Section 1 - Product Overview
Introduction
D-Link’s DWM-311 4G LTE M2M Modem is a robust 4G LTE modem that provides blazing fast connection speeds for
embedded Machine-to-Machine (M2M) applications. The single mode LTE modem provides an economical and reliable
high-speed connection suitable for the most demanding Internet of Things (IoT) applications. This cost-eective device is
pre-congured to provide a complete connectivity solution out of the box.
The industrial-grade casing means the DWM-311 provides reliable high-speed connectivity in extreme conditions. The
corrosion-resistant zinc-plated steel case and wide operating temperature and humidity tolerance mean that the DWM-311
is ready for the most demanding M2M applications in virtually any environment. Wall mounts and exible interfaces allow
the DWM-311 to be mounted virtually anywhere for optimal connectivity.
The DWM-311’s USB and Ethernet interfaces allow connectivity to be added to virtually any device. Ethernet means
driverless, instant access for any Ethernet-enabled device, without the need for pre-conguration or special software.
Standard USB protocols allow you to add high-speed Internet access to devices not traditionally equipped with network
adapters. Ethernet makes the DWM-311 a true plug-and-play solution, suitable for mass deployment or small scale use.
Should unique settings be required, the easy-to-use web interface can be congured through any web browser.

Section 2 - Installation
Before You Begin
Installation
This section will guide you through the installation process. Placement of the router is very important. Do not place the router in an enclosed area
such as a closet, cabinet, or in an attic or garage.
Observe the following precautions to help prevent shutdowns, equipment failures, and personal injury:
• Install the DWM-311 in a cool and dry place. Refer to the technical specications in the user manual for the acceptable operating temperature
and humidity ranges.
• Install the modem in a site free from strong electromagnetic sources, vibration, dust, excessive moisture, and direct sunlight.
• Place antennas in an unobstructed area with clear LTE signal. Avoid metal boxes, brick walls, and other dense materials. Use the web interface
to conrm signal strength before permanent installation.
• Visually inspect the power connector and make sure that it is fully secure.
• Do not stack any devices on top of the modem.
Attach the External Antennas
The DWM-311 requires two external antennas to function correctly. The included antennas are interchangeable, but third party antennas may
require connection to specic ports.
1. Attach the antennas to the included magnetic mounts. Turn the hex nut clockwise to fasten the antenna.
2. Place antennas where they will receive optimal signal. Arrange them so they point upward.

Section 2 - Installation
Powering the Modem
The modem can be powered either directly via mini-USB or via Power over Ethernet (PoE) using a PoE splitter.
Using included Mini-USB cable
Use the included mini-USB AC adaptor to power the modem. Attach the USB connector to the included AC adaptor. Attach the AC adaptor to a wall
socket. Insert the mini-USB connector into the port on the modem labelled with the symbol.The power LED will turn green to indicate the modem
is receiving power.
Using Power over Ethernet (PoE)
The DWM-311 can be powered via Power over Ethernet (PoE) (sold separately) by connecting a 5.5 mm DC to mini-USB adaptor (sold separately)
to a PoE splitter. This may be useful when long cable lengths required. Standard PoE has a range of up to 330 ft (100 m). The following steps outline
setting up the modem with a PoE Splitter/Injector kit.
1. Verify your PoE splitter is set to output 5 volts.
Warning: Higher voltages may damage the DWM-311.
2. Attach the PoE splitter’s DC-OUT to the DWM-311’s mini-USB power input using the DC-to-Mini-USB adaptor (sold separately). The power input
is labelled with the symbol.
3. Once the antennas are placed, attach both antenna cables to the DWM-311’s external SMA connectors, labelled DIV and PRI. Turn the hexnut
clockwise to secure the cables.
Note: The included antennas are interchangeable. Third party antennas may require connection to specic ports.

8D-Link DWM-311 User Manual
Section 2 - Installation
3. Attach the PoE splitter’s LAN OUT to the DWM-311’s DATA1 port on the DWM-311.
4. Finally, connect the PoE injector’s LAN-IN port to an available Ethernet port on
your end device and plug in the injector’s power cord into a power outlet as
shown in the diagram.
Note: the above case assumes you are using a D-Link DPE-301GI 1-Port Gigabit PoE
Injector and D-Link DPS-301GS 1-Port Gigabit 30W PoE Splitter (sold separately).
Other PoE congurations may vary.
Connecting Devices
After the DWM-311 has been successfully installed, the modem can be connected
to the end device via either of the following connection methods:
Over Ethernet
The Ethernet port can be connected to an end device. Use a standard Category 5/5e/6
RJ-45 Ethernet cable to connect the end device to the modem. The port will auto-
negotiate to the highest possible port speed based on the connected device. Note
that the DWM-311 supports a maximum transfer speed over Ethernet of 100 Mbps.
Over USB 2.0
To connect the modem over USB, connect a micro-USB cable (not included) to the
port marked DATA2 on the back panel. Insert the other end of the cable into a free
USB port of the device you wish to connect.
Note: The modem cannot accept power over micro-USB, only over mini-USB through
the port labelled with the symbol.
Connect DATA1 on the
DWM-311 to the Ethernet
port labelled PoE OUT on the
PoE injector. Connect the
Mini-USB port to the
splitter’s DCOUT using an

Conguration
To access the conguration utility, open a web browser such as Internet Explorer
and enter the address of the router (192.168.17.1 by default for connections over
Ethernet, and 192.168.15.1 for connections over micro-USB).
To login to the conguration utility, admin is the default username and the default
password is printed on the label on the back of the modem.The Reset button causes
the password eld to be reset to blank.
Note: If you get a Page Cannot be Displayederror, please refer to the Troubleshooting
section for assistance.
Once you have successfully logged in, you will see the Home page. On this page
you can view information about your LTE connection and system information. The
LTE Signal Strength indicator can be used to place your device. The IMEI and ICCID
are unique identiers for your device and may be required by your service provider.
At the bottom of the page, Device Reset allows you to reboot the device, while
Diagnostics brings up diagnostic and advanced configuration options. The
Diagnostics panel is intended for advanced users and debugging, and should not
be necessary in the course of normal usage.

This section is only available in Router Mode. To enable Router Mode, see “Router Mode” on page 23.
By default, Network Address Translation (NAT) blocks all remote requests. For cases where remote requests are needed, such as for remote access
or servers, port forwarding allows specic ports and protocols to travel from the Internet to specically designated hosts on the private network.
The device accepts remote requests for these services at your global IP address. It uses the specied TCP or UDP protocol and port number, and
redirects these requests to the server on your LAN with the LAN IP address you specify.
