1. Introduction
enLink Status-P Pulse counter accumulates pulse counts on up to three channels and can optionally monitor Change of
State on the inputs.
Common applications for the pulse counter are energy monitoring and water consumption monitoring. The unit counts
the number of pulses received from a meter and transmits the data using long range LoRaWAN wireless so the
consumption can be monitored and controlled.
The Change of State mode can be used to monitor the contact status of a switch or output, for example a door
open/closed, a piece of equipment on/off or an alarm condition in alarm/normal.
The operational mode of pulse counting or pulse counting plus Change of State monitoring is selected 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 5e00.

Meter pulse output debounce
Depending on the cable length and its electrical characteristics, a meter pulse signal can “ring” or
“bounce” causing false counting. To address this, most energy meters adhere to the S0 standard as
defined in EN62053-31.
S0 Standard Pulse Timing
The S0 standard stipulates that a meter pulse output should remain in the ON-state for at least
30mS and in the OFF-state for at least 30mS and with a rise/fall time of less than 5mS. enLink
Status-P samples the inputs many times on each transition to ensure that the signal remains
constant for the required time and therefore prevents false counting.
The debounce time can be independently set for each channel for periods of between 10mS to
250mS, however this should be used with caution as it can cause mis-counts. Leave this setting at
30mS to match the S0 standard requirements.

7. Operating Mode
The unit can be used as a Pulse Counter, or as a Pulse Counter and Change of State monitor. The
operational mode is set via the Pulse Counter Options menu.
With the Transmit on Change of State disabled the unit operates as a standard pulse counter.
With the Transmit on Change of State enabled the unit operates as a standard pulse counter and
also transmits a LoRaWAN message when the state of the input changes from closed to open or
open to closed.
The message transmitted sends the current status of all three inputs (open or closed) plus the
“trigger status”which indicates the reason for the transmission, e.g., input changed from Closed to
Open.
To enable or disable the Transmit on Change of State, enter Cand confirm eto enable or dto
disable.
When Transmit on Change of State is enabled you must also enable Adaptive Transmit Intervals as
shown below.
Enter Qto enter the Quick Start Menu.
Quick Start Settings Menu
Access the Transmit Interval setting by entering t.

Transmit Interval settings
To select a fixed transmit interval select the required interval from the menu options.
To select Adaptive Transmit Interval select the Aoption and then change the settings for the
Adaptive Min interval and Adaptive Max interval as required.
With adaptive transmit interval set, when a Change of State occurs a wireless message is sent
immediately, however messages will not be sent more frequently than the Adaptive Min interval.
The Adaptive Max interval acts like a heartbeat, so if no Change of State occurs then a message is
sent at the Adaptive Max interval.
