User Manual
4.3.3 Vehicle Connection
The method used to connect the SmartLink C device to a vehicle’s DLC depends on the vehicle’s
configuration as follows:
• A vehicle equipped with an OBD II management system supplies both communication and 12V power
through a standardized DLC.
• A vehicle not equipped with an OBD II management system supplies communication through a DLC
connection, and in some cases supplies 12V power through the cigarette lighter receptacle or a
connection to the vehicle battery.
For OBD II vehicles, connect the SmartLink C to vehicle’s DLC port directly via the OBD II extension cable.

4.4 Communication Setup
There are 3 kinds of ways available for the tablet to communicate with the SmartLink C device: Wi-Fi,
Bluetooth and USB cable.
After the sign-up is successfully completed, the Wi-Fi communication between the tablet and the SmartLink
C device is automatically established and user has no need to configure it again.
The Bluetooth communication is inferior to the Wi-Fi communication in transmission speed and stability.
