Chapter 2 Installation
2.1 Overview
5G industrial routers must be installed correctly to achieve the designed
functions. Usually, the installation of the equipment must be carried out under
the guidance of qualified engineers approved by the company.
Note ：
Please do not install 5G industrial routers with power on.
2.2 Packing List
5GIndustrial router host 1
Wireless cellular antennas (SMA male) 4
WIFI Antenna (SMA female) 2
Power adaptor 1
Ethernet cable 1
Product Warranty card 1
2.3 Installation and cable connection
Size：
The dimensions are shown in the figure below.
Antenna installation:
The 5G antenna interface is an SMA female socket (identified as "ANT-1",
"ANT-2", "ANT-3", "ANT-4"). Screw the SMA male of the matching wireless
cellular antenna to the antenna To increase the isolation of the 5G antenna, try
to keep the antenna at an angle of 30 degrees to enhance the signal quality. As

NR120 5G Router User Manual

shown below
The WIFI antenna interface is an SMA male socket (identified as "WIFI-1",
"WIFI-2"). Screw the SMA female connector of the supporting WIFI antenna to
the antenna interface, and make sure that it is tightened. In addition, it is
necessary to increase the WIFI antenna. For isolation, it is recommended that
the two wifi be placed at a 90 degree angle.
SIM/UIM card installation：
When installing or removing the SIM/UIM card, first use a screwdriver to
unscrew the M3 screw on the SIM card baffle, remove the baffle, and gently
press the SIM card in with a suitable sharp object to realize the card ejection and
installation. When installing, make sure that the metal contact surface of the
SIM/UIM card faces the correct direction (SIM1 position: the missing corner is
inward, and the metal surface is downward; SIM2 position: the missing corner
is inward, and the metal is facing upward), make sure it is inserted in place, and
then lock the baffle.

2.4 Power instruction
5G industrial routers are usually used in complex external environments. In
order to adapt to the complex application environment and improve the working
stability of the system, the router adopts advanced power supply technology.
Users can use the standard 12VDC/1.5A power adapter to power the 5G
industrial router, or directly use the DC 9~36V power supply to power the router.
When the user uses an external power supply to power the router, the
stability of the power supply must be ensured (the ripple is less than 300mV,
and the instantaneous voltage does not exceed 36V), and the power supply
must be greater than 8W.
It is recommended to use the standard 12VDC/1.5A power supply.
2.5 Indicator

and the yellow light has no indication.
2.6 Reset button description
The 5G industrial router has a reset button, marked as "RST". The function of
this button is to restore the parameter configuration of the 5G industrial router to
the factory value.
The method is as follows: Insert a pointed object into the "RST" hole, and gently
press and hold the reset button for about 15 seconds and then release. At this time,
the 5G industrial router will automatically restore the parameter configuration to the
factory value, and in about 10 seconds After an hour, the 5G industrial router
automatically restarts (the automatic restart phenomenon is as follows: the
"System" indicator turns off for about 10 seconds, and then it works normally).

Most users will be able to configure the Router and get it work properly using
only the settings on this screen. Some Internet Service Providers (ISPs) will
require users to enter specific information, such as User Name, Password, IP
Address, Default Gateway Address, or DNS IP Address. These information can
be obtained from your ISP, if required.

This function is used to detect whether the Internet connection is active, if users
set it and when the Router detect the connection is inactive, it will redial to
users' ISP immediately to make the connection active. If the network is busy or
the user is in private network, we recommend that Router mode will be better.
Detection Method:
None: do not set this function
Ping: Send ping packet to detect the connection, when choose this method,
users should also configure "Detection Interval", "Primary Detection
Server IP" and "Backup Detection Server IP" items.
Route: Detect connection with route method, when choose this method,
users should also configure "Detection Interval", "Primary Detection
Server IP" and "Backup Detection Server IP" items.
PPP: Detect connection with PPP method, when choose this method, users
should also configure "Detection Interval" item.
Detection Interval: time interval between two detections, unit is second
Primary Detection Server IP: the server used to response the Router’s
detection packet. This item is only valid for method "Ping" and "Route".
Backup Detection Server IP: the server used to response the Router’s
detection packet. This item is valid for method "Ping" and "Route".
Note: When users choose the “Route” or “Ping” method, it’s quite
important to make sure that the “Primary Detection Server IP” and “Backup
Detection Server IP” are usable and stable, because they have to response the
detection packet frequently.
Force reconnect: this option schedules the pppoe or 3G reconnection by killing
the pppd daemon and restart it.
Time: needed time to reconnect
STP
STP (Spaning Tree Protocol) can be applied to loop network. Through certain

automatically assigns an IP address for each computer in the network. If they
choose to enable the Router's DHCP server option, users can set all
the computers on the LAN to automatically obtain an IP address and
DNS, and make sure no other DHCP server in the network.
