KHD Protocol Tracking Devices: Configuration & Installation Guide
Devices utilizing the KHD protocol (standardized on Port 5058) are widely used for professional fleet management due to their high reliability and rich sensor data. This guide provides the technical specifics needed for successful deployment of KG, VT, and T360 series trackers.
1. Hardware Comparison & Applications
| Model Series | Standard Port | Key Features | Best For |
|---|---|---|---|
| KG100 / KG200 | 5058 | Compact, Internal Battery | Basic vehicle tracking |
| VT600 / VT900X | 5058 | Fuel monitoring, 2-Way Audio | Advanced fleet logistics |
| T360 Series | 5058 | High sensor capacity (I/O) | Industrial machinery |
2. Technical Wiring Diagram (General Pinout)
While wire colors may vary slightly by manufacturer, the following represents the standard 4-wire to 8-wire harness used for KHD protocol devices like the VT600 or KG series.
- Red (V+): Connect to the positive terminal of the vehicle battery (9V-36V DC).
- Black (GND): Connect to the vehicle chassis or battery negative terminal.
- Orange (ACC): Connect to the ignition wire to detect engine ON/OFF status.
- Yellow (Relay): Connect to the Yellow wire of the relay for remote engine cut-off.
- Green/White (Inputs): Typically used for SOS buttons or door sensors.
3. Essential SMS Configuration Commands
To configure your device, send the following SMS commands to the SIM card number inside the tracker. Note: Default password is usually 000000 or 123456 depending on the sub-brand.
Set Server IP and Port
This tells the tracker where to send the data (use Port 5058 for KHD-compatible servers).
Set APN (Access Point Name)
Required for GPRS data connectivity. Replace ‘internet’ with your carrier’s APN.
Set Tracking Interval (ACC ON)
Sets the device to upload every 30 seconds while the engine is running.
Remote Engine Cut (Relay Control)
Use this command to stop the vehicle in case of theft.
4. Quick Status Troubleshooting
If the device is not showing online on your platform, send the following query command to receive a diagnostic report via SMS:
The device will reply with its current IMEI, GPS signal strength, GPRS status, and Voltage.
For more detailed integration with platforms, ensure the device is identified by its unique IMEI or ID sticker found on the back of the unit.
