1. Introduction
enLink Status-VC accurately measures 0-10 Volt or 4-20mA signals generated by many analogue sensors
and instruments including temperature, pressure, speed etc.
The Voltage or Current input mode is selected by a jumper on the unit and via the USB menu.
2. Configuration
enLink 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: 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 Status with the AppEUI and AppKey pre-configured, so
providing the LoRa gateway has the matching values, the join process will happen automatically once the
Status 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.

3. Join enLink devices to the LoRaWAN network
enLink devices in wireless range and with the correct AppEUI and AppKey settings set will automatically join
the LoRaWAN network when they are first powered up.
The unique DevEUI is printed on all enLink devices and is also present in the QR code. The DevEUI can be
used to identify the device once joined to the network.
To power the device ON, remove the cover of the enLink Status by unscrewing the two screws on the cover.
Locate the power switch and using small screwdriver gently slide the power switch towards the ON position
as shown.
Switch to the ON position
Once powered ON, the enLink device will send a Join request message to the LoRaWAN network server. The
Status LED will blink RED as shown below whilst the Join process is taking place. Depending on factors such
as signal strength, RF interference etc. the join process may take several seconds to complete.
Blinking Red LED –Attempting Join
When the device has successfully joined the network the Mode LED will blink GREEN five times to show that
the join has been completed. The LED’s will then switch off to conserve the batteries.

4. Setting / changing the enLink LoRaWAN keys
For many applications, Synetica can supply enLink units with the LoRaWAN AppEUI and AppKey parameters
pre-configured to your requirements, whereby if the LoRa gateway has matching keys the join process will
happen automatically once the 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 as detailed below.
Connect a micro USB cable to the enLink unit. The device will attach to a COM port on your PC.
Using a terminal program (e.g. Tera Term https://ttssh2.osdn.jp/) connect to the COM port used by the
enLink device.
To verify which COM port is being used, check the Windows™ Device Manager (In Windows - Click the Start
button, type device manager into the search box and tap Device Manager on the menu.) Expand the Ports
(Com & LPT) menu as shown below.
In your terminal program press the Enter key. An enLink summary screen will appear as shown below. The
default password is the last four digits of the displayed DevEUI, in the screen below this is b291.
enLink logon screen
The screen below will show with the enLink Main Menu options. Enter Qto enter the Quick Start Menu.
enLink Main Menu

The Quick Start Menu contains only the parameters that normally need to be configured to setup the device
and join the LoRa network.
From the Quick Start Menu you can change the AppEUI and AppKey.
Quick Start Settings Menu
From the Quick Start Settings Menu, access the AppEUI setting by entering e. Enter the 16 character AppEUI
using numbers and letters a to f. Do not include spaces or any other characters. Pressing Swill enter the
default AppEUI which you can then edit. Rwill set a random AppEUI. Press Enter when the key is correctly
entered to return to the Quick Start Settings Menu.
AppEUI setting
From the Quick Start Settings Menu access the AppKey setting by entering k. Enter the 32 character Appkey
using numbers and letters a to f. Do not include spaces or any other characters. Pressing Swill enter the
default AppKey which you can then edit. Rwill set a random AppKey. Press Enter when the key is correctly
entered to return to the Quick Start Settings Menu.
AppKey setting
Press Xfrom the Quick Start Settings Menu to return to the enLink Main menu.

The header will show ** Reboot Required ** as shown below. The new key settings will not take effect until
the enLink device is restarted. Enter Rto reboot followed by OK. The device will restart with the entered
AppEUI and AppKey and attempt to join the LoRa network.
Reboot Required notification
Check your LoRaWAN network server to verify that the enLink device has joined successfully.
5. Setting / changing the transmit interval
Access the Transmit Interval setting by entering t from the quick start menu.
Transmit Interval settings
Select a fixed transmit interval from the menu options. 15 minutes or longer is recommended to extend
battery life.
Press Enter when the key is correctly entered to return to the Quick Start Settings Menu.

6. Setting / changing voltage / current operating mode
To change the operating mode, first set the PCB jumper on the unit.
•For 0-10 V measurements place the jumper in the VOL position.
•For 4-20 mA measurements place the jumper in the CUR position.
Voltage / Current Jumper Position
From the Main Menu access the configuration menu by entering C. This screen will display the current device
temperature, humidity and ADC readings and either the Voltage or Current, depending on the selected
operating mode.
Enter A to view the ADC menu
The Ioption allows the Voltage (0) or Current (1) mode to be set. Set the desired operating mode and ensure
that the jumper position matches.

8. Battery Installation / Replacement
enLink devices use SAFT LS14500 or EVE ER14505 AA size 3.6 Volt Lithium Thionyl Chloride (Li-SOCl2)
batteries (non-rechargeable) or direct equivalent.
No other batteries are approved for use in the device.
Lithium Thionyl Chloride batteries have very high energy capacity and must be used and handled with care
observing the guidance below.
WARNING
Risk of death or serious injury from explosion or fire.
•Keep out of sight and reach of children.
•Fire, explosion and burn hazard - do not recharge, short circuit, crush, disassemble, incinerate.
•Due to the high terminal voltage (3.6V), they are not suitable as direct replacements for other battery technologies
in the same can sizes.
•When not in use the Batteries must be stored in a non-Hazardous Area.
•Do not change batteries in an explosive gas atmosphere.
•When installing batteries, do not snag the battery terminal on the clip or the battery may be damaged. Do not apply
excessive force.
•Do not drop. Dropping the battery may cause damage. If a battery is dropped, do not install the dropped battery into
the unit. Dispose of dropped battery promptly per local regulations or per the battery manufacturer’s
recommendations.
Guidance
•Always install the batteries correctly as per instructions taking great care to observe the battery polarity.
•Ensure that the contact points are clean and conductive.
•All batteries must be the same model from the same manufacturer.
•Do not mix old and new batteries or batteries from different manufacturers.
•Do not heat or attempt to recharge the battery.
•Do not dispose of in a fire.
•Only install approved batteries: EVE ER14505 / SAFT LS14500 Lithium Thionyl Chloride AA Battery 3.6 Volt, or direct
