1. Introduction

R313WA is a ClassA wireless 2-gang seat occupancy device based on standard LoRaWAN protocol. The R313WA will report

to the gateway whenever one of the 2-gang seat occupancy sensor detects external pressure. It will also report to the gateway

when the external pressure is gone.

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 two sections of 3V CR2450 button batteries and close the battery cover.

Note: users may need a flat blade screwdriver to open the battery cover.

Turn on

Press any function key until the green and red indicator flashes once.

Turn off

(Reset to factory setting)

Press and hold both function keys for 5 seconds until the green indicator flashes for 20 times.

Power off

Remove Batteries.

Note:

1. The device would memorize the previous on/off state by default even when user removes

and inserts the battery.

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

inductance and other energy storage components.

3. The device will be in engineer testing mode when user presses any function key and inserts

batteries at the same time.

Network Joining

Never joined the network

Turn on the device to search the network.

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.

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)

Note:

(1) Please remove batteries if the device is not used to save power.

(2) Please check the device verification information on the gateway with your platform server

provider.

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

Sleeping Mode

The device is on and in the

network

Sleeping period: Min Interval.

When the reportchange exceeds setting value or the state changes, the device would send a

data report according to Min Interval.

The device is on but not in

the network

Note:

(1) Please remove batteries if the device is not used to save power.

(2) Please check the device verification information on the gateway with your platform server

provider.

5. Data Report

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

2. The transmission frequency of sending version package is once every 24 hours.

3. Data will be reported once per hour by default setting.

Default setting:

Maximum time: 3600s

Minimum time: 3600s

Battery: 0x01 (0.1V)

Disabletime:0x001E (30s)

Detectiontime:0x0078 (120s)

*The setting of 2-gang is same.

* DisableTime must ≧5s , Detection Time must ≧DisableTime .

4. Pressure detecting:

R313WA is equipped with two-gang seat occupancy sensor.

When the seat occupancy sensor detects changes with the pressure status R313WA will report.

When the seat is taken, report 1.

When the seat is not taken, report 0.

Note:

The reported data is decoded by the Netvox LoRaWAN Application Command document and Netvox LoRa Command

Resolver http://www.netvox.com.cn:8888/cmddoc

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 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.
