Page 12: Development/Test Board Interface
Development/Test board The Development/Test board is required to interface the SCM-GPRS modem to a standard RS232 serial connection. The SMC test board also supplies the SMC-GPRS modem with the required +5VDC supply voltage from an externally supplied 10 to 28 VDC power source, +12VDC typical.

Page 14: Getting Started Using The Smc Test Board
This section describes the use of the SMC test board to set up the SMC modem for internet access using HyperTerminal and a dial-up network connection (DUN). Please refer to Appendix B for details on setting up a modem driver for a DUN connection. Connecting Up the SMC Test Board Connect the Power cable, RS232 cable, Antenna cable to the SMC test board as shown in Figure 5.1. -
Page 15: Verify Smc Modem Connectivity
Verify SMC Modem Connectivity Power on the SMC test board (+12VDC typical) and observe the HyperTerminal window for ^SYSSTART , indicating the SMC modem successfully powered on. 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. -
Page 16: Define The Packet Data Protocol (Pdp) Context
Confirm that the SIM‘s PIN has been authenticated by the network using the AT+CPIN? command. The reply should read ―+CPIN: READY‖. See Section 6 for SIM related information if ―READY‖ does not display. Verify good signal strength with the AT+CSQ command. A typical reply is +CSQ 25, 99. The first number is signal strength and ranges from 0 to 31 (the higher the number, the stronger the signal). -
Page 17: Connect Using The Dial-Up-Network Connection
Connect using the Dial-Up-Network Connection Go to the Network Connections screen and double click on the newly created Dial-Up connection (i.e. SMC-GPRS). When the connect window appears, set the username and password as defined for your carrier (usually blank). Enter the phone number as *99***1# and click the Dial button. 001-0004-829 Rev01 Page 17 of 73... - Page 18 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.
- Page 19 Right click on the connected Dial-Up connection icon in the task bar and select the Details tab. The status of the connection will be displayed, including the IP address assigned by the carrier network. 001-0004-829 Rev01 Page 19 of 73...

Page 20: Sim Card Specific Information
The SIM card can be used to store a Personal Idetification Number (PIN) to authenticate users on the network. The AT+CPIN write command can be used to enter one of the passwords listed below. The read command can be used to check whether or not the ME is waiting for a password, or which type of password is required. -
Page 21: What To Do If Pin Or Password Authentication Fails
What to do if PIN or password authentication fails? PIN1 / PUK1: After three failures to enter PIN 1, the SIM card is blocked (except for emergency calls). +CME ERROR: 12 will prompt the client to unblock the SIM card by entering the associated PUK (= PIN Unblocking Key / Personal Unblocking Key). - Page 22 SIM locks: These are factory set locks, such as "PF", "PN", "PU", "PP", "PC". An 8-digit unlocking code is required to operate the mobile with a different SIM card, or to lift the lock. The code can only be obtained from the provider. Failure to enter the password is subject to the same timing algorithm as the Master Phone Code (see Table above).

Page 23: Call Setup Information
This section provides a brief look at setting up variuos call scienerios using the SMC-GPRS modem with the SMC Development/Test board and HyperTerminal. In general, each call scienerio requires a set of initialization commands to set up the SMC modem for the specific call type. See related documents [1] and [2] for more detailed descriptions and examples for all call types. -
Page 24: Csd Incoming Calls
Select ATV0 to set the short format (numeric code) or ATV1 to set the long format (verbose code) of result codes. In case of using the command without parameter the value will be set to 0. Generally, only AT+CBST=0 (auto bauding) and AT+CBST = 7 (9600 bps, [V.110]) are supported and provide reliable performance. -
Page 25: General Packet Radio Service (Gprs)
General Packet Radio Service (GPRS) Before proceeding, be sure the cellular account SIM is provisioned with GPRS data services and all necessary initialization commands have been executed. The module must then be attached to the GPRS service, allowing the device to be accessable by the network, but no data transmission is yet possible. -
Page 26: Define The Gprs Context
Define the GPRS Context Exact settings of GPRS context and Quality of Service Profiles are provisioned by the network provider and must be requested before defining the GPRS context. Every PDP context has a context identifier <cid>. The context identifiers are numbered sequentially and have to start with value 1. -
Page 27: Short Message Service (Sms)
Short Message Service (SMS) SMS is a service to transfer short messages between a GSM Mobile Stations (MS) and an Short- Message-Entity (SME) via a Service Center (SC). SMC modems support two modes: text mode and Protocal Data Unit (PDU) mode. The minimal requirements to send a short message are: - Service center address of the provider - Destination address - Content of the message... -
Page 28: Writing Sms
If you want to receive cell broadcast messages activate the URC presentation for CBS with AT+CNMI and subscribe to a CBS channel with AT+CSCB. The AT^SM20 command specifies different modes of responses returned when sending and writing short messages: AT^SM20=,0 causes the ME return "+CMS ERROR: <err>" when writing or sending of short messages fails. -
Page 29: Internet Services
Internet Services The modem has an embedded TCP/IP stack that is driven by AT commands and enables the host application to easily access the Internet. The advantage of this solution is that it eliminates the need for the application manufacturer to implement their own TCP/IP and PPP stacks, thus minimizing cost and time to integrate Internet connectivity into a new or existing host application. - Page 30 The TCP/IP stack of TC63i supports using several service profiles at the same time, provided all of them are running on the same connection profile. For example, it is possible to download files from an FTP server, while sending and receiving emails at the same time. GPRS connections established over the Dial-Up Network do not use the embedded TCP/IP stack of TC63i and can be active at the same time.

Page 31: Smc Modem Module Profiles
In addition to the default profile, you can store an individual one with AT&W. To alternate between the two profiles enter either ATZ (loads user profile) or AT&F (restores factory profile). NOTE: Every ongoing or incoming call will be terminated. Table 8.1: Profile Commands Returns the current parameter setting. -

Product Warranty, RMA and Contact Information CalAmp guarantees that every SMC-GPRS Cellular Modem will be free from physical defects in material and workmanship for one (1) year from the date of purchase when used within the limits set forth in the Specifications section of this manual. The manufacturer's warranty statement is available in Appendix 1. -
Page 58: Power Supply Issues
– – Power Supply Issues Because of its high current consumption during transmission, power supply design for the SMC-GPRS modem should be focused on the transmitting mode (dedicated mode). More information can be found in related document [3]. Power Consumption for GSM/GPRS Cell Module Due to the maximum RF power levels of approx. -
Page 59: Smc-Gprs Power Supply Requirements
Power Losses and Voltage Drops for GSM/GPRS Cell Module The cell modules are specified to operate with specific voltage supplies. Voltage supplies may range from 3.2V to 4.5V as measured on the module‘s power connector. To be on the safe side, it should be assumed that the voltage drop during the TX burst does not exceed 400mV. - Page 60 SMC-GPRS Power Supply Considerations Ideally, the external 5VDC supply should be able to provide the 1.4A current required by the SMC- GPRS modem when the TX bursts occur. When this is not a practical design alternative, a mix between a linear regulator and capacitor supply may be an alternative approach. Figure 3 shows the basic block diagram.
