1. 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 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 (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 insert batteries and press 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 to check the device verification information on the gateway or consult your platform
server 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 reportchange exceeds setting value or the state changes: send a data report according
to Min Interval.
Low Voltage Warning
Low Voltage 2.4V
5. Data Report
Data report configuration and sending period are as following:
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
When the device is turned on, it will immediately send a version package and an attribute report data.
The device sends data according to the default configuration before any other configuring.
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 special customized shipments, the settings will be changed according to 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 LoRaWANApplication Command document and

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

Note:
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.

7. 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 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 excessive 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 repairing.
