Special notes on safety for wireless routers
Digi International products are designed to the highest standards of safety and international
standards compliance for the markets in which they are sold. However, cellular-based products
contain radio devices which require specific consideration. Please take the time to read and
understand the following guidance. Digi International assumes no liability for an end user’s failure
to comply with these precautions.
Wireless routers incorporate a wireless radio module. Users should ensure that the antenna(s) is
(are) positioned at least 1 meter away from themselves and other persons in normal operation.
When in a hospital or other health care facility, observe the restrictions on the use of mobile phones.
Do not use the router in areas where guidelines posted in sensitive areas instruct users to switch off
mobile phones. Medical equipment may be sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be
affected by interference from cellular terminals such as the wireless routers when places close to
the device. If in doubt about potential danger, contact the physician or the manufacturer of the
device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep
the wireless router away from the pacemaker while it is on.
Wireless routers must NOT be operated on aircraft. The operation of wireless appliances in an
aircraft is forbidden to prevent interference with communications systems. Failure to observe these
instructions may lead to the suspension or denial of cellular services to the offender, legal action, or
both.
As with any electrical equipment, do not operate the router in the presence of flammable gases,
fumes or potentially explosive atmospheres. Do not use radio devices anywhere that blasting
operations occur.
Wireless routers receive and transmit radio frequency energy when power is on. Interference can
occur when using the router close to TV sets, radios, computers or inadequately shielded
equipment. Follow any special regulations and always power off your router wherever forbidden or
when it may cause interference or danger.
SOS IMPORTANT! Wireless routers operate using radio signals and cellular networks cannot be
guaranteed to connect in all possible conditions. Therefore, never rely solely upon any wireless
device for life critical communications.
Warning: For environments where the temperature is 55° C or above, this device must be installed
in a restricted access area.
Product Disposal Instructions
The WEEE (Waste Electrical and Electronic Equipment: 2002/96/EC) directive has been introduced to
ensure that electrical/ electronic products are recycled using the best available recovery techniques
to minimize the impact on the environment.
This product contains high quality materials and components which can be recycled. At the end of
its life this product MUST NOT be mixed with other commercial waste for disposal. Check with the
terms and conditions of your supplier for disposal information.

Special notes on safety for wireless routers
Digi International products are designed to the highest standards of safety and international
standards compliance for the markets in which they are sold. However, cellular-based products
contain radio devices which require specific consideration. Please take the time to read and
understand the following guidance. Digi International assumes no liability for an end user’s failure
to comply with these precautions.
Wireless routers incorporate a wireless radio module. Users should ensure that the antenna(s) is
(are) positioned at least 1 meter away from themselves and other persons in normal operation.
When in a hospital or other health care facility, observe the restrictions on the use of mobile phones.
Do not use the router in areas where guidelines posted in sensitive areas instruct users to switch off
mobile phones. Medical equipment may be sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be
affected by interference from cellular terminals such as the wireless routers when places close to
the device. If in doubt about potential danger, contact the physician or the manufacturer of the
device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep
the wireless router away from the pacemaker while it is on.
Wireless routers must NOT be operated on aircraft. The operation of wireless appliances in an
aircraft is forbidden to prevent interference with communications systems. Failure to observe these
instructions may lead to the suspension or denial of cellular services to the offender, legal action, or
both.
As with any electrical equipment, do not operate the router in the presence of flammable gases,
fumes or potentially explosive atmospheres. Do not use radio devices anywhere that blasting
operations occur.
Wireless routers receive and transmit radio frequency energy when power is on. Interference can
occur when using the router close to TV sets, radios, computers or inadequately shielded
equipment. Follow any special regulations and always power off your router wherever forbidden or
when it may cause interference or danger.
SOS IMPORTANT! Wireless routers operate using radio signals and cellular networks cannot be
guaranteed to connect in all possible conditions. Therefore, never rely solely upon any wireless
device for life critical communications.
Warning: For environments where the temperature is 55° C or above, this device must be installed

Special notes on safety for wireless routers
Digi International products are designed to the highest standards of safety and international
standards compliance for the markets in which they are sold. However, cellular-based products
contain radio devices which require specific consideration. Please take the time to read and
understand the following guidance. Digi International assumes no liability for an end user’s failure
to comply with these precautions.
Wireless routers incorporate a wireless radio module. Users should ensure that the antenna(s) is
(are) positioned at least 1 meter away from themselves and other persons in normal operation.
When in a hospital or other health care facility, observe the restrictions on the use of mobile phones.
Do not use the router in areas where guidelines posted in sensitive areas instruct users to switch off
mobile phones. Medical equipment may be sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be
affected by interference from cellular terminals such as the wireless routers when places close to
the device. If in doubt about potential danger, contact the physician or the manufacturer of the
device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep
the wireless router away from the pacemaker while it is on.
Wireless routers must NOT be operated on aircraft. The operation of wireless appliances in an
aircraft is forbidden to prevent interference with communications systems. Failure to observe these
instructions may lead to the suspension or denial of cellular services to the offender, legal action, or
both.
As with any electrical equipment, do not operate the router in the presence of flammable gases,
fumes or potentially explosive atmospheres. Do not use radio devices anywhere that blasting
operations occur.
Wireless routers receive and transmit radio frequency energy when power is on. Interference can
occur when using the router close to TV sets, radios, computers or inadequately shielded
equipment. Follow any special regulations and always power off your router wherever forbidden or
when it may cause interference or danger.
SOS IMPORTANT! Wireless routers operate using radio signals and cellular networks cannot be
guaranteed to connect in all possible conditions. Therefore, never rely solely upon any wireless
device for life critical communications.
Warning: For environments where the temperature is 55° C or above, this device must be installed
in a restricted access area.

Special notes on safety for wireless routers
Digi International products are designed to the highest standards of safety and international
standards compliance for the markets in which they are sold. However, cellular-based products
contain radio devices which require specific consideration. Please take the time to read and
understand the following guidance. Digi International assumes no liability for an end user’s failure
to comply with these precautions.
Wireless routers incorporate a wireless radio module. Users should ensure that the antenna(s) is
(are) positioned at least 1 meter away from themselves and other persons in normal operation.
When in a hospital or other health care facility, observe the restrictions on the use of mobile phones.
Do not use the router in areas where guidelines posted in sensitive areas instruct users to switch off
mobile phones. Medical equipment may be sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical equipment and hearing aids can be
affected by interference from cellular terminals such as the wireless routers when places close to
the device. If in doubt about potential danger, contact the physician or the manufacturer of the
device to verify that the equipment is properly shielded. Pacemaker patients are advised to keep
the wireless router away from the pacemaker while it is on.
Wireless routers must NOT be operated on aircraft. The operation of wireless appliances in an
aircraft is forbidden to prevent interference with communications systems. Failure to observe these
instructions may lead to the suspension or denial of cellular services to the offender, legal action, or
both.
As with any electrical equipment, do not operate the router in the presence of flammable gases,
fumes or potentially explosive atmospheres. Do not use radio devices anywhere that blasting
operations occur.
Wireless routers receive and transmit radio frequency energy when power is on. Interference can
occur when using the router close to TV sets, radios, computers or inadequately shielded
equipment. Follow any special regulations and always power off your router wherever forbidden or
when it may cause interference or danger.
SOS IMPORTANT! Wireless routers operate using radio signals and cellular networks cannot be
guaranteed to connect in all possible conditions. Therefore, never rely solely upon any wireless
device for life critical communications.
Warning: For environments where the temperature is 55° C or above, this device must be installed
in a restricted access area.

Use the web interface
Digi TransPort routers have a built-in web interface for configuring the device, managing the
network and connections, and managing applications. This section describes the web interface.
By default, Digi Transport routers have a static IP address of 192.168.1.1 with DHCP server enabled.
To access the router using a web browser:
1 If the Digi TransPort router is not already connected to a LAN, connect an Ethernet cable
between the LAN port on the Digi Transport and your PC.
NoteAll TransPort WR models are auto-sensing for 10/100 operation. Most models are also auto
MDI/MDX, such as will automatically work with either a straight-through or cross-over
cable.
2 Make sure your PC is configured to automatically receive an IP address by selecting Start >
Control Panel > Network > Configuration and verifying the configuration.
3 Open a web browser. Enter the router’s Ethernet IP address (192.168.1.1) into your web browser
after configuring your PC to have an address on the same subnet. A login page appears.
4 Enter the default username, username, and the default password, password and click Log In
button. The password appears as a series of dots for security purposes.
NoteDigi recommends changing the username and password for all users away from their
defaults. See Change the default username and password for a user.

Signal strength indicators on the Mobile status page
On routers equipped with W-WAN modules, there are three LEDs on the front panel that indicate the
strength of the signal, as shown in the following table. The web interface also displays signal
strength in the Signal Strength field on the Management > Network Status > Mobile page:
The signal strength is shown in negative dB, which means that the stronger the signal, the lower the
number. As a guide, -51 dBm is a very strong signal, normally only obtained very close to a cell site. 115 dBm represents no signal. If your router reports -115dBm, try reorienting the antenna or
consider adding an external antenna.
The following values are fairly specific to LTE. At 2G/3G technology, any strength lower than -100
dBm becomes unusable.
LEDs lit Signal Strength
None No Signal: under -113 dBm
1 Weak signal: -112 dBm to -87 dBm
2 Good signal: -86 dBm to -71 dBm
3 Excellent signal: -70 dBm to -51 dBm

Web interface wizards
The wizards page contains wizards that simplify common configuration tasks. These wizards set the
minimum number of parameters from the router’s factory defaults to complete the required
configuration task. Because these wizards configure a generic group of settings, using them to
configure features may not be suitable for specific configuration scenarios.
Quick Start wizard
The Quick Start wizard displays the options required for basic configuration of the Eth 0, WLAN,
and WWAN interfaces. From this wizard page, you can configure Ethernet LAN interface.
You can get IP settings assigned automatically if your network supports this capability. Otherwise,
you can assign the IP settings appropriate for your network.
