This manual covers the operation of the CalAmp SMC-CDMA Embedded Wireless Modem.
Specifications described are typical only and are subject to normal manufacturing and
service tolerances.

CalAmp reserves the right to modify the equipment, its specification or this manual without
prior notice, in the interest of improving performance, reliability or servicing. At the time of
publication all data is correct for the operation of the equipment at the voltage and/or
temperature referred to. Performance data indicates typical values related to the particular
product.

Modem Design Considerations

The suppression of noise, both coupled and radiated, by the OEM board design is essential
to ensure proper operation of the SMC-CDMA modem on any provider’s cellular network.
Proper PC board layout and design guidelines should be considered to ensure the end device
passes required electromagnetic interference (EMI) specifications and does not impede the
performance of the SMC-CDMA modem when operating on the cellular network. The
following guidelines can be used to help minimize generated EMI from the OEM main board
containing the SMC-CDMA modem.

Provide a good ground plane. If a multilayer board can be used, use one full layer

each for ground and power distribution.

Any high frequency signals should be kept as short as possible, these circuits should

be located in a separate area of the board and isolated, with shielding and ground
plane, from connectors, cables, and the SMC-CDMA modem to minimize coupling.

Keep DC power decoupling capacitors as close to the SMC-CDMA modem as possible.

Other layout techniques may be required to properly isolate unwanted interference for a
specific application. Please consult other engineering publications or contact our technical
service department.

NOTE: For OEM customers using the Sprint network; the SMC-CDMA modem has been
certified with a specific modem and antenna configuration. If this configuration is changed
in any way, the final device would have to go through the Sprint certification process. To
enter the Sprint certification process please send an email to
[e-mail].

Modem Use

The SMC-CDMA modem is designed and intended for use in fixed and mobile applications.
―Fixed‖ assumes the device is physically secured at one location and not easily moved to
another location. Please keep the cellular antenna of the SMC-CDMA at a safe distance from
your head and body while the modem is in use (see below).

Important

Maintain a distance of at least 20 cm (8 inches) between the transmitter’s antenna and any
person while in use. This modem is designed for use in applications that observe the 20 cm
separation distance.

Interference Issues

Avoid possible radio frequency (RF) interference by following these guidelines:

The use of cellular telephones or devices in aircraft is illegal. Use in aircraft may

endanger operation and disrupt the cellular network. Failure to observe this
restriction may result in suspension or denial of cellular services to the offender,
legal action or both.

Do not operate in the vicinity of gasoline or diesel-fuel pumps unless use has been

approved and authorized.

Do not operate in locations where medical equipment that the device could interfere

with may be in use.

Do not operate in fuel depots, chemical plants, or blasting areas unless use has been

approved and authorized.

Use care if operating in the vicinity of protected personal medical devices, i.e.,

hearing aids and pacemakers.

Operation in the presence of other electronic equipment may cause interference if

equipment is incorrectly protected. Follow recommendations for installation from
equipment manufacturers.

Mobile Application Safety

Do not change parameters or perform other maintenance of the SMC-CDMA while

driving.

Road safety is crucial. Observe National Regulations for cellular telephones and

devices in vehicles.

Avoid potential interference with vehicle electronics by correctly installing the

SMC-CDMA. CalAmp recommends installation by a professional.

Verify SMC Modem Connectivity

Power on the SMC test board (+12VDC typical), then start HyperTerminal.

Figure 5.2 HyperTerminal screen responses

The ATI command prints the cell module product information. If you get an Error or no
communication, verify the modem is connected to the proper COM port and powered on. Refer to
Figure 5.2 for all the AT commands listed below.

Verify the modems Mobile Equipment Identity (MEID) number with the AT+CGSN (for Decimal
number) or AT+GSN (for Hexadecimal number) command. The MEID number replaces the ESN
(Electronic Serial number).

Verify good signal strength with the AT+CSQ? command. A typical reply is +CSQ: 16, 99, using the
mag-mount antenna indoors. The first number is signal strength and ranges from 0 to 31 (the higher
the number, the stronger the signal).

Confirm the phone number currently in the modem with the AT$SPMDN? command. If the unit is
not provisioned, the number should be 10 digits beginning with several zeros, i.e. 0000005972.

Exit HyperTerminal before attempting to connect using a Dial-Up-Networking connection.

OMA-DM SPRINT

Sprint provides customer functionality and miscellaneous services that will utilize "server-initiated"
OMA DM sessions. These services include, but are not limited to, firmware updates, PRL updates,
and application downloads, etc.

The OMA-DM sessions can be initiated by the network (NI) or by the Client (CI).

Sprint requires that OMA-DM runs in profile 0, and other data sessions run in profile 1. Other data
sessions are restricted when OMA is in progress such as DUN, TCPIP etc.

HFA (Hands-Free Activation) – is basically a CIDC session that is automatically triggered by the
device. A Hands-Free Activation session is only triggered for initial activation on the first power-up,
or on the first power-up after being refurbished (Master Reset: +MMR).

HFA retries - If the device connects to the OMA-DM server and no profile information is available, the
device will pause for 60 seconds and retry up to 5 times. The device will retry only when successfully
connecting to the server and no profile information is available. The device will not retry when an
error occurs during the connection or the session with the server.

NIDC/NIPRL/NIFUMO – Only in the case of network initiated OMA-DM, if the session establishment
fails due to a network problem, the OMA-DM Client will attempt to re-establish the session every 1
minute until the DM session is successful or until it retries 5 times.

Verifying a Hands Free Activation

Once an account has been established for the SMC-CDMA-SPN modem, the OMA-DM provisioning
can occur. To start a Hands-Free activation using the SMC Test Board, follow these steps.

1. Establish a HyperTerminal session with the SMC-CDMA-SPN modem.

2. Type AT+MMR to re-set the modem to factory defaults and allow the automatic CIDC

session to start when the modem is powered up again.

3. Power up the SMA-CDMA-SPN modem and type AT+MODIND=1 to enable the OMA-DM

unsolicited informational report lines to be displayed on the HyperTerminal screen.

+MODIND: 5, indicates the HFA has started.
+MODIND: 7, indicates the Device Configuration (DC) is updating.
+MODIND 14, indicates the HFA update is complete. At this point the SMC-CDMA-SPN

modem should be provisioned on the network.

+MODIND 18, indicates the Network Initiated OMA-DM session is complete.

Type the AT$SPMDN? command to verify the correct phone number was programmed in the unit.

Page 16 of 62

001-0004-819 Rev01

Verify Activation using HyperTerminal

With the provisioned SMC-CDMA modem installed, power on the SMC test board (+12VDC typical)
and start HyperTerminal as described in Section 5.

Type the AT+MIPCALL=1 command to start a PPP connection with the carrier network.

If the module is provisioned properly, an IP address will be assigned.

Type AT+MPING=1,”www.google.com”. This will ping the Google server and send back the ping
statistics.

Typing AT+MPCALL=0 will terminate the PPP connection. Refer to Figure 6.1 below.

Figure 6.1: HyperTerminal MIPCALL example

001-0004-819 Rev01

Verify Activation using a Dial-Up-Network Connection

A Windows Dial-up network connection can be used to verify carrier activation on the network.
Create a dial-up network connection using a standard modem set to 115200 bps. Go to the Network
Connections screen and double click on the Dial-Up connection (example: SMC-CDMA).

When the connect window appears, set the username and password as defined for your carrier
(usually blank). Enter the phone number as #777 and click the Dial button.

The modem will attempt to connect to the provider network. If the configured baud rate for the COM
port, the modem, and the DUN do not match, the DUN will not be able to talk to the modem
properly and you will get a hardware error message. Otherwise the DUN will contact the cellular
network and authenticate the user on the network.

Once connected you should be able to browse the internet thorough the DUN session. To confirm
this, disable any other network connections you may have running.
