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
⚫Batteries are at risk of exploding if incorrectly installed.
⚫Do not attempt to recharge, force open, or heat the battery.
⚫Replace the battery only with the same or equivalent type
recommended by the manufacturer.

Service and Maintenance/ ESD Precautions
Service and Maintenance
⚫ONLY qualified personnel should service the system
⚫Shutdown the system, disconnect the power cord and all other connections
before servicing the system
⚫When replacing/ installing additional components (expansion card, memory
module, etc.), insert them as gently as possible while assuring proper
connector engagement
ESD Precautions
⚫Handle add-on module, motherboard by their retention screws or the module’s
frame/ heat sink. Avoid touching the PCB circuit board or add-on module
connector pins
⚫Use a grounded wrist strap and an anti-static work pad to discharge static
electricity when installing or maintaining the system
⚫Avoid dust, debris, carpets, plastic, vinyl and 8tyrofoam in your work area.
⚫Do not remove any module or component from its anti-static bag before
installation
Restricted Access Location
The controller is intended for installation only in certain environments
where both of the following conditions apply:
⚫Access can only be gained by QUALIFIED SERVICE PERSONNEL who have
been instructed on the reasons for restrictions applied to the location and any
precautions that shall be taken

1 Introduction
NRU-220S series is a one-stop AI NVR real-time inference and video transcoder powered by
NVIDIA Jetson AGX Orin. Its fanless design and wide temperature operation capability makes it
ideal for stationary or mobile deployment applications.
NRU-220S
NRU-222S
Powered by NVIDIA® Jetson AGX Orin™32GB/ 64GB system-on-module (SOM), it comprises
an Ampere GPU with up to 2048 CUDA cores, 64 Tensor cores, 2x NVDLA 2.0 Engines that
offer a total of 275 sparse TOPS (INT8) AI inference and video transcoding capability of up to
twenty-two 1080P video streams simultaneously.
NRU-220S offers four 802.3at PoE+ ports sharing 1 Gigabit bandwidth; each port can supply up
to 25.5W of power to IP cameras. The additional two 2.5GbE ports is ideal for surveillance
applications requiring more IP camera connections, or higher bandwidth connections to the
backend. In addition to 64GB eMMC on the Orin module and an M.2 2280 NVMe socket for fast
SSD read/write, NRU-220S is equipped with two front-accessible 2.5" SSD trays for storage
expansion. It also has two mini-PCIe sockets for CAN/ COM/ WiFi modules and one M.2 B key
socket for 4G LTE/ 5G NR mobile communications.
In addition to the above mentioned connectivity, the system also includes a wide range of
NVIDIA AI tools, and modern deep learning frameworks. NRU-220S brings real-time video
inference to the edge for surveillance, predictive maintenance, and intelligent transportation
system (ITS) applications. Furthermore, with Neousys' unique damping bracket design, ignition
power control, and 8-48V wide-range DC power input, NRU- 220S is also ideal for in-vehicle
deployment. Last but not least, NRU-220S comes with a derivative model, NRU-222S,
incorporating M12 connectors for applications in shock and vibration environments that require
extreme rugged connections, such as for agriculture, construction, and mining machinery.
NRU-220S series is Neousys' response to edge AI performance demands in a compact form
factor with fanless wide-temperature operation.
