[Rear of Unit]
Step 1)(SIM card models only) - Install the SIM card(s): SIM card(s) should be inserted into SIM Sockets
as illustrated in the above Front View image. For SIM 1, the contacts should be face down. For SIM 2, the
contacts should be face up. In both cases, the end of the SIM card with the chamfered corner should be
inserted first.
Note: For WR44-C models, not all networks require/support the use of Removable User Identity Modules
(R-UIM’s). If your service provider does not support R-UIMS, the unit may have been “provisioned” for use on
your chosen network before you receive it and this step of the installation procedure will not be required. If the
unit has not been provisioned, you will need to contact your service provider to obtain an “IMSI” and “NAI” in
order to provision the unit manually.

TransPort® WR44 Installation Guide
The TransPort WR44 also allows for dual network installations where one wireless service can be used as a
back-up in the event that the primary service fails. These installations cannot be used to access two networks
simultaneously. By default, SIM 1 is used for access to the primary network and SIM 2 is used for the back-up
For added security, Digi offers a “SIM Slot Cover Plate” that can be installed on the unit to deter theft or
tampering of the SIM cards, (see the Accessories section on page 22 for more information).
Step 2)Connect the Cellular (WWAN) Antenna(s): Connect the cellular antenna to the “WWAN PRIMARY”
connector (SMA Female) on the unit. If the unit is equipped with a secondary cellular antenna connector
(WWAN SECONDARY), it is highly recommended to connect an additional antenna to this connector for
diversification. Dual antennas will provide improved signal strength thus better performance.
Note: For most applications, the antenna(s) included with the unit will provide suitable reception, but some
circumstances/environments may require a higher quality antenna or one mounted in a different location. If
this is the case, Digi has many antenna options to chose from -- please contact us or visit If
antennas other than the supplied antenna(s) are used, the separation between the two should be no less than
five inches (5”).
Step 3)(Wi-Fi models only) – Connect the Wi-Fi Antennas: Connect the Wi-Fi antennas to the ‘WIFI
PRIMARY and WIFI SECONDARY’ antenna connectors (SMA Male).
Step 4)Connect the LAN Cable: Connect one end of the Ethernet cable to the “LAN” port on the unit and the
other end to a LAN port on a PC.
Step 5)Connect the Serial Cable (optional): Connect one end of the serial cable (not included) to the
“SERIAL 0” port on the unit and other end to the serial port on a third-party serial terminal device. If you wish
to connect the unit to a PC, it is recommended that you purchase Digi’s serial cable (P/N: 76000858).
Some TransPort models also include additional serial ports which have RJ45 connectors. For those models,
Digi offers the following serial cables for connectivity:
P/N: 76000855 -- RJ45 to DB9 Female - 6’
P/N: 76000856 -- RJ45 to DB25 Male - 6’
P/N: 76000857 -- RJ45 to DB25 Female - 6’
TransPort® WR44 Installation Guide
4 Configuration
Once the unit has been installed and powered up, it needs to be configured to communicate with the LAN
and WAN. Configuration is performed either using the Command Line Interface (CLI) or the Web Interface.
The Web Interface (accessed via a web browser e.g. Firefox, IE, Chrome) is the recommended configuration
option for most users.
Note: You will not be able to use the unit for remote communication until you have subscribed to a suitable
mobile/cellular wireless network service.
4.1 Network Settings
The default IP address for the LAN port is with a subnet mask of The unit has a
DHCP server enabled by default which can assign an appropriate IP address to your PC if the PC is configured
to get an IP address automatically. Alternatively you can manually configure your PC to be on the 192.168.1.x
network, for example, with an IP address of and subnet mask of Care should be
taken to ensure that the unit does not conflict with other devices that may already be on the network.
4.2 Web Interface
Step 1)Connect to the Web Interface: Open a Web browser (e.g. Firefox, IE, Chrome) on your PC and
navigate to If successful, you will be prompted to enter a username and password. The
default username is “username”, and the default password is “password”. After you have logged in, it is
strongly recommended that you immediately change the default username and password.
Step 6)Connect the Power Supply: Depending on model, the unit will either come with an AC power sup­ply,
4-pin DC power cord, or a Fleet power cord. Instructions for all options are described below.
AC Power Supply - Connect the locking barrel end of the power supply to the “MAIN” connector on the
unit, and plug the other end into a wall outlet. “International” units come with interchangeable Power Supply
Adapters which can be used according to regional needs.
4-Pin DC Power Cord - Connect the 4-pin molded end of the cord to the “AUX” connector on the unit, and wire
the four bare wires accordingly to your needs. The red and black wires provide basic DC power input, and the
blue and green wires are programmable signal lines.
WARNING: Only one of the power connectors should be used. Never apply power to both the MAIN and AUX
ports at the same time.
Fleet Power Cord - Connect the 4-pin molded connector to the “Pwr” port on the unit. Connect the locking
barrel jack to the “MAIN” connector on the unit. Finally, wire the two bare wires accordingly to your needs.
For sample wiring diagrams and pinout information, see the 4-Pin DC Power Cord and Fleet I/O Interface User‘s
Guides, which can be found online at
Step 7)When the unit is powered-up, the POWER indicator will illuminate and the unit will initiate a series of
diagnostic self-tests. During this process one or more of the other indicators will flash to show that the unit is
busy. When the flashing stops, the unit has completed its self-test diagnostics and is ready to be configured.

The Quick Start Wizard is located in the Getting Started section on the Home menu.
TransPort® WR44 Installation Guide CDMA Provisioning
CDMA provisioning is different from GSM since CDMA (in most cases) does not use a SIM card.
The CDMA modem provisioning process creates a CDMA data connection to the mobile carrier network. This
authenticates the modem and retrieves account information which is written to flash memory on the modem
module itself, not the Digi’s configuration file. As the mobile account information is stored on the CDMA module,
performing a factory reset on the unit will not remove provisioning information from the CDMA module.
Important points:
The modem must be provisioned on the network before it will communicate.
The modem must be in coverage area of the native carrier. It cannot be roaming.
There must be sufficient signal strength available to provision the modem.
Always use MIP Profile 1 for manual provisioning unless specified otherwise by your carrier or Digi
Technical Support. Automatic vs. Manual Provisioning
There are two types of CDMA provisioning: Automatic and Manual. This varies between carriers and even
within carriers. Settings in the Web Interface vary based on carrier plan. Below are examples for Verizon
Wireless and Sprint:
Verizon Wireless always uses Automatic. This means that no further settings are required in the Web Interface
- simply press Start in the Automatic section and leave the fields blank.
4.2.1 Cellular: CDMA
If your unit is to be used on a CDMA network, the embedded module must be provisioned on the network
before it can make a connection.
Note: If your unit uses a Gobi module (indicated by a model number of WR44-U5xx-xxx-xx), and you did not
select the appropriate CDMA carrier via the Quick Start Wizard, you must run the GOBI Module Carrier Wizard
before provisioning can be successfully completed.
To provision the CDMA mobile device, navigate to the CDMA Provisioning section by clicking on Network >
Mobile > CDMA Provisioning.
Sprint has two types of plans, Vision for standard Internet connections and DataLink for private IP plans:
1. Sprint Vision uses Automatic provisioning. There are three fields of information that may need to be
populated in the Automatic screen. Check with Sprint for correct values (if required).
2. Sprint DataLink requires Manual provisioning. The required fields in the Web Interface vary based on plan
and type of embedded modem. As noted above, always use MIP Profile 1 unless otherwise specified by
your carrier or Digi Technical Support.
Check with your carrier for information about the type of provisioning required and what, if any, data is required
to be entered.
For more information on configuring the unit, please refer to the Digi TransPort User Guide which is available
4.2.2 Cellular: GSM
To configure the Wireless WAN/mobile interface on non-CDMA routers (GPRS/UMTS/HSPA), please refer to
the Application Guide “QN02 - Configure the wireless WAN (PPP) interface” which can be found on the Digi
Support site (
