Built-in watchdog
ASDU-LS series of intelligent gateways adopt industrial grade NXP Cortex-A7 processor and load a embedded
Linux real-time multitasking operating system. It supports multiple communication protocols and can be applied in large scale demanding integrated automation systems, dispatching automation systems and distribution automation systems.



The Cortex®-A7@CPU adopts 28nm process that reduces power consumption by 80% compared to the previous generation.
256M DDR3L memory, 4GB EMMC storage, up to 32GB TF card expansion.



Pioneering cloud debugging realizes remote configuration, debugging and upgrade;
Programmable communication protocols, Protocol driven Template for batches configuration;
Data buffer once communication interruption, then upload data’s during interruption after communication recovery;
Support storage and management of various documents such as communication messages and data files;
Provide HTTP and MQTT data release;
Hardware and software dual watchdog mechanism ensures stability and reliability.
Configure the terminal template once and for all;
Four-remote data all covered;
Portable personalized custom database files;
Quick configuration for same type terminals in different project sites and various application scenarios.


The simulation demonstration can remotely analyze the data to solve the problem at home, without going and back the site.
