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
device, wireless security systems, industrial monitoring. 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
The green indicator flashing once: success
Restore to factory setting
Press and hold the function key for 5 seconds until the green indicator flashes 20 times.
Power off
Remove DC12V adapter.
Note
1. 5 seconds after power on, the device will be in engineering test mode.
2. On/off interval is suggested to be about 10 seconds long 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
(without resetting to 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
Please check the device verification information on the gateway or consult your platform server
provider.

Function Key
Press and hold for 5 seconds
Back to factory 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: green indicator remains off
5. Data Report
The device will immediately send a version package after powering on. 20 seconds later, it will send a data report of the noise value.
The device sends data according to the default configuration before any other configuration.
Default setting:
MaxTime: Max Interval = 0xB4 (180s)
MinTime must be greater than 0 due to the software limitation.
Please refer to the Netvox LoRaWAN Application Command and http://www.netvox.com.cn:8888/cmddoc for devices’ data analysis.

Tips
1. Battery Voltage:
If the battery is equal to 0x00, it means that the device is powered by a DC power supply.
2. Version Packet:
When Report Type=0x00 is the version packet, such as 0157000B04202306010000, the firmware version is 2023.06.01
3. Data Packet:
When Report Type=0x01 is data packet.

(1)Configure R718PA7 device parameters
MaxTime = 60s (0x3C)
MinTime must be greater than 0 due to the software limitation.
Downlink: 0157000A003C0000000000
Device returns:
8157000000000000000000 (configuration success)
8157010000000000000000 (configuration failure)
Example:
When the device of R718PA series has more than one data package, the MinTime only represents the interval of two data.
Set MaxTime = 1 min; MinTime = 10s.
(1)The device would report each data at MinTime.
(2) The device has two data (data 1.1 and 1.2), it would report the first one at the beginning; the second one at the 10th second.
(3) After the device reports data 1.1 and 1.2, the next data (data 2.1) will be reported at the 60th second.

6. Installation
Note:
1. The noise sensor should be sent back to factory for calibration or replacement of the probe when it lasts longer than the
lifespan (1 –2 years) and users could not calibrate the errors by themselves.
2. The cables should be connected to the sensor in order. After user fixes the sensor on the wall, the lid should be closed.
3. The sensor should be placed vertically (The words on the sensor should be set right side up). When it is fixed on the wall, the
pickup should be placed under the sensor.
4. The sensor should be installed in the area that users would like to measure.
5. The sensor should be installed in a stable environment. Installation under direct sunlight, near windows, air-conditioners, and
heaters, or directly faced windows and doors could cause inaccurate results.
6. Keep the sensor away from high-power interference devices as far as possible to avoid inaccurate measurements, such as
frequency converter, motor, etc.
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.
3. The device can be used in scenarios such as:
⚫Smart city
⚫Construction site
⚫School
⚫Residential area
1. R718PA7 has a built-in magnet (as the figure below). It can
be attached to the surface of an iron object 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.
