1. Introduction
R718PA9 is a Class A device based on the LoRaWANTM protocol of Netvox and is compatible with
LoRaWAN protocol.
R718PA9 can be connected with an ORP sensor (RS485) externally and report the ORP value of the
solution collected by the device to the corresponding gateway.
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
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. On/off interval is suggested to be about 10 seconds to avoid the
interference of capacitor inductance and other energy storage
components.
2. Five seconds after power on, the device will be in engineering
test mode.
Network Joining
Never Join the Network
Turn on the device to search the network.
The green indicator keeps 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.
The green indicator keeps on for 5 seconds: success.
The green indicator remains off: fail.
Fail to Join the Network
Suggest checking the device registration information on the
gateway or consulting your platform server provider if the device
fails to join the network.
Function Key
Press and Hold for 5 Seconds
Restore to the original 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
the device sends a data report
The device is not in the network: the green indicator remains off

5. Data Report
After power on, the device will immediately send a version packet report. Then, it will send
another report with the data of ORP value 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=180s (3min)
MinTime: The MinTime configuration is not available. But the software has restriction, MinTime
must be configured a number greater than 0.
Note:
1.Report interval is based on the factory default.
2.R718PA9 reports the ORP value.
The device reported data parsing please refer to
Netvox LoraWAN Application Command document and Netvox Lora Command Resolver
http://www.netvox.com.cn:8888/cmddoc
Report Con figuration
(1) Configure R718PA9 device parameter MaxTime = 1min (The MinTime configuration is useless,
but it needs to be set greater than 0 because of the software limitation.)
Downlink: 0157000A003C0000000000
Device Return:
8157000000000000000000 (configuration success)

6. Information about Battery Passivation
1. R718PA9 has the built-in magnet (as the
figure below) which can be attached to the
surface of an iron object during installation,
which is convenient and quick.
In order to make the installation firmer, please
use screws (purchased separately) to fix the
device to the wall or other surface (as the
figure below).
Note: Do not install the device in a metal
shielded box or in an environment surrounded
by other electrical equipment to avoid
affecting the wireless transmission of the
device.
2. R718PA9 regularly reports the data of ORP
value according to MaxTime. The default Max
Time is 3 minutes.
Note:
MaxTime can be modified by the downlink
command, but it is recommended not to set the
interval too short.
R718PA9 can be applied to detecting the ORP
value of the solution.
Example:
⚫Water Quality Monitor
⚫Industrial Sewage Disposal
⚫Agricultural Irrigation/Aquaculture
⚫Swimming Pool/Hot Spring

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.
