Technical Guide: Orion Protocol GPS Tracking Hardware
The Orion Protocol is a specialized telematics language primarily operating on Port 5070. This guide provides technical installers with the exact wiring and SMS command strings needed to integrate the ET and BD series devices into any GPS platform.
1. Device Comparison & Use Cases
| Model | Mounting Type | Key Application |
|---|---|---|
| Orion ET-100 | Hardwired (4-wire) | General Fleet & Vehicle Security |
| Orion OBDtrac | OBD-II Plug | Diagnostics & Quick Deployment |
| BD-2012 / 3112 | Rugged Hardwired | Industrial Assets & Heavy Machinery |
2. Technical Wiring Diagrams
Orion ET-100 / BD Series (Hardwired)
- Red: Power Positive (+) 9V – 36V DC
- Black: Power Ground (-) Negative
- Orange: ACC / Ignition Sensing (Connect to switch power)
- Yellow: Relay Output (Fuel/Engine Cut-off)
Warning: Always use a multimeter to verify vehicle voltage before connecting the Red wire.
Orion OBDtrac
No wiring required. Plugs directly into the vehicle’s 16-pin OBD-II port. Ensure the device is secured with a zip-tie to prevent it from vibrating loose from the port.
3. Critical SMS Configuration Commands
Most Orion devices use a default password of 0000 or 123456. Replace [password] with your actual device password.
Set Server IP and Port
To point your tracker to a specific server using the Orion protocol on port 5070:
Set APN (Internet Access)
Required for the device to connect to the GPRS network:
Check Status
Retrieve a diagnostic report (Battery, GPS signal, and Network status):
Change Reporting Interval
Sets how often the device sends data (e.g., every 30 seconds):
Summary of Integration
To ensure successful data transmission, verify that your server firewall is open to TCP/UDP Port 5070. For the Orion OBDtrac, ensure the SIM card has “Voice + Data” enabled, as some firmware versions require SMS authorization to start GPRS flow.
