INTRODUCTION
This manual is designated for Vega SI-12 pulse counter (hereinafter – the counter)
manufactured by Vega-Absolute OOO and provides information on powering and activation
procedure, control commands and functions of the counter.
This manual is targeted at specialists familiar with installation work fundamentals for
electronic and electrical equipment.
To provide the stable radio between the gateway and the end device it is
recommend avoiding the device installation in the places which are
barriers for the radio signal getting through like a reinforced floors and
walls, a basement, an underground facilities and wells, a metal case etc.
The necessary stage for the network deploying including a big quantity of
end devices is a radio planning work with nature experiments
Vega-Absolute OOO reserves the right to make changes to the manual related to the
improvement of equipment and software, as well as to eliminate typos and inaccuracies,
without prior notice.

1 DESCRIPTION AND OPERATION
DEVICE DESCRIPTION
Vega SI-12 pulse counter is designed for counting of pulses incoming to 4 independent
inputs, further accumulating and transmitting of this information to the LoRaWAN network.
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. The counter also can be
powered by the 5V external power supply.
The device is powered by a non-rechargeable lithium-thionyl chloride
(LiSOCl2) battery
Attempts to charge the battery may result in fire
COMUNICATION AND DATA COLLECTION ALGORITHM
The readings collecting from the meter with a configurable period from 5 minutes to
24 hours. The readings stored in the device memory and transmitting during the next
communication session with the LoRaWAN network.
The adjustable data transfer period can be from 5 minutes to 24 hours. Data
transferring in random point in time during set period. At the next communication session, the
device starts sending accumulated packets with readings, from the earliest to the latest.
With the "Confirmed uplinks" option turned on, the device will send the next packet
only after receiving a confirmation of the delivery of the previous one. If such confirmation
has not received after the fulfilled in the settings uplink number of transmissions, device
completes the communication session until the next one according to the schedule. In this
case, the device continues to collect data according to the data collection period and store it
in memory. Non-transmitted packets remain in the device memory until the next
communication session.

Vega SI-12 / User Manual
6 Revision 12 – 03 July 2020
With the "Confirmed uplinks" option turned off, the device just sends all accumulated
packets to the network in order from the earliest to the latest. There are no checks of package
delivery in this mode. There are no non-transmitted messages in the device memory.
The internal clock is set automatically when device connected to the "Vega LoRaWAN
Configurator" via USB, also adjustable via LoRaWAN.
FUNCTIONAL
Vega SI-12 pulse counter can be either of A class or C class (LoRaWAN classification)
and has the following features:
oAutomatic change from A class to C class when powered from an external
power supply
oADR support (Adaptive Data Rate)
oSending of confirmed packets (configurable)
oSimultaneous readings from 4 independent inputs
oTwo operating modes: "Active" and "Storage"
oInputs switching to the “Security” mode for connection of leakage, safety, and
other external sensors
oSaving non-transmitted packets in device memory
oTime referencing readings by internal clock
oCommunication in case of security inputs actuation
oTemperature measurement
oCharge measuring of the built-in battery (%)
MARKING
Device marked with sticker that contain the next information:
oDevice model;
oDevEUI;
oMonth and year of manufacture;
oQR-code containing DevEUI for automatized count.
Sticker located in three places – on device case, in factory certificate and on the packing
box.
Besides, there is an additional sticker located on the packing box and contains:
oInformation about firmware version;
oQR-code containing DevEUI and keys for device registration in network via
OTAA method.

Equipment with NAMUR pulse output is not supported
Any input configurable 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.
When connecting a radio modem to external devices, consider the internal circuitry of
its pulse inputs shown below.
