- +
-Настройка контроллера при его первом запуске или после его перепрошивки может осуществляться следующими способами: +
-  * По сети Ethernet; +
-  * Через UART-консоль. +
- +
-Для настройки нонтроллера по сети Ethernet подключите контроллер к локальной сети с настроенным и работающим сервером DHCP. Определите новый IP-адрес контроллера (MAC-адрес контроллера указан на нижней части корпуса контроллера). Например, в маршрутизаторах Mikrotik это можно сделать в меню IP -> DHCP Server -> Leases. Далее подключитесь к контроллеру с помощью любого ssh-клиента, например, Putty под ОС Windows.+
  
-Для подключения через UART-консоль подключите контроллер к компьютеру с помощью любого преобразователя USB-UART (см. п. "UART консоль").+Setting up the controller at its first start or after flashing it can be done in the following ways: 
 +  * Via Ethernet network; 
 +  * Via UART console.
  
-По-умолчанию пароль для пользователя "root" - "1234".+To configure the controller over Ethernet, connect the controller to a local area network with a configured and running DHCP server. Determine the new IP address of the controller (the MAC address of the controller is located on the bottom of the controller case). For example, in Mikrotik routers, this can be done in the menu IP -> DHCP Server -> Leases. Next, connect to the controller using any ssh client, for example, Putty under Windows OS.
  
-При первом запуске будет предложено: +To connect via the UART console, connect the controller to the computer using any USB-UART converter (see p. "UART console").
-  * Задать новый пароль для пользователя root; +
-  * Если контроллер подключен к сети с доступом в сеть Internet, то будет автоматически определен часовой пояс, язык для системы и раскладка клавиатуры; +
-  * Далее будет предложено зарегистрировать в системе нового пользователя и задать для него пароль (рекомендуется это сделать). Ввод данных о пользователе можно пропустить, нажав клавишу Enter на запрос о полном имени пользователя.+
  
 +The default password for the "root" user is "1234".
  
-===== Полезные ссылки =====+On first launch, you will be prompted for: 
 +  * Set a new password for the root user; 
 +  * If the controller is connected to a network with access to the Internet, the time zone, language for the system and keyboard layout will be automatically determined; 
 +  * Next, you will be prompted to register a new user in the system and set a password for him (it is recommended to do this). User data entry can be skipped by pressing the Enter key when prompted for the user's full name.
