Introduction
The JG-LSis a self-contained LTE CAT1/3G wireless tracking device targeting trailers.
The device combines GPS location with LTE /WCDMA connectivity. I t is primarily a
location reporting device that responds to requests (user, server) and events
generated by timers, geofences, sensors, etc. Data reports consist of a single
record that contains all location data and system status.
The device comes pre-configured and ready to use from the factory. The JG-LS
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
LTE or WCDMA IP connection, or through SMS messaging. The JG-L Spresents itself
over these connections as an enhanced cellular modem with attached functional
elements. These elements include:
GPS location engine
2 General Purpose Bidirectional I/O (GPIO) pins
1 Relay Output
1 Tamper
1 1-Wire Bus Interface
3.3V Power out for Peripheral Sensors
Serial UART port
Input voltages and Battery Voltage monitor
Timers
Watchdog lockup protection
Motion detection
Power Management
Access to these elements and general-purpose interfaces is done through an
extended AT command set. Configuration parameters are stored to flash memory
and are automatically used on the next power up event. For more details, please
reference the AT Command document.
This device is designed based on the Quectel EC21-A (4G LTE CA T 1/3G fallback,)
baseband module. Antennas for cellular and GPS are internal to the device.

The JG-LS provides support for specialized hardware features through extended AT
commands. The features supported include the following.
GPIO1 and GPIO2
1-Wire Bus Interface
GPS
GPS location functionality is provided by the device GPS receiver. NMEA GPS
records can be extracted in real time from the unit via the UART connection using
special debug commands that are outside the scope of this document.
GPIO
Two general purpose GPIO and two 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
3.3V 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.

30sec.
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 operate a door opening device.
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-L provides a power out option at 3.3V and up to 1A 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.

Remote Update
The JG-LSsupports OTA field upgrades of t he J G-LSr esident 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-LSand that file replaces
the previous application image.
Power Modes
The JG-LS 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 t he 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.
Report
The JG-LS 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.
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 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
© 2018 Spireon, Inc.8 / 12
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-LS will attempt to re-send queued report(s) every time a new report is
triggered. If there is more than one report queued, the repo rts wil l attempt to be sen t 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.
Event Report Format
Reports are encoded as binary hex.
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-systemsonly.
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.
Startup Banner
After a reset a startup banner is printed through the UART only.
