Visiontek Protocol GPS Trackers: Technical Comparison & Setup
The Visiontek protocol, commonly associated with Port 5069, is a staple in high-reliability fleet management. Devices like the 84 VT, 86 VT, and VT87 utilize this protocol to deliver precise telematics data. This guide covers their technical differences and essential setup steps.
1. Model Comparison Table
| Feature | 84 VT | 86 VT | VT87 |
|---|---|---|---|
| Primary Focus | Basic Tracking | Fleet Management | Advanced Telematics |
| Protocol / Port | Visiontek / 5069 | Visiontek / 5069 | Visiontek / 5069 |
| I/O Ports | Limited (ACC, Power) | Standard (Digital/Analog) | Expanded (RS232/CAN Support) |
| Backup Battery | 150mAh – 300mAh | 400mAh+ | High Capacity Internal |
2. Technical Wiring Diagram (Standard 4-Wire)
Most Visiontek-based devices follow a standardized color-coding for vehicle installation:
- Red (Power +): Connect to constant 12V/24V DC battery supply.
- Black (Ground -): Connect to the vehicle chassis or battery negative.
- Orange (ACC/Ignition): Connect to the vehicle’s ignition switch to detect “Engine ON” status.
- Yellow (Relay/Cut-off): Connect to a 12V relay to enable remote fuel or starter cut-off.
3. Essential SMS Configuration Commands
To initialize these devices, send the following SMS commands to the SIM card number inside the tracker. Note: Default password is typically 0000 or 123456 depending on factory settings.
A. Set Server IP and Port
Format: adminip+password+space+IP+space+Port
Example: adminip123456 104.248.xxx.xxx 5069
Example: adminip123456 104.248.xxx.xxx 5069
B. Set APN (Cellular Data)
Format: apn+password+space+APNName
Example: apn123456 internet
Example: apn123456 internet
C. Set Reporting Interval
Format: upload+password+space+time(seconds)
Example: upload123456 30 (Sets updates to every 30 seconds)
Example: upload123456 30 (Sets updates to every 30 seconds)
Pro Tip: Always ensure the SIM card has the PIN code disabled and has an active data plan before installation. Use “RCONF” to check the current configuration status via SMS.
4. Troubleshooting Connection (Port 5069)
If the device appears offline in your tracking platform:
- Verify that your server firewall allows traffic on TCP/UDP Port 5069.
- Check if the device has a GPS fix (LED usually solid blue).
- Send a “Check” command (e.g., check123456) to verify GSM signal and GPRS status.
