INTRODUCTION
This manual is designated for Vega SI-12 pulse counter (hereinafter –the counter)
manufactured by Vega-Absolute LLC 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.
The counter shall be installed and adjusted by qualified specialists in order
to ensure proper operation of the device.

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,

Moreover this information is repeated in the label-sticker on the housing cover in the
form of a QR code.
The pulse counter uses port 2 for data receiving and sending

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.
