INTRODUCTION
This manual is designated for Vega SI-12 RELAY 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.
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 RELAY pulse counter is designed for counting of pulses incoming to 4
independent inputs, further accumulating and transmitting of this information to the
LoRaWAN®network, and for controlling low-power actuators by means of built-in relays.
In addition, Vega SI-12 RELAY can be used as a security device - all inputs can be
configured as security inputs.
The counter has two relay 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 dry reed switch 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 can be powered by the 8-35V and output current not less than 150 mA
external power supply.
COMUNICATION AND DATA COLLECTION ALGORITHM
Vega SI-12 RELAY operates in modes listed below:
“Storage” – is a mode for storing and transporting. In this mode the device does not
communicate regularly with the network.
“Active” – is a main mode of device operation.
Before start using you need to switch the device out of “Storage” mode.
Vega SI-12 RELAY supports two activation methods in the LoRaWAN®network - ABP and
OTAA.
ABP method. After pressing the start button, the device immediately starts working in the
"Active" mode.
OTAA method. After pressing the start button, the device makes three attempts to
connect to the network within the set frequency plan. After the activation in the LoRaWAN®
network is confirmed, the device sends a signal (LED flashing for 5 seconds) and switches to
the "Active" mode. If all attempts fail, the counter will continue to accumulate data and will
attempt to connect to the network every 6 hours.

Hold the start button pressed (min. 5 seconds) to switch the device from the "Active"
mode back to the "Storage" mode.
When switching to the "Storage" mode, all readings from the pulse inputs
accumulated in the device memory are reset
The device forms the data packet with current state with a configurable period from 5
minutes to 24 hours. The packets stored in the device memory and transmitting during the next
communication session with the LoRaWAN®network.
Examples
If the data collection period is set to 24 hours the packet is formed at 00.00 on the
internal clock of the device
If the data collection period is 12 hours then at 00.00 and at 12.00, and so on.
The adjustable data transfer period can be from 5 minutes to 24 hours. When beginning
of communication session, the device starts sending packets with readings from the earliest
packet. The time of data transmitting cannot be specified, it’s defined in random way for every
device in chosen period of transmission from the moment of connection to the network.
Example
Transmission period is 30 minutes, and device was started at 16:40 by the internal device
clock. In random way the device calculate data transmitting time and set it at 16:41 in the half-
hour period from 16:40 to 17:10. Thus, packets from this device will transmit at 16:41, at 17:11,
at 17:41, at 18:11 and so on every 30 minutes by the internal device clock.
The internal clock is set automatically when you connect to the device through USB, also
can be adjust via LoRaWAN® network.
