MTX-Tunnel GPS Tracking: Technical Protocol & Configuration
The MTX-Tunnel series represents a high-end industrial IoT solution for GPS tracking and telemetry. Operating primarily on Port 5083, these devices bridge serial data to cellular networks using the specialized MTX protocol.
1. Comparison Table: MTX vs. Standard Protocols
| Feature | MTX Protocol | GT06 (Standard) | Meitrack |
|---|---|---|---|
| Default Port | 5083 | 5023 | 5020 |
| Data Security | SSL/TLS / IP Filter | None | Basic |
| Logging | 6000+ Records | Limited Buffer | Standard Buffer |
| Gateway Mode | GPRS-to-Serial / I/O | Location Only | Location + I/O |
2. Technical Wiring Diagram (Typical MTX-65+G)
Proper wiring is essential for stable power and ignition sensing. Below is the pinout configuration for the DB15 or terminal block connectors:
[ PIN 2 ] — (GND) — Ground (-)
[ PIN 3 ] — (IGN) — Ignition Sense (Input 1)
[ PIN 4 ] — (OUT) — Digital Output (Relay/Cutter)
[ PIN 5 ] — (TXD) — RS232 Transmit
[ PIN 6 ] — (RXD) — RS232 Receive
3. SMS Configuration Commands
To initialize the device and point it to your server, send the following SMS commands to the device’s SIM card number:
Set APN (Network Provider)
Set Server IP and Port (Port 5083)
Set Tracking Interval (e.g., 60 seconds)
Check Status/Parameters
4. Implementation Summary
When integrating MTX-Tunnel devices into a platform, ensure that your firewall allows traffic through Port 5083. The MTX protocol’s ability to act as a Transparent Tunnel makes it ideal for reading external sensors (Modbus/RS485) while simultaneously sending GPS coordinates.
Note: Always use a SIM card with a data plan and disabled PIN code for initial setup.
