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.

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
S
Every wireless modem will have its own
unique phone number.
S
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-
S
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).
S
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
Clearance
= 2 mm

Getting Started
For example, one might use two 6-32 self-
tapping 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 415 inches

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

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

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.

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:
