• Change Parameters
To change the parameters of the serial interface. This menu allows to select the Port (Signal Source)
between UART0 or UART1, the Baud Rate between 4800 or 9600, the Data Bits (Word Length)
between  or 8, the Parity between EVEN, ODD or NONE, the Stop Bits between 1 or 2, the
Polarity between “+” or “-”. Default settings are: Port = UART1, Baud Rate = 4800, Data Bits =
8, Parity = NONE, Stop Bits = 1, Polarity = +.
• Input Data Display
To allow the chart plotter to act as a computer terminal and display the incoming data exactly as
it received.
If the data displayed on the screen is unrecognizable, you may have selected the wrong input
parameters for your particular receiver, for example, NMEA-0182 instead of NMEA-0183. Check
your receiver manual to be sure that you have selected the proper interface format. If the screen
is blank, you may have a broken connection, and no data is being received. Use ‘+’ to stop (or
continue after pause) data displaying, ‘ENT’ to show data in hex or ASCII mode (normal or small)
and ‘ESC’ to exit.
