OBD-II Connector
OBD-II was introduced in the United States on January 1, 1996, all cars and light trucks built and sold
were required to be OBD II equipped (models built in late 1995 then on were OBD-II compliant).
There are two factors to identify if your vehicle is definitely OBD II equipped:
1) There will be an OBD II connector as shown in Figure 1A below, and
2) There will be a sticker note or nameplate under the hood indicating: "OBD II compliant".

Location of OBD-II connector
Look for your OBD-II under the dash and behind ashtrays. The OBD-II connector must be located
within three feet (0.914 meter) of the driver, and must not require any tools to be revealed.
4.2.5.
Communications Protocol
The protocol used in vehicle varies for different manufacturers – the GM cars and light trucks use SAE
J1850 VPW (Variable Pulse Width Modulation), while Fords use SAE J1850 PWM (Pulse Width
Modulation). Chrysler products, all European and most Asian imports use ISO 9141 circuitry.
There are some variations among captive imports such as the Cadillac Catera, a German Opel
derivative, which uses the European ISO 9141 protocol.
On 1996 and later vehicles, you can tell which protocol is used by examining the OBD II connector:

contents are the sole copyright of the respective owner and organization.
If your vehicle has this style connector, but doesn't have these pins populated, you probably have a
pre-OBD-II vehicle. Adding to some other confusion, even having the connector with the contacts
shown above is not a guarantee of OBD II compliance. This style connector has been seen on some
pre-1996 vehicles which were not OBD II compliant.

5. Application
5.1
Application Scope
The AVL75 is highly integrated hardware device that provides communication and automation, which
is built on the embedded WinCE O/S software, enabling the users to make the necessary modification,
while achieving different industrial application.
AVL75 is equipped with the following external connectors – the GSM antenna connector, the GPS
antenna connector, WIFI antenna connector, the RS232C connector, the power connector, and an
internal SIM card holder connector.
Attaching the GSM/GPRS antennas, it would provide communication for vehicle security and
monitoring. Whilst the RS232C connector is used for the interaction with personal computer (or
with notebook) – for the configuration to the business enterprise in providing a stand-alone tracking
operation mode. In some cases, GPS data collecting and the Map representation for user
application can be done without GSM network.
5.2
Vehicle Security & Monitoring
The security monitoring plays an important role for AVL. Most AVL suppliers integrate security
connector with external sensors, like shock-sensor and microwave-sensor. Suppliers provide
interfaces with a central lock of a vehicle, with a parking vehicle’s lights, with the system of ignition’s
blockage and with the siren.
Such security interface may include control activities like:
A. Inputs
Sensor input (different ranges)
Opened/closed doors
Ignition wire
B. Outputs
External 433 MHZ RF Antenna
Ignition blockage
Siren output
Central Lock (close and open the doors),
Automotive Parking Lights
External LED
12V power wires.
AVL75 can work independently without security control and other add-on components/parts.
needs no changing of the software, just remove the additional modules from the AVL unit.

6. Hardware Overview
The AVL Unit is a device, designed for Vehicle’s Tracking and Guarding that transfers data from this
device to the designated or assigned WEB server and transfer back using GPRS terminal for SMS
(Short Message Service) or TCP/IP data transferring. Also the SMS messaging is organized in the
stand-alone operation mode, i.e. data transferring toward and back to the user’s mobile phone.
The AVL75 unit is organized on the principle of modular expandability.
A principal basic base module (Vortex86 CPU board) of the AVL75 represents a computer system,

9. Software Support
DMP provides the AVL75 hardware solution to the software developers who will develop the A/P and
SQL database for AVL system.
9.1 Summarizing the AVL software
AVL software is divided into 3 categories, namely:
1. Database server and data transmission server
2. Backstage control software
3. AVL client point software.
9.2. Database and Data transmission server
When the AVL client is hooked up online, the data transmission server would first access to the
database to capture the information, then these data is delivered to the client end, and the AVL client
will gather all the needed information and write back to the database in return.
9.3. Backstage control management program
We suggest to use MDI method to convert and write a program (this single program can open many
map windows/GUI), at the same time, read & retrieve database.
9.3.1.
9.3.2
9.3.3.
This is a new addition of the current windows browsing situation (MAP interface), can either
select single task windows fix locked, or free view mode.
New history information broadcast on the windows site.
All client points history and status summary.
With regards to the client end settings, the backstage program will manage the control. After the
user managed the program settings, he can send the information to the internet for transmission or
transport (remit) to a USB flash memory, then update the client end settings again.
Setting parameters detailed contents are as follows:
1. GPI Event monitoring setting, can be set as GPI event touch off for power-on time and request for
report back of the content of the data. We can also set GPO touch off time and length.
2. Wake on Ring setting, can be set as Wake on ring event touch off for power-on time and request
for report back of the content of the data. We can also set GPO touch off time and length.
3. Wake on timer setting, can be set as Wake on timer event touch off for power-on time and request
for report back of the content of the data. We can also set GPO touch off time and length.
4. OBD-II monitoring setting, can be set as retrieving of OBD-II condition establishment touch off
for power-on time and request for report back of the content of the data. We can also set GPO
touch off time and length.
5. Coordinates monitoring setting, we can set a single client end to move the coordinates within the
coordinates scope, if it is over the range, it will report back and set GPO touch off time and length.
6. Automobile single-stop monitoring is over the limit of monitoring manageable time, can be set to
report back of information, and can also set GPO touch off time and length.
7. Can set partial data transfer to another specific AVL client, or pre-call action.
As far as backstage software, it can be set as password necessary for use, then multiple password
with different authority level (for example, client end is set to monitor the completeness of data.
9.4.
AVL Client software part
In accordance to setting and the selection with added decision, and these parameters must report
back to the data transmission server.

9.5.
Principles of operation
After the installation with the necessary set-up, the AVL75 will start to work immediately. As soon
as the internal GPS receiver catches the GPS signals, the device starts to form the packets with the
geographical coordinates.
If your local place is covered by GSM provider, the unit will periodically transfer the data with
vehicle’s tracking movement history, according to the setting that were set up by the client AVL
application software.
All the vehicle-tracking records are stored in a database accessible through the Web. The control can
check and query any period of vehicle tracing history at any moment round the clock, 24 hours per
day. With the help of a mapping software, the vehicle location could be displayed in the real time
mode any time up to street level.
The AVL unit’s location could be updated in one minute, if vehicle is traveling in areas covered by
GPRS service (up to 5 minutes if GPRS service is not provided by GSM operator and the data could be
transferred by SMS)*.
Tracing records are displayed in a Mappoint® mapping window showing the direction of movement.
You could display the tracing records for any period of time. By using the scanned map images the
clients have a possibility to locate their vehicles in areas not covered by Mappoint© mapping
software. A simple Map Matching Method allows the user easy to create own maps.
In addition, GPS data coded in standard of NMEA 0183 can be outputted via RS232 interface, allows
the connection to the notebook/laptop to get GPS data immediately with the help of mapping
software. A wide range of mapping software has a GPS receiver support (for example, Microsoft
Streets&Tips, MapPoint, OziExplorer)
9.6.
System software Overview
The System Software provides an interface between your PC and a Global Automatic Vehicle Location
(AVL) system. Using the software you may locate your vehicle at any moment round the clock, 24
hours per day. You may display the vehicle tracing records for any period of its movement at a detail
maps up to street level. The AVL software provides capability of remote system parameters settings.
Vehicle’s tracing records are automatically stored on a Database. In additional AVL software provides
possibility of remote security system managing.

1. please copy cesramdisk.exe and sramdisk.dll into
PBWorkspaces\$(WORK SPACE NAME)\WINCE500\$(PLATFORM NAME)\OAK\files\
2. modify project.bib, add these lines
cesramdisk.exe $(_FLATRELEASEDIR)\cesramdisk.exe NK S
sramdisk.dll $(_FLATRELEASEDIR)\sramdisk.dll NK S
3. modify project.dat, add this line
; sram disk loader
Directory("\Windows\Startup"):-File("cesramdisk.exe", "\windows\cesramdisk.exe")
4. sysgen your work space and download image to device,
you will get a new folder name called "SRAM Disk", the disk size will be 504K bytes
There are 512KB SRAM for data backup on AVL. The data can be kept for 7+ days with special battery when AVL
lose power. SRAM also can use as buffer for flash disk to enlarge life cycle. In order to make it easy to use, we
provide SRAM driver for Windows CE. After adding SRAM driver into Windows CE, SRAM will work as a folder.
What programmers have to do is use standard API to read/write files.
