8 4.2. 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". 4.2.1. The Physical Connector FIGURE 4.1 : SAE J1962 connector 4.2.2. The Connector Outline TABLE 4.1 OBD-II Pin Assignment Pin Assignment Pin 2 - J1850 Bus+ Pin 4 - Chassis Ground Pin 5 - Signal Ground Pin 6 - CAN High (J-2284) Pin 7 - ISO 9141-2 K Line Pin 10 - J1850 Bus Pin 14 - CAN Low (J-2284) Pin 15 - ISO 9141-2 L Line Pin 16 - Battery Power FIGURE 4.2 : OBD-II Connector 4.2.3. The Connector Pin Defined FIGURE 1C. shows the pin assignment used incompliant with OBD-II specification. FIGURE 4.3 : OBD-II Connector Pin Defined FIGURE 1. SAE J1962 connector providesaccess to the diagnostic network
9 4.2.4. 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: TABLE 4.2 OBD-II Types Summary SAE J1850 VPW GM GM cars and light trucks: The connectorshould have metallic contacts in pins 2, 4, 5, and 16, but not 10. SAE J1850 PWM Ford The connector should have metallic contactsin pins 2, 4, 5, 10, and 16. ISO 9141-2 Chrysler, all European and most Asian imports The connector should have metallic contactsin pins 4, 5, 7, 15, and 16. ISO 9141 protocol Cadillac and Opel Others like Cadillac Catera and GermanOpel have some variations with theconnector pin assignment. KWP2000 Similar to ISO 9141 protocol Daewoo, Hyundai, KIA, Subaru STi, andsome Mercedes. Dual K-Line that supportsbi-directional and unidirectional L-Linesignal KWP1281 Similar to ISO 9141 protocol with theexception of support for ABS and year 2002+ engines/ transmissions/ airbags Same as above. Dual K-Line that supportsbi-directional and unidirectional L-Linesignal CAN CAN is widely used in European vehicles and North American manufacturers. By strategy, newer GM vehicles is entirely based on the CAN protocol: GMLAN. Like J1939, OBD-II, J1587 & LIN: GMLAN is a higher level protocol (HLP) that is implemented on top of the hardwarein software either on the host or the device hardware itself (firmware). 2004 and newer Ford, Jaguar, Mazda,Mercedes, Nissan, and Toyota. GMLAN:CAN operates at speeds up to 1 Megabit -this is 100 times faster than a J1850 VPWnetwork. Note: All the above mentioned article served for the purpose of sharing information as references. The above 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.
10 Chapter 5 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 o Sensor input (different ranges) o Opened/closed doors o Ignition wire B. Outputs o External 433 MHZ RF Antenna o Ignition blockage o Siren output o Central Lock (close and open the doors), o Automotive Parking Lights o External LED o 12V power wires. AVL75 can work independently without security control and other add-on components/parts. It needs no changing of the software, just remove the additional modules from the AVL unit.
11 Chapter 6 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, with other related communication and tracking module in the designated option electronic add-on modules..

18 Chapter 9 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. 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. 9.3.2 New history information broadcast on the windows site. 9.3.3. 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.
19 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. 9.6.1. Installation Minimum System Requirements for AVL software: · Operating Systems: Windows CE/Embedded XP(Recommended); · 166 MHz Intel Pentium processor or equivalent; · 128 MB RAM (recommended); · 32 MB available flash disk space. Note: MapPoint© and OziExplorer© are the copyright of Microsoft and Des Newman respectively.
