4. Setup
4.1 Period
Period is the interval (in minutes) between one measure and the next one. The sensor sends one measures for every transmission. Value can be between 5 and 65535 minutes (default: 10 minutes).

Period interval can be set with LoRaWEB or with downlink command.
4.2 Thresholds
MCF-LW06424 Operating Manual
On the MCF-LW06424 is possible to set 4 thresholds for each channel:
Th+ = Threshold High Rising Th- = Threshold High Falling Tl+ = Threshold Low Rising Tl- = Threshold Low Falling
When target values are rising and exceed the positive thesholds, the device sends an uplink with the
e n g i n k o . s u p p o r t . c e n t e r - https://www.enginko.com/support/

the latest measure.
manual_mcf-lw06424 https://www.enginko.com/support/doku.php?id=manual_mcf-lw06424
When values are falling below the negative thresholds, the device sends a new uplink with the latest measure.
Thresholds can be enabled, disabled and changed va USB with LoRaWEB or with downlinks:
4.3 Other settings
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 week.

6.1 Activation
The device supports the following activations on a LoRaWAN® network:
1. NONE: sensor not activated 2. OTAA: the JoinEUI and the AppKey not setted, must be written to the device; 3. OTAA MCF88: Over the air activation, fixed keys: JoinEUI = 904e915000000002, AppKey on
request; 4. OTAA ENGINKO: Over the air activation, fixed keys: JoinEUI = 904e915000000002, AppKey on
request; 5. ABP: requires writing to the device of NwkSkey, AppSkey, DevAddr.

MCF-LW06424 Operating Manual
The device exits factory activated with NONE mode. On request devices can be shipped already activated. Note: in OTAA AppKey is write only, in reading the field will always be empty, even if set.
6.2 Other settings
Network settings: please keep "Any" settings. Change it only if Objenious network is used (default_ any). Network type: LoRa syncword can be setted as "private"(0x12) instead "public" (0x34), but the NS must be setted accordingly (default: public). Band: select the right LoRaWAN ® band settings accodingly to country requirements.
7 Passwords
The device can be protected by passwords, to avoid unauthorized persons to read data or modify parameters. As default passwords are equal to 0. Allowed values range from 0 to 999999999 (only numbers). To change the passwords, set the new values with LoRaWEB:

Last update: 2023/05/29 07:33
manual_mcf-lw06424 https://www.enginko.com/support/doku.php?id=manual_mcf-lw06424
Once the passwords are setted, to gain access from LoRaWEB to the sensor, set the right values before reading from the device:
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).
8 General configuration file
WIth LoRaWEB is possible to configure the device using an XML file, instead to manually adjust the parameters (for details about the file format please ask to enginko). This is very useful especially in case of multiple devices configuration. With "Save" button an XML file with the actual configuration of the sensor will be generated. This is useful to store or clone the configuration, or to send it to enginko's support if needed.

8.1 Multi devices configuration
MCF-LW06424 Operating Manual
WIth LoRaWEB is possible to configure many devices in an easy way.
For multi-configuration is needed at least one XML file with the parameters to set.
Settings on this file will be applied to all the sensors.
With an additional XLS file is possible to load different LoRa configuration parameters (Activation Type, AppKey, AppEUI, NetKey, DevAddress, Band, Private option) for each sensor, based on DevEUI.
XLS is prevailing on the XML, so if both files are enabled, if the DevEUI of the device matches one of the DevEUIs in the XLS file, LoRa parameters will be setted from this one.
These configuration can be done in the in the Settings:
Use of the general configuration by file; Use of the specific configuration by file.
For details on files format please ask to enginko.
