SYSTEM INSTALLATION MANUAL
89000016
• Low v7 VDC power (J1-18 & J1-2)
• Serial Port 3 RS-485 communication (J1-20 & J1-28).
NOTE:
The KGX control panel uses Serial Port 3 so when it is installed, the Serial
Port 3 RS-232 pins (J1-23 & J1-24) must not be connected to other equipment
(Display, etc.)
NOTE:
The REM ON pin (J1-32) MUST be connected to ground when not using remote
power control or a KGX control panel is not installed for the system to power on.
(3)
The KGX control panel interface connections are shown in Table 1014.

Configurable Serial Interfaces
(1)
There are nine configurable serial interfaces available on the KGX:
• Six UART style serial port interfaces (Ports 1, 2, 3, 4, 5 and 6)
• Two ARINC 429 input interfaces (429 IN1 and 429 IN2)
• One ARINC 429 output interface (429 OUT1).
NOTE:
Refer to Paragraph 3.C. in the CONFIGURATION, CALIBRATION, AND
CHECKOUT section for detailed serial and ARINC port configuration information.
(2)
Serial Port- RS-232/RS-422
(a)
Four UART style (serial port) serial interfaces are available on the KGX:
• Serial Port 1 - RS-232 transmit and receive capability
• Serial Port 2 - RS-232 transmit and receive capability
• Serial Port 3 - RS-232 transmit and receive capability
• Serial Port 4 - RS-232 receive-only capability
• Serial Port 5 - RS-232 transmit and receive capability
• Serial Port 6 - RS-232 or RS-422 bidirectional (transmit and receive) capability.
NOTE:
Serial Port 6 can be optionally configured for RS-232 serial interface on
Pins J1-8 and J1-38.
(b)
The Serial ports can be software configured for various protocols and baud rates.
(c)
The UART style serial interface pin connections are shown in Table 1015.
NOTE:
Refer to Paragraph 3.C. in the CONFIGURATION, CALIBRATION, AND
CHECKOUT section for detailed serial and ARINC port configuration
information.
