connected to an autopilot or flight computer on an unmanned aircraft or a control interface on a manned
aircraft.
At the time of installation, the control interface allows the user to input specific information about the
aircraft that is used in Mode S and ADS-B messages. The interface also allows the user to configure the
Baud rate of Com0 and Com1, set the IP address (which will be used for ethernet communication)
configure the weight on wheels method and select Single or Diversity Antenna installation. This data
will be saved in nonvolatile memory and loaded on every power up.
While operating the MXS the serial interface allows the user to change the operating mode, enable Ident,
change emergency status, and get critical system and transponder health information.
To comply with 14 CFR 91.225 with no operating limitations, dynamic control is required.
The MXS Serial interface is defined in ICD02373.
