netvox Wireless Noise Sensor R718PA7 User Manual

1. Introduction

R718PA7 is a Class A device based on LoRaWANTM of NETVOX and is compatible with LoRaWAN protocol.R718PA7 can be connected with a noise sensor (RS485) externally. The noise value
collected by the device will be reported 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

oRaWAN 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.

Restore to factory setting

| Press and hold the function key for 5 seconds till green indicator flashes

20 times.

Power off| Remove DC12V adapter.

Note:

| 1.     5 second after power on, the device will be in engineering test mode.

2.     On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor inductance and other energy storage components.

Network Joining

Never joined the network

| Turn on the device to search the network.

The green indicator stays 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 stays on for 5 seconds: success The green indicator remains off: fail

Fail to join the network

| Suggest to check the device verification information on the gateway

or consult your platform server provider.

Function Key

Press and hold for 5 seconds

| Restore to factory setting

The green indicator flashes for 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: green indicator remains off

5. Data Report

The device will immediately send a version package report. Then, it will send a report data with the noise value after it is powered on for 20s.
The device sends data according to the default configuration before any other configuration.

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. The cycle of the device sending the data report is according to the default.
2. R718PA7 reports the noise value.
   The data parsing reported by the device is referenced by the Netvox LoraWAN Application Command document and http://www.netvox.com.cn:8888/page/index

Example of Configure Cmd

1. Configure R718PA7 device parameters MaxTime = 60s (The MinTime configuration is useless, but it needs to be set greater than 0 because of the software limitation.)
   Downlink: 0157000A003C0000000000
   Device returns:
   8157000000000000000000 (configuration success) 8157010000000000000000 (configuration failure)

2. Read R718PA7 device parameters
   Downlink: 0257000000000000000000 Device returns: 8257000A003C0000000000 (device current parameter)

6. Installation

1. R718PA7 has a built-in magnet (as the figure below). It can be attached to the surface of an iron object conveniently and quickly when it is installed.
   In order to make the device installation more secure, use screws (purchased) to fix the device to the wall or other surface (such as the installation diagram). The device is screwed by two screws in the middle (purchased by users).
   Note: Do not install the device in a metal shielded box or in an environment with other electrical equipment around it to avoid affecting the wireless transmission of the device.

2. The device periodically reports the data according to Max Time. The default Max Time is 3min.
   Note: Max Time can be modified by the downlink command, but it is not recommended to set this time too small to avoid excessive battery drain.

3. The device can be used in scenarios such as:
   Smart city
   Construction site
   School
   Residential area
   

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.
