Frequently Asked Technical Questions
Key answers for fleet managers, IoT architects, and operations directors.
Does the system satisfy strict WHO Good Distribution Practice (GDP) audits?
Yes. All data logs are recorded with cryptographic timestamps and stored in immutable cloud storage complying with WHO GDP Technical Report Series 961 and Annex 9 standards.
How does the driver know if a temperature excursion occurs while on the highway?
The system triggers an audible in-cab buzzer, flashes warning LEDs on the dashboard display terminal, and sends SMS and WhatsApp alerts to both driver and logistics control room simultaneously.
Can the telematics unit read engine fault codes from Thermo King and Carrier reefers?
Yes. Our gateway interfaces directly with Thermo King (TG-VI, SR-2, SR-3, SR-4) and Carrier (DataCOLD, Vector, APX) microprocessors via RS-232/RS-485 serial ports to monitor setpoint, return air temp, compressor discharge pressure, and alarm codes.
What happens when a refrigerated truck loses cellular signal in remote valleys?
The onboard sensor pods continue sampling temperature every 60 seconds into non-volatile flash memory. As soon as cellular connection is restored, all backlogged data packets are synchronized without any data gaps.
Can we divide a trailer into frozen and chilled compartments with separate alerts?
Yes. The system supports multi-zone tracking with up to 16 wireless BLE sensors assigned to separate thermal compartments (e.g., -20°C for frozen meats and +4°C for fresh dairy) with distinct escalation thresholds.
