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 specic 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 unit 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 unit in the presence of ammable
gases, fumes or potentially explosive atmospheres. Radio devices should not be used
anywhere that blasting operations are taking place.

Wireless routers receive and transmit radio frequency energy when power is on.
Interference can occur if used close to TV sets, radios, computers or inadequately
shielded equipment. Follow any special regulations and always power off your unit
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.

3 Installation

Mounting Tips

The Digi TransPort WR21 should be positioned on a at, level surface or via a wall-mount, rackmount, or DIN
rail mounting brackets (see the Accessories section on page 18 for all options). The unit is designed for indoor
use and should be mounted in a location with adequate ventilation. Also, do not expose the unit to extremes
of heat or cold, strong magnetic elds, or liquids.

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 rst.

The Digi TransPort WR21 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 network.

Page 9

Digi TransPort® WR21 Installation Guide

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
diversication. 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 www.digi.com. If

antennas other than the supplied antenna(s) are used, the separation between the two should be no less than

ve inches (5”).

Step 3) Connect the LAN Cable: Connect one end of the Ethernet cable to the “LAN 0” port on the unit and
the other end to a LAN port on a PC.

Step 4) 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).

Step 5) Connect the Power Supply:

Barrel Plug-Type Variants: Connect the barrel plug end of the power supply to the power connector on the

unit, and plug the other end into a wall outlet.

Notes:

◦ “International” units come with interchangeable Power Supply Adapters which can be used according

to regional needs.

◦ The barrel plug end of the power supply has a twist-lock connector which can be secured by rotating it

90 degrees once installed into the Digi TransPort unit.

Terminal Block Variants: Remove the pluggable connector from the unit and screw-down a proper power

source to its terminals. Once complete, reconnect the pluggable connector to the unit. A pin-out diagram is
located below.

Step 6) 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 ash to show that the unit is
busy. When the ashing stops, the unit has completed its self-test diagnostics and is ready to be congured.

Page 10

Digi TransPort® WR21 Installation Guide

4 Conguration

Once the unit has been installed and powered up, it needs to be congured to communicate with the LAN
and WAN. Conguration 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 conguration
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 192.168.1.1 with a subnet mask of 255.255.255.0. The unit has a
DHCP server enabled by default which can assign an appropriate IP address to your PC if the PC is congured
to get an IP address automatically. Alternatively you can manually congure your PC to be on the 192.168.1.x
network, for example, with an IP address of 192.168.1.2 and subnet mask of 255.255.255.0. Care should be
taken to ensure that the unit does not conict 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 http://192.168.1.1. 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.

If you are unable to connect to the Web Interface, please refer to the Troubleshooting section on page 16.

Step 2) ConguretheUnit: The easiest way to perform the initial conguration of the unit is by using the
Quick Start Wizard. This wizard allows you to congure the following items where applicable:

• Username and password

• LAN IP settings

• DHCP Server

• Mobile module and connection

Page 11

Digi TransPort® WR21 Installation Guide

The Quick Start Wizard is located in the Getting Started section on the Home menu.

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 WR21-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.

Page 12

Digi TransPort® WR21 Installation Guide

4.2.1.1 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 ash memory on the modem
module itself, not the Digi’s conguration le. 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 sufcient signal strength available to provision the modem.

• Always use MIP Prole 1 for manual provisioning unless specied otherwise by your carrier or Digi

Technical Support.

4.2.1.2 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 elds blank.

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 elds 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 elds in the Web Interface vary based on plan
and type of embedded modem. As noted above, always use MIP Prole 1 unless otherwise specied 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 conguring the unit, please refer to the Digi TransPort User Guide which is available
at www.digi.com.

4.2.2 Cellular: GSM

To congure the Wireless WAN/mobile interface on non-CDMA routers (GPRS/UMTS/HSPA), please refer to
the Application Guide “QN02 - Congure the wireless WAN (PPP) interface” which can be found on the Digi
Support site (http://www.digi.com/support/).

It is also essential to congure a dead link detection mechanism for routers using a Wireless WAN/mobile
interface (such as GPRS/HSDPA/CDMA). Please refer to the Application Guide “AN07 - Wireless - Wide
Area Network (W-WAN) Problem Detection and Recovery” which can also be found on the Digi Support site

(http://www.digi.com/support/).

Page 13

Digi TransPort® WR21 Installation Guide

4.3 Command Line Interface (CLI)

In order to congure the unit serially, ensure that the unit is connected to a PC (as outlined in Step 4 page 10 of
the Installation section). Also, terminal emulation software (such as HyperTerminal) will be required.

4.3.1 CLI Notes

• To view the current conguration settings, enter the command CONFIG C SHOW.

• To save changes made to the unit, enter the command CONFIG 0 SAVE.

• All entered commands will take effect immediately.

4.3.2 Communication Settings

Step 1) Congure the following settings for the unit:

COM Port: [select the appropriate port; typically COM1]

Baud Rate: 115200

Data Bits: 8

Stop Bits: 1

Parity: No Parity

Flow Control: None

Step 2) Ensure the connection is active by entering the command AT. If the device is functioning properly, it
will return the response OK.

Step 3) Ensure the COM port is setup correctly by entering the command ATI5.

4.3.3 Network Settings

To congure the unit with an IP address as part of an existing network, use the commands below.

Note: The DHCP server will still operate unless it is disabled.

Command Description
ETH 0 IPADDR XXX.XXX.XXX.XXX Sets the Eth 0 IP address
ETH 0 MASK XXX.XXX.XXX.XXX Sets the Eth 0 subnet mask

As an example, to assign the IP address 192.168.10.254/24, the following commands would be entered:

ETH 0 IPADDR 192.168.10.254

ETH 0 MASK 255.255.255.0

Note: When setting the mask to the above 255.255.255.0 value, it will not appear in the output of the
CONFIG C SHOW command as it is a default value.

Page 14

Digi TransPort® WR21 Installation Guide

To stop the DHCP server from serving addresses, use the following command:

Command Description
DHCP 0 IPMIN X Removes the minimum IP address that will be server via

DHCP, disabling the DHCP server

As an example, to stop the DHCP sever from DHCP requests, enter the command DHCP 0 IPMIN !. The !
variable is used to remove a value or set it back to its default.

To retain the DHCP server, but on a different subnet, the following parameters will need to be congured:

Command Description
DHCP 0 IPMIN x.x.x.x Minimum IP address to assign, the start of the DHCP pool
DHCP 0 IPRANGE The number of IP addresses in the DHCP pool
DHCP 0 GATEWAY x.x.x.x The IP gateway address the DHCP clients should use

(normally this router’s LAN IP address)

DHCP 0 MASK x.x.x.x The subnet mask DHCP clients should use
DHCP 0 DNS The DNS server DHCP clients should use

5 Troubleshooting

5.1 Troubleshooting Resources

There are several resources available to you for support of your Digi product or resolving conguration
difculties at Digi’s Support site, http://www.digi.com/support/. Try these troubleshooting steps to eliminate
your problem. After working through these steps and your problem is not solved, try the resources listed below.

1. Digi’s Support knowledge base: http://www.digi.com/support/kbase.

2. Digi TransPort support documents: http://ftp1.digi.com/support/documentation/transport/technicalnotes.htm.

3. If the knowledge base or support forums do not have the information you need, ll out an Online Support
Request via: http://www.digi.com/support/eservice/login.jsp?p=true. You will need to create a user account if
one is not already set up.

When submitting a support request, please include a copy of the debug.txt le from the unit’s ash. This will
greatly improve the quality of the initial response you receive. Without this le, it is often very difcult for the
support team to provide accurate answers to your queries.

For instructions on how to download the debug.txt le from the unit, view the online document “QN24 ­Extracting the debug.txt le from a Digi TransPort or Sarian router”.

5.2 UnabletoopentheWebInterface

Ensure that the LAN cable is properly connected to the LAN port and that the “LAN” status indicator on the
front of the unit is illuminated. If it is not, then there is a problem with either the LAN cable or the device it is
connecting to. If the status indicator is illuminated, check that the PC can communicate with the unit. To do
this, open the Command Prompt window on your PC and enter the command “ping 192.168.1.1”. If you do not

get a response, then the problem could be one of the following:

• The IP address of the unit has been changed from its default of 192.168.1.1. Use the Digi TransPort

Connection Wizard (which can be downloaded from the Support area at Digi.com or the Digi Device
Discovery Tool). It can usually discover the unit on a network as long as the unit’s rewall has not been
enabled.

• PC IP conguration. The PC’s LAN interface that is connected to the unit should be congured to “Obtain

an IP address automatically”. If required, the Digi TransPort Connection Wizard can be used to congure
the PC.

• Check the PC’s LAN connection and any LAN device (e.g. Ethernet switch) that is used to interconnect

to the unit.

• Refresh the PC’s IP settings by opening a command window and enter “ipcong /release” then “ipcong

/renew”.

• ARP resolution. Clear the PC’s ARP cache with the command “arp –d *”, then retry the ping command. If

you do get a response but are unable to view the Web Interface, then there is most likely a problem with

your web browser conguration.

5.3 UnabletologintotheWebInterface

Access to the unit can be achieved via any of the asynchronous serial ports. Connect your PC to the unit using
a “straight through” RS232 serial cable. This will allow you to change the conguration via the Command Line
Interface (CLI). Please refer to the Digi TransPort User Guide for information on how to use the CLI. The User
Guide can be downloaded from the Digi Support site. If you have further questions about your product please
contact Digi Technical Support (see page 2 for contact information).
