1.Introduction
R718PA10 is a Class A device based on the LoRaWANTM protocol of Netvox and is compatible with LoRaWAN protocol.
R718PA10 can be connected with a turbidity sensor (RS485) externally and report the turbidity value and the temperature 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.

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 the turbidity
value and the temperature of the solution 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. Report interval is based on the factory default.
2. R718PA10 reports the turbidity value and the temperature of the solution.
3. The device reported data parsing please refer to Netvox LoRaWAN Application Command document and
Netvox LoRa Command Resolver http://loraresolver.netvoxcloud.com:8888/page/index

6.Installation
1. R718PA10 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 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. R718PA10 regularly reports the data of the turbidity value
and the temperature of the solution 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.
R718PA10 can be applied to detecting the turbidity and the
temperature of the solution.

Note:
1. The probe contains sensitive optical and electronic components. Make sure that the probe is not subject to severe mechanical
shocks. There are no parts inside the probe that need users’ maintenance.
2. The black plastic cap on the head of the turbidity sensor should be removed during the test; otherwise, it will affect the
measurement.
Maintenance Method
1. External Surface of The Sensor:
Use tap water to clean the external surface of the sensor. If there are still debris remaining, wipe it with a moistened soft cloth.
For some stubborn dirt, users can add some household detergent to the tap water to clean it.
2. Check the Cable of The Sensor:
The cable should not be taut during normal operation; otherwise, the internal wires of the cable may break and the sensor
cannot work normally.
3. Check whether the measuring part of the sensor is dirty, and whether the cleaning brush is normal.

7.Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
• Keep the device dry. Rain, moisture, or any liquid, might contain minerals and thus corrode electronic circuits. If the device gets
wet, please dry it completely.
• Do not use or store the device in dusty or dirty environment. It might damage its detachable parts and electronic components.
• Do not store the device under excessive heat condition. High temperature can shorten the life of electronic devices, destroy
batteries, and deform or melt some plastic parts.
• Do not store the device in places that are too cold. 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. Rough handling of equipment can destroy internal circuit boards and delicate
structures.
• Do not clean the device with strong chemicals, detergents or strong detergents.
• Do not apply the device with paint. Smudges might block in the device and affect the operation.
• Do not throw the battery into the fire, or the battery will explode. Damaged batteries may also explode.
All of the above applies to your device, battery and accessories. If any device is not working properly, please take it to the
nearest authorized service facility for repair.
