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 f or 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

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 thicke r than 2 mm. The
allowable thickness is limited because the
screw must fit beneath t he RS232 cable. The
allowable thickness of the other screw-head is
not limited in this way.

Screw Head

Clearance

= 2 mm

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 inc hes.

Getting Started

Verifying signal strength

The Wireless MultiModem establishes a call if the
signal is sufficientl y 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 plan t s 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 ai ds and pacemakers. Consult
the manufacturers of the medical device t o 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.
