Setup Notes
- Tracker ID: For most PT502 models, the ID is either the full IMEI number or a specific identifier provided by your tracking platform.
- APN Configuration: If your mobile carrier does not require a username or password, you can simply send
<password>APN<APN>(e.g.,000000APNinternet). - Time Intervals: You can set dual reporting intervals to save data. For example,
000000GTI30,0,0,0,240sets the tracker to report every 30 seconds when the ignition is ON and every 2 hours when OFF.
RFID Driver Identification Commands
| Function | SMS Command Format | Example |
|---|---|---|
| Enable RFID Mode | <pwd>RFD1 | 000000RFD1 |
| Disable RFID Mode | <pwd>RFD0 | 000000RFD0 |
| Check Driver ID | <pwd>ASKRFD | 000000ASKRFD |
- Engine Control: When RFID mode is active, the driver must swipe an authorized tag within a set timeframe (usually 5 seconds) after turning the ignition on, or the engine will be cut automatically via the relay.
- Authorized Tags: Tag IDs are typically managed via the tracking platform (FMS), but the
RFD1command is required on the hardware side to begin processing tag data.
Additional Advanced Telemetry
- Fuel Monitoring: Use
<pwd>AD1<10,Fuel Lowto receive a “Fuel Low” alert when the tank level drops below 10%. - Mileage Tracking: Use
<pwd>MLA100000,50000to set an initial 100,000km odometer reading and receive alerts every 5,000km for maintenance.
Choosing the Right Device for Your Fleet
For businesses requiring comprehensive telemetry, the Bofan PT502 stands out due to its ability to integrate with additional sensors for fuel and driver identification. If you prioritize video evidence alongside location data, the AnioSmart A510 dash cam offers a modern 4G solution. Most of these units are fully supported by universal platforms.
