User manual
LoRaWAN Pulse Counter Vega SI-13 is used for reading of
values from metering instruments, such as water-, electricity
and heat meters via RS-485 and RS-232 interfaces or via
pulse inputs and further transmitting of this data to
LoRaWAN network.
Vega SI-13 can be used as a security by sending alarm signal
in case a specific contact pair is closed.

INTRODUCTION
This manual is designated for Vega SI-13-232 and Vega SI-13-485 pulse counters
(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-13 has two design options, varying by data exchange interface:
Vega SI-13-232 with RS-232 interface;
Vega SI-13 -485 with RS-485 interface.
Vega SI-13 pulse counter is designed for counting of pulses incoming to 2 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-13 can be used as a security device - all inputs can be configured as
security inputs.
The pulse counter can be used for any utilities’ meters and industrial equipment with RS-
232 and RS-485 interfaces or pulse outputs, including water-, electricity-, and heat meters.
Vega SI-13 can work as a wireless modem or query some meters’ models.
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 8…36 V 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:

- reed switch (Herkon);
- mechanical pushbutton;
- open-collector output.
Equipment with NAMUR pulse output is not supported
Any input can be configured for work in the "Security" mode with special 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.
