and waiting for the end message.
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 15 and 65535 minutes (default: 30 minutes).

e n g i n k o . s u p p o r t . c e n t e r - http://www.enginko.com/support/
Period interval can be set with LoRaWEB or with downlink command.
4.2 Thresholds
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

the latest measure.
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.

If not handled in the right way can generate unnecessary traffic on the network.
Please check chapter 2.1 DATA FRAME FORMAT.
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.
5. Diagnostic
Press Check to see the analog values.
6 LoRaWAN network
The sensor is compliant with LoRaWAN® specification 1.0.2, regional 1.0.2b.

6.1 Activation
The device supports the following activations on a LoRaWAN® network:
NONE: sensor not activated1.
OTAA: the JoinEUI and the AppKey not setted, must be written to the device;2.
OTAA MCF88: Over the air activation, fixed keys: JoinEUI = 904e915000000002, AppKey on3.
request;
OTAA ENGINKO: Over the air activation, fixed keys: JoinEUI = 904e915000000002, AppKey on4.
request;
ABP: requires writing to the device of NwkSkey, AppSkey, DevAddr.5.

e n g i n k o . s u p p o r t . c e n t e r - http://www.enginko.com/support/
The device exits factory activated with NONE mode. On request devices can be shipped aleady
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: 2022/02/16 09:15 manual_mcf-lw06424 http://www.enginko.com/support/doku.php?id=manual_mcf-lw06424
http://www.enginko.com/support/ Printed on 2022/02/16 09:16
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.

e n g i n k o . s u p p o r t . c e n t e r - http://www.enginko.com/support/
8.1 Multi devices configuration
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.
