1 Introduction The AR-3HU / SR-3HU / S4N-3HU / KT-3HU is a self-Contained vehicle tracking device that combines GPS location with GSM/GPRS connectivity. The AR-3HU / SR-3HU / S4N-3HU / KT-3HU appears to a user or a server application as a single endpoint device. It can be queried, updated and configured either through a serial connection, or an over the air GPRS or WCDMA IP connection, or through SMS messaging.

incoming signal and the selected PRN code based on certain Carrier Doppler Frequency, Code Doppler Frequency, code phase, carrier phase, and the particular satellite the module is tracking or acquiring. GPIO Two GPIO pins, GP1 and GP2, are presented to the external environment on the main connector. They are general purpose bidirectional lines capable of providing system interrupts to generate a report or drive logic levels to external devices. These lines are 2.8V logic level and are 16V tolerant.
Timers Timers resident on the GSM baseband chip generate periodic interrupts for power down wakeup, watchdog support, report generation and other timer related functions. Report timers are supported by related AT command and cause generation of periodic reports. Watchdog MT6261D chipset provide internal software Watchdog, and a physically dedicate Watchdog circuit requirement is optional. Motion Detect (Option) A factory populates option for motion detector is provided.

101. AT+XINNET Info: Network 102. AT+XINPWR Info: Power 103. AT+XINVER Info: Versions Report The AR-3HU /SR-3HU / S4N-3HU / KT-3HU captures data and forms a report record with that data. A report is a data structure containing all of the sensory and other typically useful data on the device. Reports are generated in response to specified events, such as periodic timeout, speed threshold, geo-fence crossing, etc., or in response to a Report Now command (AT+XRN).
the logical content of the report is the same in both representations, the size for an ASCII report is twice the size of actual numbers of bytes compared to binary representation. 3.6 Reset There are a number of resets available on the device. Soft reset resets the baseband only by using an internal watchdog, while hard reset power cycles the whole device. There is also an option to reset the GPS sub-system only. 3.6.
