INTRODUCTION
This manual is designated for Vega SI-13-232 and Vega SI-13-485 modems (hereinafter
– the modem) manufactured by Vega-Absolute OOO and provides information on powering
and activation procedure, control commands and functions of the modem.
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.
The current revision of the manual describes the functionality, characteristics and
protocol implemented in the latest firmware version of the device.

1 DESCRIPTION AND OPERATION
DEVICE DESCRIPTION
Vega SI-13 has two design options, varying by data exchange interface:
oVega SI-13-232 with RS-232 interface;
oVega SI-13 -485 with RS-485 interface.
Vega SI-13 modem 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 modem 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 in the transparent mode or pool meters by itself.
Equipment with NAMUR pulse output is not supported
De-bouncing logics with 5 msec time constant is integrated in the modem. The pulse
counting is carried out for frequencies up to 200 Hz.
The modem is powered by an 8…36 V external power supply.
FUNCTIONAL
Vega SI-13 modem is class C device (LoRaWAN classification) and has the following
features:
oOperation as LoRaWAN <-> RS-232 or LoRaWAN <-> RS-485 wireless modem
oIndependent polling of external equipment by custom commands
oADR support (Adaptive Data Rate)
oSending of confirmed packets (configurable)
oInputs can be switched to «security» mode for connection to external leakage
and safety sensors, etc.
oCommunication in case of security inputs actuation
oTemperature measurement
MARKING
Device marked with sticker that contain the next information:
oDevice model;

Vega SI-13 / User Manual
6Revision 13 - 23 September 2020
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.

Revision 13 - 23 September 2020
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 modem 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.
