1 DESCRIPTION AND OPERATION
DEVICE DESCRIPTION
Vega SH-2 modem is designed for collection the data from external connected
devices, further accumulating and transmitting of this information in the LoRaWAN or LTE
NB-IoT network.
The modem collect the data from the external devices with configurable period of 5,
15, 30 minutes, 1, 6, 12 or 24 hours. Collected data is saved in modem memory as a packet
with specified time of collect and transmitted at the next communication session with
LoRaWAN network. Memory can hold up to 100 packets.
The modem has two digital inputs which may be configured as pulse or security.
Besides the device has two analog inputs, 1-Wire and RS-485 interfaces.
Communication period can be equal to 5, 15, 30 minutes, 1, 6, 12 and 24 hours. While
communication session the modem transmitting saved packets from the earliest to the latest.
The modem is powered by a one or two 6400 mAh built-in battery or an external
power supply 4.5…55 V.
The internal clock is set automatically when device connected to the "Vega LoRaWAN
Configurator" via USB, also adjustable via LoRaWAN.
The modem can transmit collected data via LoRaWAN or LTE NB-IoT technology (see
part 4).

In the pulse mode the modem counts the number of negative pulses at the input. In the
security mode the modem monitors the input state change and send an alarm message into
the network by the one of events: security circuit close, unclose or both of it. You can specify
the event for security input triggering via the “Vega LoRaWAN Configurator” application.
Analog inputs ADC1 and ADC2 may be used for measuring an external voltage from 0
to 21 V.
RS-485 (modbus) and 10Wire interfaces cannot connecting at the same time. Switching
between two interfaces carried out with jumpers on the XP4 and XP5 connectors on the
board.
1-Wire interface allows to connect is up to 10 external thermistors (see part 4).

INDICATION
There is a red LED on the board. The indication is only used when the device is
activated in the LoRaWAN network, when data transmitting via NB-IoT technology and when
the operating modes are changed. Also there is a green LED which used only for configuring
during manufacture.
