Empowering Every Application

The AT-TCU-5-B-100 is deployed where price optimisation meets regulated compliance, driving scalable transparency for diverse logistics operations and industrial vehicle networks.

Cost-Optimized Logistics & Commercial Fleets

High-volume cargo operations, intra-state delivery trucks, and distribution vehicles require a robust fleet management system with live GPS tracking. The A4T offers a dependable hardware foundation that logs transit status, minimises vehicle power usage via ultra-low standby tracking, and feeds raw positioning records cleanly to back-end mapping portals.

OEM Standard Factory Fitment

Automotive manufacturers looking for a cost-effective, standard-compliant TCU for automotive production lines. Its small form factor, 6-pin automotive connection, and built-in CAN UDS diagnostics make it an ideal, factory-installed telematics engine for entry-level consumer and commercial automotive lineups.

Empowering Every Fleet Operation

AT-TCU-5-A-110 pairs a Linux telematics platform with automotive-grade interfaces and secure connectivity. One unit built for the demands of connected fleet management, OEM integration, and regulatory deployment.

Linux-Based Fleet Intelligence

An industrial-grade Linux NAD with eMMC storage up to 64GB gives ACON-4T PRO the processing depth to handle complex fleet data, richer analytics, and faster firmware evolution than standard TCUs.

Secure by Design

Internal HSM with upgradeable external HSM and TLS 1.2 encryption protects every data transmission. Security is built into the hardware, not layered on after.

Multi-Channel Firmware Updates

Firmware updates over HTTPS, RS232, CAN, and RS485 give fleet teams flexible lifecycle management across the entire deployment, with or without depot access.

Rich Interface Integration

Eight digital inputs, dual CAN 2.0, RS232, RS485, and Dallas 1-Wire support connect the sensors and sub-systems a modern fleet depends on, from fuel monitoring to driver behaviour.

Ready for What Comes Next

CAT4, CAN FD, external HSM, and WB-NTN satellite are all upgradeable. The platform grows with the programme instead of being replaced by it.
