I. INTRODUCTION
PORTMAN GPS GPRS Tracking and Alarm System utilize the GPS and car alarm
functions in one unit. You can monitor the vehicle location and control the car alarm
remotely. In addition, the unit will send event report if any trigger occurs. It has built-in 3
outputs and 5 inputs to perform essential alarm functions. Tri-communication capability
through SMS, GPRS and SBD (Iridium’s short burst data). Tri-communication switch
automatic. Communicate with Iridium’s satellite where no GSM coverage.
1.1 Report structure
The standard report sent by the unit includes the information: (1) unit’s ID, (2) status, (3)
time, (4)GPS’s latitude and longitude, (5)speed, (6) direction, (7)temperature, (8)device’s
status, (9)event number, and (10) report configuration parameters.
(1)
Unit’s ID: each device has its own unique ID and must be registered in the server in
order to perform monitoring or controlling.
(2)
Status: ‘A’ mean the number of satellite is more than 4 or equal to 4; ‘B’ mean the
number of satellite is equal to 3, ‘L’ mean the number of satellite is less than 3.
(3)
Time: report time in Greenwich Mean time zone.
(4)
GPS’s latitude and longitude.
(5)
Speed: in km/H
(6)
Direction: in degree to the North.
(7)
Temperature: in Celsius. If the temperature is not connected, ‘NA’ will be shown in
this field.
(8)
Device’s status: there are 32 states to represent the I/O and working modes for the
both the device and the build in alarm.
(9)
Event number: all the generated reports will include a unique event number to
indicate why it has been sent.
(10) Report configuration parameters: user can remotely change the report configuration,
and the configuration parameters will be shown in this field.
1.2 Report Setup
GST8000 must be initialized by PORTMAN PC setup program in order to make
communication with the remote server /call center. There are 9 main sections that allow
users to program the device, (1) User detail (Device ID, server IP, and port, SMS number,
GPRS APN…) (2) In-built Geofence definition (up to 1 self geofence, 4 circular geofence,
5 rectangular geofence and 20 point Geofence shapes can be set in the device) (3) Report
