Introduction
R311K is a long-distance tilt detection device that is a Class A device based
on the LoRaWAN open protocol of Netvox and is compatible with the LoRaWAN
protocol. The device is a title detection sensor. When the device is tilted
greater than or equal to 45 degrees in any direction, it will send a tipping
signal.
LoRa Wireless Technology:
Lora is a wireless communication technology dedicated to long-distance and low
power consumption. Compared with other communication methods, the LoRa spread
spectrum modulation method greatly increases to expand the communication
distance. Widely used in long-distance, low-data wireless communications.
Examples, automatic meter reading, building automation equipment, wireless
security systems, and 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.

Set up Instruction
On/Off
Pmoer 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 and hold the function key till the green and red indicator
flashes once.
Turn off
(Restore to original setting)| Press simultaneously and hold two buttons for 5
seconds, and then the green indicator flashes 20 times and the device will
turn off automatically.
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 join 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 restored to the original 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
Fail to join the network| Suggest checking the device verification information
on the gateway or consult your platform sere es provider
Function Key
Press and hold for 5 seconds| Restore to the original 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 turned on and joins in the network| Sleeping period: Min
Interval.
When the report change exceeds the default or the state of the device changes:
send a data report according to Min Interval.
---|---
Low Voltage Warning
Low Voltage ………………. 2.4V
Data Report
After power on, the device will immediately send a version packet report and
an attributes report.
The device sends data according to the default configuration before any other
configuration.
Default setting:
Report MaxTime：Max Interval —-3600s
Report MinTime ：Min Interval —-3600s (Default: Every Min Interval will detect
the state of the dry contact one time)
BatteryVoltageChange —- 0x01(0.1V)
Triggering the tilt detection:
The device adopts 45° tilt detection around the entire circumference. The
initial state of the device is vertical placement.
When the tilt angle (any direction) changes more than 45° (45°~180°), a
tipping alarm will be issued immediately.
Device Tilt: 1, Device Recovery: 0
Note:
- The cycle of the device sending the data report is according to the default.
- The interval between two reports must be the MinTime.
- R311K defaults Max Interval = 60min, Min Interval = 60min
(If there are specially customized shipments, the settings will be changed
according to the customer’s requirement.)
The device reported data parsing please refer to

Data report configuration and sending period are as follows：
Min Interval

(Unit: second)| Reportable Change| Current Change >
Reportable Change| Current Change < Reportable Change
---|---|---|---|---
Any number between
1-65535| Any number between

(1) Configure R311K device parameter
MinTime = 1min、MaxTime = 1min、BatteryChange = 0.1v
Downlink ： 019E003C003C0100000000
Device return：
819E000000000000000000 (configuration success)
819E010000000000000000 (configuration failure)
(2) Read R311K device parameter
Downlink ： 029E000000000000000000
Device return：
829E003C003C0100000000 (device current parameter)
Example#1 based on MinTime = 1 Hour, MaxTime= 1 Hour, Reportable Change
i.e. BatteryVoltageChange=0.1V Note: MaxTime=MinTime. Data will only be
report according to MaxTime (MinTime) duration regardless BtteryVoltageChange
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.
Notes:
- The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data.
- The collected data is compared with the last reported data. If the variation of the data is greater than the value of ReportableChange, the device will report according to the MinTime interval. If the data variation is not greater than the last reported data, the device will report according to the Maxime interval.
- We do not recommend setting the MinTime Interval value too low. If the MinTime Interval is too low, the device will wake up frequently and the battery will be drained soon.
- When the device sends a report, no matter the data changes, the button is pushed or the Maxime interval comes, another cycle of MinTime / Maxime calculation starts.
Installation
- The device does not have a waterproof function. After the configuration of joining the network is completed, please place it indoors.
- The dust at the installation location should be wiped clean before pasting the device.
- The battery installation method is as the figure below. (the battery with the “+” side facing up)
Note : The user may need a screwdriver to open the cover.
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.
