Special Notes on GSM/3G Wireless Safety
Digi International products are designed to the highest standards of safety and
international standards compliance for the markets in which they are sold. However, GSM
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 aerial is positioned at least 1 metre 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 placed 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, you should not operate your wireless
router in the presence of flammable 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 while
switched on. Remember that interference can occur if it is used close to
TV sets, radios, computers or inadequately shielded equipment. Follow
any special regulations and always switch off your wireless router
wherever forbidden or when you suspect that 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, you should never rely solely upon any wireless
device for life critical communications.

1 Introduction
The MR4110, ER4110 and HR4110 are compact IP routers that facilitate the transmission
of data over wireless GSM or 3G networks. The data rates and network types supported
depend on the model type.
GPRS (General Packet Radio System) is an IP-based data transmission service that runs
over GSM wireless networks. It is an “always-on” protocol which means that once the
router has “attached” to the network, data can be transmitted and received on demand,
i.e. it is not necessary to make a call first.
EDGE is an enhanced version of GPRS which offers increased data transfer rates.
UMTS and HSDPA are the 3rd generation (3G) of GSM wireless networks, and as such
have much higher data transmission rates.
GPRS/EDGE routing is ideal for applications that are characterised by frequent
transmission of relatively small amounts of data, e.g. ATMs (cash-dispenser), remote
monitoring and data collection (telemetry) and credit/debt card authorisation.
UMTS/HSDPA routing is ideal for larger amounts of data or for situations where the speed
of data transfer is critical. Typical applications include backup for broadband wireline
services, video transmission, etc.
HSUPA routing is available as an optional upgrade on the HR4110. HSUPA is able to
provide a much greater amount of upstream bandwidth than HSDPA. In addition, the
downstream bandwidth is increased too. This makes HSUPA ideal for live broadcast
quality video transmissions.
The routers can be configured either by using commands entered at the serial port (much
like a modem), or via the built-in Web interface. We recommend that you use the Web
interface whenever possible.
In addition to many standard LAN and Internet protocols such as PPP, the xR4110 series
products provide a combination of powerful but easy to use configuration, management
and diagnostic tools. This makes them simple and cost-effective solutions for migrating
existing terminal or telemetry equipment, which use wired networks (PSTN, ISDN, etc.), to
wireless operation.
1.1 Front Panel Features
The front panel of the unit incorporates the USB host connectors, eleven LED indicators
and the two SIM card-holders as shown in the following illustration (ER4110):

Rear Panel Features
The functions of these connectors are described in the following table:
12V DC
This jack socket is used to connect the unit to the power supply
using 12V DC mains adapter.
GPS
If the GPS option is not fitted, this connector will be replaced with
a “GPS OPTION NOT FITTED” label.
If you have purchased the GPS option the unit will be fitted with
an SMA antenna connector.
SERIAL 0
This 25-way D socket provides an asynchronous RS2322 serial
port which may be used to connect the router to a compatible
serial device. The unit is supplied with a suitable 2 metre serial
cable. To comply with EMC requirements it should not be used
with a longer cable.
GPRS/EDGE
This SMA connector is used to fit the wireless antenna supplied
with the unit. A range of alternative antennas are available for
purchase separately.
LAN
The socket labelled LAN is used to connect the unit to a
10/100Base-T LAN using the 2-metre STP (Shielded Twisted
Pair) cable supplied or a suitable alternative. This port is autosensing for speed and wiring (straight-through or cross-over). To
comply with EMC requirements it should not be used with nonSTP cable.
EXP.
The socket labelled EXP. may be used to connect various
accessories supplied by Digi International. For further information
please contact your supplier.
Reset switch
This is located on the underside of the unit near the front. Pressing the switch gently with
the tip of a pen or other suitable implement will generate a hardware reset.

2 Installation
The xR4110 series products are designed for indoor use (office or home). The router
should be positioned on a smooth, level surface making sure that there is adequate
ventilation. Do not expose the router to extremes of heat or cold, strong magnetic fields or
liquids.
It is important to remember that these products are wireless devices just like a mobile
phone, so they will only operate reliably over the GSM network if there is a good signal.
For many applications the stub aerial provided will be suitable but in some circumstances
it may be necessary to use a window-mounted or magnetically mounted aerial with an
extended cable to allow the aerial itself to be positioned to provide the best possible signal
reception. Digi International can supply a range of suitable aerials.
Important Note
If you are going to be using the Sar/OS Connection Wizard to configure the unit‟s Ethernet
port and also connect it to your GSM/3G network, skip this section and proceed to
Configuration.
Step 1 - Installing the SIM card(s)
The router incorporates two separate SIM card holders so that if your application
demands it, you may install SIM cards for two different networks. This means that one
wireless service may be used as a back-up service in the event that the primary service
fails in some way. By default, SIM 1 is the default SIM used for access to the primary
network and SIM 2 is used for the back-up network.
Note:
SIM 1 and SIM 2 cannot be used to access two networks simultaneously.
The SIM card(s) should be inserted into SIM cardholders on the right of the front panel as
illustrated below.
In both cases, the end of the SIM card with the chamfered corner should be inserted first.
For SIM 1 the contacts should be face down. For SIM 2 the contacts should be face up.

Step 2 – Fitting the wireless antenna
The router is supplied with a “stub” antenna suitable for with the model you have ordered.
Alternatively you may have ordered a different type of antenna separately. In either case
this should be screwed onto the SMA aerial connector on the rear of the unit.
If the HSUPA option is purchased, 2 antennas will be supplied, both must be attached to
the router. These antennas must not be replaced with external antennas as the spacing
between the two antennas is critical.
Step 3 – Connecting the LAN cable
Plug one end of one of the supplied 2 metre CAT5 STP cable into the RJ45 socket
labelled LAN 0. Plug the other end into the LAN socket on your PC or notebook.
Step 4 – Connecting the serial cable
For connection to a serial terminal device, connect the 25-way D plug on the serial cable
provided to the SERIAL connector on the rear of the unit. Connect the other end of the
cable (9-way D socket) to the terminal. If the serial connector on the terminal is not a 9way D plug, you will need a suitable adapter.
Step 5 – Connecting the GPS antenna (if applicable)
If you have purchased the router with the GPS option fitted, this connector is used to
connect the GPS antenna. A range of suitable antennas are available for purchase
separately. To connect the antenna, screw the SMA termination firmly onto the rear panel
connector.
Step 6 – Connecting the power supply
Plug the jack plug on the mains adapter into the socket labelled 12V DC. When power is
first applied, the ON 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 is ready to use.
The unit is now ready to be configured.

3 Configuration
Once the router has been installed and powered up, you must now configure it to
communicate with your network and the Internet. The easiest way to do this is to use the
Sar/OS Connection Wizard, available from the Digi website. The Sar/OS Connection
Wizard will take you step-by-step through the process of configuring the router.
You can choose to just configure the unit‟s Ethernet port (so that you can connect to it
over your LAN in order to configure it fully), or you can use the wizard to configure the
unit‟s Ethernet port, and at the same time connect it to your wireless network.
Using the wizard means that you will not have to change the IP address of your PC.
Rather, you will be able to change the IP address of the router to match the subnet your
PC is already on.
Note: The default IP address for the LAN 0 port is 192.168.0.99, with a Class C subnet
(255.255.255.0). Setting your PC’s IP address to one on the same subnet (192.168.0.*)
will enable you to connect to the unit’s Web interface. You will then be able to configure
the unit manually.
Step 1 – Install the Connection Wizard
Download the connection wizard from the Digi website and install the software on your
PC.
Step 2 – Run the Wizard
Once the wizard has been installed on your PC, run it from the Windows Start menu.
Step 3 – Decide which configuration method to use
Choose to either configure the unit‟s Ethernet port only, or configure the unit‟s Ethernet
port and at the same time connect it to your wireless network.
If you choose to configure the unit‟s Ethernet port only, you must have completed all the
installation steps listed in the previous section.
Step 4 – Configure the unit
Follow the on-screen instructions to configure the unit according to the method you have
chosen. Once complete you will be able to browse to the unit and configure it using your
web browser.
