= <big>'''Definition and Purpose of a Controller'''</big> =
'''SOKOL-K1''' controllers (hereinafter referred to as the '''controller, SOKOL-K1, or the product''') are designed to collect and process environmental meteorological data, store and analyze the entire volume of information in real time, and transmit it via the '''GSM''' network to a server at specified intervals; they also support '''Modbus''' polling and other data retrieval methods.

'''Automatic measurement''' of meteorological parameters: air temperature, atmospheric pressure, relative humidity, wind speed, and wind direction is performed using the anemorumbometer [[Anemometer Sokol-A|'''Sokol - A''']] (hereinafter referred to as '''“Sokol-A,” anemometer''') and the '''[[Sokol-TDV meter|Sokol-TDV]]''' sensor (hereinafter referred to as '''“Sokol-TDV,” TDV sensor''').

More detailed technical specifications are provided in the device's technical data sheet. (To be added in the future)

= <big>'''Charging the battery, external power supply'''</big> =
Before putting the controller into operation, as well as when '''the battery is low''', it must be '''fully charged.''' The battery installed in the controller is charged from '''three power sources:'''

− a '''solar''' panel (sold separately as an accessory for the Sokol-K1 Controller);

− via the '''USB''' port from an external power source;

− via the '''controller’s 12V port''' from an external power source.

'''The solar''' panel is an alternative power source that allows the controller to operate in standalone mode. '''The USB and 12V external power''' connectors are designed to efficiently charge the controller’s built-in rechargeable battery. To do this, connect it to '''a PC’s USB port''' or to a '''12V DC power source.'''

A full charge of the rechargeable batteries takes '''up to 4 hours''' from a '''DC power source.''' If the battery is fully discharged, charging may take '''more than 8 hours'''. When charging the controller '''via USB''', the charging process is very slow '''(starting at 12 hours)'''; if the battery is deeply discharged, charging may take about a day. Therefore, the best way to charge the controller is using an external power source.

You can check the battery charge level either in the '''“SokolCFG”''' configurator under the '''“Status”''' tab, in the '''“Sokol”''' mobile app, or on the [[Natlogger]] server '''(in the “Upow” field'''). The battery is considered fully charged if its voltage is approximately '''4.15±0.05 V.''' The battery is considered discharged if its voltage is less than 3.5 V.

'''Note: If the controller is connected to an external power source but the switch is not set to the ON position (i.e., the device’s internal battery is not activated), the controller will not charge.'''

'''To restart or power off the controller, follow these steps:'''

'''1)''' Disconnect any external power sources

'''2)''' Turn the switch to the '''OFF position (if you do not need to restart the controller, skip step 3)'''

'''3)''' Turn the switch from the '''OFF''' position to the '''ON''' position, then back to the '''OFF''' position, and then to the '''ON''' position again.

= <big>'''Connecting and Configuring via the mobile Sokol App'''</big> =
There are several ways to connect and configure the '''Sokol-K1 Controller:'''

- Escort mobile app (via Bluetooth connection)

After connecting, in the '''Meteo Data''' tab you will see current sensor readings. In the '''Status''' tab, service sensor readings are displayed.

'''Special attention''' should be paid to the parameters:

'''Azimuth, Tilt''' - these should be close to 0 (or 90 depending on '''firmware''').<blockquote>'''''Azimuth and Elevation are used when operating the SOKOL-M1 controller'''''</blockquote>

'''GSM Status and signal strength''' - these parameters help determine why there is no data from the station on the server.

'''A negative GSM signal strength''' means the '''message''' '''cannot be sent.'''[[File:Sokol app meteo data.jpg|border|left|frameless]]
[[File:Sokol app online data 2.jpg|border|frameless]]

== <big>'''Retrieving and Reading GSM Logs'''</big> ==
Retrieving '''GSM logs''' allows you to analyze '''the station's connection to the network''' and track the stages at which a particular '''failure occurs.'''

y retrieving logs, you can:

'''1) Track at which stage the connection failure occurs'''

'''2) Reduce the time needed to diagnose and resolve the problem'''

[https://docs.google.com/document/d/1TZKGScStqkhTJ4yOUh-JaH1CIcn0oPGB/edit?tab=t.0 You can find these instructions here.] (Currently only available in Russian)

= <big>'''Connection and Configuration via the PC Configurator'''</big> =
Once unpacked, the product does not require configuration using standalone software. The controller is factory-calibrated and set by default to a 30-minute message transmission interval. The controller is ready for installation at the site and commissioning. If you need to change the message transmission interval, manually configure the Internet access point settings (not required in most cases), change the operating mode, etc., you must use the '''[https://drive.google.com/file/d/1j8E6x0aW2thIXI3c8o3VTUpnHF6pPLkd/view?usp=sharing Sokol CFG]''' standalone software.

To connect the controller via '''GSM''', first make sure that '''2G''' coverage is available at the connection site. Check that the '''SIM card''' works in a phone. Make sure that an Internet connection is possible with this SIM card.

- Then insert the '''SIM card''' into the slot, aligning the contacts toward '''the center of the controller''' and making sure you hear a '''click'''.

- '''The notched corner''' of the SIM card should '''face down'''.[[File:Sokol-K1 SIM-card 1.jpg|center|frameless|640x640px]]
