Detailed Operation
System Info
The System Info page includes information about the software and database versions of the MX20. The data
port status is also displayed. The Data port status description allows you to verify correct system installation
and to monitor the health of each of the devices sending information to the MX20. Use this information when
you contact your dealer or the factory.
GPS and Data Link Status
For GPS/UAT equipped installs, the SYS/INFO page shows additional details for both the internal GPS engine
and the data-link status. When the MX20 is connected to a GDL 90 UAT, only the ADS-B Data Link Status line
is present because there is no differentiation between ADS-B and TIS-B target data.
GPS satellite usage and signal strength are presented in the upper right of the info page in addition to each
satellite’s position in the sky. If no GPS is installed in the MX20, the text “Internal GPS Not Available” will be
shown.
Data-link information is monitored as follows:
HB Heart-Beat from the UAT data-link radio
ADS-B ADS-B broadcast packets received
FIS TX Textual weather data packets received
FIS WX Graphical weather data packets received
