Product Description

Accessory Kit

A Wireless MultiModem Accessory Kit is available. Generally speaking, it is useful to have one or two kits to configure a group or fleet of Wireless MultiModem units

(generally, you will not need one kit for every modem). The kit includes an antenna, a power supply and a product CD. The product

CD contains an AT Command manuals, other documentation, and modem software.

9

Product Description

AT Command Info

This manual describes a minimal set of AT commands that are adequate for configuring many common application situations. A complete set of AT command definitions can be found in the CDMA AT Commands

Reference Guide. This manual is available on the MultiTech web site or on the Accessory

Kit CD.

Phone Number for the Wireless Modem

Every wireless modem will have its own unique phone number.

10

Product Description

Network Access

The network access arrangements to be specified in Windows Dial-Up Networking (of the computer that the wireless modem is serving) will vary according to the type of wireless service used.

•

For point to point data, a circuit-switched data connection is used. The user can set up DUN to make a conventional V.32

modem connection to any terminating modem at the other end. The phone

• number specified in DUN can be one supplied by the wireless service provider or another phone number related to a different dialup modem service (e.g., a dialup modem service phone number from any commercial or private dialup network).

For CDMA 1x data, a single DUN number is generally used by all of a wireless provider’s subscribers throughout its area of coverage (regional, nationwide, continental, etc.). Rather than being a literal phone directory number, as in conventional DUN, this is a code that gives the modem Internet access.

Getting Started

Getting Started with your

Wireless MultiModem

Mechanical Mounting

To mount the Wireless MultiModem, do the following:

1. Obtain mounting screws (two are needed) that are appropriate for the surface on which you will mount the MultiModem. The mounting screw on the connector end of the unit must have a screw-head no thicker than 2 mm. The allowable thickness is limited because the screw must fit beneath the RS232 cable. The allowable thickness of the other screw-head is not limited in this way.

Screw Head

Clearance

= 2 mm

Side View

23

Getting Started

For example, one might use two 6-32 selftapping screws 5/8” in length to mount the unit in a truck to the wall of the cab behind the passenger’s seat.

2. Typically, the unit is mounted against a flat surface into which holes can be drilled. The mounting holes (center-to-center) must be separated by 125mm or 4 -15/16 inches.

Screw Separation

= 125 mm or 4

3. Slide the mounting bridles into the corresponding slots on the back side of the

MultiModem chassis.

4. Attach the MultiModem with two screws to the mounting surface at the desired location on the equipment.

25

29

Getting Started

Verifying signal strength

The Wireless MultiModem establishes a call if the signal is sufficiently strong. To verify the signal strength, do the following:

1. Using the

Hyperterminal

program at the computer to which the Wireless MultiModem is connected, type the AT command AT+CSQ.

A value for the received signal strength will be returned.

2. Verify the result with the following chart:

Getting Started

Verifying network registration

In this procedure, you will verify that the Wireless

MultiModem has been registered on the wireless network. To do so, you will use the common communications program

Hyperterminal

.

1. Using the

Hyperterminal

program at the computer to which the Wireless MultiModem is connected, type the AT command

AT+CREG?. A value for the modem’s network registration status will be returned.

2. Verify the result with the following chart:

General Safety

The modem is designed for and intended to be used in fixed and mobile applications. “Fixed” means that the device is physically secured at one location and is not able to be easily moved to another location. “Mobile” means that the device is designed to be used in other than fixed locations and generally in such a way that a separation distance of at least 20 cm (8 inches) is normally maintained between the transmitter’s antenna and the body of the user or nearby persons. The Modem is not designed for or intended to be used in portable applications (within 20 cm. or 8 in. of the body of the user) and such uses are strictly prohibited.

44

Safety

It is important to follow any special regulations regarding the use of radio equipment due in particular to the possibility of radio frequency, RF, interference. Please follow the safety advice given below carefully.

•

Switch OFF your Wireless MultiModem when in an aircraft.

The use of cellular telephones in an aircraft may endanger the operation of the aircraft, disrupt the cellular network and is illegal. Failure to observe this instruction may lead to suspension or denial of cellular telephone services to the offender, or legal action or both.

•

Switch OFF your Wireless MultiModem when around gasoline or diesel-fuel pumps and before filling your vehicle with fuel.

•

Switch OFF your Wireless MultiModem in hospitals and any other place where medical equipment may be in use.

•

Respect restrictions on the use of radio equipment in fuel depots, chemical plants or where blasting operations are in progress.

•

There may be a hazard associated with the operation of your

Wireless MultiModem close to inadequately protected personal medical devices such as hearing aids and pacemakers. Consult the manufacturers of the medical device to determine if it is adequately protected.

•

Operation of your Wireless MultiModem close to other electronic equipment may also cause interference if the equipment is inadequately protected. Observe any warning signs and manufacturers’ recommendations.

45

Safety

Vehicle Safety

•

Do not use your Wireless MultiModem while driving, unless equipped with a correctly installed vehicle kit allowing ‘Hands-

Free’Operation.

•

Respect national regulations on the use of cellular telephones in vehicles. Road safety always comes first.

•

If incorrectly installed in a vehicle, the operation of Wireless

MultiModem telephone could interfere with the correct functioning of vehicle electronics. To avoid such problems, be sure that the installation has been performed by qualified personnel. Verification of the protection of vehicle electronics should be part of the installation.

•

The use of an alert device to operate a vehicle’s lights or horn on public roads is not permitted.

Maintenance of Your Modem

•

Do not expose the Wireless MultiModem to any extreme environment where the temperature or humidity is high.

•

Do not attempt to disassemble the Wireless MultiModem. There are no user serviceable parts inside.

46

Safety

•

Do not expose the Wireless MultiModem to water, rain or spilt beverages. It is not waterproof.

•

Do not abuse your Wireless MultiModem by dropping, knocking, or violently shaking it. Rough handling can damage it.

•

Do not place the Wireless MultiModem alongside computer discs, credit or travel cards, or other magnetic media. The information contained on discs or cards may be affected by the phone.

•

The use of accessories not authorized by Multi-Tech or not compliant with Multi-Tech’s accessory specifications may invalidate the warranty of the Wireless MultiModem.
