1. Introduction
R718IA is a Wireless 0-5V ADC Sampling Interface. It can externally connect a device to measure ADC
voltage, and the measuring range is 0 to 5v.
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 equipment, wireless
security systems, 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.

(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.
Whenever the device sends a report, no matter resulting from data variation, button pushed or
MaxTimeinterval, another cycle of MinTime/MaxTime calculation is started.
6. 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
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 the batteries should be produced
within the last three months.
If encountering the situation of battery passivation, users can activate the battery to eliminate the battery
hysteresis.
6.1 To determine whether a battery requires activation
Connect a new ER14505 battery to a 68ohm resistor in parallel, and check the voltage of the circuit.
If the voltage is below 3.3V, it means the battery requires activation.

6.2 How to activate the battery
a. Connect a battery to a 68ohm resistor in parallel
b. Keep the connection for 6~8 minutes
c. The voltage of the circuit should be ≧3.3V
7. 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, or any liquid, might contain minerals and thus corrode electronic circuits.
If the device gets wet, please dry it completely.
• Do not use or store the device in dusty or dirty environment. It might damage its detachable parts and
electronic components.
• Do not store the device under excessive heat condition. High temperature can shorten the life of electronic
devices, destroy batteries, and deform or melt some plastic parts.
• Do not store the device in places that are too cold. 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. Rough handling of equipment can destroy internal circuit boards
and delicate structures.
• Do not clean the device with strong chemicals, detergents or strong detergents.
• Do not apply the device with paint. Smudges might block in the device and affect the operation.
• Do not throw the battery into the fire, or the battery will explode. Damaged batteries may also explode.
All of the above applies to your device, battery and accessories. If any device is not working properly, please
take it to the nearest authorized service facility for repair.
