1. Introduction

This device is a simple positioning function (which can detect the position status of the device), and

periodically reports RSSI and SNR.

The information is processed by the gateway, and the location range of the device is detected

according to the reported RSSI and SNR information. The device applies SX1276 wireless

communication module. For reported RSSI, SNR information location status, the acceptance

sensitivity is -136 dBm (LoRa, Spreading Factor = 12, Bit Rate = 293 bps).

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.

3. Main Features

Compatible with LoRaWAN protocol.

Powered by 2 x ER14505 3.6V Lithium AA battery

Easy set up and installation

Simple location range detection

4.Set up Instruction

4.1 Power on and Turn on / off

(1) Power on: Insert batteries: open the battery cover; insert two sections of 3.6V ER14505 AA

batteries and close the battery cover.

(2) Turn on: if the device had never joined in any network or at factory setting mode, after powering

on, the device is at off mode by default setting. Press and hold function key for 3 seconds till the

green indicator flashes once and release to turn on device.

(3) Turn off: Press and hold function key for 5 seconds till the green indicator flashes quickly and

release. The green indicator will flash 20 times to show that the device is turned off.

Note:

1. The interval between shutting down twice or power off/on is suggested to be about 10 seconds to

avoid the interference of capacitor inductance and other energy storage components.

2. Do not press function key and insert batteries in the same time, otherwise, it will enter engineer

testing mode.

3. Once the battery is removed, the device is at off mode by default setting.

4. Turn off operation is same with “Restore to Factory Setting”operation.

4.2 Join Into LoRa Network

To join the device into LoRa network to communicate with LoRa gateway.

The network operation is as following:

(1) If the device had never joined any network, turn on the device; it will search an available LoRa

network to join. The green indicator will stay on for 5 seconds to show it joins into the network,

otherwise, the green indicator will be off.

(2) If R718MA had been joined into a LoRa network, remove and insert the batteries; it will repeat

step (1).

4.3 Function Key

(1) Press and hold function key for 5 seconds to reset to factory setting. After restoring to

factory setting successfully, the green indicator will flashes quickly 20 times.

(2) Press function key to turn on the device which is in the network and the green indicator will flash

once and the device will send a data report.

4.4 Data Report

When the device is turned on, it will immediately send a version package.

Data will be reported once per hour by default setting.

Maximum time: 3600s

Minimum time: 3600s (Detect the current voltage value every 3600s by default setting)

Default reportchange:

Battery ---- 0x01 (0.1V)

Note:

The device send data cycle depends on real burning configuration.

The interval between two reports must be the minimum interval.

Data report configuration and sending period are as following:

based on MinTime = 15 Minutes, MaxTime= 1 Hour, battery voltage Reportable Change = 0.1V

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.

5. Restore to Factory Setting

R718MA saves data including network key information, configuration information, etc. To restore to

factory setting, users need to execute below operations.

1. Press and hold function key for 5 seconds till the green indicator flashes and then release; LED

flashes quickly 20 times.

2. R718MA is at off mode by default setting after restoring to factory setting.

Note: The device operation of turning off is the same as the “Restore Factory Settings”operation.

6. Sleeping Mode

R718MA is designed to enter sleeping mode for power-saving in some situations:

(A) While the device is in the network →the sleeping period is Min Interval. (During this

period, if the reportchange is larger than setting value, it will wake up and send a data report).

(B) When it is not in the network →R718MA will enter sleeping mode and wake up every

15 seconds to search a network to join in the first two minutes. After two minutes, it will wake

up every 15 minutes to request to join the network.

If it’s at (B) status, to prevent this unwanted power consumption, we recommend that users

remove the batteries to power off the device.

7. Low Voltage Alarming

The operating voltage threshold is 3.2V. If the battery voltage is lower than 3.2V, R718MA will

send a low-power warning to the LoRa network.

8. 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.

9. 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.
