The SmartLink C dongle is a versatile device designed for vehicle diagnostics and remote technical assistance. It functions primarily as a Vehicle Communication Interface (VCI) and a SmartLink Customer dongle, offering comprehensive capabilities for both local and remote diagnostic scenarios.

Function Description:

As a VCI Device:

In this mode, the SmartLink C dongle works in conjunction with the "Diagnose" module of a diagnostic tool. Its primary function is to obtain vehicle data and transmit it to the diagnostic tool for analysis. Communication between the dongle and the diagnostic tool can occur via WiFi, Bluetooth, or USB, depending on the diagnostic tool's hardware capabilities. This setup is essential for local diagnostic operations where the diagnostic tool directly interfaces with the vehicle through the SmartLink C dongle.

As a SmartLink C (Customer) Dongle (for SmartLink Diag.):

This mode is designed for users who require remote technical assistance from master technicians. In this scenario, the SmartLink C dongle does not directly communicate with the diagnostic tool's "Diagnose" module. Instead, it integrates with the "SmartLink" module of the diagnostic tool. The diagnostic tool is used to issue remote diagnostic requests, while the SmartLink C dongle, when networked, receives and executes commands from a remote SmartLink B (Business) dongle operated by a master technician. This enables remote diagnostics, online programming, and other advanced services.

SmartLink Diag. System:

The SmartLink system is a powerful remote diagnostics solution developed by LAUNCH. It comprises:

SmartLink C dongle (Technician/Customer): Used by technicians seeking a second opinion or additional expertise, or by customers requiring remote assistance.
SmartLink Service Platform: Facilitates the posting of assistance requests from SmartLink C and the acceptance of orders by SmartLink B.
SmartLink B dongle (Master Technician/Service Provider): Used by master technicians to provide professional technical services remotely.

The workflow for a SmartLink session involves:

Post Request: The SmartLink C dongle is bound, and a remote diagnostics request is posted via the SmartLink module.
Connection & Setup: The SmartLink C is connected to the vehicle's DLC and a crossover cable, then set to "Remote Diagnostics" mode.
Wait for Partner's Assistance: After a remote master technician accepts the order, they use a SmartLink B dongle and a compatible diagnostic tool to provide technical service.
Start Diagnostics: The ignition key is turned on, and the diagnosis begins. Once completed, the crossover cable is unplugged, the operation is terminated, and the service is rated.

Important Technical Specifications:

Touch Screen: Features a 3.97-inch touch screen for user interaction.
Connectivity:
- OBD-16 Diagnostic Connector: Standard connector for interfacing with vehicle's Data Link Connector (DLC).
- LAN/WAN Port: Used for network connection, especially in "SmartLink" mode, connecting via a crossover cable.
- DC-IN Port: Currently disabled and for manufacturer use only.
- Data I/O Port: Connects data cables.
Power Supply: The SmartLink C dongle obtains power exclusively through the vehicle's DLC. Connecting it to an external DC power supply is strictly prohibited to prevent damage or loss.
Vehicle Battery Voltage Range: Operates within a vehicle battery voltage range of 11-14 Volts or 18-30 Volts.

Usage Features:

WLAN Setup: The device has a built-in WLAN module for internet connectivity. Users can configure WLAN settings, select desired networks, and connect to the internet for registration, software updates, and other online functions.
Registration & Update:
1. App Launch: Access the application icon on the home screen and tap "Login," then "New Registration" to create an account.
2. Account Creation: Input required information (username, password, email, country) and tap "Register."
3. VCI Activation: Input the Product S/N and Activation Code (found in the Password Envelope) to activate the VCI.
4. Software Download: After successful registration, users can download diagnostic software packages. The device automatically installs the software once downloaded. Regular updates are recommended for optimal performance.
Vehicle DLC Location: For passenger cars, the 16-pin DLC is typically located on the driver's side, about 12 inches from the center of the dashboard. For commercial vehicles, it is always in the driver's cab.
Connection Methods:
- OBD II Vehicle Connection: Direct connection to the vehicle's DLC via the diagnostic cable for OBD II equipped vehicles.
- Non-OBD II Vehicle Connection: For non-OBD II vehicles, a non-16pin connector is required, often involving an OBD II extension cable and an OBDI Adaptor.
- Alternative Power Supply: If the vehicle's diagnostic socket has insufficient power or damaged pins, power can be supplied via battery clamps cable or cigarette lighter cable connected to the OBD I adaptor box.
Intelligent Diag: An alternative diagnostic method that streamlines the diagnostic process.

Maintenance Features:

Software Updates: All software is updated periodically. Users are advised to regularly check for updates and install the latest software versions to ensure the best service and functions.
Power Management during SmartLink Diagnosis: During SmartLink diagnosis, especially remote online programming, it is recommended to connect the vehicle battery to a charging power source. This prevents the vehicle from running out of power and failing to start due to prolonged diagnosis times.
Network Stability for Remote Diagnosis: During remote diagnosis, it is crucial not to disconnect the vehicle or the network. A broadband of 100Mb and above is recommended. The dongle can only receive one remote diagnosis operation at a time.
Network Delay Monitoring: The dongle displays network delay (green for normal, yellow for not stable, red for serious delay). It is recommended to perform diagnosis when the network delay is green to avoid communication failures or incorrect system detection.

Safety and Legal Considerations:

Prohibited External Power: Strictly prohibited from connecting to an external DC power supply. LAUNCH assumes no responsibility for damages or losses resulting from non-compliance.
Intellectual Property: LAUNCH owns complete intellectual property rights for the software. Any reverse engineering or cracking actions will result in blocking the product's use and potential legal liabilities.
