1. Introduction

R718PA9 is a ClassA device based on the LoRaWAN open protocol of Netvox and is compatible

with LoRaWAN protocol.

R718PA9 can be connected with an ORP sensor (RS485), and report the ORP value of the solution

collected by the device to the corresponding gateway. The device is compatible with 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

On/Off

Power On

DC12V adapter

Turn On

Press and hold the function key for 3 seconds till the green

indicator flashes once.

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. Remove and insert the battery, and then the device is at off

state by default.

2. On/off interval is suggested to be about 10 seconds to avoid

the interference of capacitor inductance and other energy

storage components.

3. 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 in the original 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, and then send another

report with the data of ORP value after 20 seconds.

The device sends data according to the default configuration before any other configuring.

MaxTime: Max Interval=3600s (60min)

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

6. Information about Battery Passivation

Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride)

batteries that offer many advantages including low self-discharge rate and high energy density.

However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a

reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the

storage temperature is too high. This lithium chloride layer prevents rapid self-discharge caused by

continuous reaction between lithium and thionyl chloride, but battery passivation may also lead to

voltage delay when the batteries are put into operation, and our devices may not work correctly in

this situation.

As a result, please make sure to source batteries from reliable vendors, and the batteries should be

produced within the last three months.

If encountering the situation of battery passivation, users can activate the battery to eliminate the

battery hysteresis.

*To determine whether a battery requires activation

Connect a new ER14505 battery to a 68ohm resistor in parallel, and check the voltage of the circuit.

If the voltage is below 3.3V, it means the battery requires activation.

*How to activate the battery

1) Connect a battery to a 68ohm resistor in parallel

2) Keep the connection for 6~8 minutes

3) The voltage of the circuit should be ≧3.3V

Note:

Please do not disassemble the device unless it is required to replace the batteries.

Do not touch the waterproof gasket, LED indicator light, function keys when replacing the batteries.

Please use suitable screwdriver to tighten the screws (if using an electric screwdriver, it is

recommended to set the torque as 4kgf) to ensure the device is impermeable.

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.
