NT-RTU-2024
NT-RTU-2024
Embedded 4G Router, 2 Ethernet + Wi-Fi + 1 SIM + 1 RS232/RS485
The NT-RTU_2024 is a fully featured embedded 4G router targeted at applications such as EV Charging, traffic signs, vending machines, medical instrumentation, industrial instrumentation and many more IOT-type applications. An embedded router solves two problems that traditional routers do not - cost and size.
The NT-RTU_2024 is a cost-effective small footprint board with Ethernet WAN, Wi-Fi WAN and 4G WAN interfaces that can all be independently configured in the powerful onboard Operating System.
Features
- Small footprint powerful 4G Modem – fully customizable in software
- Dual Ethernet, Wi-Fi (AP and client) and 4G/3G/2G capability
- RS232 (default) or RS485 port for connection to serial devices + integrated Modbus gateway
- Fully programmable Linux environment with excellent SDK Documentation
- Can be connected directly to Raspberry Pi or similar low cost embedded PC for internet access
- Bulk packaging + shipping options to minimize addition to customer BOM cost

Introduction
The NT-RTU_2024 is a fully featured embedded 4G router targeted at applications such as EV Charging, traffic signs, vending machines, medical instrumentation, industrial instrumentation and many more IOT-type applications. An embedded router solves two problems that traditional routers do not – cost and size.
The NT-RTU_2024 is a cost-effective small footprint board with Ethernet WAN, Wi-Fi WAN and 4G WAN interfaces that can all be independently configured in the powerful onboard Operating System.
NT-RTU_2024 is a Linux based router operating system that offers functionality that could take a software engineer many months to write and even more months to adequately test. Key features of NT-RTU_2024 include: VPN – innovative use of Open VPN tunneling to provide a fixed IP address on the router anywhere
RCMS – Robustel’s Cloud management platform – essential for managing an estate of routers – can be OEM branded
SMS Control – total control of the router using SMS for general status or fixing fault conditions with IP Comms
Automated failover – configure the router to automatically fail from WAN/Wi-Fi to 4G with just a few clicks
