Model DCP-NextG Digital Cell Phone Kit Model DCP-NextG Digital Cell Phone Kit 1 Network Coverage One of the main advantages of using a cellular telephone network is being able to set up a communications link to a data logger virtually anywhere without installing telephone lines. However, this only applies if your installation site is covered by a suitable NextG network.
Model DCP-NextG Digital Cell Phone Kit 3 Getting Connected – Circuit Switched Data The NextG modem is sold without an airtime agreement. The user must arrange connection of the modem to a network and have it enabled for data use. The service provider will supply a Subscriber Identification Module (SIM), which is inserted into the SAM3G+ and acts as a key to enable its use. When setting up the account, the service provider may require some information such as the make and model of the modem being used.
Model DCP-NextG Digital Cell Phone Kit 4 Modem Overview USB Connector for Antenna RS-232/Power RJ45 Connector Status LED Figure 4-1 SAM3G+ MODEM The SAM3G+ modem has two communication interfaces – USB and RS-232. The USB interface is only used in conjunction with Intercel’s PC software and will not be discussed here. Note that USB and RS-232 should never be connected simultaneously as both interfaces provide power to the modem. The RS-232 interface is used to connect the modem to a data logger.
Model DCP-NextG Digital Cell Phone Kit 5.2 Datalogger I/O Ports The following is a table of 9-pin ports available on Campbell Scientific data loggers.

Model DCP-NextG Digital Cell Phone Kit To connect a new CS I/O modem kit to a data logger, follow these steps: Connect the black DCP-SAM3GPLUS-CBL’s square RJ45 connector to the socket on the modem. Connect the two tinned wires on this cable to the data logger. The red wire connects to 12V and the black wire to the G terminal. The SW12 terminal can be used instead of 12V however since it is a switched supply it needs to be enabled in the datalogger program to function correctly.
Model DCP-NextG Digital Cell Phone Kit 5.3.1 SC105 Interface In order to connect via the CS I/O port of the data logger a serial interface is required. Generally a SC932A RS-232 interface is supplied, however in some cases the alternate SC105 RS-232 interface may be used due to the customer preference or the requirements of the system.
Model DCP-NextG Digital Cell Phone Kit Figure 5-3 SC105 Deployment Configuration In the Deployment tab, select the following settings: Field Value CS I/O Mode Modem Enable CS I/O Baud Rate 115.2k RS-232 Mode PC/PDA Baud Rate 115.2k Table 5-3 SC105 Configuration Settings Once this is done, click Apply. Connect to the SC105 again and select the Settings Editor Tab. Change the RS-232 Auto Power Down setting to “RS-232 Always Active to power RS-232 devices” and click Apply again.
Model DCP-NextG Digital Cell Phone Kit To access the menus using Hyperterminal, establish a connection between the serial port and the SC105 using the null-modem cable (included with the SC105). The port settings for this connection should be 9600-8-N-1. Press the green programming button on the side of the SC105 and the menus will appear in the terminal window.

Model DCP-NextG Digital Cell Phone Kit 6 Power Considerations 6.1 Current Requirements Because of the transmitting current drain of the Intercel SAM 3G+, the length and frequency of both incoming and outgoing calls should be considered when determining the best power supply for your system: o Where pre-determined call intervals are short and infrequent (e.g.
Model DCP-NextG Digital Cell Phone Kit 7 SAM3G+ Configuration 7.1 Hardware As discussed above, the modem can be powered in a number of ways. The power supply wires can be connected directly to battery terminals, to the logger 12V or SW12V supplies or to some external relay circuit. If the modem is to be switched on and off via a relay or the SW12V supply of a data logger, the control of switching the power supply on and off can be performed by the user program in the data logger.
Model DCP-NextG Digital Cell Phone Kit 7.2 Software 7.2.1 SAM 3G+ Settings Like most phone modems, the Intercel SAM3G+ has a large number of commands and settings. These settings allow the modem to be configured in many different ways. Modems purchased from Campbell Scientific will be pre-configured with the correct settings to interface with our CR800,CR1000 and CR3000 data loggers. Some configuration will be necessary for correct use with our CR200X, CR510X, CR10X and CR23X loggers.
Model DCP-NextG Digital Cell Phone Kit Alternatively, you can use terminal emulation software such as PuTTY, Hyperterminal or some other PC terminal emulator. Your chosen software can then be used to set the necessary parameters. Figure 7-2 PuTTY Connection to SAM3G+ Terminal Emulator settings should be: Baud Rate: 115200bps Data Bits: 8 Stop Bits: 1 Parity: None Flow Control: None Type AT followed by Enter and OK should be returned.
Model DCP-NextG Digital Cell Phone Kit +IPR=9600 : Baud Rate control. The CR200, and Array-based data loggers, such as the CR510 and CR10X, are limited to 9600 baud communications. This command limits the terminal communications speed to 9600 baud from its default of 115200. The response to this command may not be visible as it may be returned at 9600 baud while the terminal emulator is set to 115200.
Model DCP-NextG Digital Cell Phone Kit 8 SMS This section is for users who write their own datalogger programs. SMS is a function available in many of the modems on the market today. It is a feature of the SAM3G+. When used with a datalogger, SMS can be a useful tool for alarming, and/or for controlling the datalogger remotely. Each modem has a range of commands used to send an SMS and to check, read, and delete messages received.
Model DCP-NextG Digital Cell Phone Kit 8.1 Example Program The following program example sends a single SMS, when the temperature of a thermocouple exceeds 30 degrees celcius.

Model DCP-NextG Digital Cell Phone Kit 10 Troubleshooting There are many steps involved in getting your phone modem ready for use and each step must be completed before the unit can be used. Please use the following points to check that you have the correct setup. Do you have the wiring correct? A common fault is to have the SC932A adapter around the wrong way. Please check your wiring against the figure 4.1 in section 4. The gender of these devices allows connection in reverse.
