1. Introduction
R718PA2 is a Class A device based on the LoRaWANTM protocol of Netvox and is compatible with
the LoRaWAN protocol.
R718PA2 can be connected with a nitric oxide Sensor (RS485) externally to report the concentration
of nitric oxide collected by the device to the corresponding gateway. The device is compatible with
the LoRaWAN protocol.
LoRa Wireless Technology:
LoRa is a wireless communication technology dedicated to long distance and low power
consumption. Compared with other communication methods, LoRa spread spectrum modulation
method greatly increases to expand the communication distance. Widely used in long-distance,
low-data wireless communications. For example, automatic meter reading, building automation
equipment, wireless security systems, industrial monitoring. Main features include small size, low
power consumption, transmission distance, anti-interference ability and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure
interoperability between devices and gateways from different manufacturers.

4. Set Up Instruction
Network Joining
Function Key
On/Off
Power on DC12V adapter
Turn on DC12V power supply, the green indicator flashing once means turn on
successfully.
Turn off
(Restore to factory setting)
Press and hold the function key for 5 seconds and the green indicator
flashes 20 times.
Power off Remove DC12V adapter.
Note:
1. The first 5 seconds after power on, the device will be in engineering
test mode.
2. On/off interval is suggested to be about 10 seconds to avoid the
interference of capacitor inductance and other energy storage
components.
Never joined the network
Turn on the device to search the network to join.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Had joined the network
(Not restore to the factory setting)
Turn on the device to search the previous network to join.
The green indicator stays on for 5 seconds: success
The green indicator remains off: fail
Fail to join the network Suggest to check the device verification information on the gateway
or consult your platform server provider.
Press and hold for 5 seconds
Restore to factory setting / Turn off
The green indicator flashes 20 times: success
The green indicator remains off: fail
Press once
The device is in the network: the green indicator flashes once and sends
a report
The device is not in the network: the green indicator remains off

5. Data Report
The device will send a version package report immediately after power-on. Then, it will send a report
data with the concentration of nitric oxide after it is powered on for 20s.
The device sends data according to the default configuration before any other configuring.
Default setting:
MaxTime: Max Interval = 3min = 180s
MinTime: The MinTime configuration is not available.
*But the software has restriction, MinTime must be configured a number greater than 0.
Note:
1. The cycle of the device sending the data report is according to the default.
2. R718PA2 reports the concentration of nitric oxide.
Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver
http://loraresolver.netvoxcloud.com:8888/page/index to resolve uplink data.

(1) Configure the report MaxTime = 1min (The MinTime configuration is useless, but it needs to be
set greater than 0 because of the software limitation.)

6.Installation
2. The device periodically reports the data
according to Max Time. The default Max
Time is 3min.
Note: Max Time can be modified by the
downlink command, but it is not
recommended to set this time too short.
1. The device has a built-in magnet (as the figure
below). It can be attached to the surface of an iron
object conveniently and quickly when it is installed.
In order to make the device installation more secure,
use screws (purchased) to fix the device to the wall or
other surface (such as the installation diagram). The
device is screwed by two screws in the middle
(purchased by users).
Note: Do not install the device in a metal shielded box
or in an environment with other electrical equipment
around it to avoid affecting the wireless transmission
of the device.
3. The device can be used in scenarios such
as:
Industrial sites, petroleum and
petrochemical plants, chemical plants,
smelters, indoor air quality inspection,
environment monitoring (atmospheric
monitoring), tobacco companies, etc.

7.Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
• Keep the equipment dry. Rain, moisture and various liquids or water may contain minerals that can
corrode electronic circuits. In case the device is wet, please dry it completely.
• Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic
components.
• Do not store in excessive heat place. High temperatures can shorten the life of electronic devices,
destroy batteries, and deform or melt some plastic parts.
• Do not store in excessive cold place. Otherwise, when the temperature rises to normal temperature,
moisture will form inside which will destroy the board.
• Do not throw, knock or shake the device. Treating equipment roughly can destroy internal circuit
boards and delicate structures.
• Do not wash with strong chemicals, detergents or strong detergents.
• Do not paint the device. Smudges can make debris block detachable parts up and affect normal
operation.
• Do not throw the battery into the fire to prevent the battery from exploding.
Damaged batteries may also explode.
All the above suggestions apply equally to your device, batteries and accessories.
If any device is not operating properly.
Please take it to the nearest authorized service facility for repairing.
