1. Introduction

R718J is a ClassA external dry contact device based on LoRaWAN open protocol of Netvox. It can externally connect various

switches, buttons, relays and reed switch output. It can detect the closing or disconnecting signal of dry contact and is

compatible with LoRaWAN protocol.

LoRa wireless technology:

LoRa is a wireless communication technology dedicated to long-distance low-power consumption. Its spread-spectrum

modulation method greatly increases the communication distance compared with other communication methods, and can be

widely used in long-distance low-rate IoT wireless communication fields in various occasions. Such as automatic meter

reading, building automation equipment, wireless security systems, industrial monitoring and control. It has the characteristics

of small size, low power consumption, long transmission distance and strong anti-interference ability.

LoRaWAN:

LoRaWAN defines an end-to-end standard specification using LoRa technology to ensure interoperability between devices and

gateways from different vendors.

according to Min Interval.

Low Voltage Warning

Low Voltage

3.2V

5. 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.

Default Setting:

Maximum Time: 0x0E10 (3600s)

Minimum Time: 0x0E10 (3600s) // Detect the current voltage value every 3600s by default setting

Battery Change: 0x01 (0.1V)

LastMessageResendTime: 0x00

Dry Contact Detection Trigger:

When the dry contact is connected, the data status bit is “1”.

When the dry contact is disconnected, the data status bit is “0”.

Last Message Resend Time Function:

Resendtime = 0x00 or 0xFF, send the current dry contact state

Resendtime = 0x03 to 0xFE, send the current dry contact state, and re send the dry contact state after 3-254s

*The function of Resendtime is supported by the firmware version after 2020/05/13 version

Note:

The device send data cycle depends on real burning configuration.

The interval between two reports must be the minimum interval.

Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver

http://www.netvox.com.cn:8888/cmddoc to resolve uplink data.

Data report configuration and sending period are as following:

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 0121000A0B202005200000, the firmware version is 2020.05.20

3. Data Packet:

When Report Type=0x01 is data packet.

5.3 Example for MinTime/MaxTime logic

Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange=0.1V

Note: MaxTime=MinTime. Data will only be reported according to MaxTime (MinTime) duration regardless

BatteryVoltageChange value.

Example#2 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 0.1V.

Example#3 based on MinTime = 15 Minutes, MaxTime= 1 Hour, Reportable Change i.e. BatteryVoltageChange= 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.
