Introduction to Digi TransPort routers
The Digi TransPort WR family of 3G/4G cellular routers offers an all-in-one mobile
communications solution with true enterprise class routing, security and firewall. These
multifunction cellular routers feature a flexible design with optional integrated Wi-Fi access point
(with multi SSID) / client, USB, serial, VDSL, 1-, 2- or 4-port Ethernet switch with VLAN. Additional
configuration options include multiple serial ports (async or sync), GPS or telemetry I/O.
The Digi TransPort family offers an advanced routing, security and firewall feature set including
stateful inspection firewall and integrated VPN. Enterprise class protocols incorporate BGP, OSPF
and VRRP+, a patented technology built upon the popular VRRP failover standard providing true
auto-sensing, auto-failure and auto-recovery of any line drop.
Digi TransPort WR routers are ideal for transportation, POS, energy, medical, financial and digital
signage as well as cellular backup and remote device connectivity applications.
Digi management solutions provide easy setup, configuration and maintenance of large
installations of remote Digi TransPort devices. Device Cloud by Etherios offers web-based device
management for remote Digi cellular routers and gateways. Also available is the Windows based
Digi Remote Manager for customer installed device management and reporting. Digi TransPort
routers have the following features:
• Enterprise class cellular routers with advanced dynamic routing, security and firewall
features.
• High speed LTE/4G router with fall back to both GSM and CDMA 3G/2G technologies.
• Optional integrated Wi-Fi access point and multiport Ethernet switch.
• Flexible interfaces including serial (async/sync), GPS, VDSL, USB, CAN Bus and telemetry I/O,
with flexible DC power options.
• Powerful integrated end user programming.
• Remote Management via windows remote management software or cloud hosted Device
Cloud.

Signal strength indicators
Digi TransPort User Guide 16
Signal strength indicators
On units equipped with W-WAN modules, there are three LEDs on the front panel that will
indicate the strength of the signal, as shown in the table below.
LEDs lit Signal Strength
None Under -113 dBm (effectively no
signal)
1 -112 dBm to -87 dBm (weak
signal)
2 -86 dBm to -71 dBm (medium
strength signal)
3 -70 dBm to -51 dBm (strong
signal)

Warnings
Radio equipment - Canadian warning statements
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject
to the following two conditions: (1) this device may not cause interference, and (2) this device
must accept any interference, including interference that may cause undesired operation of the
device.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of
a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce
potential radio interference to other users, the antenna type and its gain should be so chosen
that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for
successful communication.
This radio transmitter (identify the device by certification number, or model number if Category
II) has been approved by Industry Canada to operate with the antenna types listed below with the
maximum permissible gain and required antenna impedance for each antenna type indicated.
Antenna types not included in this list, having a gain greater than the maximum gain indicated for
that type, are strictly prohibited for use with this device.
OEM responsibilities
The WR44v2 Module has been certified for integration into products only by OEM integrators
under the following conditions:
1. The antenna(s) must be installed such that a minimum separation distance of 20cm is
maintained between the radiator (antenna) and all persons at all times.
2. The transmitter module must not be co-located or operating in conjunction with any other
antenna or transmitter.
As long as the two conditions above are met, further transmitter testing will not be required.
However, the OEM integrator is still responsible for testing their end-product for any additional
Name / Model Gain Impedance
BEC C424-510065-A 1.8dBi 50? Nominal

Radio equipment - FCC warning statement
Digi TransPort User Guide 18
compliance requirements required with this module installed (for example, digital device
emissions, PC peripheral requirements, etc.).
Note In the event that these conditions can not be met (for certain configurations or co-location
with another transmitter), then Industry Canada certification is no longer considered valid
and the IC Certification Number can not be used on the final product. In these
circumstances, the OEM integrator will be responsible for re-evaluating the end product
(including the transmitter) and obtaining a separate Industry Canada authorization.
End product labeling
The WR44v2 Module is labeled with its own IC Certification Number. If the IC Certification
Number is not visible when the module is installed inside another device, then the outside of the
device into which the module is installed must also display a label referring to the enclosed
module. In that case, the final end product must be labeled in a visible area with either of the
following:
• Contains Transmitter Module IC: 1846A-55M1644
• Contains IC: 1846A-55M1644
The OEM of the WR44v2 Module must only use the approved antenna(s) listed above, which have
been certified with this module.
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module or change RF related parameters in the user’s manual of the end
product.
Note To comply with Industry Canada RF radiation exposure limits for general population, the
antenna(s) used for this transmitter must be installed such that a minimum separation
distance of 20cm is maintained between the radiator (antenna) and all persons at all times
and must not be co-located or operating in conjunction with any other antenna or
transmitter.
Radio equipment - FCC warning statement
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions:
• This device may not cause harmful interference.
• This device must accept any interference received, including interference that may cause
undesired operation.
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. End users must follow the specific operating instructions for satisfying RF exposure
compliance. This transmitter must not be co-located or operating in conjunction with any other
antenna or transmitter.
Changes or modifications not expressly approved by the party responsible for compliance could
void the user's authority to operate the equipment.
The antenna(s) used for this transmitter must be installed to provide a separation distance of at
least 20 cm from all persons.

Radio equipment - FCC warning statement
Digi TransPort User Guide 19
Any product using the WR44v2 Wi-Fi module must have a label stating ‘Contains FCC ID: MCQ-
55M1644B’ placed on it in line with FCC labelling regulations.
Antenna specification: RP-SMA
This module obtained its complete certification by using the antenna described here. End users
in North America should use an antenna that matches these specifications to maintain the
module’s certification. Antennas of the same type but operating with a lower gain may be used.

Digi TransPort command line interface
Using a Web browser to modify text box or table values in the configuration pages is the simplest
way to configure the unit and this process is described in the next chapter. However, if you do not
have access to a Web browser, the unit can be configured using text commands. These
commands may be entered directly at one of the serial ports or via a Telnet session. Remote
configuration is also possible using Telnet or X.25.
Note Low level permission users were designed to work in Web UI only. Command line use is
not supported.
To use the serial ports you will need a PC and some communications software such as
HyperTerminal ™ (supplied with Windows) or TeraTerm™. The same commands may also be used
to configure the unit remotely via Telnet, X.25 or V.120.
There are several types of text command:
AT commands and S registers
Digi TransPort supports AT commands and Special registers (S registers) to maintain
compatibility with modems when the unit is used as a modem replacement.
Application commands
Application commands are specific to Digi International products and control most features of
the unit when not using the Web interface.
X.3 commands
These are standard X.3 commands which are used only in X.25 PAD mode
