Interfaces General • Serial interfaces are electrically isolated • The serial interfaces use the same connection terminals. You can use either RS232 or RS485 (Changeover via software). RS232 • The interface supports baud rates from 300 to 115200 Baud. • The signals RXD and TXD are available, but without handshake signals. RS485 • The interface supports baud rates from 300 to 115200 Baud. Bus terminator • You can switch up a bus termination via software in the I/O Open module (1nF, 120 Ohm in series).
