See chapter 5.6 for the SMS command and response format.● Optimized Auto ReportConfigure the Auto Report function to enable optimized GPS position update rates for ‘moving’ and‘stationary’ operation, thereby minimizing wireless data network usage. For more information,please refer to chapter 5.1.2 for settings.● Vibration DetectionThe CT-24(TA)F can be installed with a vibration sensor accessory. When the GPS tracker detectssudden vibration occurring, the tracker can immediately send a GPS position update. For moreinformation, please refer to chapter 4.6 and 5.3 for settings.● Reed Switch AlarmThe CT-24(TA)F can be installed with a magnetic reed switch accessory. When the magnetic reedswitch is opened, the CT-24(TA)F will immediately send a GPS position update. For moreinformation, please refer to chapter 4.7 and 5.2 for settings.● SOS AlarmAn SOS alarm is included in the CT-24. When the SOS button is pressed, the tracker willcontinuously send GPS position updates at a pre-determined time interval. For the relatedinformation, please refer to chapter 4.9 and 5.10.● Data Logging MemoryThe CT-24(TA)F includes some flash memory which allows it to ‘Store and Forward’ up to 1000GPS location reports in cache, when out of the GSM coverage area, e.g. in rural areas or at sea.When the CT-24(TA)F returns to the GSM wireless coverage area, then all the stored locations areautomatically transmitted to the server. Additionally the CT-24(TA)F can be programmed to storemultiple GPS location reports in cache until the number stored reaches some desired amount (e.g.5 or 10 GPS reports, etc.). Then the GPS reports are all transmitted together. This can reduce theGPRS channel setup time and also the wireless carrier usage charges if the wireless carriercharges the data usage for each GPRS channel session.3.4 ApplicationsFleet Management , Vehicle Security and Recovery, Asset trackingCT-24(TA)F User Manual 10 Copyright © SANAV/ElectronGPS Corp - all rights reserved

5 SMS Setup5.1 Optimized (Dual Interval) Auto ReportThe ‘Optimized Auto Report’ function enables the user to increase the auto report interval when theCT-24(TA)F is stationary, thus reducing the wireless data usage and yet still maintaining a shortauto-report interval when the CT-24(TA)F is moving. This is very important for reducing costs incommercial fleet management applications, where the CT-24(TA)F is permanently installed in a vehicleand the company vehicles have long periods when they are stationary, (e.g. vehicles parked for hours ata customer location or parked overnight and at weekends at the company storage depot). A 66%reduction in wireless data usage is typical, but the exact savings are dependant on the CT-24(TA)F set upand device mobility patterns.Setup format : # Username,Password,Function Code,Moving Report Interval (seconds),TotalReports,Moving Distance Threshold(meters),Stationary Report Multiple*Example1:#username,0000,6,240,99,100,15*In this example, the ‘Moving Report Interval’ is 240 secs (i.e. 4 mins), the total reports is 99, the ‘MovingDistance Threshold’ is 100 meters and the Stationary Report Multiple = 15. So the ‘Stationary UpdateInterval’ is ‘Moving Report Interval’ x ‘Stationary Report Multiple’ = 240secs (i.e. 4 mins) x 15 = 60mins.Table 5.1.1 below describes the meaning of each parameter in the message above.Setup format : # Username,Password,Function Code,Moving Report Interval (seconds),TotalReport,Moving Distance Threshold(meters),Stationary Report Multiple*Example1:#username,0000,6,240,99,100,15*CT-24(TA)F User Manual 21 Copyright © SANAV/ElectronGPS Corp - all rights reserved

5.1.2 Auto Report DefinitionThere are three main parameters to this function, ‘Interval’, ‘Stationary Multiple’ and ‘GeofencingDistance’:Interval - the period at which the current GPS position is always compared to the last transmitted (notlast measured) GPS position. It is typical to set the (‘moving’) Interval at 1, 2 or 5, etc. minutes, asrequired. So, if the CT-24(TA)F is installed in a vehicle which is moving at 60 miles per hour (i.e. 1 mile perminute) then it will update every 1, 2 or 5 miles, depending on the Interval setting.Geofencing Distance (or ‘Moving Distance Threshold’)- the distance relative to the last transmitted(not last measured) position which defines the boundary of the ‘stationary’ geofencing region. Thus, the‘stationary’ geofencing region is a virtual circular area with its center located at the last transmitted GPSposition, with the Geofencing Distance as its radius (see diagram below). For normal operation, it istypical to set the Geofencing Distance at 50-100 meters to allow for typical GPS position jitter error whenthe CT-24(TA)F is stationary. When testing, set the Geofencing Distance at 1 meter if the CT-24(TA)F isstationary and you want to force the CT-24(TA)F to transmit at the ‘moving’ Interval period (e.g. 1, 2, or5 mins, etc.). Similarly, if the CT-24(TA)F is stationary and you want it to auto-report at the 'stationary'update rate, then set the Geofencing Distance to a large value, e.g. 1000 meters.Stationary Multiple - the factor between the ‘stationary’ and ‘moving’ update rates. Thus, the stationaryupdate period = Interval x Multiple. As an example, if the Interval is set at 2 mins, the Multiple at 30, thenthe current GPS position is checked every 2 mins and if the CT-24(TA)F is stationary, it will update every60 mins (i.e. 2 min x 30 = 60 mins).After being configured, the optimized auto-report function is permanently enabled and the CT-24(TA)Fwill continue to auto-report its position until the CT-24(TA)F is switched off.The reduction in GPRS wireless data usage is dependent on the amount of time that the CT-24(TA)F isstationary and the Multiple. As an example, if the CT-24(TA)F Interval was set at 2 mins with a Multiple of1, then the monthly number of auto-report position updates is 21,600 (i.e. 21,600 = 30 measurementsper hour x 24 hours per day x 30 days per month). This is equivalent to about 5MBytes of monthly datausage, since each GPS position update requires about 240 bytes (including GPRS data channel set up andtear down overhead). Now if the same CT-24(TA)F was set with an Interval of 2 mins and with a Multipleof 30 and the CT-24(TA)F was installed in a vehicle that was moving for 8 hours per day, then the totalnumber of GPS auto report updates would be 7680 (i.e. 7,680 = 30 measurements per hour x 8 hours perday x 30 days per month, plus 1 measurement per hour x 16 hrs per day x 30 days per month) equivalentto approximately 1.8MBytes. Thus in this case, the reduction in data usage would be approximately 64%.CT-24(TA)F User Manual 23 Copyright © SANAV/ElectronGPS Corp - all rights reserved

EXAMPLE OF USAGE1. CT-24(TA)F StationaryCT-24200metersCommand: #username,0000,6,2,30,200*If the auto-report command is set as above, the CT-24(TA)F will define a virtual circle (geofencingregion) of radius 200m (geofencing distance) from the last GPS position update transmission (notthe last GPS measurement). The CT-24(TA)F checks its position every 2 minutes, as defined by theInterval.If the CT-24(TA)F is stationary and doesn’t move beyond the geofencing region at the nextmeasurement Interval, it won’t transmit its current position and it won’t update the center of theof the geofencing region. If the CT-24(TA)F has still not moved outside the region by the timedefined by Interval x Multiple (i.e. 2 x 30 = 60 mins) since the last GPS transmission, then transmitthe current GPS position and update the center of the geofencing region and the last transmissiontime. Repeat the process at the next measurement Interval.2. CT-24(TA)F Moving200 meters200 metersIf the CT-24(TA)F moves beyond the geofencing region at the next measurement interval, theCT-24(TA)F transmits its current GPS position and then uses that position as the center of the newcircular geofencing region defined by the geofencing distance.

This auto-reset feature is very useful when roaming across wireless carriers in Europe, when theCT-24(TA)F finds it difficult to drop the current wireless carrier country code settings. Then the CT-24(TA)Fcannot quickly re-synchronize to the new wireless network, even under good GSM signal.The auto-reset function is programmable by SMS message and Programming Utility and the SMScommand format is as the follows:Setup format: #[username],[password],[rst],[minutes]*Example :#username,0000,rst,1*#username,0000,rst,0* default ( 0 = deactivated )The table 5.14.1 describes the meaning of each segment in the message above.Text Keyed In SMSDescription# Start sign.

After two minutes of no BCCHbeing received, the CT-24(TA)F automatically resets its GSM module.5.15 Operate Log FunctionThe command mode 21 defines the data logging mode of the CT-24(TA)F. There are two log modes thatcan be defined: 1) ‘Backup’ mode and 2) ‘Interval Log’ mode.‘Backup’ mode automatically stores up to 1000 GPS reports in cache memory when the CT-24(TA) is outof GSM signal coverage. As soon as the CT-24(TA) returns to an area with GSM coverage, the cached GPSreports are forwarded to the previously defined destination, e.g. a web-server. This mode is useful whenthe CT-24(TA) is operating in rural areas or in coastal waters.‘Interval Log’ mode stores all GPS reports in cache until the specified interval number of reports is reachedand then transmits all the reports in one data burst. This can reduce the overall number of datatransactions and minimize the wireless data usage ‘rounding’ fees.To set up the data logging mode, use the following SMS command format :Setup format:#username ,Password ,21 ,0,1, or 2 *Example:#username,0000,21,0* ( 0 = Off, 1 = Backup mode, 2 = Interval Log mode)The table 5.15.1 describes the meaning of each segment in the message above.Text Keyed In SMS Description# Start sign.Default ID of CT-24(TA)F.

When the CT-24(TA)F is in GPRS/SMS mode, it will upload the data to the assigned URL first.However, if GPRS service is not available, the CT-24(TA)F will send the SMS to the first predefined phonenumber instead.In the case of GPRS-only mode, CT-24(TA)F will only send the data by GPRS, no matter if there is GPRSservice or not.Basically, there are five different situations that trigger the CT-24(TA)F to respond with its position, i.e.Optimized Auto Report, Polling Report, Vibration Sensor alarm, Reed Switch alarm, SOS, Low Power alert.These situations are shown in the following pages.Table 6.0 below describes the events which trigger the various response message suffixes.EventAUTOBAUTOOPEN &CLOSEVibrationPOLLSOSLPDescriptionsWhen a valid Auto Report update is sent from the CT-24, the position update messageformat will include an “AUTO” at the end of each GPRMC sentence.When a valid Auto Report update is sent from the CT-24 cache memory (i.e. when in datalogging mode), the position update message format will include an “BAUTO” at the endof each GPRMC sentence.When the magnetic reed switch accessory is opened, the tracker will immediately send areport including an “OPEN” or “CLOSE” at the end of each GPRMC sentence.When the vibration sensor accessory experiences a sudden vibration, the CT-24(TA)F willimmediately send a report including a “Vibration” at the end of each GPRMC sentence.When using the SMS to poll the report, the event will be “POLL”.When the SOS function is triggered, the report will be sent. The report will send a reportincluding a “SOS” at the end of each GPRMC sentence.When the battery level of the CT-24(TA)F is low, a low power alert message will beimmediately sent. Note that the GSM module of the CT-24(TA)F gets reset automaticallyevery 2mins when in a low power condition. This ensures that the GSM module does notget into a ‘lock up’ condition when the external DC power is restored to the CT-24(TA)Fand the normal battery level condition is restored.Table 6.0CT-24(TA)F User Manual 46 Copyright © SANAV/ElectronGPS Corp - all rights reserved
