Product Description

This User Guide describes the MultiModem Wireless EDGE, GPRS, and CDMA modems with an Ethernet
Interface.

Product and Interface Descriptions

Ethernet Interface

The MultiModem wireless modems with an Ethernet interface provide shared Internet access with one IP
address. The built-in routing capabilities provide DHCP services and firewall security using Network Address
Translation. Due to the routing capabilities, these modems are sometimes called routers.

These modems support "always-on" network connection as well as "dial-on-demand" for Internet services. The
"always-on" network connection automatically establishes a wireless data connection and allows for around the
clock surveillance, monitoring or real-time data acquisition of any remote Ethernet device such as a Web
camera. If the data link is dropped in the event of poor reception or a complete loss of service, it will
automatically re-establish the data link. When configured for "dial-on-demand" the wireless modem only
accesses the Internet when data is present. This configuration is ideal for sharing Internet access among
networked PCs.

Software features include remote configuration, firmware upgrade, load configuration screen, and a save
configuration screen.

MultiModem EDGE

The MultiModem® EDGE wireless modem delivers some of the fastest cellular wireless data speeds utilizing
EDGE technology. It allows users to connect to the Internet and send and receive data up to three times faster
than possible with an ordinary GSM/GPRS network making it ideal for highly data-intensive multimedia
applications. The MultiModem EDGE wireless modem is equipped with quad-band GSM, which means it can be
used worldwide on all existing GSM networks.

AT Commands: The MultiModem EDGE wireless modem is configured using the EDGE AT

Commands. These commands are documented in the Reference Guide for the MultiModem
Wireless EDGE Modems, document number S000371x.

Safety Warnings

Ethernet Ports Caution

The Ethernet ports are not designed to be connected to a Public Telecommunication Network.

Handling Precautions

All devices must be handled with certain precautions to avoid damage due to the accumulation of static charge.
Although input protection circuitry has been incorporated into the devices to minimize the effect of this static build
up, proper precautions should be taken to avoid exposure to electrostatic discharge during handling and
mounting.

Safety Recommendations for Rack Installations

• Ensure proper installation in a closed or multi-unit enclosure by following the recommended installation

as defined by the enclosure manufacturer.

• If installing the wireless modem in a closed or multi-unit enclosure, ensure adequate airflow so that the

maximum recommended ambient temperature is not exceeded.

• Do not place the device directly on top of other equipment or place other equipment directly on top of

this device.

• Ensure that the device is properly connected to earth ground via a grounded power cord. If a power

strip is used, ensure that the power strip also provides adequate grounding.

• Ensure that the main supply circuit is capable of handling the load. See the power label on the device

for requirements.

• Maximum ambient temperature is 70 degrees Celsius.

• This device should be installed by properly qualified personnel.

• Only connect like circuits; e.g., connect SELV (Secondary Extra Low Voltage) circuits to SELV circuits

and TN (Telecommunications Network) circuits to TN circuits.

About the Front Panel LEDs

The Ethernet EDGE has 3 Ethernet LEDs and 5 modem LEDs.

Chapter 2 – Getting Started

The Ethernet GPRS has the same LEDs as the EDGE modem and a SIM card slot.

The Ethernet CDMA has the same LEDs as the EDGE modem. It does not, however, have a
SIM card slot.

Ethernet LEDs

IP IP FUNCTION. This LED blinks when the IP function of the modem/router is operating normally. It shows a

steady light when powering-up, initializing, or flashing the firmware.

SPD SPEED. This LED lights when the Ethernet is linked at 100 Mbps. If it is not lit, the Ethernet is linked at 10

Mbps.

L/A LINK ACTIVITY. This LED blinks when there is transmit and receive activity on the Ethernet. It shows a

steady light when there is a valid Ethernet connection.

Modem LEDs

TD TRANSMIT DATA. This LED blinks when the modem is transmitting data to your wireless carrier.
RD RECEIVE DATA. This LED blinks when the modem is receiving data from your wireless carrier.
CD CARRIER DETECT. This LED lights when the modem detects a valid carrier signal from a wireless carrier.
TR (DATA) TERMINAL READY. This LED lights when the modem is trying to establish a wireless connection.
LS LINK STATUS. This LED blinks when there is a valid wireless signal. When it is on or off, the wireless

strength is low.

Test Your Workstation

Test your workstation to see that it can access the Internet. If a connection is established, then the settings have
been entered correctly. Note: If you had changed your IP Address, be sure to enter the new one when you access
the Internet.

Set Time and Date

The date and time must be set using the Web Management software.
The time and date set in IP Setup will not be correct unless SNTP client is enabled and you have a live Internet
connection. See SNTP client.

Shutdown Caution

Never unplug the power until after you have performed the Save & Reset process. If the setup changes are not
properly saved before unplugging the power, data could be lost.

Multi-Tech Systems, Inc. MultiModem Wireless Modem with Ethernet Interface (S000375A) 12

Chapter 2 – Getting Started

Using AT Commands

Important Note: Before you can use these commands, you must complete Steps 4.1 through 4.4 on page 9.

Query Your Modem's Operation

1. Check the signal quality.

• Type AT+CSQ

Modem responds with the received signal strength (rssi).

2. Check the identity of the modem.

Use command: ATI (AT is followed by the capital letter i).

• Type ATI0 (The command ends in a zero).

Manufacturing data displays: Wavecom Modem 800 1900

• Type ATI3

Software version displays. Ex: S/W VER: xxxxx

• Type ATI6

Capability data displays. Ex: +CGSM, +CIS707, ...

3. Check the network registration and roaming status.

• Type AT+CREG?

The modem will respond in one of the following ways:

+CREG: 0,0 (this tells you the modem is not registered on any network)
+CREG: 0,1 (this tells you the modem is registered on the home network)

Set Up a Circuit-Switched Data (CSD) Connection for
CDMA and GSM

+CREG: 0,5 (this tells you the modem is registered on a network but it is roaming)

A Circuit-Switched Data Connection makes the wireless modem work like a regular analog modem. You
must have CSD service in order to make a CSD call.

1. Establish a Connection: Using HyperTerminal or a terminal application, establish a CSD connection

by entering command: ATD<phone number>

Notes:

• The phone number you are calling is entered between the displayed brackets. Do not type

additional brackets. Ex: type only ATD 8585551212 between brackets.

• This command tells the modem to inform the wireless network that you are initiating a CSD modem

call. If you are dialing to another modem, the remote modem should answer and a connection
between the two modems will be established. If you include a semi-colon (;) at the end of the

2.

dialing string, the modem will instead initiate a Voice call to the phone number dialed.

Disconnect: Use the following commands:

+++ Wait about 2 seconds to see OK.
Then type: ATH

Note: +++ is the escape sequence and ATH is the Hang-up command.

Answering a Circuit-Switched Data (CSD) Connection

A Circuit-Switched Data Connection makes the wireless modem work like a regular analog modem. You
must have CSD service in order to answer a CSD call.

For CDMA

Establish A Connection:

Using HyperTerminal or a terminal application, enter the following command:
AT+CICB=0 <cr> This sets the modem to answer in data mode.
Then call into the modem by dialing the number provided by your carrier.

Answer a Call: Enter ATA <cr> when you see on the terminal screen that RING responses are

coming through.

Set Auto-Answer: Enter ATS0=x (where x is the number of rings). This sets the modem to auto-

answer. The call is answered after x number of rings.

Call into the modem by dialing the number provided to you by the carrier.

Disconnect: Use the following commands:

+++ Wait about 2 seconds for OK.
Then type: ATH

For GSM

There are three phone numbers for GSM: the voice number, the data number, and the fax number.
All are provided by the carrier. To answer a call:

Establish A Connection:

Call into the modem by dialing the data number provided by your carrier.

Answer a Call: When you see the RING responses on the terminal screen, enter ATA <cr> to

answer the call.

Set Auto-Answer: Enter ATS0=x (where x is the number of rings). This sets the modem to auto-

answer. The call is answered after x number of rings.

Then call into the number provided to you by the carrier.

Disconnect: Use the following commands:

+++ Wait about one second to see OK.

Chapter 4 – Wireless Antenna

The Antenna

The antenna sub-system and integration in the application is a major issue: Choice of antenna (type, length,
performances, thermal resistance, etc.) These elements could affect GSM performances such as sensitivity and
emitted power.

GSM and CDMA Antenna

The integrated modem antenna connector is a SMA connector. The SMA connector incorporates a 'Screw-on'
action in order to make the connection easier while providing an excellent RF performance. An additional
advantage is its small physical size, which is 50% of the standard MCX connector.
This type of connector is suitable for the standard ranges of flexible and semi-rigid cables. The characteristic
impedance of the MMCX coaxial connector is 50 ohm. The antenna manufacturer must guarantee that the
antenna will be working according to the radio characteristics presented in the table below.

Appendix C – Waste Electrical and Electronic Equipment

Appendix C – Waste Electrical and

Electronic Equipment

July, 2005

Waste Electrical and Electronic Equipment (WEEE)

The WEEE directive places an obligation on EU-based manufacturers, distributors, retailers and importers to take­back electronics products at the end of their useful life. A sister Directive, ROHS (Restriction of Hazardous
Substances) complements the WEEE Directive by banning the presence of specific hazardous substances in the
products at the design phase. The WEEE Directive covers all Multi-Tech products imported into the EU as of August
13, 2005. EU-based manufacturers, distributors, retailers and importers are obliged to finance the costs of recovery
from municipal collection points, reuse, and recycling of specified percentages per the WEEE requirements.

Instructions for Disposal of WEEE by Users in the European Union

The symbol shown below is on the product or on its packaging, which indicates that this product must not be
disposed of with other waste. Instead, it is the user’s responsibility to dispose of their waste equipment by handing it
over to a designated collection point for the recycling of waste electrical and electronic equipment. The separate
collection and recycling of your waste equipment at the time of disposal will help to conserve natural resources and
ensure that it is recycled in a manner that protects human health and the environment. For more information about
where you can drop off your waste equipment for recycling, please contact your local city office, your household
waste disposal service or where you purchased the product.
