1. Introduction R718Y is the Class A device based on the LoRaWANTM protocol of Netvox. The device detects the pressure difference and the temperature. It is compatible with the 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.

4. Set up Instruction On/Off Power on Insert batteries. (The 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 second, and the green indicator flashes 20 times. Power off Remove Batteries. 1. Remove and insert the battery; the device is at off state by default. 2.
5. Data Report When the device is powered on, it will immediately send a version package Report and the report data with the device battery voltage, the differential pressure, and the temperature. The device sends data in the default configuration before any configuration is done. Default setting: MaxTime: Max Interval = 15 min = 900s MinTime: Max Interval = 15 min = 900s BatteryChange = 0x01 (Unit: 0.1v) Different Pressure Change = 0x0A (1 Pa) (Unit: 0.1Pa) Temperature Change = 0x0A (1°C) (Unit: 0.

Notes: 1) The device only wakes up and performs data sampling according to MinTime Interval. When it is sleeping, it does not collect data. 2) The data collected is compared with the last data reported. If the data variation 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.
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.
