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.
