Accessory Kit

A Wireless MultiModem Accessory Kit isavailable. Generally speaking, it is useful tohave one or two kits to configure a group orfleet of Wireless MultiModem units(generally, you will not need one kit for everymodem). The kit includes an antenna, apower supply and a product CD. The productCD contains an AT Command manuals, otherdocumentation, and modem software.

Product Description

10

AT Command Info

This manual describes a minimal set of ATcommands that are adequate for configuringmany common application situations. Acomplete set of AT command definitions canbe found in the CDMA AT CommandsReference Guide. This manual is available onthe MultiTech web site or on the AccessoryKit CD.

Phone Number for the Wireless Modem

Every wireless modem will have its ownunique phone number.

Product Description

11

Network Access

The network access arrangements to bespecified in Windows Dial-Up Networking (ofthe computer that the wireless modem isserving) will vary according to the type ofwireless service used.• For point to point data, a circuit-switched

data connection is used. The user can setup DUN to make a conventional V.32modem connection to any terminatingmodem at the other end. The phonenumber specified in DUN can be onesupplied by the wireless service provideror another phone number related to adifferent dialup modem service (e.g., adialup modem service phone numberfrom any commercial or private dialupnetwork).

• For CDMA 1x data, a single DUN numberis generally used by all of a wirelessprovider’s subscribers throughout its areaof coverage (regional, nationwide,continental, etc.). Rather than being aliteral phone directory number, as inconventional DUN, this is a code thatgives the modem Internet access.

Getting Started with yourWireless MultiModem

Mechanical Mounting

To mount the Wireless MultiModem, do thefollowing:1. Obtain mounting screws (two are needed) that

are appropriate for the surface on which youwill mount the MultiModem. The mountingscrew on the connector end of the unit musthave a screw-head no thicker than 2 mm. Theallowable thickness is limited because thescrew must fit beneath the RS232 cable. Theallowable thickness of the other screw-head isnot limited in this way.

Getting Started

24

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

2. Typically, the unit is mounted against a flatsurface into which holes can be drilled. Themounting holes (center-to-center) must beseparated by 125mm or 4 -15/16 inches.

Screw Separation= 125 mm

or 4 1516 inches

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

3. Slide the mounting bridles into thecorresponding slots on the back side of theMultiModem chassis.

4. Attach the MultiModem with two screws to themounting surface at the desired location on theequipment.

Note: For automotive application: according to thetype of application, you can use permanent“+” or key-switched “+”.

Getting Started

29

Connect the power supply to its source (forexample, in a mobile situation, to the vehicle’sDC fuse/terminal block).

5. Activate the power supply.

For initial configuration of your wireless device,Multi-Tech offers a Windows based mobilePhoneTools application.

To load mobile PhoneTools, click on the mobilePhoneTools icon on your system CD and follow the onscreen prompts.

Verifying signal strength

The Wireless MultiModem establishes a call if thesignal is sufficiently strong. To verify the signalstrength, do the following:1. Using the Hyperterminal program at the

computer to which the Wireless MultiModemis connected, type the AT command AT+CSQ.A value for the received signal strength will bereturned.

2. Verify the result with the following chart:

31

Verifying network registration

In this procedure, you will verify that the WirelessMultiModem has been registered on the wirelessnetwork. To do so, you will use the commoncommunications program Hyperterminal.

1. Using the Hyperterminal program at thecomputer to which the Wireless MultiModemis connected, type the AT commandAT+CREG?. A value for the modem’s networkregistration 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 fixedand mobile applications. “Fixed” means that the device isphysically secured at one location and is not able to beeasily moved to another location. “Mobile” means that thedevice is designed to be used in other than fixed locationsand generally in such a way that a separation distance of atleast 20 cm (8 inches) is normally maintained between thetransmitter’s antenna and the body of the user or nearbypersons. The Modem is not designed for or intended to beused in portable applications (within 20 cm. or 8 in. of thebody of the user) and such uses are strictly prohibited.

Safety

45

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