If any port is configured with these settings on a system with a KGX control panel installed, the KGX control
panel does not accept inputs and instead mirrors the control inputs coming from the transponder or the
display. If control input is lost from another device for 60 seconds, then the KGX control panel takes
over the role as the primary controller.
Table 3006. Serial Port Input Baud Rate Settings
Setting
Description
4800, 9600, 19200,
38400, 57600, 115200
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.
230400, 460800
These high baud rates are not recommended for RS-232 serial ports.

Interface
Description
UNUSED
(Not Used)
-
No connection to serial port
Alt-Encoder
(Encoded
Altitude)
Altitude Output
Altitude data. Format for sending altitude to a transponder or
display using the protocol in Paragraph 2.
Xpndr-Monitor
(XPDR Monitor)
Control Input
Sends requests for squawk code and IDENT input data.
(Xpndr-Monitor Protocol) This selection requires both serial input
and output connections.
2
Traffic-Alert
(TIS/FIS)
Display Output
Ownship data, traffic reports, and FIS-B data. Format for 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.
3 5 6
Pass-Thru
(ADS-B Pass
Thru)
Display Output
Ownship data, ADS-B traffic data, and FIS-B data. Format 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.
3
MX-20
(MX-20)
Display Output
Ownship data, traffic reports, and FIS-B data. Format for the
MX-20. The corresponding serial input port can be configured to
Disp Cntrl at the same baud rate to enable display control input.
