< 5Watts The AR-2GM provides support for specialized hardware features through extended AT commands. The features supported include the following. GPS The major functionality of the GPS module is to compute the correlation results between the 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 2016 Connected Holdings LLC 4 / 19 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. These pins default to input. GP1 is pulled down representing 0 when disconnected; GP2 is pulled up representing logical 1 when disconnected. They should be asserted to a known value if used. GP1 is intended to use for Ignition Sensing. LEDs Two LED status indicators are provided to verify correct installation and operation. The status LEDs are color coded and directly convey the status of the cellular and GPS subsystems as described in the table below. Their valid operation also indicates operational status and power. LED Red Function Status GPS On: GPS satellites acquired and Locked Flash Slow: GPS satellite search is in progress Off: No power or GPS subsystem fault Green GSM/GPRS On: Indicates GPRS connection is made Connection Flash Slow: GPRS subsystem initialized but no connection Flash Fast: GPRS initialization in process Off: No power or GSM subsystem fault The AR-2GM provides user control allowing the LEDs to be extinguished once installation is verified. This feature reduces power and further conceals the AR-2GM Tracker from untrained parties wishing to defeat its operation. UART A UART port is provided for AT command and data interaction and optionally for application specific control. Relay Driver A 500mA sink capable output pin is provided. This pin is meant to drive a relay coil indented to interrupt the starter solenoid relay for the ignition circuit to a car. Battery Monitor The battery monitor is internal analog input scaled such that the DC value of the power input pin to the AR-2GM system is measured. This value is scaled to span the most significant 8 bits of the A/D and consequently covers a scale from 0 to 25.5 Volts. 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 2016 Connected Holdings LLC 5 / 19 circuit requirement is optional. Motion Detect (Option) A factory populates option for motion detector is provided. If populated at the time the AR-2GM is manufactured, this option will work with firmware power down options to keep the AR-2GM in a very low power down state until motion is detected. Upon wakening, a report can then be generated. 2.2 Basic RF Performance Items TRP free space TIS free space Antenna loss Antenna Loss Requirements Remark

An over the air TFTP (Trivial File Transfer Protocol) connection is made over a UDP/IP connection. A replacement file is then transferred from a server to the AR-2GM and that file replaces the previous application image. 3.3 Auto Execute The Auto Execute Utility copies the contents of file system.exf into system executable RAM and executes it from there. This file is the factory default application. Another file named custom.exf can be loaded into the file system. Auto Execute will look first for a file named update.exf and load and execute that in place of custom.exf if it exists. If update.exf executes successfully, the previous copy of custom.exf is deleted from the file system and update.exf is renamed to custom.exf. 3.4 Power Modes The AR-2GM device supports several power modes that are set by the power mode command. In full power mode the GPS is active and the cellular subsystem will maintain a persistent cellular connection whenever service is available. IP connection is maintained according to the configuration of the device. The device can be put in low power mode whenever it runs on a backup battery or if the external battery is low or if it is not moving. In low power mode the GPS is not running and 2016 Connected Holdings LLC 9 / 19 the LEDs are off. The device would return to full power whenever an event occurs that triggers a report. Those events include:
Report timer GPIO change IP change Battery threshold Heartbeat Watchdog Power-up Any hardware or software reset will return the device to full power mode. 3.5 AT Command AR-2GM commands are AT extensions specific to AR-2GM devices. They are closely based on commands that are as similar as possible to other industry common devices and are essentially subsets of standard AR-2GM commands. Common commands used with GPRS modems supporting IP connectivity are not included within the AR-2GM command set extensions. These commands are left in their native structure, as defined by the respective baseband GSM chip supplier which product already in use. Command Summary The following commands are specific to the AR-2GM. They are organized by categories. Event Setting Commands The following set of commands enables/disables reporting of the various events and state transitions that take place in the system. The event setting commands typically include trigger(s) that indicate what event or state transition would cause an event report to be sent. Often state transitions also qualified with debounce time to prevent various flickers and intermittent state transitions. Examples are: (1) state change of an input pin; (2) crossing a geo-fence line for a brief period of time and then crossing it back. As a general rule every event and state transition has its own unique event ID that is reflected in the report triggered by the said event. Refer to Table 2 Events for the complete list of event IDs. Those default event IDs can be changed by the user to accommodate specific server implementations, by explicitly specifying what they are in the respective commands. As an example, all trip related events can be mapped to the same event ID, so there is no need to parse the specific event trigger. Following is a list of event setting commands:

AT+XINPWR Info: Power 2016 Connected Holdings LLC 13 / 19 103. AT+XINVER Info: Versions Report The AR-2GM 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). Report Queuing If a report trigger occurs while UDP connection is unavailable, it will be queued until connection becomes available and transmitted at such time. The only way report(s) can be lost is if too many reports are queued and the report-queue is overflowing. In such case the earliest report(s) will be discarded. The size of the queue can be configured via the Report Queue
(AT+XRPQ) command. Acked Mode UDP is not a 100% reliable connection and occasional reports or command/responses may be lost. Since all commands have responses, the server can repeat any command to which there is no response. In order to assure reliable reception of reports, Arsenal devices can be configured either in Normal or Acked mode to send the reports. In the Normal mode the reports are simply sent as is with no acknowledgment from the server. In the Acked mode every report sent is expected to be acknowledged by the server by sending back an ACK message back. If acknowledgement is not received within the specified timeout, the report is re-sent. If the report is not acknowledged after the specified number of attempts, it is queued. If acknowledgement is received after the report is queued (i.e. past timeout of the last attempt), it is ignored. Report is not considered complete until its acknowledgement is received. Thus, if report X is sent and report X+1 is triggered while waiting for acknowledgement of X, report X+1 will be queued until such acknowledgement is received and only then sent. The Arrow will attempt to re-send queued report(s) every time a new report is triggered. If there is more than one report queued, the reports will attempt to be sent in the order of triggering and only once the report is acknowledged, the next report is attempted. This assures that reports are sent and received in order. Acked mode assures that all reports are received, but adds overhead in time and data. Report that is not acknowledged is sent again and eventually will be queued and sent again. The number and frequency of re-tries is configurable via the Report Acknowledgement command
(AT+XRPA). Event Report Format Reports can be generated in either an ASCII representation of hex or as actual binary encoded hex. The reporting format is selected via Report Format (AT+XRPF) command. Note that 2016 Connected Holdings LLC 14 / 19 while 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. 3.6.1 Context Preservation When a reset is caused by the Network Watchdog or by the Reset command (modes 0,1), the context of the system is being preserved and is restored after the reset. The context includes all the periodic timers, the report queue, the odometer, etc. This allows to reset the unit as a troubleshooting measure either periodically or due to Network Watchdog without losing reports that are already in the queue or are pending on running timers. Note that the reset process may cause 1-2min of inaccuracy in the timers and should not be considered as very precise. 3.7 Startup Banner After a reset a startup banner is printed through the UART only. The format and content of the banner shown below:
