Introduction

R718IB is an ADC sampling interface detection device for NetVu Class A type devices based on Lora WAN open protocol.
The device is suitable for detecting 0V to 10V, and R718IB is compatible with Lora WAN 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.
Lora WAN:
Lora WAN uses Lora technology to define end-to-end standard specifications to ensure interoperability between devices and gateways from different manufacturers.

Tips

1. Battery Voltage:
   The voltage value is bit 0 ~ bit 6, bit 7=0 is normal voltage, and bit 7=1 is low voltage.
   Battery=0xA0, binary=1010 0000, if bit 7= 1, it means low voltage.
   The actual voltage is 0010 0000 = 0x20 = 32, 32*0.1v =3.2v

2. Version Packet:
   When Report Type=0x00 is the version packet, such as 012A000A0B202005200000, the firmware version is 2020.05.20

3. Data Packet:
   When Report Type=0x01 is data packet.

1.  Configure the device parameter Min Time = 1min, Maxime = 1min, Battery Change = 0.1V, AD Craw Value Change= 100mV
   Downlink: 012A003C003C0100640000
   Device Return:
   812A000000000000000000 (configuration success)
   812A010000000000000000 (configuration failure)

2. Read the device parameter

   Device Return:
   822A003C003C0100640000 (device current parameter)

5.3 Example for Min Time/Max Time logic
Example#1 based on Min Time = 1 Hour, Max Time= 1 Hour, Reportable Change i.e. Battery Voltage Change=0.1V

Note: Max Time=Min Time. Data will only be report according to Max Time (Min Time) duration regardless Battery Voltage Change value.
Example#2 based on Min Time = 15 Minutes, Max Time= 1 Hour, Reportable Change i.e. Battery Voltage Change= 0.1V

Example#3 based on Min Time = 15 Minutes, Max Time= 1 Hour, Reportable Change i.e. Battery Voltage Change= 0.1V

Notes:

1. The device only wakes up and performs data sampling according to Min Time Interval. When it is on sleeping mode, it does not collect data.
2. The data collected is compared with the last data reported. If the data variation is greater than the Reportable Change value, the device reports according to Min Time interval. If the data variation is not greater than the last data reported, the device reports according to Max Time interval.
3. We do not recommend to set the Min Time Interval value too low. If the Min Time 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 Max Time interval, another cycle of Min Time/Max Time calculation is started.

Installation

1. Wireless ADC Sampling Interface (R718IB) has the built-in magnet (as the figure below). When installed, it can be attached to the surface of an object with iron which is convenient and quick. To make the installation more secure, use screws (purchased) to
   secure the unit to a wall or other surface (as the figure below , the installation diagram of R718A is taken as an example because the main body has the same appearance).
   Note:
   Do not install the device in a metal shielded box or in an environment with other electrical equipment around it to avoid affecting the wireless transmission of the device.

2. Connect the sampling line of the ADC sampling interface sensor to the transmitter according to the wiring method shown in figure. There are two connection modes, 2-wire and 3-wire.

3. When the ADC sampling interface sensor detects the current voltage according to the configured time or by pressing the button, it sends the data immediately

It can also be applied to the following scenarios:

• Pressure transmitter
• Differential pressure transmitter
• Level transmitter

Information about Battery Passivation

Many of NetVu 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 reaction 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:
7.1 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.
7.2 How to activate the battery
a. Connect a battery to a resistor in parallel
b. Keep the connection for 5~8 minutes
c. 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.

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 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.
