10. KGX Interface Details (All Models)
A.
Power Input
(1)
Aircraft power is provided to the KGX through the J1 power and I/O connector. The power
supply input can be 10 to 40 VDC. Use a 2-AMP circuit breaker for power supply protection.
Power input resides on the pins shown in Table 1011.

REM ON must be tied to KGX control panel Pin 7 for remote on/off control or tied to ground for the KGX to
power up.
B.
Personality Module
NOTE:
The personality module is installed to simplify KGX service replacement.
(1)
The PM eliminates the need to reconfigure the KGX if replaced with a new unit for any reason
after initial configuration. Installation specific configuration data is stored in the PM as well
as in the KGX. The installation configuration data in the PM (if present) is copied to the
KGX at power-up.
(2)
Both the PM and the KGX configuration data are stored during the installation configuration
process. The PM is optional but simplifies the process to replace a serviced KGX. Refer to
Paragraph 13 in this section for the detailed installation of the PM.
(3)
The KGX control panel (if used in the installation) also contains a back-up copy of the
installation configuration data. If the PM is not installed, the KGX control panel will
automatically reconfigure the KGX if it is replaced in the installation.
(4)
However, if the KGX control panel is replaced in an installation without the PM, the KGX
must be reconfigured.
(5)
The PM connections are on the pins shown in Table 1012.
