1 DESCRIPTION AND OPERATION
Vega SI-12 pulse counter is designed for counting of pulses incoming to 4 independent
inputs, further accumulating and transmitting of this information via the LoRaWAN protocol to
the gateway through wireless communication within 860-1000 MHz frequency band.
In addition, Vega SI-12 can be used as a security device - all inputs can be configured as
security inputs.
The counter has two open-collector digital outputs and can be used as a control device.
The pulse counter can be used for any utilities’ meters and industrial equipment with
pulse output of herkon type or open-drain type.
Equipment with NAMUR pulse output is not supported
De-bouncing logics with 5 msec time constant is integrated in the pulse counter. The
pulse counting is carried out for frequencies up to 200 Hz.
The counter is powered by a 3400 mAh built-in battery with service life up to 10 years,
provided data transmitted once a day. The counter can be powered by the 5V external power
supply.
The counter is configured via USB with special software.
The label on the board contains the information for registering of the device in the
LoRaWAN network:
DevEUI,
DevAddr,

Equipment with NAMUR pulse output is not supported
Any input can be configured for work in the "Security" mode with “Vega LoRaWAN
Configurator” software when connected to the counter via USB. In this case, the device does
not count pulses at the "Security" input, but only monitors its closure. Should the "Security"
input close, the device is activated and sends an alarm message to the network.

INITIAL STARTUP
Vega SI-12 pulse counter is constantly on, but can operate in a special "Storage" mode,
designed for storage and transportation. The device does not regularly transmit data to the
network in this mode. Before use, switch the counter from the «Storage» mode.
Vega SI-12 supports two activation methods in the LoRaWAN network - ABP and OTAA.
Select one of the methods using “Vega LoRaWAN Configurator” application (See chapter
“Alignment”).
1. ABP. After pressing the start button, the device immediately starts working in the
"Active" mode.
2. OTAA. After pressing the start button, the device makes three attempts to connect to
the network within the set frequency band. After the activation in the LoRaWAN network is
confirmed, the device sends a signal (LED flashing for 3 seconds) and switches to the "Active"
mode. If all attempts fail, the counter switches to the «Storage» mode.
Hold the start button pressed (min. 5 seconds) to switch the device from the "Active"
mode back to the "Storage" mode.

EXTERNAL DEVICES CONNECTION
The actuators are connected to the counter via outputs out 1 иout 2, which are of the
type "Open-drain".
Permissible load for each digital output is 2 A
To increase the load on the device outputs, it is necessary to use an external relay. The
relay connection scheme is shown below.

4 VEGA LORAWAN CONFIGURATOR
The "Vega LoRaWAN Configurator" application (hereinafter referred to as the
configurator) is intended for setting up the device via USB.
The configurator has two modes of operation - "Simple" and "Expert". In the "Simple"
mode, only basic settings are available. In the "Expert" mode, the basic settings, advanced
settings and the ability to check the coverage area of the signal from the gateways are
available. Next, the work of the application is considered in the “Expert”mode.
INTERFACE OF THE APPLICATION
The "Vega LoRaWAN Configurator" application does not require the special installation.
When the executable file is launched, the window for working with the application appears.
The menu on the left allows you to switch between the “Simple”and “Expert”modes,
select the device model, connect to the device or disconnect from it, get and apply settings.
The application window contains three tabs –Device info, LoRaWAN settings and device
settings.
The language selection menu is in the upper right corner.

CONNECTION TO THE DEVICE
For the connection to the device, perform the following steps:
1. Connect the USB cable to the device.
2. Start the "Vega LoRaWAN Configurator" application.
3. Click the "Connect" button in the menu on the left.
The application automatically recognizes the type of device, and the device selection
menu becomes inactive.
To read the settings from the device, you need to click the "Get settings" button, until
this point the application will display the default settings or from the last connected device.

“DEVICE INFO” TAB
The "Device info" tab displays information about the device, its current status, and also
the data needed to register the device in the LoRaWAN network.
ABP info - displays the data necessary to register the device in the LoRaWAN network
with ABP method (Activation By Personalization).
OTAA info - the data required to register the device in the LoRaWAN network with OTAA
method (Over The Air Activation) is displayed.
Regional info (not displayed in the "Simple" mode) - shows the frequencies of the JOIN
channels and the second receiving window. These frequencies can be changed in the
"LoRaWAN Settings" tab when selecting a frequency plan.
Device info - the configurator reads information about the device model, its firmware
and automatically corrects the device's time when connected to it.

Revision 09 –04 May 2018
Update firmware - allows you to select the firmware file from your computer's hard
drive and load it into the device. The device will automatically disconnect from the
configurator when the download is complete. The current version of the device firmware can
be downloaded from iotvega.com.
Network info - shows whether the device is connected to the LoRaWAN network and its
network address.
Join network button - launch the LoRaWAN network connection procedure with the
previously selected ABP or OTAA method. If the device is already connected to the network,
reconnection procedure will occurs.
Link check (not displayed in the "Simple" mode) - when pressed, the device sends a
special signal to the LoRaWAN network, in response to which the network informs it of the
number of gateways that received this signal and the signal quality. This button only works
when the device is connected to the network.
Device output (not displayed in the "Simple" mode) - monitoring the device status, all
events in real time are displayed.
“LORAWAN SETTINGS” TAB

device sends requests for connection to the network on this "join" channels. The remaining
channels that the device should use can be transferred by the LoRaWAN network server during
the device activation procedure (only OTAA).
If you select "Custom" in the "Region" field, you must manually specify the frequencies
that the device will use. To do this, click the "Edit" button, the channel frequency editing
window will appear:
