In the pulse mode the modem counts the number of pulses at the input. Fixation is by
the impulse slump. 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 choose the event for security input triggering via the “Vega NB-IoT 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).
