2.5.2.4 Serial Port Configuration (UART CONFIG)
The AlphaLine instrument is equipped with 4 serial ports (also called UART or COM).
The settings of the serial ports are divided over two screens as shown in Figure 35: UART Screen 1 on page 40 and
Figure 36: UART Screen 2 on page 40. Use the < or > button to toggle between the screens.
The default setting for NMEA (IEC 61162-1) data is 4800 baud, 8 databits, 1 stopbit. The default setting for Modbus over
serial port is 19200 baud, 8 databits, 1 stopbit and EVEN parity. See also Default Values AlphaLine Instrument on page
25.
Select and configure NMEA when a sensor is connected with the standard NMEA signals. Select ModbusMaster when
an interface (such as Analog Interface Mk.2 or AlphaTurn Interface Mk.2) is used.
