Select Serial Ports and Baud Rates:
As mentioned above, each of the MX9400’s serial ports is designated for specific
tasks. The default configuration of WinFrog’s
Configure MX Serial Ports
dialog box
(as seen above) reconfigures the MX9400’s ports’ duties so that the MX9400 uses
Port 1 for both input of CDU commands and output of Instrumentation/Raw data and
NMEA messages.
This dialog box also allows you to define which Data Items are to be output by the
MX9400. The
