Introduction
The JG-LSis a self-contained LTE CAT1/3G wireless tracking device targeting trailers.
The device combines GPS location with LTE /WCDMA connectivity. It 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 CAT 1/3G fallback,)
baseband module. Antennas for cellular and GPS are internal to the device.
