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.

INITIAL STARTUP
Firstly, it is necessary to install SIM into slot on the board and set up the data transmitting
with “Vega NB-IoT Configurator” (See part 4).
Vega NB-11 modem powered by the built-in battery which comes with. After battery
connection the device loading and switch to the ‘Sleep’ mode until the communication session
according with the schedule.
If you need to test the data transmitting, then press and hold the INIT button for the 2
seconds.
CONNECTING VIA USB
The pulse counter can be adjusted with the "Vega NB-IoT Configurator" application
through the USB connection (See part 4).
Before connecting the device to the computer for the first time, you must install the
driver for the COM port stsw-stm32102, which can be downloaded from iotvega.com. After
running the executable file VCP_V1.4.0_Setup.exe, the installer window will appear:

4 VEGA NB-IOT CONFIGURATOR
The "Vega NB-IoT Configurator" application (hereinafter referred to as the configurator)
is intended for setting up the device via USB.
INTERFACE OF THE APPLICATION
The "Vega NB-IoT Configurator" application does not require the special installation.
When the executable file is launched, the window for working with the application appears.
The menu on the left allows you to select the device model, connect to the device or
disconnect from it, and update firmware.
The application window contains three tabs – System, Settings and device manage.

CONNECTION TO THE DEVICE
For the connection to the device, perform the following steps:
1. Connect the USB cable to the device.
2. Start the "Vega NB-IoT Configurator" application.
3. Click the "Connect" button in the menu on the left.
The application automatically recognizes the type of device, and the device selection
menu becomes inactive.
To read the settings from the device, you need to click the "Get settings" button, until
this point the application will display the default settings or from the last connected device.
After making the necessary changes to the settings, you should click the "Apply settings"
button and only then disconnect from the device with the "Disconnect" button. Also, the
application allows to save settings into a file after what you can load it from that file on other
similar devices for speed up the debugging process.

“SYSTEM” TAB
The "System" tab displays information about the device, about modem, and SIM.
Device info - the configurator reads information about the device model, its firmware
and automatically corrects the device's time when connected to it. In that block you can find
out the number of records in the black box and the number of packets sent by the device.
Modem info – in that block information about LTE-modem is displayed.
SIM – identifiers of the SIM card (SIM chip).

Revision 03 – 08 October 2020
“SETTINGS” TAB
The " Settings" tab allows to configure various parameters of the network connection
and device operation.
Connection settings – a group of parameters set up the data collection and transmitting.
Used frequency bands for NB-IoT devices connection can be different for different
cellular operators. You can ask the operator about used band or select all the bands.
Network registration timeout – it’s a period after which the modem will switch to the
‘Sleep” mode when registration waiting. For battery economy it’s better to set minimal period
for which the device can registered in the network in the specific covering conditions.
Cellular operator can give you APN or set it by default if the field is empty.
Time zone set up for the data collection period which is equal to the device time (UTC)
plus time zone. Transmission period is always use UTC time regardless of the time zone setting.
Readings collected at 00:00 if the collection period is 24 hours; at 00:00 and at 12:00 if
the period is 12 hours etc. All readings stored in the device memory until the next
communication session.
Transmission period can be equal to 5, 15, 30 minutes, 1, 6, 12 and 24 hours. When
beginning of communication session, the device starts sending packets with readings from the
earliest packet. The time of data transmitting cannot be specified, it’s defined in random way
for every device in chosen period of transmission from the moment of connection to the
Vega NB-11 / User Manual
18 Revision 03 – 08 October 2020
network. For example, transmission period is 30 minutes, and device was started at 16:40 by
the internal device clock. In random way the device calculate data transmitting time and set it
at 16:41 in the half-hour period from 16:40 to 17:10. Thus, packets from this device will transmit
at 16:41, at 17:11, at 17:41, at 18:11 and so on every 30 minutes by the internal device clock.
By default, packets sent with confirmation and this parameter cannot be changed. The
number of retries is 5.
Guard inputs settings – allows to set up mode of security inputs triggering – when
security circuit is short, open or in a both cases.
MQTT settings – settings of connection with MQTT broker.
“VEGA NB-11” TAB
The “Vega NB-11” tab contains detail information about the connected device, its sensors
and inputs.
Network – displays the current parameters of the connection and allows to control it.
Buttons in this block have logic like INIT button on the board.
Inputs/outputs – displays current parameters of the device and allows to form a packet,
i. e. to collect data from all the inputs and put the packet to the black box until the next
communication session.
Device output – displays device’s events in real time.

5 COMMUNICATION PROTOCOL
Data transmits via MQTT protocol. You should to specify in the device settings the address
and port of the server where the data will be sent. Those settings specified in application “Vega
NB-IoT Configurator”. It must be MQTT broker as a server (received side). You should to specify
in the device settings the address and port of the broker. Also, you should to specify a topic
name where the data published and a client name – the name which the device use for
publishing. All those settings specified in “Vega NB-IoT Configurator” in part “MQTT settings”.
For watching the data sending by the device you should to deploy MQTT broker on a PC and
subscribe some application on MQTT broker.
Vega NB-11 sends the message on the server as a text of JSON format. See example below.
