A: OBD and OBDII refer to On-board diagnostics and its upgrade version.
It is a vehicle's self-diagnostic and reporting capability,which gives the vehicle owner or repair technician access to the status of various vehicle sub-systems, including a standardized series of DTCs (Diagnostics Trouble Codes) for remedy purpose.
One popular implementation of OBD is to use the standardized digital communications port (OBD port, which is usually set near the driver seat), to access extra real-time data of vehicles, such as mileage, engine data, fuel consumption etc.
A: OBD GPS Tracker is an innovative product integrating three parts into one mini size device, including GPS tracker, OBD device and 2G/3G/4G communication terminal. The device can be plug-and-play installed into most vehicles, and be powered through OBD port easily.
1. In contrast to other costly and complicated way -- breaking the wire of vehicle (which may lead to invalid of vehicle's warranty).
2. OBD GPS tracker can provide vehicle's positioning function, together with vehicle status monitoring remotely through Telematics service platform.
3. OBD GPS tracker is widely used in below scenarios: fleet management, vehicular monitoring by government, UBI (Usage Behavior Insurance) and other telematics services, etc.
A: 1)OBD GPS tracker for 2G only : 213GD, for global GSM band;
2)OBD GPS tracker for 2G&3G: 213W, for global GSM&WCDMA band:GSM/GPRS 850/900/1800/1900MHz,UMTS/HSPA 800/850/900/1900/2100MHz;
3)OBD GPS tracker for 2G&3G&4G:
213LA for North and South America
213LE for Europe, South East Country like Malaysia, Singapore, Thailand
213LC for China and other most Asia countries.
A: Yes, all of Sinocastel OBD GPS tracker serial products support SIM card (Micro size).
A: 1) Receive the device;
2) Connect it to computer use USB cable that supports data transmission;
3) Download PCTOOL and driver (software) from website (http://www.sinocastel.com/resources/support/), and install the driver according to product type;
4)Set APN and configuration data.The defaulted working mode is passenger.If you need to install the device to commercial vehicle,please change the working mode to heavy duty;
5) Remove the device from computer;
6) Plug it into the OBD port of vehicle and start the engine immediately;
7) The device starts to work immediately, and transmit selected data to the Telematics Service Platform (TSP), assuming the interoperation has been passed already.

Note:Sinocastel also provides a test account of demo system for our customer to test the device. It will be provided upon sample device is delivery.
A: Current OBD GPS tracker 213L and E-car GPS tracker EV228L can support A-GPS, but for this feature, the platform should support it.
A: The standard OBD II protocol hasn't defined this PID yet, the mileage is calculated by vehicle speed*time if the passenger support to read vehicle speed. It's calculated by GPS if it can’t support to read vehicle speed.
A: The accuracy is about 2%; it's related with the vehicle model.
A: The fuel consumption is calculated by the default reported PIDs.
For passenger: Priority level: MAF (0x2110)>MAP(0x210b), IAT(0x210f)
For heavy duty: J1939, Priority level: Total Fuel Used (0x00fa)>(Fuel Economy (0x00b8), Fuel Rate (0x00b))> Fuel Economy (0x00b8)> Fuel Rate (0x00b7)
J1708, three priority level: Total Fuel Used (0x1fa0)>(Fuel Economy(0x1b80), Fuel Rate(0x1b70))> Fuel Economy(0x1b80)> Fuel Rate(0x1b70)
Note: It can’t support to calculate fuel consumption if OBD device communicate with vehicle ECU failed.
A: Set the fuel type as diesel b, and set the engine capacity as correction factor according to the PC Tool manual.
