1 Introduction
ThePM-His a self-Contained vehicle tracking device that combines GPS location with
GSM/GPRS/WCDMA connectivity.
ThePM-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, or an over the air GPRS or
WCDMA IP connection, or through SMS messaging. ThePM-Hpresents itself over these
connections as an enhanced cellular modem with attached functional elements. These
elements include:
GPS location engine
1 General Purpose Bidirectional I/O (GPIO) pin
1 Relay drive pin output
1 1-Wire Bus Interface
3.3V Power out for Peripheral Sensors
Serial UART port
Input voltagesand Battery Voltage monitor
Timers
Watchdog lockup protection
Motion detection
Access to these elements and general-purpose interfaces is done through an extended AT
command set as defined herein.
Application scene:
This product will be designed based on the 2G or WCDMAwirelessdata/MT6276
Baseband chipset, which includes GPS functionality, ARM CPU and GPRS protocol.
This baseband internal connection 8M serial flash, GSM 900M/1800M/GPS RF
Transceiver, and RF Front end circuit.

Power Consumption
The PM-Hprovides support for specialized hardware features through extended AT commands.
The features supported include the following.
< 5Watts
GPS
The major functionality of the GPS module is to compute the co rrelation 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
Connection
charging
The PM-H provides user control allowing the LEDs to be extinguished once installation is
verified. This feature reduces power and fu rther 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.
