Introduction 

The 

RTCU NX-910

 is the most advanced industrial IoT Gateway product available on the market 

today.

 

The device is based on the new 

NX32L

 (NX32 for Linux) architecture, which embraces many new 

technologies and, at the same time, maintains full backward compatibility, which ensures already 
implemented and tested NX32 applications can execute without changes.

 

The 

RTCU NX-910

 is designed to meet the ever-increasing challenges on security, in that it offers 

full TLS on all major protocols and includes a hardened protected execution environment with 
dual-boot and automatic fallback and recovery.

 

The 

RTCU NX-910

 device is an industrial-grade device that is designed from the ground up for 

professional M2M / IoT applications with its strong on-board I/O capabilities and multiple com-
munication interfaces such as LTE, Ethernet, dual RS232, dual RS485, and 1-Wire.

 

The on-board I/O system can be expanded almost indefinitely and completely transparently by 
adding Modbus I/O modules.

 

The 

RTCU NX-910

 is, to a certain extent, fully software and hardware compatible with the 

RTCU 

AX9 encore 

and the

 RTCU AX9 turbo

.

 

The advanced power-management features on the 

RTCU NX-910

 combined with the on-board 

high-capacity Li-Ion battery allows the device to stay in a power-saving mode for a longer period 
still being connected to the cellular network and capable of waking up on for example cellular ac-
tivity, change of digital inputs or a vibration sensor

 

This manual contains technical documentation on the installation and usage of the 

RTCU NX-910

 

device. For detailed information on the programming and software configuration of the product, 
please refer to the RTCU IDE documentation. 
 
For detailed information on the powerful RTCU M2M Platform, please refer to the  

RTCU M2M Platform datasheet

 and the RTCU IDE documentation.
