02 · Customer Deployment
A Central Interface for Fleet Control and Telemetry
The Danish system integrator required a compact industrial computer to connect vehicle-side data, serial equipment and higher-level control or telemetry software. The project did not rely on unrelated AI workloads or generic compute claims.
Vehicle interfaces
CAN and serial connectivity for vehicle-side data, controllers and telemetry equipment.
Compact integration
A fanless x86 computer with accessible I/O for installation in a constrained vehicle-control space.
Mechanical retention
Solid-state storage, secure mounting and enclosure design appropriate to the project’s vibration environment.
03 · Platform Selection
Why the Project Used AX-234BT
AX-234BT combined x86 compute performance, industrial I/O and a compact fanless enclosure suitable for vehicle integration. Selection did not imply universal protection against every vehicle transient.

04 · Vehicle Integration
Power, CAN and Serial Boundaries Were Defined Separately
Vehicle Power Architecture
The 9–36V DC input supports normal 12V and 24V vehicle operating ranges. Crank, load-dump and conducted-transient qualification must be validated separately against the required electrical profile.
Vehicle power designCAN Termination
With power removed, two 120Ω endpoint resistors typically measure approximately 60Ω across CANH and CANL. This is a bus diagnostic, not a feature or rating of the computer.
CAN 60Ω checkIsolation and Serial Data
Any isolation rating remains configuration-specific. Isolation does not replace termination, grounding or transient protection. RS-232/422/485 carries digital data; analog sensors require a conversion stage.

Production validation is recorded separately from field performance.05 · Factory Validation
What Was Checked Before Shipment
Each supplied unit passed production burn-in and full I/O verification. Test duration and configuration remain tied to the controlled manufacturing record; temperature-chamber testing is treated as a separate qualification activity.
01
Production burn-in
Sustained CPU, memory and storage operation on the shipped configuration.
02
Interface verification
Functional communication and data-integrity checks for configured CAN, serial, Ethernet, USB and display interfaces.
03
Traceability
Configuration and test status associated with the production unit.

Engineering FAQ
Technical Q&A — AX-234BT for Heavy-Duty Fleet Deployment
How does the system handle sudden vehicle engine shutdowns without corrupting the OS?
The AX-234BT features integrated power ignition management. It senses the vehicle's ignition state (ACC) and triggers a graceful software shutdown via the OS before physically cutting hardware power. This mechanism effectively prevents file system damage, SSD corruption, and data loss during sudden engine-offs.
Can the hardware reliably cold-start during sub-zero winter mornings in Denmark?
Yes. The motherboard strictly utilizes industrial-grade ICs and capacitors rated for an operating temperature threshold of -40°C to 70°C. This guarantees safe, immediate cold boots in extreme winter conditions without relying on failure-prone active heating elements.
Standard storage drives fail under MIL-STD-810G shock profiles. How is data retention secured?
Mechanical failure is eliminated by exclusively utilizing industrial-grade NVMe or SATA SSDs. Furthermore, the storage modules are secured using conformal coating and anti-vibration standoffs, ensuring continuous read/write operations even during high-impact events like waste management loading cycles.
What expansion options are available for fleet tracking and real-time telemetry?
The board provides dedicated M.2 Key B and Key E slots with dual SIM card support, allowing seamless integration of 4G/5G cellular modules and high-precision GNSS/GPS. This dual-SIM architecture ensures network carrier redundancy for continuous telemetry streaming across remote logistics routes.
Can the AX-234BT interface simultaneously with modern IP cameras and legacy mechanical sensors?
Absolutely. The single-sided I/O layout includes dual 2.5GbE RJ45 ports for high-bandwidth IP cameras or LiDAR, alongside 4000V isolated RS232/422/485 serial interfaces to collect analog data directly from legacy mechanical scales and valve sensors on heavy-duty trucks.
Fleet hardware upgrades are costly. How does BITECH mitigate End-of-Life (EOL) integration risks?
The AX-234BT leverages Intel's embedded roadmap, which guarantees a minimum 10-year hardware lifecycle. Additionally, we enforce strict BOM (Bill of Materials) locking. This ensures that system integrators will not face unexpected component changes that could require costly firmware recertification or mechanical redesigns years after initial deployment.
