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.
