    Connect RS232/UART to sevocontroller. Connect as on figure external led and resistor. Give power. When striking the button "Подключить" (Connect) led must once On/Off (flash). If You have no flashings, that check the number COM port. And correctness of the montage RS232/UART. If led blinks (1 once), that check the chain from output RS232/UART before conclusion 2 and 3 AtMega88 (DIP).
