1. Introduction

R718DB2 is a 2-way long-range wireless spring-loaded vibration device for Netvox ClassA-type devices based on the

LoRaWAN open protocol and 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 screwdriver to open)

Turn on Press and hold the function key for 3 seconds and the green indicator flash 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 Batteries.

Note:

1. Remove and insert the battery; the device is at off state by default.

2. On/off interval is suggested to be about 10 seconds to avoid the interference of

capacitor inductance and other energy storage components.

3. For the first 5 second after powering on, the device will be in engineering test mode.

Network Joining

Never joined the network

Turn on the device to search the network to join.

The green indicator stays on for 5 seconds: success

The green indicator remains off: fail

Had joined the network

Turn on the device to search the previous network to join.

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)

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 20 times: success

The green indicator remains off: fail

Press once The device is in the network: the green indicator flashes once and sends a report

The device is not in the network: the 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.

per Min Interval

Report

per Max Interval

The device will immediately send a version packet report and the vibration report data.

The device sends data in the default configuration before any configuration is done.

Default setting:

Max Interval: 0x0E10 (3600s)

Min Interval: 0x0E10 (3600s)

BatteryVoltageChange: 0x01 (0.1V)

R718DB2 Trigger:

When the sensor senses the vibration and the spring deforms, an alarm message will be reported.

The vibration is “1”.

No vibration is “0”.

The vibration Restore Configuration

The Restore function is used to send the final static status of the device.

(Please refer to the configuration command format below.)

Restore = 0, no data will be sent when the device is rest.

The data is sent with the next report.

Restore = 1, the data will be sent with a vibration bit-- 0 after the device is rest for 5 seconds.

Note:

1. The function of Restore is supported by the firmware version after 2020/05/18 version.

2. The device report interval will be programmed based on the default firmware which may vary.

3. The interval between two reports must be the minimum time.

Tips

1. Battery Voltage:

The voltage value is bit 0 ~ bit 6, bit 7=0 is normal voltage, and bit 7=1 is low voltage.

Battery=0xA0, binary=1010 0000, if bit 7= 1, it means low voltage.

The actual voltage is 0010 0000 = 0x20 = 32, 32*0.1v =3.2v

2. Version Packet:

When Report Type=0x00 is the version packet, such as 013D000A0B202005200000, the firmware version is 2020.05.20

3. Data Packet:

When Report Type=0x01 is data packet.

Recalculate MaxTime.

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. It can be attached to the iron surface, or the two ends can be fixed to the wall with

screws.

1. The figure shows the vibration sensor (R718DB2)

applied to the scene of the mousetrap in the restaurant.

It can also be applied to the following scenarios:

Restaurant (rat)

Shopping mall supermarket (rat)

Engine room (rat)

When it is necessary to detect whether the object is

vibrating or moved.

2. Fix the vibration sensor of the vibration sensor on the

object that needs to be detected whether it is vibrating

(Take the mousetrap as a picture, as shown below).

3. When the sensor senses the vibration and the spring deforms, an

alarm message will be reported.

The vibration is “1”.

No vibration is “0”.
