Safety Precautions
Safety Precautions
⚫Read these instructions carefully before you install, operate, or transport the
system.
⚫Install the system or DIN rail associated with, at a sturdy location
⚫Install the power socket outlet near the system where it is easily accessible
⚫Secure each system module(s) using its retaining screws
⚫Place power cords and other connection cables away from foot traffic. Do not
place items over power cords and make sure they do not rest against data
cables
⚫Shutdown, disconnect all cables from the system and ground yourself before
touching internal modules
⚫Ensure that the correct power range is being used before powering the device
⚫Should a module fail, arrange for a replacement as soon as possible to minimize
down-time
⚫By means of a power cord connected to a socket-outlet with earthing connection
⚫This product is intended to be supplied by a Listed Power Adapter or DC power
source, rated up to 5000m altitude operation. If further assistance is required,
please contact Neousys Technology
⚫If the system is not going to be used for a long time, disconnect it from mains
(power socket) to avoid transient over-voltage
Battery Warning

1 Introduction
NRU-51V series is a rugged Jetson Orin™NX/ Xavier™NX computer supporting GMSL2
cameras that can act either as a sensor hub or a perception unit for ADAS, teleoperation,
autonomous mobile robots, and autonomous vehicles.
By supporting GMSL2 automotive cameras, they enable NRU-51V+ with greater vision
capability by taking advantage of advanced features such as IP67 waterproof, high dynamic
range (120dB HDR), auto white balance (AWB), and LED flicker mitigation (LFM). NRU-51V+
can obtain high quality images with minimal latency regardless of lighting conditions, from
bright sunny days to pitch-black nights. Moreover, it has a unique synchronization mechanism
capable of acquiring images from four GMSL2 cameras simultaneously within microseconds
channel-to-channel skew. It can further accept GPS PPS signal to align image data with LIDAR
or synchronize cameras on other systems.
Thanks to the great power efficiency of NVIDIA® Jetson Orin NX™NX SOM, NRU-51V+
delivers 100 TOPS inference performance in its 25W power package. Users can transfer raw
camera images through its built-in 10GBASE-T Ethernet to another GPU server for perception
processing, but also leverage its significant TOPS for real-time object or ROI detection. For
teleoperation applications, users can utilize its hardware H.264/265 video codec, to encode
video streams from four GMSL2 cameras in real-time and transmit the live video feed to a
driver at a remote location via 5G telecommunication with minimum latency.
The combination of GMSL2 interface and Jetson Orin™NX makes NRU-51V+ much more than
just a simple edge AI computer. With greater vision brought by automotive cameras plus I/O
interfaces such as 10GbE, CAN 2.0, and M.2 for 5G broadband, NRU-51V+ plays a central role
in a moving platform, as a sensor hub for ADAS, a perception unit for AGV/ AMR, or a
teleoperation controller for off-highway vehicles.
