Molex Connector Assembly - Honeywell Bendix/King KN 63 Installation Manual

bars (047-04218-0001). Secure the mounting rack (047-04219-0001) with the two
hold down bars under it using four 8-32 flat head phillips screws (089-05442-0010),
four 8-32 hex nuts (089-02015-0037), and four #8 lock washers (089-08111-0034).
Install the KN 63 in the mounting rack so the connectors are on the same end as
the hold down clamp. Tighten the hold down screw to secure unit in place.
H. Connect the harness wires to the connector pins (030-01107-0015) and insert the
connector pins through the connector hood (088-00752-0000) into the rear of the
Molex connector (030-01094-0056). Mount the Molex connector and connector
hood to the front of the unit using two 4-40 pan head phillips screws (089-06541-
0000). The connector must be turned so the polarizer key aligns with the slot in the
printed circuit board. Use a cable tie (091-00109-0001) to bundle the wires at the
rear of the connector hood.
I. Connect the antenna cable to the antenna connector.
J. The audio output of the KN 63 is set for approximately 2mw into 500 ohms at the
factory. If a different level is desired, remove the rear plate and the dust cover.
(Each are held in place with three screws.) The audio level adjustment is then ac-
cessible through a hole in one of the inner covers.
K. The KN 63 suppression input/output fully meets ARINC specifications and is com-
patible with all DME's and transponders meeting ARINC specifications. Some
transponders will accept ARINC suppression but do not generate a supression out-
put for the KN 63. These transponders are compatible with the KN 63. Some
DME's generate a suppression output that is incompatible with the KN 63. They
will be damaged by the KN 63 and, therefore, are incompatible. The installer must
determine the compatibility of the suppression in the transponder and, possible,
DME with the KN 63 suppression prior to making the installation. This information
will be available in the respective equipment service bulletins or installation manu-
als.
L. When operating dual KN 63's, the respective DME's will interfere with each other
when the NAV frequencies differ by 5.3 MHz (for example, 108.00 MHz and 113.3
MHz). This interference results in premature flags or loss of "lock-on". Should this
occur, one of the KN 63's should be either turned off or tuned to a different NAV
frequency so that the 5.3. MHz difference is eliminated.
