Do you have a question about the Enginko MCF-LW06DAVK and is the answer not in the manual?

The MCF-LW06DAVK/DAVPK is a LoRaWAN® communication system kit designed to be connected to Davis Vantage Pro2 Weather Station. This manual provides comprehensive information on its operation, technical specifications, usage, and maintenance.

Function Description

The MCF-LW06DAVK/DAVPK serves as an interface between a Davis Vantage Pro2 Weather Station and a LoRaWAN® network. It enables the transmission of weather data collected by the Vantage Pro2 to a LoRaWAN® gateway, allowing for remote monitoring and data analysis. The device is designed to be robust and reliable, suitable for various environmental conditions. It supports both LoRaWAN® activation methods: OTAA (Over-the-Air Activation) and ABP (Activation by Personalization).

The system includes a sensor suite (Davis Vantage Pro2 Groweather sensor suite 6820CM or ISS Davis Vantage Pro2 sensor suite 6820CM), a cabled weather Envoy (6316CEU or 6316CEU), and a WeatherLink® Serial-Port Data Logger (6510SER or 6510SER). It also includes a solar box (6612 or 6612) and an optional UV sensor (6490 or 6490). The kit is designed to work with these Davis components, ensuring seamless integration and data collection.

LoRaWAN® Parameters:

Network Key: User-configurable
App Key: User-configurable
Device Address: User-configurable

Network settings: Any, Objenious, Public Network, Private Network
Network type: Private (0x12) instead of Public (0x34) for LoRa syncword. The NS must be set accordingly.
Band: Select the right LoRaWAN® band settings according to country requirements.

Firmware Update: The device supports firmware updates via a USB port, allowing for improvements and bug fixes. The update process involves running an executable file on a PC and connecting the device via USB.

Usage Features

Installation: The installation process involves several steps to connect the MCF-LW06DAVK/DAVPK to the Davis Vantage Pro2 Weather Station.

Remove the 6316CEU by sliding down-up and pull.
Insert provided 4xAA size batteries on the 6316CEU.
Connect the "console" cable "A" coming from the 6820CM, by entering the box using the gasket on the bottom side's hole.
Fasten the 6316CEU to the box.
Connect the red wire terminal "B" to the positive terminal of the battery "C".
Connect the white connector to the LoRaWAN® interface "D".

The device is mounted on the pole using fasteners. The antenna connector to the MCF-LW06DAV device (Davis station to LoRaWAN™ interface) is connected by entering the box using the gasket on the bottom side's hole. The PM sensor, if present, is mounted on the pole at the back of the DW-6612 solar panel box, following the enclosed instruction.

Configuration: The device is configured using a web-based tool, LoRaWEB (iot.mcf88.cloud/LoRaWeb), to set up LoRaWAN® credentials and other preferences. This tool is only available for Windows®. Before connecting the device for the first time, users need to install LoRaBridge applications and drivers.

Setup Parameters:

Period: The interval (in minutes) between one measure and the next one. The sensor sends one measure for every transmission. Value can be between 15 and 65535 minutes (default: 30 minutes). Period interval can be set with App or with downlink command.
Altitude compensation: The sensor is not installed at sea level, the reading of barometric pressures at other elevations must be compensated. The right altitude value with LoRaWEB can be set. Value can be from -300 to 3000 meters. Altitude can also be set with downlink command.
DST: Set to change DST (default: none).
Time sync uplink: Set to disable time synchronization request (default: enabled). Normally sensor asks for a time sync at every power on (uplink starting with 01) or once a week. If no or wrong reply received it will retry after 1 hour. If not handled in the right way can cause a unnecessary battery consumption (battery life < 2 years).
Confirmed Uplinks: Set for unconfirmed uplinks (default: confirmed uplink).
Single join/day: Set for to allow only one join per day (default: multiple join allowed).
LED working: Set OFF to turn off the diagnostic led.
USB: Internal use.

Diagnostic: The LoRaWAN® interface and the Davis envoy can be checked for correct communication using the "Check" button in the diagnostic section of the configuration tool. The status will show "OK" if communication is successful.

LoRaWAN® Network Configuration:

Activation: Users can choose between NONE (sensor not activated), OTAA, OTAA MCF88, OTAA ENGINKO, and ABP. For OTAA, the JoinEUI and AppKey must be set. For ABP, NwkSKey, AppSKey, and DevAddr are required.
Network Settings: Options include Any, Objenious, Public Network, and Private Network.
Passwords: The device is protected by passwords to avoid unauthorized persons to read data or modify parameters. Default passwords are equal to 0. Allowed values range from 0 to 999999999 (only numbers). Passwords can be changed via LoRaWEB. To bring back the sensor to factory default and reset the passwords, a reset code must be requested to enginko (please provide the DevEUI of the sensor when you ask for that code).

Configuration File: LoRaWEB allows users to configure the device using an XML file, instead of manually adjusting parameters. This is useful for multiple devices configuration. A "Save" button allows saving the current configuration of the sensor. An additional XLS file can be used to load different LoRa configuration parameters (Activation Type, AppKey, AppEUI, NetKey, DevAddress, Band, Private option) for each sensor, based on DevEUI. If both files are enabled, the DevEUI of the device matches one of the DevEUIS in the XLS file, LoRa parameters will be set from this one.

Payload: The document provides details on payload descriptions, uplinks and downlinks format and available commands. This includes a DATA FRAME FORMAT for understanding the data structure.

Maintenance Features

General Maintenance:

Disposal Information: The barred symbol of the rubbish bin on the equipment indicates that, at the end of its useful life, the product must be collected separately from other waste. For additional information and how to carry out disposal, please contact the certified disposal service providers.
