Introduction

R718PA 10 is a Class A device based on the LoRaWANT™ protocol of Netvox and is compatible with the LoRaWAN protocol. R718PA 10 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, the 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, and industrial monitoring. The main features include small size, low power consumption, transmission distance, anti-interference ability and so on.
LoRa WAN
LoRaWAN uses LoRa technology to define end-to-end standard specifications to ensure interoperability between devices and gateways from different manufacturers.

Turn On| DC12V power supply, the green indicator flashing once means turn on successfully.
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. The first 5 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 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

Data Report

After powering 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 configuration.

Default Setting

Maxime: Max Interval = 3min = 180s
Min Time: The MinTime configuration is not available.
But the software has a restriction, MinTime must be configured with a number greater than 0.

Note

The report interval is based on the factory default.
R718PA10 reports the turbidity value and the temperature of the solution.
The device reported data parsing please refer to the Netvox LoRaWAN Application Command document and
Netvox LoRa Command Resolver http://www.netvox.com.cn:8888/cmddoc

Installation

R718PA10 has a built-in magnet (as the figure below) that can be attached to the surface of an iron object during installation, which is convenient and quick. 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.

R718PA 10 regularly reports the data of the turbidity value and the temperature of the solution according to Max Time.
The default Max Time is 3 minutes.

Note
Max Time can be modified by the downlink command, but it is recommended not to set the interval too short.

R718PA10 can be applied to detect the turbidity and the temperature of the solution.

Example

Water Quality Monitor

Note

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.
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

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.
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.
Check whether the measuring part of the sensor is dirty, and whether the cleaning brush is normal.

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.
