STL060 Protocol: The Ultimate Technical Manual
Configuration, Wiring, and Server Integration for Port 5060
1. Introduction to STL060
The STL060 protocol is a high-efficiency communication standard used by modern GPS hardware. Operating primarily on Port 5060, it balances low data consumption with robust features like remote engine cut-off and ACC ignition detection.
2. Mandatory SMS Configuration
Send these commands to the tracker’s SIM card to initialize communication. (Default password: 123456)
| Function | SMS Command Syntax | Expected Response |
|---|---|---|
| Set Server IP/Port | adminip123456 123.123.123.123 5060 | adminip ok |
| Set APN | apn123456 ://operator.com | apn ok |
| Enable GPRS | gprs123456 | gprs ok |
| Factory Reset | begin123456 | begin ok |
| Check Status | check123456 | Lat/Long, Battery, GPRS link |
3. Hardware Installation & Wiring
Power & Ignition Pinout
- Red Wire: Constant Positive (+12V/24V)
- Black Wire: Ground (Negative/Chassis)
- White/Orange Wire: Ignition (ACC) – Triggers “Engine On” status.
- Yellow Wire: Relay Control – Connect to Pin 85 of the relay.
Standard Automotive Wire Colors (Reference)
| Vehicle Function | Common Colors | Notes |
|---|---|---|
| Constant 12V | Red / Yellow | Measure with multimeter (Ignition OFF) |
| Ignition (ACC) | White / Pink | Must show 12V only when key is ON |
| Fuel Pump | Green / Gray | Circuit to be interrupted by relay |
4. 5-Pin Relay Integration (Engine Cut-off)
To enable remote engine stopping, wire the relay as follows:
- Pin 85: Connect to Tracker Yellow Wire.
- Pin 86: Connect to Ignition +12V.
- Pin 30: Connect to “Battery Side” of cut fuel wire.
- Pin 87a: Connect to “Pump Side” of cut fuel wire (Normally Closed).
5. GPS Server Integration
Server Configuration:
1. Log into your tracking platform.
2. Register the device using the 15-digit IMEI found on the sticker.
3. Ensure your server firewall allows traffic on Port 5060 (TCP/UDP).
6. Troubleshooting & Diagnostics
Issue: Device is “Offline” on server.
- Verify SIM card balance and that the PIN lock is removed.
- Check the APN setting. Send check123456 and ensure “GPRS” says “Link Up”.
- Verify the server IP address and port (5060) are correct.
Issue: No GPS signal (0.000, 0.000).
- Ensure the device has a clear view of the sky. Metallic tints on windows can block signal.
- Check if the Blue LED is solid. If flashing fast, it is still searching for satellites.
