GENERAL INFORMATION
1.1 INTRODUCTION
This manual contains information relative to the physical, mechanical, and electrical characteris-
tics and installation procedures for the KN 62/62A/64 DME. The KN 64 has lower output power
than the KN 62/62A. The KN 64 is not TSO’ed.
1.2 EQUIPMENT DESCRIPTION
The KN 62/62A/64 is a panel mounted, 200 channel DME employing the latest state of the art sol-
id-state transmitter and large scale integrated circuit (LSI) technology. All tuning is done electron-
ically using a single crystal, digital, frequency synthesizer. The unit has a gas discharge display
that simultaneously indicates range, speed, and time-to-station or range and frequency. An auto-
matic dimming circuit adjusts the brightness of the display to compensate for changes in ambient
light level.
Range, speed, and time-to-station are measured digitally, using two LSI,s. Two other LSI circuits
are employed in the digital frequency synthesizer and display circuitry.
The KN 62/62A/64 can be channeled internally using its own frequency selection knobs or exter-
nally from any of the common NAV receiver codes.
The KN 62/62A/64 is an extremely compact DME requiring only 1.3 inches of panel height. It can
be operated with any DC input from 11 to 33 volts. Power consumption is only 15 watts at any
input voltage; thus, forced air cooling is not required.

INSTALLATION
2.1 GENERAL INFORMATION
This section contains information relative to the installation and wiring of the KN 62/62A/64 DME.
A close adherence to methods and procedures discussed herein is required.
2.1.1 KN 62A ONLY
The conditions and tests required for TSO approval of this article are minimum performance stan-
dards. It is the responsibility of those desiring to install this article either on or within a specific
type or class of aircraft to determine that the aircraft installation conditions are within TSO stan-
dards. The article may be installed only if further evaluation by the applicant documents an ac-
ceptable installation and is approved by the Administrator.
2.1.2 KN 62 AND KN 64
The conditions and tests performed on this article are minimum performance standards. It is the
responsibility of those desiring to install this article either on or within a specifice type or class of
aircraft to determine that the aircraft installation conditions are within these perfomrance stan-
dards. The article may be installed only if further evaluation by the applicant documents an ac-
ceptable installation and is approved by the Administrator.
2.2 UNPACKING AND INSPECTING EQUIPMENT
Exercise extreme care when unpacking the equipment. Make a visual inspection of the unit for
evidence of damage incurred during shipment. If a claim for damage is to be made, save the ship-
pingcontainer tosubstantiatetheclaim. The claimshould be promptlyfiledwiththe transportation
company. It would be advisable to retain thecontainer and packaging material after all equipment
has been removed in the event that equipment storage or reshipment should become necessary.
2.3 EQUIPMENT INSTALLATION
2.3.1 AVIONICS COOLING REQUIREMENTS FOR PANEL MOUNTED EQUIPMENT
The greatest single contributor to increased reliability of all modern day avionics is to limit the max-
imum operating temperature of the individual units. While modern day individual circuit designs
consume much less electrical energy, the watts per cubic inch dissipated within avionics units re-
mains much the same due to high density packaging techniques utilized. Consequently, the im-
portance of providing avionics stack cooling is still with us.

BENDIX/KING KN 62/62A/64
Rev 7, November/2004 00144I06.TDC Page 2-2
While each individual unit may not require forced air cooling, the combined heat load of several
units operating in a typical avionics stack will significantly degrade the reliability of the avionics if
provisionsfor stack cooling are not incorporated in the initial installation. Recommendations on
stack cooling are contained in Bendix/King Installation Bulletin #55 and #143 revised. Failure to
provide stack cooling will certainly lead to increased avionics maintenance costs and may void the
Honeywell warranty.
2.3.2 KN 62/62A/64 INSTALLATION (FIGURES 2-1 THROUGH 2-18)
A. Plan a location on the aircraft panel that is clearly visible and within easy access of the pilot.
B.Avoid mounting the KN 62/62A/64 close to heater vents or other high heat sources.
C.Compass safe distance is 8 inches for worst case deflection of one degree.
D.Install the mounting rackin the aircraft using 6-32 x 1/2 flathead phillips screws (P/N 089-
06012-0008) and 6-32 clip nuts (P/N 089-02353-0001). The screws are inserted from the
inside through the holesin the sides of the mounting rack.
E. Connect the harness wires to the connector pins and insert the connector pins into the rear
of the Molex connector.See Section 2.3.3 and Figures 2-1 and2-2.
F.Mount the Molex connector on the twohexspacers at the rear of the mountingrack. Use
two 4-40 x 7/16 pan head,phillips screws (P/N 089-05903-0007) and two #4 split lockwash-
ers (P/N 089-08003-0034). Orient the connector so the polarizer key is closer to the side
next to the antenna connector.
G. Connect the antenna cable to the antenna connector (Figure 2-3).
H. Install the antenna connector in the mounting rackfrom the outside as shownin Figures 2-
14, 2-15. Secure connector in place with three washers and a retaining ring as shown in the
figure.
I. Install the KN 62/62A/64 into the mounting rackand secure byturning the hold down adjust-
ment screw (accessible through a hole in the front panel) clockwise with an allen hex
wrench until it is locked in place (Figure 2-13).
J.The audio output of the KN 62/62A/64 is set for approximately 2mW into 600 ohms at the
factory. If adifferent level is desired, readjust the audio level adjustment, accessible through
the top cover (Figure 2-13).
K. For 066-1068-04 and 066-1088-01 units with backlit Nomenclature refer to interconnect
drawings for interconnect to lighting buss.
L. When operating dual KN 62/62A/64’s, the respective DME’s will interfere with each other
when the NAV frequencies differ by5.3 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 62/62A/64’s should be either turned off or tuned to a different NAV frequency so that
the 5.3 MHz difference is eliminated.

2.3.3 MOLEX CONNECTOR ASSEMBLY (FIGURE 2-1)
A. Solderless Contact Terminal Assembly using Molex Crimper
Refer to instructions in Section2.3.3.
B. Solderless Contact Terminal Assembly using Pliers
1. Strip each wire 5/32” for contact terminal (P/N 030-01107-0030). (The last two digits of
the contact terminal part number indicate the number of terminals furnished).
2. Tin the exposed conductor.
3. Using needle nose pliers, fold over each conductor tab in turn, onto the exposed con-
ductor. When both tabs have been folded, firmly press the tabs against the conductor.
4. Repeat step 3 for insulator tabs.
5. Apply a small amount of solder (using minimum heat) to the conductor/tab connection
to assure a good electromechanical joint.
C. Contact Insertion into Molex Connector Housing
1. After the contact terminals have been installed on the wiring harness, the contact ter-
minals can be inserted into the proper location in the connector housing (P/N 030-
01094-0053). The terminal cannot be inserted upside down. Be sure to push the ter-
minal all the way in, until a click can be felt or heard.
2. The self-locking feature can be tested by gently pulling on the wire.
D. Extraction of Contact from Molex Connector
1. Slip the flat narrow blade of a Molex contact ejector tool, HT-1884 (P/N 047-05009-
0001) under the contact on the mating side of the connector. By turning the connector
upside down one can see the blade slide into the stop.
2. When the ejector is slid into place, the locking key of the contact is raised, allowing the
contact to be removed by pulling moderately on the lead.
3. Neither the contact nor position is damaged by removing a contact; however, the con-
tact should be checked visually before reinstalling in connector, to be certain that
retaining tab ”A” extends as shown (see Figure 2-1) for retention in connector.
2.3.4 DME ANTENNA INSTALLATION
2.3.4.1 General
a. The antenna should be well removed from any projections, the engine(s), and propeller(s).
It should also be well removed from landing gear doors, access doors, or other openings
which will break the ground plane for the antenna.
b. The antenna should be mounted on a bottom surface of the aircraft and in a vertical position
when the aircraft is in level flight.
c. Avoid running other cables or wires near the antenna cable.
d. Avoid mounting the antenna within three (3) feet of the ADF sense antenna or any COMM

BENDIX/KING KN 62/62A/64
Rev 7, November/2004 00144I06.TDC Page 2-4
antenna and six (6) feet from a transponder antenna.
e.Where practical, plan the antenna location to keep cable lengthsasshort as possible, and
avoid sharpbends in the cable to minimize the VSWR.
f.To prevent RF interference, the antenna must be physically mounted a minimum distance of
three feet from the KN 62/62A/64.
g. A back-up plate should be used for added strength on thin-skinned aircraft.
h. The antenna should be kept clean. If left dirty (oil covered) the range of the DME maybe
affected.
i. On pressurized aircraft, the antenna should be sealed using RTV (P/N 016-01082-0000)
around the connector and mounting hardware.
j. All antennas should be sealed around the outside for moisture protection.
2.3.4.2 KA 60/61 Installation (Refer to Figure 2-16 and 2-17)
a. Peel the backing off the antenna template and apply template to the aircraft at the desired
mounting location.
b. Drill or cut the proper size holes for mounting the antenna, then remove the template.
c. Using the antenna as a stencil, draw a line around the base of the antenna that will come
into contact with the aircraft. Then carefully scrape off the paint within the stenciled area.
Lightly sand the bare metal with fine sandpaper to insure removal of all paint and protective
coatings.
d. Sand the inside area of the aircraft where the backing plate will be located to remove the
chromate or other protective finish.
e. Apply Alumiprep No. 33 (P/N 016-01127-0000) following the directions on the container to
cleanse the metal of any residue.
f. Apply Alodine No. 1001 (P/N 016-01128-0000) following the directions on the container.
g. Rivet the backing plate (P/N 047-04570-0000) into place, if required.
h. Mount the antenna using #8 star washers (P/N 089-08017-0037) and 8-32 nuts (P/N 089-
02148-0032) included with the antenna.
i. RGU 400 or equivalent coaxial cable is normally used on installations having a cable run of
ten feet or less. For cable runs from ten to twenty feet, use RG 142B/U cable (P/N 024-
00002-0000).
j. Inspect coaxial cable connector for proper center contact, then fasten it securely to the
antenna.
