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

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
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 Netvox LoraWAN Application Command document and Netvox Lora Command Resolver http://loraresolver.netvoxcloud.com:8888/page/index

Installation
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
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.
Example: Liquid Depth Monitor
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.
