1 DESCRIPTION AND OPERATION
DEVICE DESCRIPTION
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
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 6400 mAh built-in battery.
COMUNICATION AND DATA COLLECTION ALGORITHM
The readings collecting from the meter with a configurable period 5, 15, 30 minutes, 1,
6, 12 or 24 hours. The readings stored in the device memory and transmitting during the next
communication session with the NB-IoT network.
The adjustable data transfer period can be equal to 5, 15, 30 minutes, 1, 6, 12 and 24
hours. Data transferring in random point in time during set period. 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:
oFour pulse inputs for connecting the external devices with pulse output
oTwo inputs operating in the «security» mode for connecting the external leakage and
safety sensors, etc.
oQueue of sending when delivery is not possible
oTime referencing of readings by internal clock
oCommunication in case of security inputs or Hall sensor actuation
oTemperature measurement
oCharge measuring of the built-in battery (%)
MARKING
Device marked with sticker that contain the next information:
oDevice model;
oIMEI;
oMonth and year of manufacture;
oQR-code containing IMEI for automatized count.
Sticker located in three places – on device case, in factory certificate and on the packing
box.

CONTACTS
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.

HALL SENSOR
The device has Hall sensor which located on the board edge on the bottom side. When
the magnet is brought up the sensor triggered, and the device can form the alarm message
which immediately transmitted to the server.

BUTTONS
There are two buttons on the board which can help you to manage the device. Buttons
are described in the table below.
Action Result
RESET
Short pressing Device reloading
INIT
Pressing for 1 second Registration at the network
Pressing for 2 seconds Data transmitting
Pressing for 3 seconds LTE-modem switching off
When you hold down the button, the red LED starts flashing once a second, which will
help you to find out the duration of pressing. Pressing for 1 second corresponds to one flash
of the LED, pressing for 2 seconds corresponds to two and so on.
