2.2 Installation

The installation has to be done by a qualified electrician.

The device is intended as subassembly (component).

It is responsibility of the assembler of equipment incorporating to ensure that the overall equipment is safe.

The MCF-LW13MIO must be mounted in vertical position.

2.2.1 Antenna

The magnetic antenna must be positioned on a metal body. It should preferably be vertical and at least 30 cm away from other metal bodies. The installation must take place in a place where the LoRaWAN® signal coverage is good (SF=7 optimal, SF=12 weak).

2.3 Power supply

and waiting for the end message.

3 I/O

As default, the device sends a message every time an input or an output changes.

A downlink with new output status forces the device to send back an unplink with the new status. If the output status is the same of current one, the sensor will not send back any message.

Downlink examples (hex):

turn ON the output 1: 0400 0100 0000 0000 0000
turn off the output 1: 0400 0000 0000 0100 0000
receive the current status: 0400 0000 0000 0000 0000

Is possible to set a period (in minutes) to receive a recurrent periodic message with the I/O status.

Maximum switching voltage 250Vac~
Minimum switching load mW 500mW (10V/5mA)

If driving an inductive load in AC, a Snubber must be provided in parallel to the contacts formed by a RC resistance network = 100Ohm 2w in series with a 100nF 400Volt polyester capacitor. In the case of a DC-controlled load, an anti-parallel diode must be placed on the load (ex. 1N4007). Each line must be protected with a suitable fuse (FUSE).

The output has pulse capability (minimum pulse duration is 100ms, maximum around 100 minutes), so, instead to send two different commands (one to turn on and one to turn off the ouput), is possible to send a duration command.

As application example, to safely turn on an output, send a ON-pulse command for a defined time (for example, for the maximum allowed interval), and before the expiring time, another ON-pulse command (making a kind of watchdog) if the output still needs to be ON, or a simply OFF command if you want to turn it off.

3.2.1 Time schedule

It is possible to program the device with a weekly calendar, based on day of the week and time, to turn ON and OFF the output at a defined time:

and generate and XLS file that can be downloaded by downlinks:

4 LoRaWAN® network

The sensor is compliant with LoRaWAN® specification 1.0.2, regional 1.0.2b.

4.1 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 = 904e915000000003, AppKey on request;
  4. OTAA ENGINKO: Over the air activation, fixed keys: JoinEUI = 904e915000000003, AppKey on request;
  5. ABP: requires writing to the device of NwkSkey, AppSkey, DevAddr.

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.

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).

LoRa Band:
select the right LoRaWAN ® band settings accodingly to country requirements.

5 Configuration

5.1 I/O settings

Status of the output at power on:
select the status of OUTPUT 1 at power-on (default: off).

I/O reading period [min]:
if different from 0, this is the interval (in minutes) between one I/O messages status and the next one. Value can be between 1 and 255 minutes (default: 0 minutes - disabled). Period interval can be set with LoRaWEB or with downlink command.

Number of counter inputs:
Number of inputs used as pulses counters. Value = 1 means that input 1 is a pulses counter, value = 3 means the fist 3 inputs are pulses counter . (default: 0).

Counters reading period [min]:
if counter enabled, this is the interval (in minutes) between one measure and the next one. The sensor sends one measures for every transmission. Value can be between 1 and 255 minutes (default: 0 minutes).
Period interval can be set with LoRaWEB or with downlink command.

5.2 Other settings

Led working:
enable/disable status led (default: enabled).

Time Sync uplink:
enable/disable time synchronization request (default: enabled).

Normally sensor asks for a time sync at every power on (uplink starting with 01) or, if enabled, once a week.

Please check chapter 2.1 DATA FRAME FORMAT.

Confirmed uplinks:
set for confirmed uplinks (default: confirmed uplink).

Single join/day:
set for to allow only one join per day (default: multiple join allowed).

change USB port function (default: Standard).

set to change DST (default: none).

5.3 Diagnostic

6 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:

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).

7 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.

7.1 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.
