Introduction
LoRaWAN devices are configured using OTAA (Over-the-Air-Activation).
OTAA is the most secure way to connect a device to the LoRaWAN network. In OTAA, the device performs a Join-procedure with
the network, during which a dynamic DevAddr (device address) is assigned and security keys are negotiated with the device.
The OTAA configuration requires the following parameters to be correctly set:
•DevEUI: End-device Identifier. It is unique for every device and is set at device manufacture.
•AppEUI / JoinEUI*: Application Identifier. Used to identify the end application.
•AppKey: Application key. Used to create the session keys.
*Note: In LoRaWAN 1.1, AppEUI was renamed to JoinEUI.
For many applications Synetica can supply enLink Zone units with the AppEUI and AppKey pre-configured, so providing the LoRa
gateway has the matching values, the join process will happen automatically once the Zone unit is in wireless range and switched
on.
The DevEUI is always set at device manufacture and is unique. The device AppEUI and AppKey can easily be set via the USB
connection if required and the process is detailed later in this document.

Quick Start Guide Rev 1.4
Please see the table below for information on each menu item.
Menu Item
Description / details
Last/Minimum Reading
Shows the last CO2value read and the minimum CO2value read since the last auto calibration.
Next Auto-Cal due
Shows when the next autocalibration routine will occur
Last Auto-Cal result
Shows the value of the last auto calibration result. Used internally by the sensor.
Calibration Success
This shows the total number of successful auto calibrations since the device was powered up.
Out-of-bounds Ignored
Shows the number of times that auto calibration did not run due to the Out Of Bounds setting.
E - Enable/Disable Auto-Cal
Enables or disables the auto calibration routine.
T - Set Target CO2 Level
This is the known CO2corresponding to the minimum value the sensor has read since power-up or
last calibration. It is normally 'fresh air' or the lowest level when the building is unoccupied
overnight or at weekends. Typically this is 400 ~ 450 ppm.
K - Set to Known CO2 Level
This will re-calibrate the zero point of the sensor to a known gas concentration. The sensor should
be placed in this gas concentration and allowed to stabilise.
This command runs in the background and will take 8 to 10 seconds to complete.
As an example, fresh air is typically around 400 ~ 450 ppm.
O - Out-of-bounds check
The Out-of-bounds value is used to ignore the calibration if the minimum value the sensor has read
is not within a sensible range of the target concentration level.
So, if the target concentration level is 400, the Out-of-bounds value is ±50 and the minimum
reading is 451 (or more), the calibration routine is ignored.
I - Initial Interval
It is possible for the first auto-calibration to take place more quickly than the regular auto-
calibration events. This can be useful to stabilise the readings quickly after installation.
R - Regular Interval
This is the standard calibration interval, it is set to 8 days by default to accommodate a week long
period where the minimum sensed CO2level should have fallen to background levels.
The CO2sensor needs to be exposed to fresh, clean air periodically for the auto calibration to be successful. Most
occupied areas are unoccupied for some time during a week-long period, typically at night, or at the weekend and
therefore the auto calibration runs every 8 days by default. Background CO2levels are typically around 400-450 ppm, if
the background CO2level is known to be a different value then this can be set in the “Set Target CO2Level” parameter
If a unit is placed in an area where the CO2level may not fall below a certain level, e.g. 450ppm, during the calibration
interval then the “Out-of-bounds check” parameter can be set so that the auto calibration routine does not run. As an
example, if an area is continuously occupied for a long period and the minimum CO2reading does not fall below, say
450ppm, then it is undesirable to run the autocalibration routine based on a target of 400ppm. In this case, if the “Set
Target CO2 Level” is set to 400ppm and the “Out-of-bounds check” value is set to +/-50 ppm then the autocalibration
routine will not run unless the minimum read value falls below 451ppm in the interval.
