up the device by asserting DTR.
Using Low Power Mode
Here are some different configuration options for low power mode:
To turn on low power mode, set the power-save switch to LOW.
On the RS-232 interface, ensure your application controls DTR and makes it active (on). To configure the
device for DTR control, issue either AT&D1 or AT&D2 for DTR control. The &D0 command does not allow
low power to operate.
To configure the device to enter low power (sleep) mode, issue AT+CFUN=5 to the radio.
To configure the device to wake from low power mode by using the wake-on-ring feature, issue
AT#E2SMSRI=1000. This configures the ring indicator to go active for 1000 ms when an SMS message is
received.
To have the device enter sleep mode, set DTR to inactive (off) on the RS-232 interface. The clear to send
(CTS) signal is off when the device is in sleep mode.
18 MultiConnect®Cell MTC-LAT1 User Guide
Page 19
INSTALLING AND USING THE DEVICE
USB Cable Recommendations
If your device has a USB connector, to avoid enumeration or power issues:
Use a high-speed USB cable that is as short as possible.
Use a well-shielded cable with at least 24 AWG wire pair for power/ground and 28 AWG wire pair for data
lines.
If possible, use a USB port that connects directly to the motherboard rather than a USB port with added
cabling inside the computer chassis.
Use USB 3.0 ports if available. These ports are typically rated for more current.
You can order the USB cable through MultiTech. The part number is CA-USB-A-MINI-B-3
Powering Down Your Device
CAUTION: Failing to properly power down the device before removing power may corrupt your device's file
system.
To properly power down your device, use the following sequence :
1. Issue the AT#SHDN command.
2. Wait 30 seconds.
3. Power off or disconnect power.
Note: If you send AT#SHDN and do not remove power, the radio restarts after 60 seconds.
Installing a SIM Card
This model requires a SIM card, which is supplied by your service provider. To install the SIM card:
1. Locate the SIM card slot on the side of the modem. The slot is labeled SIM.
2. Slide the SIM card into the SIM card slot with the contact side facing down as shown. When the SIM card
is installed, it locks into place.
MultiConnect®Cell MTC-LAT1 User Guide 19
Page 20
INSTALLING AND USING THE DEVICE
Removing a SIM Card
To remove the SIM card, push the SIM card in. The device ejects the SIM card.
Mounting Device to Flat Surface
1. Locate the groove on the bottom of the device.
2. Slide the mounting bracket through the groove.
3. To secure the bracket to the desired surface, place and tighten two screws in the holes on either end of
the mounting bracket. The dimensions illustration in this guide shows the mounting bracket, as well as
the dimensions for placement of the screws.
LTE Antenna Diversity
Antenna diversity uses two receive antennas to improve the downlink connection (cell tower to mobile). It has no
effect on the uplink (mobile to cell tower).
Antenna diversity is useful in environments where the signal arrives at the device after bouncing off or around
buildings or other objects. The bounced signal may be attenuated by going through semi-transparent (to the
signal) objects. Each signal alteration can change its magnitude, phase, orientation, or polarization. This complex
environment can exist in cities, inside buildings or in traffic. In this environment, signal paths from the cell tower
form an interference pattern of peaks and nulls. These peaks and nulls can be very close together.
Antenna diversity provides an advantage in complex environments because if one receive antenna has a poor
signal due to an interference null pattern, the other antenna is likely not in the null and has better reception. The
radio compares the reception from both receive antennas and uses the one with the strongest signal.
Important: You must deploy with two antennas, unless your carrier has authorized you to deploy with one
antenna.
Selecting Antennas
Select an antenna based on your product and application. Typically, both antennas are the same and either can be
the main receive antenna.
Placing External Antennas
Antennas are usually a quarter wavelength apart from each other. With multiband radios where the quarter
wavelengths in each band are diverse from each other, this rule may not be practical. Choose spacing based on the
band used most often or the band with connection difficulty. Some environments are harsher on particular bands.
MultiTech products have antenna connectors at the best spacing for the product size.
Placing antennas in close proximity to each other is not optimal, but you can do it if necessary. It depends on the
signal strength to and from each antenna.
If the antennas are too close together for your application, use a similar antenna on a short cable for the second
receive only antenna.
Placing GPS Antennas
GPS antennas need a clear view of the sky. Position the GPS antenna so the diversity antennas do not block its
view of the sky.
20 MultiConnect®Cell MTC-LAT1 User Guide
Page 21
Antenna Approvals and Safety Considerations
Note the following:
Carriers conduct antenna diversity tests.
There are no EMC concerns about antenna diversity.
All antennas need to have a minimum flammability rating.
Safety requirements depend on your final product.
Unless otherwise noted, antennas certified by MultiTech are not approved for outdoor use. Do not extend
these antennas outside of any building.
Diversity and Power Draw
There are no significant power draw differences.

CONFIGURING AND COMMUNICATING WITH YOUR DEVICE
Chapter 5 – Configuring and Communicating with
Your Device
Interacting with Your Device Overview
This section describes how to use AT commands to interact with your device. Using terminal software such as
Kermit, you can issue AT commands to communicate with and configure your modem. The AT commands let you
establish, read and modify device parameters and help you control how the device operates. This section
documents basic interactions with your device, such as verifying signal strength and network registrations, sending
and reading SMS text messages, and sending and receiving data.
Generally, USB modems are used as unintelligent bit pipes. In Windows, this means you create a dial-up network
connection that uses the Windows IP stack to use the modem to create a PPP connection to the cellular network.
The modem is assigned an IP address from the cellular carrier. This connection provides Internet access and is the
basis for TCP/IP communication for sending and receiving email, creating TCP/UDP Sockets, or putting and getting
files from an FTP server.
In Linux, PPPD is used to dial the modem and create the connection to the cellular TCP/IP network. This provides
Internet access for sending and receiving email, creating TCP/UDP Sockets, or putting and getting files from an FTP
server.
Before Using the Device
Before using the device:
Install any drivers. Refer to the separate driver installation guide for your device.
Power up your device and ensure it is connected to your computer that issues AT commands.
Note: Wait 10 seconds after power-up before issuing any AT commands.
Install terminal software that can communicate with the device, such as HyperTerminal, Tera Term, Kermit,
or Putty.
Using Command Mode and Online Data Mode
Modems have two operation modes, command and online data. After power up, the modem is in command mode
and ready to accept AT commands.
Use AT commands to communicate with and configure your modem. These commands establish, read, and modify
device parameters and control how the modem works. The device also generates responses to AT commands that
help determine the modem’s current state.
If the modem is in online data mode, it only accepts the Escape command (+++).
To send the modem AT Commands from terminal emulation software, set the software to match the modem’s
default data format, which is:
Speed: 115,200 bps
Data bits: 8
Parity: none
24 MultiConnect®Cell MTC-LAT1 User Guide
Page 25
Stop bit: 1
Flow control: hardware
To confirm communication with the device:
Type AT and press Enter.
If the device responds with OK, it is properly communicating.
