Interface
Description
GPS Output
The KGX series models with internal GPS can output GPS position, velocity,
time, and integrety data thru the RS-232 and/or ARINC 429. Internal GPS models
automatically output GPS data in the FFS/Chelton protocol on Port 1. Also, the
ARINC 429 output port can be configured to output ARINC 743 A/B compatible
GPS messages.
GPS Predictive RAIM
The KGX series models with internal GPS can receive and respond to predictive
RAIM (PRAIM) requests for a destination or alternate waypoint through the RS-232
or ARINC 429. A FMS can request the GPS to provide a RAIM prediction on serial
Port 1 input or a PRAIM configured ARINC 429 input. The PRAIM responses
are sent on serial Port 1 RS-232 or the 743 A/B configured ARINC 429 output
respectively.
(c)
ARINC and serial ports are set by the installer to specific data formats which supply the
necessary data interfaces. All data interface types (except display output) from Table
3004 can be configured to one and only one ARINC or serial port.
(d)
If multiple ARINC/serial ports are set to the same data interface type then only one port is
actually configured and all other settings of the same data interface type are ignored. The
data interface order of precedence is as follows:
• ARINC 429 ports take precedence over UART serial ports
• Lowest port channel number takes precedence over higher channel number.
(e)
For example, if the KGX has an internal GPS and serial IN 1 is set to GPS-Internal
and ARINC IN 1 is set to GPS-743, then the KGX will not receive GPS data from the
internal GPS.
(f)
Set only one control input, only one altitude input, and only one GPS input. Inadvertently
setting more than one of the same input type can result in the correct input data not
being received.
(g)
Only one function can typically be set to either the input or output of each bidirectional
serial Port (2, 3, 5, or 6). If the serial port input is set to a function then the output must
be set to UNUSED and vice versa. If a serial port’s input and output are both set only
one setting is configured and unexpected operation can occur. The exception is if a
display output is set on a port output then the port input can be set to display control
otherwise the input must be set to UNUSED.
(h)
Control input is not required for receive only systems.
(i)
Using the Android tablet ADS-B MPI application significantly improves system
configuration and troubleshooting through use of a GUI. The ADS-B MPI application
includes additional and improved automated status feedback and automatic enforcement
of the above configuration rules that is not available when configuring the system with
the KGX control panel or the simple terminal program MPI interface. The ADS-B
MPI application requires use of a serial-to-WiFi transceiver, KGW WiFi module, PN
89000016-002, properly connected to Port 3 or Port 5.

Serial Port Input Configuration
(a)
Serial port input data formats and baud rate settings are described in Table 3005 and
Table 3006.
