  • Page 3: Product Overview

    Product Overview The AT200 is low-cost vehicle tracking device, housed in a sturdy plastic enclosure. Both GPS and GSM antennas are internal. The AT200 incorporates the very latest technology, including the latest Cortex M3 ARM processor, SIMCom SIM800H Quad Band GSM/GPRS modem with Bluetooth and SiRFstar IV GPS with high sensitivity and anti-jamming features.

  • Page 5: Hardware Description

    Overall Dimensions 60 x 58 x 18 mm Back-up battery Each AT200 is supplied with a 900mAh back-up battery, which is fixed to the PCB and connected as shown below: Basic electrical connections A permanent connection to +12V/+24V vehicle power should be provided to the AT200 using the RED and BLACK wires, via a 1A fuse.
  • Page 6 The SIM should be inserted in the slot at the rear of the device (with plastic enclosure fitted). The image on the device gives guidance for correct orientation. Note that the AT200 powers up when the SIM is fitted. For shipping with SIM fitted, we suggest extracting the SIM a few millimetres to power off the device.
  • Page 7 Digital Output The AT200 is capable of switching an external load of up to 30V, 0.5A using a MOSFET Low Side Switch, which must be used to switch the GND side of the load. The use of a 1A in-line fuse with these switches is essential to prevent any damage through fault scenarios.

  • Page 9 The AT200 has a versatile set of features to facilitate detailed customisation. Programming with an ASCII Terminal Custom configuration of the AT200 is best achieved via a serial interface to a PC. It is possible to use any ASCII terminal program (e.g. HyperTerminal, Teraterm, ProComm, Com7 etc.) to enter commands.
  • Page 10 Multiple Command Format In SMS mode it is often convenient to send several commands together in one SMS or packet. It is possible to append multiple commands together as described below. Example 1 $DIST,50<CRLF> $GPSQ,100<CRLF> Example 2 (recommended format for TCP/UDP mode) $DIST,500$APPW,orangeinternet$FRED,1 Multiple Command Response Format Multiple commands received at the same time via any mode will result in one response for each...

  • Page 11: Application Parameters

    RESERVED TCP Acknowledgment Timeout (TCPT) This parameter specifies the maximum number of seconds that the AT200 device will wait for the host to send the ACK code in response to sending a report. The default value is 30 seconds. A value of zero will disable the acknowledgment feature.
  • Page 12 The AT200 supports various reporting protocols (data packet formats). Protocols used by other devices are implemented for compatibility with existing systems. To take advantage of the full AT200 feature set, the specific AT200 protocol “K” is recommended. Documentation for each of these protocols is available on request from Astra Telematics, please email support@gps-telematics.co.uk...
  • Page 13 1 when setting the <ignition_source>. When IGMN=3 the AT200 will detect that the vehicle engine is running from the increase in external voltage (typically, the vehicle battery voltage increases by 2 Volts whilst the engine is running.
  • Page 14 IGNM mode 3. STOP Report Delay (STPD) When IGNM is set to zero (see above), the AT200 will determine journey START and STOP events based on movement data from GPS, accelerometer and tremble sensor. A STOP event will occur after the vehicle has remained stationary for a pre-determined time.

  • Page 15: Bluetooth Pairing

    Host server authentication / authorisation for driver IDs can be enabled using the DRIC command (see above). When enabled, the AT200 will store a list of up to 10 approved Driver IDs and up to 10 declined Driver IDs. The source of the Driver ID is set using the DRIC command.
  • Page 16 $DRID,VERIFY,<hours> Host request to set the device whitelist verification period (0- 65535). 0 disables the request For example: $DRID,AT200,CHECK,351777042187300,01,0000125408C9 For Bluetooth Driver IDs the CHECK command uses family code 00 and has an extra field <bluetooth-device-name> at the end.

    Pass through data mode enable. Default is 0. Set this parameter to 1 to enable Pass Through Data Mode. Note that when Pass Through Data Mode is enabled, debug and NMEA output are suppressed from the AT200 serial port (DBUG and NMEA set to zero). Please refer to the appropriate Application Note for further details.
  • Page 18 This parameter can be used to control SMS costs by setting a monthly limit on the number of SMS which may be sent from the AT200. A value of zero will disable the Monthly SMS Limit feature. Default is 50.
  • Page 19 For CLID=3 when GPS is invalid any event that generates a report or a reply to $POLL or $POSN will cause the location to be requested from the GSM network, but only if the last request was more than <request_period> minutes ago. The status in the report will indicate that the location is network based in addition to invalid GPS.
  • Page 20 Tow Alert Parameters (TOWP) A tow alert (i.e. report with REASON bit set indicating tow alert event) is generated whenever movement is detected whilst the vehicle ignition is off. This scenario is detected using a number of different sources, including GPS speed, GPS location, accelerometer and mechanical tremble/motion sensor.
  • Page 21 Utility and Engineering Commands Delete All Geofences (GEOD) Individual geofences can be deleted by setting <type> to zero. The GEOD command provides a convenient way of deleting all geofences. Configure Digital Outputs (CDIG) Where the output is controlled in response to an event the digital output can be configured using this command.
  • Page 22 Accelerometer Wake-up Interrupt Configuration (MEMS) Allows configuration of the criteria for wake from sleep based on accelerometer motion detection. $MEMS,<threshold>,<time-limit> Immobilise (IMOB) Set digital output for purposes of vehicle immobilisation, giving the option of making the activation conditional on vehicle ignition status and speed to ensure safe immobilisation. When this command is used, the output will remain in the ON (activated) state until $IMOB,0 is received to clear the immobilise condition.
  • Page 23 Resets all parameters to factory defaults (or client defaults) as built into the device firmware. Position on Demand (POLL) The AT200 will send an update report to the host server in response to a variety of user- configurable events. The POLL command can be used to request an update when there is no event to report.
  • Page 24 (see DBUG to enable/disable other serial output). Default is 1. Serial Port Baud Rate (BAUD) Configure the baud rate of the AT200 RS232 serial port. Default is 115200. Display Settings (SHOW) Display settings in readable ASCII format (not recommended for TCP/SMS, see PARA) Send SMS (SSMS) Send an SMS text message.
