B the system will be disabled until the next sequence occurs e Ifthe Fastrack fails to unlock the PIN code for whatever reason three times in a row the SIM card will be permanently locked This will require you to contact your airtime service provider to provide an unlock code for the SIM A1 Introduction To operate with the Fastrack s PIN feature enabled the datalogger must transmit the command to send the PIN to the Fastrack after turning on the power For CRBasic dataloggers this is simply done by using serial commands to send the PIN code after the modem is turned on see the example below For Edlog dataloggers this is done using Instruction P97 Initiate Telecommunications using the Generic Modem option This option has only been added in recent releases of the CR510 CR10X and CR23X operating systems from versions 1 06 1 13 and 1 10 and later respectively If you have one of these dataloggers with an older operating system you should contact Campbell Scientific to arrange an upgrade Users of older dataloggers e g the 21X CR10 or CR7 should contact Campbell Scientific to obtain a copy of a manual written for early versions of the M20T which describes an alternative but more complicated way of sending PIN codes using special cables and Instruction P98 Send Character A2 CRBasic Program Example This example can be used on the CR800 series CR1000 and CR3000 dataloggers It uses the standar
4. CS GPRS package 1 Introduction The CS GSM kits use the Sierra Wireless Wavecom Fastrack Xtend module that is designed to allow transfer of data across a GSM Global System for Mobile communications digital cellular phone network The Fastrack is a GSM digital transceiver it can be thought of as a GSM phone module without a handset but which has an extra interface to allow data devices to be connected It has the following features e Standard RS232 serial port e Relatively low power consumption e Wide operating temperature range 30 C to 75 C e Can be used to collect data from a datalogger at a similar speed to a land based 9600 baud modem in good reception areas e Closely emulates a standard Hayes style telephone modem suitable for situations where the datalogger instigates a call back to a base station e g for alarm purposes e Compact package 89x60x30mm subject to change The CS GSM kits include all the cables and antenna to allow easy use with Campbell Scientific dataloggers CS GSM Digital Transceiver Kits 2 Quick Start Guide If you purchased the standard CS GSM kit you will have been supplied with a Fastrack module SC WMI logger interface plus SC12 cable mounting bracket and an aerial The CS GSM232 kit includes a special RS232 cable instead of the SC WMI interface and SC12 For either kit the module is preconfigured so that it should work out of the box This section of the manual g
5. In areas of poor signal coverage a directional high gain Yagi antenna can be considered but this requires knowledge of where the cell base stations are situated in order to enable proper alignment e Raising the antenna is often the most effective way of getting better signal reception However if long cables are required to achieve this use low loss extension cables that do not have the significant signal loss of low cost cables Long cables are a particular problem when operating at 1800MHz e Like most cellular based systems the Fastrack varies its transmitter power to ensure good communications with the remote cell station Using a cheaper low gain antenna may result in a significant increase in power consumption in areas of poor signal coverage e Ifthe antenna is placed near the top of a mast it may be vulnerable to lightning damage If lightning is common at the installation site additional lightning protection may be required to protect the Fastrack please contact Campbell Scientific for further advice Using an antenna that is installed incorrectly or with faulty wiring can lead to premature failure of the transmitter output of the Fastrack Install the antenna so that the radiator is positioned away from other vertical metal structures It should also be at a distance from any sensors so that it does not either physically or electrically interfere with the sensor readings If the Fastrack is connected to a PC se

8. logged off the network preventing new incoming calls The reasons this can happen are that the network may miss the regular I am here messages that the Fastrack transmits every few seconds or in some cases the network will timeout the registration due to inactivity The exact algorithm used to decide whether to deregister a phone varies from network to network Problems are more likely where the connection is marginal or where the local cell is congested To help overcome these problems the datalogger can be programmed to either reset the Fastrack by sending it commands see Appendix E or to shut down the Fastrack at regular intervals using a power switch as described in Appendix B This will save power but also ensures that the Fastrack is reset into a known state and to make it re register itself on the network To be sure that the Fastrack resets properly it must be turned off for at least 10 seconds How often the Fastrack is turned off will depend on the normal calling schedule considerations of power consumption and of how long you could afford to lose communication with the Fastrack if it did go offline When turning the power off to the modem it is advisable to avoid cutting the power when the modem is online The program examples in Appendix B check if the modem is online before turning off the power You should also avoid scheduling calls to the logger when it is due to power off If possible the AT CFUN 0 command should also be sen

25. e Fastrack will operate by default on GSM900 900 MHz or GSM1800 1800 MHz networks If you wish to use the modem on US GSM frequencies please refer to Appendix C Whenever possible a GSM900 network should be used as 1800 MHz networks which includes the Orange and T Mobile networks in the UK are designed with smaller cells because of the reduced propagation range of higher frequency radio waves Therefore GSM1800 phones have a shorter range which can cause more problems in areas of dubious signal coverage CS GSM Digital Transceiver Kits NOTE The Fastrack supplied is set up for standard GSM data transfer Please contact Campbell Scientific for more information on use for GPRS data transfer 3 1 Network Coverage NOTE 3 2 Call Charges One of the main advantages of using a cellphone network is being able to set up a communications link to a datalogger virtually anywhere without installing land or telephone lines However this only applies if a suitable GSM network covers your installation site Within the UK the coverage of GSM networks is good in most areas However coverage in remote areas can still be quite poor and is not likely to improve as it offers little commercial advantage to the network companies Unless coverage is known to be good at the proposed site we strongly recommended that you test the coverage using a standard GSM handset on the same network as the Fastrack is to be used to measure the exact signal stre

60. when designing the power supply for your Fastrack system is the possibility of only switching on the Fastrack for say one hour per day during which time a base station can be synchronised to collect data The lowest overall power consumption can be obtained by making the datalogger turn the power on only when it makes outgoing calls However this would prevent you calling the datalogger at will from a base station to check its status or to load a new program Once the total time per day that the datalogger will be turned on in its different power states is determined a daily power consumption can be estimated and the power supply designed accordingly For most typical remote applications a PS100E and a medium sized solar panel will suffice Please refer to Technical Note 12 Calculating Power Consumption and Solar Panel Size for further details To allow the Fastrack to receive calls program the datalogger to set the relevant control port high to turn the Fastrack on The Fastrack will not answer an incoming call when the power control line is low Control is normally done using the datalogger instruction If Time with the command option to set the port high after an additional check on the battery status or low at specific times The time for which the Fastrack is switched on needs to be long enough to allow an incoming call to be started data collection made and the call completed The dataloggers allow an extra refinement to this sequenc
