Product Description9Accessory KitA 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 Description10AT Command InfoThis 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 AT Command manuals (onefor GSM/GPRS and one for CDMA). Thesemanuals are available on the MultiTech website or on the Accessory Kit CD.Phone Number for the Wireless Modem· Every wireless modem will have its ownunique phone number.· The wireless modem’s phone number maysimply be told to the subscriber or be on theSIM or both. Wireless providerimplementations may vary.Network AccessThe 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.
Product Description11· For GSM-without-GPRS, a circuit-switched data connection is used. Theuser can set up DUN to make aconventional V.32 modem connection toany terminating modem at the other end.The phone number specified in DUN canbe one supplied by the wireless serviceprovider or another phone numberrelated to a different dialup modemservice (e.g, a dialup modem servicephone number from any commercial orprivate dialup network).· For GSM-with-GPRS, a single DUNnumber is generally used by all of awireless provider’s subscribersthroughout its area of coverage (regional,nationwide, continental, etc.). Rather thanbeing a literal phone directory number, asin conventional DUN, this is a code thatgives the modem Internet access.

Getting Started25Getting Started with yourWireless MultiModemMechanical MountingTo mount the Wireless MultiModem, do thefollowing:1. Obtain mounting screws (two are needed) thatare 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.= 2 mmScrew HeadClearanceSide View
Getting Started26For 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 mmor 41516inchesDrill the mounting holes at the desiredmounting location (if applicable).
Getting Started273. 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.
Getting Started28Electrical Installation & ConfigurationThe wireless MultiModem requires the powersupply connection to begin operation. It alsorequires a SIM card (Subscriber Identity Module) tooperate on a GSM network. To install the modem, dothe following:1. Using your fingernail or a small wedging tool(e.g., a small screwdriver), pry off the SIMcover.
Getting Started292. Insert the SIM card into the holder.
Getting Started303. Verify that the SIM card fits into the holderproperly and then replace the cover.
Getting Started314. Connect a suitable antenna to the SMAconnector (see specifications on page 8).Antenna Connector(SMA type)
Getting Started325. Connect both sides of the serial and controlcable (15-pin Sub D connector on the modemside).Serial & ControlConnectorTo Serial Portof PC
Getting Started336. Plug the power supply cable into the wirelessMultimodem.Power CordIn-LineFusePowerConnectorTo Power Source7. Connect the power supply cable into the powersupply, with a correct GND connection.Connect red wire to + (positive) and black wireto – (negative).Note: For automotive application: according to thetype of application, you can use permanent“+” or key-switched “+”.
Getting Started34Connect the power supply to its source (forexample, in a mobile situation, to the vehicle’sDC fuse/terminal block).8. Activate the power supply.Mobile PhonetoolsFor initial configuration of your wireless device,Multi-Tech offers a Windowsâ based mobilePhone Tools application.To load mobile Phone Tools, click on the mobilePhone Tools icon on your system CD and followthe on screen prompts.
Getting Started35Verifying signal strengthThe Wireless MultiModem establishes a call if thesignal is sufficiently strong. To verify the signalstrength, do the following:1. Using the Hyperterminal program at thecomputer 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:Signal Strength VerificationValue of signal strength(AT+CSQ response)(RSSI)Signal strength11 - 31 sufficient*0 - 10 insufficient*greater than 99 insufficient**Based on general observations.
Getting Started36Verifying network registrationIn 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:Network Registration VerificationValue Network Registration Status0, 1 Yes0, 5 Yes(registered roaming)Note: If the modem is not registered, perform theprocedure for Verifying signal strength onpage 35 to determine the strength of thereceived signal.
