1. Introduction
1.1 Overview
The TR323 is an industrial mini 5G NR IoT router designed for IoT, M2M, and eMBB
applications requiring higher speed, lower latency data transmission. It provides
OpenWRT based Linux OS embedded environment that allows IoT developers and
engineers to program and install their own applications based on Python, C/C++ to the
hardware.
The TR323 router has 2-Gigabit ethernet ports, 1-RS232(debug), 2-RS485, to connect to
ethernet and serial controllers, sensors, transferring the data to the cloud server via
5G/4G LTE cellular network. It comes with industrial protocols, such as MQTT, Modbus
RTU/TCP, JSON, TCP/UDP, OPC UAand VPN to provide you an efficient and secure IoT
data connectivity between field devices and cloud server.
The TR323 router supports dual sim for failover, providing robust and reliable wireless
and wired connectivity for your mission-critical industrial applications, and GNSS to track
your remote assets, such as EV charging station, solar power, smart pole, smart cities,
smart office, smart buildings, smart traffic light, digital signage advertising, vending
machines,ATM, etc.
