REV: 2.0 (GT3100-special, V1.51, GT500-SIM340.C1)
I. INTRODUCTION
PORTMAN GPS GPRS tracking system GT3100 utilize the GPS tracking function 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 8 outputs and 5 inputs to perform essential alarm functions.
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=Valid, L=Last known
(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
GT3100 must be initialized by PORTMAN PC setup program in order to make communication with the remote
server /call center. There are four 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 Geo-fence definition (up to 5 circular, 5
rectangular and 20 point Geo-fence shapes can be set in the device) (3) Report setting (Time, Distance,
Intelligent mode, Temperature, Low battery, Course change…) (4) ALARM report (to enable or disable the
event generated by the inputs, e.g. ACC, DOOR). Those data will have been saved in device’s EEPROM and
will not be lost even if the power is failure.
Note that the device ID, GPRS APN name, GPRS login name and password need to be set in initial PC setup in
order to make the connection to the server. All the reports configuration or Geo-fence setup can be changed at
anytime via over the air commands.
The automatic reporting mode can be categorized as ‘time’ report, ‘distance’ report, or ‘time & velocity’ report.
User can choose the reporting mode and related parameters via the PC setup program or the remote sever.
The event trigger report is also configurable. User can turn on or off any event-generated report from the PC
setup program or via the air command. The event-triggered report include (1) In-vehicle Door close/open (2)
In-vehicle ignition on/off (3) Temperature range in/out the preset range.
The server cannot only configure the device just like the PC setup program does, but it also can send the
command to control the device. The server can control both the device and the build in alarm.
