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.

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 AT Command manuals (one for GSM/GPRS and one for CDMA). These manuals are 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.

· The wireless modem’s phone number may

simply be told to the subscriber or be on the SIM or both. Wireless provider implementations may vary.

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.

Product Description

· For GSM-without-GPRS, 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 GSM-with-GPRS, 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

Side View

Clearance

= 2 mm

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

inches

Drill the mounting holes at the desired mounting location (if applicable).

Getting Started

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.

Getting Started

Electrical Installation & Configuration

The wireless MultiModem requires the power supply connection to begin operation. It also requires a SIM card (Subscriber Identity Module) to operate on a GSM network. To install the modem, do the following:

1. Using your fingernail or a small wedging tool (e.g., a small screwdriver), pry off the SIM cover.

Getting Started

2. Insert the SIM card into the holder.

Getting Started

3. Verify that the SIM card fits into the holder properly and then replace the cover.

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:

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:

Safety

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.

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.

Safety

Vehicl e Safety

· Do not use your Wireless MultiModem while driving, unless

equipped with a correctly installed vehicle kit allowing ‘HandsFree’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
