Special Notes on 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,

wireless 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 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.

Transport SR Series Installation Guide

1 Introduction

The Transport SR and other models described in this guide are compact IP routers that

facilitate the transmission of data over UMTS, HSDPA, EVDO, GPRS, EDGE and/or

PSTN networks. All models incorporate a 4-port 10/100 Ethernet switch. Depending on

the model, each unit also incorporates one or more WAN interfaces as follows:

SR44-E, H, U –wireless GPRS/EDGE/UMTS/HSDPA/HSUPA only

SR44-C –wireless CDMA/IXRTT/EVDO only

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, Transport SR

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, a number of LED

indicators depending on the model and the two SIM card-holders as shown in the

following illustration (GSM models):

USB Host Connectors

The USB host connectors may be used to connect compatible USB client devices such as

memory sticks, serial adapters, etc.

Transport SR Series Installation Guide

Status Indicators

The status indicators operate as follows:

Illuminates steady red when power is applied.

LAN 0, 1, 2, 3

Illuminate steady when there is a network connection to the

associated LAN port and flash when data is transmitted or

received.

W-WAN:

NET, SIM,

DAT

These indicators display the wireless WAN status as follows:

NET –Illuminates green when a wireless network has been

detected.

SIM –Illuminates green when a valid SIM card is installed in the

unit.

DAT –Flashes green when data is being transmitted or received.

SIGNAL

The three indicators labelled SIGNAL illuminate to indicate the

wireless signal strength as follows:

None illuminated < -113 dBm (effectively no signal)

1 LED illuminated >= -112 dBm and <= -87dBm (weak)

2 LED‟s illuminated >= -86dBm and <= -71dBm (medium)

3 LED‟s illuminated >= -70dBm and <= -51dBm (strong)

PSTN:

OH, CD, DAT

On the Transport SR models with a PSTN interface, these

indicators operate as follows:

OH –Illuminates green when the modem has gone off-hook.

CD –Illuminates green when the unit has connected to a remote

modem and asserted the Carrier Detect signal at the serial port.

DAT –flashes green when the unit has connected to a remote

modem and data is being transferred.

SERIAL:

0, 1

These indicators operate in one of two software configurable

modes:

Connection Mode: Illuminate steady if a terminal is connected to

the serial port and the DTR signal is on. Flash when data is

transmitted or received.

DTR Mode: Flash when data is transmitted or received only.

Transport SR Series Installation Guide

SIM Card Sockets

The two sockets at the right side of the front panel are for the GSM SIM card(s) that you

will receive from your service providers. Details of how to insert these correctly are given

in section 2 below.

CDMA models do not require SIM cards and therefore do not have SIM card sockets.

Rear Panel Features

(SR44 shown with PSTN option)

The functions of these connectors are described in the following table:

12V DC

This socket is used to connect the unit to the power supply using

the 12V DC power supply provided .

LAN 0, 1, 2, 3

The LAN sockets are used to connect the unit to 10/100-BaseT

LANs using the 2-meter STP (Shielded Twisted Pair) cable

supplied or a suitable alternative. These ports are auto-sensing

for speed and wiring (straight-through or cross-over). To comply

with EMC requirements they should not be used with non-STP

cable.

W-WAN ANT.

(main)

This SMA connector is used to fit the wireless antenna. The

Transport SR-, E and H models are supplied with a single stub

antenna which should be fitted to this connector.

Note: Stub antennas are provided as standard but a range of

suitable alternative for use in different applications may be

purchased separately.

W-WAN ANT.

(aux)

This SMA connector is used on the Transport SR44-U and C

models to fit the second antenna supplied with the unit. The

receiver supports “diversity” antenna capability to improve

performance and are there supplied with two stub antennas. On

models that do not support diversity antennas this connector will

not be present.

Transport SR Series Installation Guide

SERIAL 0, 1

These DB 25 sockets provide synchronous/asynchronous RS232

serial ports which may be used to connect the router to

compatible serial devices. To comply with EMC requirements it

should not be used with a cable longer than 2 meters.

PSTN

This socket is used to connect the router to a PSTN line.

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 while the unit is powered will generate a

hardware reset.

Transport SR Series Installation Guide

2 Installation

All of the products described in this guide are designed for indoor use (office or home).

The system unit should be positioned on a smooth, level surface making sure that there is

adequate ventilation. Do not expose it 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 wireless network if there is a good signal.

For many applications the stub antenna provided will be suitable but in some

circumstances it may be necessary to use a window-mounted or magnetically mounted

antenna with an extended cable to allow the antenna itself to be positioned to provide the

best possible signal reception. Digi International can supply a range of suitable antennas.

Step 1 - Installing the SIM card (GSM models only)

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 at the right side of the front

panel as illustrated below.
