Introduction

R311DA is a wireless long-distance ball-type vibration device that is a Class A device based on the LoRaWANTM protocol of NETVOX. It 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 extends the communication distance. It can be widely used in any use case that requires long-distance and low-data wireless communications. Examples, automatic meter reading, building automation equipment, wireless security systems, and 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.

Set up Instruction

On/Off

Power on| Insert batteries (the user may need a screwdriver to open)
Insert 2 x 3V CR2450 button batteries into the battery slot in the correct direction and close the back cover.
Note: Require 2 button batteries to supply power at the same time.
---|---
Turn on| Press any function key till the green and red indicator flashes once.
Turn off (Restore to factory setting)| Press and hold two function keys for 5 seconds and the green indicator flashes 20 times.
Power off| Remove Batteries.
Note:| 1. Remove and reinsert the battery: the device will remember the previous on/off status by default.
2. After inserting batteries and pressing the button at the same time, the device will be in engineering testing mode.
3. On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor inductance and other energy storage components.
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 checking the device verification information on the gateway or consulting your platform service 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 report change exceeds the setting value or the state changes: send a data report according to Min Interval.
---|---

Low Voltage Warning

Low Voltage	2.4V

Data Report

When the device is turned on, it will immediately send a version package and attribute report data. The device sends data according to the default configuration before any other configuration.

Default setting:

Maximum time: 3600s
Minimum time: 3600s (Default: Every Min Interval will detect the state of the dry contact one time) BatteryChange: 0x01 (0.1V)
(If there are specially customized shipments, the settings will be changed according to the customer’s requirement.)

R311DA trigger:

** When the device senses vibration and the ball is shaken, an alarm message will be reported. The shaking alarm bit is “1”.
The static and non-shaking alarm bit is “0”.
Restore Function:
There are two ways for the ball to trigger an alarm.
One is not to report the recovery status after sending the alarm. (default)
** The other is to report the recovery status after the device stops vibrating for 5 seconds after sending the alarm. The two ways can be executed before shipment or by LoRaWan command configuration

Note:
The interval between two reports must be the MinTime.
The reported data is decoded by the Netvox LoRaWAN Application Command document and http://loraresolver.netvoxcloud.com:8888/page/index

Data report configuration and sending period are as follows:

Min Interval (Unit: second)| Max Interval (Unit: second)| Reportable Change| Current Change≥ Reportable Change| Current Change＜
Reportable Change
---|---|---|---|---
Any number between
1~65535| Any number between
1~65535| Can not be 0.| Report per Min Interval| Report per Max Interval

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 Maxime (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.

Note:

The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data.
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 the MinTime interval. If the data variation is not greater than the last data reported, the device reports according to the Maxime interval.
3)We do not recommend setting 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.
Whenever the device sends a report, no matter resulting from data variation, button pushed, or Maxime interval, another cycle of MinTime / Maxime calculation is started.

Installation

(1) The device does not have a waterproof function. After the configuration of joining the network is completed, please place it indoors.
(2) The dust at the installation location should be wiped clean before pasting the device.
(3) The battery installation method is as the figure below. (the battery with the “+” side facing up)

Important Maintenance Instruction

Kindly pay attention to the following in order to achieve the best maintenance of the product:

Keep the equipment dry. Rain, moisture, and various liquids or water may contain minerals that can corrode electronic circuits. In case the device is wet, please dry it completely.
Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components.
Do not store in an excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts.
Do not store in an excessively cold place. Otherwise, when the temperature rises to normal temperature, moisture will form inside which will destroy the board.
Do not throw, knock or shake the device. Treating equipment roughly can destroy internal circuit boards and delicate structures.
Do not wash with strong chemicals, detergents, or strong detergents.
Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation.
Do not throw the battery into the fire to prevent the battery from exploding. Damaged batteries may also explode.

All the above suggestions apply equally to your device, batteries, and accessories.
If any device is not operating properly.
Please take it to the nearest authorized service facility for repair.
