1. Introduction
The R718B series equipment is the temperature detection based on the LoRaWAN open protocol. The external PT1000 measures the temperature and
the device is compatible with the 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 Insert batteries.
(users may need a flat blade screwdriver to open)
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 till green indicator flashes for 20 times.
Power off Remove Batteries.
Note:
1. Remove and insert the battery; the device is at off state by default. Press and hold the function key for 3 seconds till
the green indicator flashes once to turn on the device.
2. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor inductance and other
energy storage components.
3. At 1st -5th second after power on, the device will be in engineering test mode.
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 at factory setting
mode)
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
(when the device is on)
First two mins: wake up every 15 seconds to send request.
After two mins: enter sleeping mode and wake up every 15 minutes to send request.
Note: Suggest to remove batteries if the device is not used to save power.
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 / Turn off
The green indicator flashes for 20 times: success
The green indicator remains off: fail
Press once The device is in the network: green indicator flashes once and sends a report
The device is not in the network: green indicator remains off
Sleeping Mode
The device is on and in the
network
Sleeping period: Min Interval.
When the reportchange exceeds setting value or the state changes: send a data report according to Min Interval.
The device is on but not in
the network
First two mins: wake up every 15 seconds to send request.
After two mins: enter sleeping mode and wake up every 15 minutes to send request.

5. Data Report
The device will immediately send a version package Report and a report data with temperature and voltage values when the device is powered on.
The device sends data in the default configuration before any configuration is done.
Maximum time: Max Interval
Minimum time: Min Interval (by default, the current voltage value and the temperature value are detected every Min Interval)
Default reportchange: batteryvoltagechange ---- 0x01(0.1V)
Temperaturechange ---- 0x01 (0.1°C)
Note: The device send data cycle has been programmed to be correct.
The interval between two reports must be the minimum time
R718B default Max Interval = 60min, Min Interval = 60min
(if there is special custom shipment, the setting is changed according to customer requirements)
The data can be decoded by the Netvox LoraWAN Application Command document and http://www.netvox.com.cn:8888/page/index
Report configuration example:
(1) Configure device parameters MinTime = 1min, MaxTime = 1min, BatteryChange = 0.1v, Temperaturechange = 0.1°C
Downlink: 0195003C003C0100010000
Devices return:
8195000000000000000000 (configuration is successful)
8195010000000000000000 (configuration is failed)
(2) Read device parameters
Downlink: 0295000000000000000000
Devices return:

Notes :
1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data.
2) The data collected is compared with the last data reported. If the data variation is greater than the ReportableChange value, the device reports according to
MinTime interval. If the data variation is not greater than the last data reported, the device reports according to MaxTime interval.
3) We do not recommend to set the MinTime Interval value too low. If the MinTime Interval is too low, the device wakes up frequently and the battery will be
drained soon.
4) Whenever the device sends a report, no matter resulting from data variation, button pushed or MaxTime interval, another cycle of MinTime/MaxTime
calculation is started.

6. Installation
This product comes with waterproof function. When using it, the back of it can be adsorbed on the iron surface, or the two ends can be fixed to the wall
with screws.
Note: To install the battery, use a screwdriver or similar tool to assist in opening the battery cover.
7. Important Maintenance Instruction
Your device is a product of superior design and craftsmanship and should be used with care. The following suggestions will help you use the warranty
service effectively.
•Keep the equipment dry. Rain, moisture, and various liquids or moisture 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 can damage its detachable parts and electronic components.
•Do not store in excessive heat. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts.
•Do not store in a 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. Rough handling of equipment can destroy internal circuit boards and delicate structures.
•Do not wash with strong chemicals, detergents or strong detergents.
•Do not apply with paint. Smudges can block debris in detachable parts and affect normal operation.
•Do not throw the battery into a fire to prevent the battery from exploding. Damaged batteries may also explode.
All of the above suggestions apply equally to your device, battery and accessories. If any device is not working properly.
Please take it to the nearest authorized service facility for repair.
