Порты 3,4 (UART) разъёма UEXT2 подключены к чипу [[SC16IS752]] и присутствуют только в модификациях с этим чипом (опции GPS или RS-485).  
Ports 3,4 (UART) of the UEXT2 connector are connected to the chip [[SC16IS752/en]] and are present only in modifications with this chip (GPS or RS-485 options).  
Эти порты подключены параллельно трансиверу [[RS-485]], их невозможно использовать одновременно с [[RS-485]].
These ports are connected in parallel to the transceiver [[RS-485/en]] and cannot be used simultaneously with [[RS-485/en]].
