1. Introduction

R718IJK is a multi-sensor interface detection device for Netvox ClassA type devices based on

LoRaWAN open protocol.

R718IJK multi-sensor interface including 0-24V ADC, Dry Contact and 4-20mA, and R718IJK is

compatible with 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.

Note

Battery Life*2: Please refer to web: http://www.netvox.com.tw/electric/electric_calc.html

At this website, users can find battery life time for varier models at different configurations.

1. Actual range may vary depending on environment.

2. Battery life is determined by sensor reporting frequency and other variables.

4.Set up Instruction

4.1Power 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. 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 R718IJK 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

The device will immediately send a version packet report along with an uplink packet including

0-24VADC, Dry Contact and 4-20mA values.

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

Default value:

Maximum time: 900s (15min)

Minimum time: 900s (15min)

Reportchange:

BatteryChange ---- 0x01 (0.1V)

ADCRawValue Change ---- 0x64(100 mV) *Must more than 0x50 (80 mV)

CurrentChange ---- 0x02 (2 mA)

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:

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 change value 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

R718IJK 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. R718IJK 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.
