Note
Pressing “ESC” instead of “OK” leaving the “NMEA Compass” dialog, all previously configured
changes of single settings will not be adopted.
Port
This setting defines, which communication port is connected to the external compass.
o
The communication port can be changed by pressing one of the visible hotkeys, e.g.: “No
Compass”, “COM1” or “COM2” (s. Figure 153, positions 1, 2 or 3), or the hotkey “Edit Value”
while menu item “Port” is marked (s. Figure 153, position 4).
Using the hotkeys 1, 2 or 3 on the top level dialog “NMEA Compass Configuration” (s. Figure
153), the value of the “Port” setting can be changed without opening the corresponding dialog.

o
Choose the new setting using one of the hotkeys (s. Figure 154), which will then appear in the
“New Setting” field.
Selecting “COM1” or “COM2” (s. Figure 154, positions 2 and 3) configures the corresponding
communication port as the input port for the external compass data. By choosing “No
compass” setting (s. Figure 154, position 1), the external compass data will be ignored. “No
compass” has to be selected, if no external compass is connected, in order to avoid displaying
the corresponding warning on the “Bearing” page (“No Compass” warning).
o
Press the hotkey “Set Default” to use the default value (“No Compass”).
o
Confirm the setting with “OK” or leave the dialog without adopting the new value by pressing
“ESC”.

The default value for baud rate of the NMEA interface is 4800, in compliance with the standard for
NMEA 0183, version 3.01. The baud rate can be changed using this menu item.
For further information please see the document “NMEA-Protocol Description (RT-500-M & RT-800)”.
