1. Introduction

The R718LB2 is a long-range (communication distance) Wireless 2-Gang Hall Type Open/Close

Detection Sensor for Netvox Class A type devices based on the LoRaWAN open protocol, and is

compatible with the LoRaWAN protocol.

LoRa Wireless Technology:

LoRa is a wireless communication technology famous for its long-distance transmission and low

power consumption. Compared with other communication methods, LoRa spread spectrum

modulation technique greatly extend the communication distance. It can be widely used in any use

case that requires long-distance and low-data wireless communications. For example, automatic

meter reading, building automation equipment, wireless security systems, industrial monitoring. It

has features like small size, low power consumption, long transmission distance, strong

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 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.

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 to join.

The green indicator stays on for 5 seconds: success

The green indicator remains off: fail

Had joined the network

(not at factory setting)

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

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

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

sensor status and battery voltage.

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

Default setting:

MaxTime: Max Interval = 60 min = 3600s

MinTime: Min Interval = 60 min = 3600s

BatteryChange: 0x01 (0.1V)

Hall sensor status:

When the magnet closes to the Hall sensor, it will report the status “0”

(The distance between the magnet and the Hall sensor is less than 3cm)

When the magnet removes the Hall sensor, it will report the status “1”

(The distance between the magnet and the Hall sensor is greater than 3 cm)

Note:

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

The interval between two reports must be the minimum time.

Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command

Resolver http://loraresolver.netvoxcloud.com:8888/page/index to resolve uplink data.

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.

Low Voltage Warning

Low Voltage 3.2V

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.
