  • Page 3: Introduction

    1. Introduction The R718EC is a LoRaWAN ClassA device with three-axis acceleration, temperature and is compatible with the LoRaWAN protocol. When the device moves or vibrates over the threshold value, it immediately reports the temperature, acceleration, and velocity of the X, Y, and Z axes.

    4. Set up Instruction On/Off Power on Insert batteries. (Users may need a screwdriver to open the battery cover.) Turn on Press and hold the function key for 3 seconds until the green indicator flashes once. Turn off (Reset to factory setting) Press and hold the function key for 5 seconds, and the green indicator flashes 20 times.

    (1) The device report interval will be programmed based on the default firmware which may vary. (2) The interval between two reports must be the minimum time. Please refer Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver http://cmddoc.netvoxcloud.com/cmddoc to resolve uplink data.

    When Report Type=0x01 is data packet. If the device data exceeds 11 bytes or there are shared data packets, the Report Type will have different values. b. R718EC value uses big-endian computing. c. Because of the length limitation of R718EC instruction. Therefore, R718E sends out 2 bytes and adds 0 to the data to form 4 bytes of float32.

  • Page 19: Information About Battery Passivation

    8. 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.
