< 5Watts The PM-Hprovides support for specialized hardware features through extended AT commands. The features supported include the following. GPS GPIO LEDs 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. The GPIO pin, is presented to the external environment on the main connector. It is a general purpose bidirectional line capable of providing system interrupts to generate a report or drive logic levels to external devices. This line is 3.3V logic level input or output with transient voltage protection and internal pull-up resistor. GP1 is intended to use for a Door open sensor. Three 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 GPS Status On: GPS satellites acquired and Locked Flash Slow: GPS satellite search is in progress Off: No power or GPS subsystem fault On: Indicates GPRS connection is made Flash Slow: GPRS subsystem initialized but no connection Flash Fast: GPRS initialization in process Off: No power or GSM subsystem fault Orange LED is Flashing to indicate charging Green GSM/GPRS Connection Orange battery charging The PM-H provides user control allowing the LEDs to be extinguished once installation is verified. This feature reduces power and further conceals the PM-H Tracker from untrained parties wishing to defeat its operation. A UART port is provided for AT command and data interaction and optionally for connection to peripheral sensors A 500mA sink capable output pin is provided. This pin is meant to drive a relay coil indented to operate a door opening device. UART Relay Driver 2017 M-Labs Technologies5/ 14 1-Wire Bus Interface The 1-Wire bus interface can be connected to sensors that support the 1-wire serial protocol such as Temperature sensors or driver identification. 3.3V Power output is available to power peripheral sensors such a cargo sensor. The power is turned on only when the peripheral sensor is being read to save power. 3.3V Power Out Input Voltage and Battery Voltage Monitor Timers Watchdog Motion Detect The Input Voltage monitorsand battery voltage monitor are internal analog inputs scaled such that the DC value of the voltage input pin to the PM-H system and internal battery voltage 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 32V for Input Voltage and 0 to 9V for internal battery voltage 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. MT6276 chipset provide internal software Watchdog, and a physically dedicate Watchdog circuit requirement is optional. Configurable through AT commands the unit can go to a low power mode when the main power is removed until motion is detected. Upon wakening, a report can then be generated, and the GPS enabled to detect drive events. 2.2 Basic RF Performance Items TRP free space TIS free space Antenna loss Antenna Loss 2.3 Certification and Safety Items Drop Design Temperature Range Humidity:

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 PM-Hand 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 PM-H 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 2017 M-Labs Technologies8/ 14 the configuration of the device. The device can be put into several levels of low power mode whenever it runs on the internal backup battery, or if the external input voltage is low or if it is not movingdepending on how the unit is configured through AT commands. Power Mode Full Power (Track) Listen Stealth The device would return to full power whenever an event occurs that triggers a report. Those events include:
Cellular On On Off GPS On Off Off IP change Report timer GPIO change Battery threshold Heartbeat Watchdog Power-up Motion Detected Any hardware or software reset will return the device to full power mode. 3.5 Report The PM-H 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 2017 M-Labs Technologies9/ 14 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 whilethe 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. 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.
