Setting Disp-Cntrl for an input port must correspond to setting a display output
on the same output port. (e.g. if serial port 6 output is set to MX-20 or Traffic-Alert
then serial port 6 input can be set to Disp-Cntrl to enable control).
(4)
For proper traffic and status presentation on legacy displays, review display
settings in paragraphs 7.1.2, 0 and 0and set accordingly.
(5)
When using the FFS Wi-Fi transceiver, ensure port is configured for Traffic Alert.
(6)
Configure at baud rate of 38400 when using Chelton FlightLogic display. Ensure
CSA bit is set per Section 5.2.2.12.4.2.

Altitude Altitude data. Format for sending altitude to a transponder
Output or display using the protocol in Section 4.1.
Display Ownship data, traffic reports, and FIS-B data. Format for
Output the Aspen, GMX-200, Chelton displays, or other displays
using the GDL/FDL protocol. The corresponding serial
port input can be configured to Disp-Cntrl to enable
display control input.
Display Ownship data, ADS-B traffic data, and FIS-B data. Format
Output for sending unprocessed, uncorrelated, and un-prioritized
raw ADS-B messages. Traffic must be processed in
another device to meet TSO-C195a ASSAP installation
requirements.
Display Ownship data, traffic reports, and FIS-B data. Format for
Output the MX-20. The corresponding serial input port can be
configured to Disp Cntrl at the same baud rate to enable
display control input.
Table 6. Serial Port Output Baud Rate Settings
These baud rates are typical for RS-232 or RS-422 equipment but
the correct rate must be selected to match the interfacing
equipment's configured or default baud rate.
These high baud rates are not normally recommended for RS-232
serial ports.
