Introduction

R718UBB all-in-one series is a ClassA type testing device based on the LoRaWAN open protocol of Netvox, which can support multiple combinations of temperature and humidity, CO2, vibration, atmospheric pressure, and illumination sensors, and is compatible with LoRaWAN protocol.

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 devices, wireless security systems, and industrial monitoring. The 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.

The specific model of R718UBB all-in-one is shown in the following table: UBB represents the basic function of battery power CO2

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 the green indicator flashes 20 times.
Power off| Remove Batteries.

Note:

| 1.     Remove and insert the battery; the device is at off state by default. Turn on the device to use it again.

2.     On/off interval is suggested to be about 10 seconds to avoid the interference of capacitor inductance and other energy storage components.

3.     In the first 5 seconds 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 the factory setting)

| Turn on the device to search for 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 consulting your platform

server provider.

Function Key

Press and hold for 5 seconds

| Restore to factory setting / Turn off

The green indicator rapidly flashes 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: the green indicator remains off

Sleeping Mode

The device is on and in the network

| Sleeping period: Max Interval.

When the report change exceeds the setting value or the state changes: send a data report according to Max Interval.

Low Voltage Warning

Low Voltage

| 3.2V(after reporting low voltage, the device may still work, but the CO2 data will be inaccurate.

Please replace the battery in time)

Data Report

• When the device is powered on, it will immediately send a version package report and then report the device data.

Default setting

• Min interval = 10s (subject to factory setting)
• Max interval = 15min (subject to factory setting)
• R718UBB,R718UBB1,R718UBB12 reportcount=1
• R718UBB123,R718UBB23,R718UBB25,R718UBB125,R718UBB235,R718UBB1235 reportcount=2

Data detection

When the device is in a network state, the light flashes once after pressing the key and then reads the data. When the time to return the corresponding data or configure is up, it will also detect and return the corresponding data information. (Note: The interval between multiple data packets is meantime)

Note

1. Before any configuration, the device sends data according to the default configuration.
2. Do not send any configuration before turning on the device.
3. CO2 data will be unstable due to transportation relations, long storage time, and other factors.

• If the CO2 value which customers test is inconsistent, or there is a large discrepancy of the primary standard, it can be recalibrated. For specific calibration methods, please refer to command 0x03 CalibrateType.
• Refer to Netvox LoRaWan Application Command documents and for data analysis reported by the device http://www.netvox.com.cn:8888/page/index Instruction parsing

Information about Battery Passivation

• Many of Netvox devices are powered by 3.6V ER14505 Li-SOCl2 (lithium-thionyl chloride) batteries that offer many advantages including low self-discharge rate and high energy density.
• However, primary lithium batteries like Li-SOCl2 batteries will form a passivation layer as a reaction between the lithium anode and thionyl chloride if they are in storage for a long time or if the storage temperature is too high. This lithium chloride layer prevents rapid self-discharge caused by continuous reactions between lithium and thionyl chloride, but battery passivation may also lead to voltage delay when the batteries are put into operation, and our devices may not work correctly in this situation.
• As a result, please make sure to source batteries from reliable vendors, and it is suggested that if the storage period is more than one month from the date of battery production, all the batteries should be activated.
• If encountering the situation of battery passivation, users can activate the battery to eliminate the battery hysteresis.

ER14505 Battery Passivation

To determine whether a battery requires activation

• Connect a new ER14505 battery to a resistor in parallel, and check the voltage of the circuit.
• If the voltage is below 3.3V, it means the battery requires activation.

How to activate the battery

• Connect a battery to a resistor in parallel
• Keep the connection for 5~8 minutes
• The voltage of the circuit should be ≧3.3, indicating successful activation.

Note
If you buy batteries from other than the above four manufacturers, then the battery activation time, activation current, and required load resistance shall be mainly subject to the announcement of each manufacturer.

Precautions for Outdoor Installation

• According to Enclosure Protection Class

• This standard is equivalent to IEC 60529:2001 Degrees of Protection Provided by Enclosures

• The test method for IP65 waterproof grade is:
  spray the device in all directions under 12.5L/min water flow for 3min, and the internal electronic function is normal.

• The test method for IP67 waterproof grade is:
  the device is immersed in 1m deep water for 30min, and the internal electronic function is normal.

• IP65 is dust-proof and prevents damage caused by water from nozzles in all directions from invading electrical appliances. It can be used in general indoor environments and sheltered outdoor environments.

• It is not suitable for use in environments with high water pressure, high temperature, and high humidity, such as long-time direct sunlight outdoors and possible direct exposure to rainstorms. If it is really necessary to install in harsh environments, it is recommended to add sunscreen and rainproof shields when installing.

Important Maintenance Instruction

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

• Keep the device 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 excessively cold places. 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 devices 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 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.
