INTRODUCTION
This manual is designated for Vega TP-11 device (hereinafter – device, converter)
manufactured by Vega-Absolute LLC and provides information on powering and activation
procedure, control commands and functions of the device.
This manual is targeted at specialists familiar with installation work fundamentals for
electronic and electrical equipment.
To provide the stable radio between the gateway and the end device it is
recommend avoiding the device installation in the places which are
barriers for the radio signal getting through like a reinforced floors and
walls, a basement, an underground facilities and wells, a metal case etc.
The necessary stage for the network deploying including a big quantity
of end devices is a radio planning work with nature experiments
Vega-Absolute OOO reserves the right to make changes to the manual related to the
improvement of equipment and software, as well as to eliminate typos and inaccuracies,
without prior notice.

1 DESCRIPTION AND OPERATION
DEVICE DESCRIPTION
The device Vega TP-11 is designed for reading of values from devices via 4-20 mA
current loop interface and further accumulating and transmitting of this data to the LoRaWAN
network.
Converter can be used for any sensors and industrial equipment with 4-20 mA
interface, temperature sensors, waste sensors, pressure sensors.
The converter is powered by a 6400 mAh built-in battery with service life up to 10
years, provided data transmitted once a day. The converter can be powered by the 10…36 V
external power supply.
There is a function of current value range control in the device while external power
supplying. During device setting via "Vega LoRaWAN Configurator" application, you may set
allowed current value low and high thresholds. When current value measurements are out of
specified current value range then extraordinary communication session appears. Data
collection periods when measurements in current value range and out are set independently.
Converter is an autonomic device and provides connected sensors with 24 V power via
4-20 mA interface.
Vega TP-11 has two ‘open-drain’ outputs so it can be used as a control device. Also
device has two security inputs.
COMUNICATION AND DATA COLLECTION ALGORITHM
The readings collecting from an external device with a configurable period from 5
minutes to 24 hours. The readings stored in the device memory and transmitting during the
next communication session with the LoRaWAN network.
Data collection period when measurements are out of specified current value range set
independently and may be equal from 5 minutes to 24 hours.
The adjustable data transfer period can be from 5 minutes to 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.
When measurements are out of specified current value range the communication
period still the same if parameter “Immediately send data when current is out of range” is not
active.
If that parameter is active and external power supplying, then the alarm message will
be forming and sending during 2 minutes after the moment of current value measurements
are out of specified range. If external power not supplying, then the converter will detect

exceeding the specified limits during the following data collection session according the
schedule only, but the modem will send that data immediately too. Every following message,
which will form according to the data collection period, also will have sent immediately until
the current value measurements are back in range.
With the "Confirmed uplinks" option turned on, the device will send the next packet
only after receiving a confirmation of the delivery of the previous one. If such confirmation
has not received after the fulfilled in the settings uplink number of transmissions, device
completes the communication session until the next one according to the schedule. In this
case, 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.
With the "Confirmed uplinks" option turned off, the device just sends all accumulated
packets to the network in order from the earliest to the latest. There are no checks of package
delivery in this mode. There are no non-transmitted messages in the device memory.
The internal clock is set automatically when device connected to the "Vega LoRaWAN
Configurator" via USB, also adjustable via LoRaWAN.
FUNCTIONAL
Vega TP-11 converter can be either of class A or class C (LoRaWAN classification) and
has the following features:
oAutomatic change from A class to C class when powered from an external
power supply
oADR support (Adaptive Data Rate)
oSending of confirmed packets (configurable)
oExtra communication in case of security inputs actuation
oExtra communication in case of current value measurements are out of specified
range
oTemperature measurement by the internal temperature sensor
oCharge measuring of the built-in battery (%)
oAbility to configure security input triggering on short, open or both cases
oAbility to set different data collection period for case of current value
measurements are out of specified range
oImmediately data sending at moment of message forming for case of current
value measurements are out of specified range

Security inputs of the device are used to connect circuits with the following types of
NO contacts:
- reed switch (Herkon);
- mechanical pushbutton;
- open-drain output.

Vega TP-11 / User Manual

While security input connected the device monitors its state change (closure/unlocking
or both of it – depend on the settings). Should the security input triggering, the device is
activated and sends an alarm message to the network.
For connect an external sensor contacts CL+ и CL- are used. Connection scheme see
on the picture below.
In order to save the battery life of the converter, the 24 V supply
voltage is not continuously supplied. The 24 V voltage is applied to the
4-20 mA device a few seconds before the polling is performed so that
the sensor can turn on and set the current corresponding to the
measured parameter. This time, the so-called "startup time", is a
configurable parameter from the configurator and can be set from 1 to
60 seconds.
The outputs OUT_1 and OUT_2 operate on the principle of open-drain and can be
used to control external devices, such as electric cranes, lighting, sirens and so on. The load
capacity of each output is no more than 200 mA.
