1 Introduction
The PM -L is a self-contained LTE CAT1/3G wireless tracking device targeting trailers. The
device combines GPS location with LTE/GSM/GPRS/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 PM-L 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 PM-L presents 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 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.
