The PM-Hprovides 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
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.
LED’s
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 Function Status
Red 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
Connection
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
battery
charging
Orange LED is Flashing to indicate 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.
UART
A UART port is provided for AT command and data interaction and optionally for connection
to peripheral sensors
Relay Driver
A 500mA sink capable output pin is provided. This pin is meant to drive a relay coil indented
to operate a door opening device.
© 2017 M-Labs Technologies6/ 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 Out
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.
Input Voltage and Battery Voltage Monitor
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
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
MT6276 chipset provide internal software Watchdog, and a physically dedicate Watchdog
circuit requirement is optional.
Motion Detect
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.

3.2 Remote Update
The PM-Hsupports OTA field upgrades of the PM-Hresident application. 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 Technologies9/ 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.

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
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.
Ack’ed 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 Ack’ed mode to send the reports. In the Normal mode the
reports are simply sent “as is” with no acknowledgment from the server. In the Ack’ed 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 Technologies10/ 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.
Ack’ed 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. The format and content of
the banner shown below:
