1. Introduction
R718PA11 is a ClassA device based on the LoRaWANTM protocol of Netvox and is compatible
with LoRaWAN protocol.
R718PA11 can be connected with a liquid level sensor (RS485) and report the value of the liquid
level 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 manufacturer

4. Set Up Instruction
On/Off
Power On
DC 12V 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. 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 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 to check 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 the value of the liquid level 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 = 3min = 180s
MinTime: The MinTime configuration is not available.
*But the software has restriction, MinTime must be configured a number greater than 0.
Note:
Report interval is based on the factory default.
R718PA11 reports the value of the liquid level.
The device reported data parsing please refer to

6. Installation
1. R718PA11 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 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. R718PA11 regularly reports the data of the
liquid level 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.
R718PA11 can be applied to detecting the
liquid level.

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.
