What Is CAN Bus in Fleet Telematics?
CAN Bus (Controller Area Network) is the vehicle communication standard used in commercial trucks, buses, and heavy equipment — including J1939 protocol for engine diagnostics, fuel consumption, speed, and fault codes.
A CAN Bus rugged tablet integrates directly into this network, acting as a real‑time data logger and display terminal. Unlike consumer tablets that require third‑party adapters, our tablet + cradle combination provides hardware‑level dual CAN Bus support (J1939‑compatible), ready for fleet telematics, predictive maintenance, and driver coaching. For system integrators building fleet management tablet solutions, this hardware foundation eliminates the external gateway layer entirely.

Frequently Asked Questions
What CAN Bus data can be collected?
Our CAN Bus tablet supports standard vehicle parameters including engine speed, fuel rate, coolant temperature, oil pressure, fault codes (DTCs), and idle time — compatible with J1939 engine data. Two independent CAN Bus interfaces are supported — ideal for connecting both powertrain and body network simultaneously. Please consult our engineering team for additional channel requirements.
Do I need a separate CAN gateway?
No. The CRD865-CAN cradle integrates CAN Bus hardware directly, eliminating the need for external gateways. This makes the tablet a true in-vehicle data acquisition platform →
Can I log data offline?
Yes. Our tablets support internal storage and SD cards for offline data logging when cellular connection is unavailable — ideal for remote fleet operations and mining sites.
Is OEM customization available for CAN Bus integration?
Yes. We provide SDK, API documentation, and hardware customization for fleet telematics providers and system integrators. Contact CAN Bus team →
