1 DEVICE PURPOSE AND OPERATION PRINCIPAL
DEVICE PURPOSE
Vega NB-11 pulse counter is designed for counting of pulses incoming to 4 independent
inputs, further accumulating and transmitting of this information in NB-IoT network.
In addition, Vega NB-11 can be used as a security device – two additional inputs operate
in security mode, there is also Hall sensor.
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
The counter is powered by a 6400 mAh built-in battery.
OPERATION ALGORITHM
The readings collecting from the meter with a configurable schedule. The readings
stored in the device memory and transmitting during the next communication session with the
NB-IoT network.
Data are transferred with a configurable schedule too. Data can be transferred in random
point in time during set period or in the set time. At the next communication session, the device
starts sending accumulated packets with readings, from the earliest to the latest.
The device operates with confirmation all the time and send the next packet only after
receiving a confirmation of the delivery of the previous one. If such confirmation was not
received, NB-11 completes the communication session until the next one according to the
schedule. Herewith, the device continues to collect data according to the data collection
period and store it in memory. Non-transmitted packets remain in the device memory until the
next communication session.
The internal clock is set automatically when device connected to the "Vega NB-IoT
Configurator" via USB.

FUNCTIONAL
Vega NB-11 pulse counter has the following features:
Four pulse inputs for connecting the external devices with pulse output
Two inputs operating in the «security» mode for connecting the external leakage
and safety sensors, etc.
Queue of sending when delivery is not possible
Time referencing of readings by internal clock
Communication in case of security inputs or Hall sensor actuation
Temperature measurement
Charge measuring of the built-in battery (%)
Ability to filter the pulses by the duration
MARKING
Device marked with sticker that contain the next information:
Device model;
IMEI;
Month and year of manufacture.
Sticker located in three places – on device case, in factory certificate and on the packing
box.

CONTACTS
When connecting a radio modem to external devices, consider the internal circuitry of
its pulse inputs shown below.
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 pulse counter allows to connect circuits with the following types of NO contacts:
reed switch;
mechanical pushbutton;
open-collector output.
Equipment with NAMUR pulse output is not supported
Polarity effects only "open collector" circuits.
There are two security inputs on the board. The device monitors status changes on the
security inputs and when the security input triggers, the device is activated and sends an alarm
message to the network.
