1 Introduction
TheJG-His a self-contained trailer tracking device that combines GPS location with
WCDMA/GSM/GPRSconnectivity.It is primarily a location reporting device that responds to
requests (user, server) and events (timers, geo-fences). Data reports consist of a single record
that contains all location data and system status.

The device comes pre-configured from the factory, ready to use.TheJG-H 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, an over the air IP connection, or through SMS messaging.
TheJG-Hpresents itself over these connections as an enhanced cellular modem with attached
functional elements. These elements include:
         • GPS
         • Accelerometer
         • I/O pins and tamper alert
         • Serial UART port for management and for cargo sensor
         • Status LEDs
         • Timers
         • Watchdog lockup protection
         • Power Management
         • Power Output
         • Solar panel power supply


 Access to these elements and general purpose interfaces is done through an extended AT
 command set as defined herein.Configuration parameters are stored to flash memory and
 are automatically used on the next power up event. For more details, please reference the

The JG-Hprovides support for specialized hardware features through extended AT commands.
The features supported include the following.

GPS
GPS location functionality is provided by the device GPS receiver. Warm start from sleep is
supported.

GPIO
One general purpose GPIO and three additional multiplexed IO’s are presented to the external
environment on the main connector. They are 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. The multiplexed IO’s are typically configured as Ignition, Relay and
Tamper.

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 well as the power input; 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: GPS is turned off
 Green          Cellular       On: Indicates cellulardata connection is available
                Connection     Flash Slow: cellular subsystem initialized but no connection
                               Flash Fast: cellular initialization in process
                               Off: Cellular sub-system is off
 Orange         Battery        On: Indicates external power and battery is fully charged
                charging       Flash: Indicates external power and battery is charging
                               Off: Indicates running from battery. Blinks shortly every
                               30sec.

The JG-H provides user control allowing the LEDs to be extinguished once installation is
verified. This feature reduces power and further conceals the JG-H Tracker from untrained
parties wishing to defeat its operation.

Accelerometer
The accelerometer is used for motion start detection to wake the unit up from a sleep mode
and driving behavior monitoring.

UART
A UART port is provided for AT command and data interaction. The UART can also serve to
attach other accessories, such as cargo sensor.

1-Wire
A 1-Wire interface is supported to attach external sensors, such as temperature sensor, etc.

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.

Ignition Monitor
One of the GPIO’s can be wired to vehicle ignition to monitor and trigger event upon ignition
start and stop.

Power Out
The JG-H provides a power out option at 3.3V and up to 300mA to enable powering up
external devices. The power out is turned off by default and is controlled by software.

Tamper
Tamper detection pin is available on the external connector. The Tamper pin can trigger an
alert when disconnected from ground.

Solar Panel
The JG-H includes an integrated solar panel that constantly charges the battery when exposed
to light.

Power Monitor
The internal power monitor circuitry allows to measure the voltage on all possible power
sources: Main, Auxiliary, Battery, Solar.

Timers
Timers resident on the baseband chip generate periodic interrupts for power down, wakeup,
report generation and other timer related functions.

3.2     Remote Update
The JG-Hsupports OTA field upgrades of the JG-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 JG-Hand that file replaces the previous application
image.

3.3     Power Modes
The JG-H device supports several power modes that are set by AT commands. 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 a sleep mode whenever it runs on an internal battery, if the external
battery is low or if the device is not moving. In low power mode the GPS is not running and
the LED’s are off. The device would return to full power whenever an event occurs that
triggers a report. Those events include:
          • GPIO change
          • Battery threshold
          • Heartbeat
          • Power-up
          • Accelerometer
          • Tamper
Any hardware or software reset will return the device to full power mode.

3.4    AT Command
JG-Hcommands are AT extensions specific to JG-H devices. They are closely based on
commands that are as similar as possible to other industry common devices. Native AT
commands supported by the baseband modem are also available via the serial interface.

Command Summary
The following commands are specific to the JG-H. 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 ID’s. Those default event ID’s 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:


         1. AT+XBTLE                Battery Low Event

Report
The JG-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, the device 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 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 JG-H 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 are encoded as binary hex.

3.5    Reset
There are a number of resets available on the device. Soft reset only restarts the baseband on
the device. Hard reset is caused by resetting the whole baseband module via a reset pin. There
is also an option to reset the cellular and GPS sub-systemsindividially.

3.5.1 Context Preservation
When a self-initiated reset is performed due to 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 or preventive measure 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.

3.6    Startup Banner
After a reset a startup banner is printed through the UART only.
