SECTION II

INSTALLATION

2.1 GENERAL INFORMATION

This section contains suggestions and factors to consider before installing the KY 196B. Close
adherence to these suggestions will assure more satisfactory performance from the equipment.

2.2 UNPACKING AND INSPECTING EQUIPMENT

Unpack the equipment carefully and inspect each item for evidence of damage incurred during
shipment. If a damage claim must be filed, save the shipping container and all packing materials
to substantiate your claim. The claim should be filed with the transportation company as soon as
possible. The shipping container and packing material should be saved in any case in the event
that storage or reshipment of the equipment is necessary.

2.3 EQUIPMENT INSTALLATION

The KY 196B installation will conform to standards designated by the customer, installing agency,
and existing conditions as to the unit location and type of installation. However, the following
suggestions should be considered before installing the KY 196B. The installing agency will supply
and fabricate all external cables. The connectors required are supplied by Honeywell International
Inc.. Interconnect diagrams are included in this manual as Figures 2--10 through 2--12. Refer to
table below for compatible installations.

Tabl e 2-- 1

Current Installation -- -- >

*1 Display brightness controlled by dimmer bus not photocell.
*2 Button/Bezel backlighting not operative.
*3 If installation utilizes external audio amplifier.

NOTE: 064--01084--0201 is not compatible with other KY 96A/196A/197A installations, due to the

5 volt panel lighting and Bezel difference.

Use good quality stranded wire with at least 600V insulation that will
not support a flame.

2.3.1 AVIONICS COOLING REQUIREMENTS FOR PANEL MOUNTED EQUIPMENT

The most important contribution to improved reliability of avionics equipment is to limit the
maximum operating temperature of each unit. While modern designs consume less total
energy, the heat dissipated per unit volume (Watts/cubic inch) remains much the same due
to contemporary high density packaging techniques. While each individual unit may or may
not require forced air cooling, the combined heat generated by several units operating in

KY--Series Radio Installation compatibility

KY 196B

VHF COMMUNICATIONS TRANSCEIVER

a typical panel or rack can significantly degrade the reliability of the equipment if provisions
for adequate cooling are not incorporated in the initial installation.

2.3.2 MOUNTING RACK INSTALLATION A. The KY 196B is mounted rigidly in the aircraft panel. Select a position in the panel

that is not too close to any high external heat source. Remember to allow adequate
space for installation of cables and connectors. Avoid sharp bends and placing the
cables too near the aircraft control cables.

B. When installing two or more panel mounted units in a stack, the mounting trays shall be

spaced 0.050 inches (0.127 cm) apart. Current production mounting trays have 0.025
inch (0.064 cm) dimples built in to top and bottom and both sides so that the trays will
automatically be spaced properly.

C. Refer to Figure 2--8 for the KY 196B mounting dimensions. Mark and cut the

mounting holes.

D. Secure the mounting rack to the instrument panel per Figure 2--8. The rear mounting

bosses should be attached to the airframe by means of support brackets.

2.3.3 ANTENNA INSTALLATION

A conventional 50Ω vertically polarized comm antenna is required with the KY 196B. Vertical bent
whip antennas are not recommended. Wideband comm antennas provide efficient operation over
the comm band. Antennas should be installed per manufacturer’s recommendations. Additional
recommendations are as follows:

A. Mount antenna on a flat metal surface or install a ground plane at least 18 inches square.
B. The antenna should be well removed from any projections and the engine(s) and

propeller(s). Also, for satisfactory operation, the antenna isolation between a
communications transmitter antenna and a nav receiver antenna, as well as between
dual comm antennas, should be a minimum of 30dB. VHF antennas mounted on top
and bottom have approximately 30dB isolation. A horizontally polarized nav antenna
and a vertically polarized comm antenna will have practical values from 10 to 30dB.

C. If both comm antennas must be top mounted or both bottom mounted, antenna isolation

between comms may not be adequate to prevent reradiation. In single audio panel
installations, reradiation can be prevented by use of the XMIT--REC interlock. In dual
audio panel installations where simultaneous operation of both comms is desired, the
XMIT--REC interlock is not recommended.

2.3.4 CABLE HARNESS AND CONNECTOR ASSEMBLY

The KY 196B uses a special connector that mates directly with the printed circuit board
inside the unit. Assembly of the connector is as follows:

A. Contact Terminal Assembly using Molex Crimper (See Figure 2--2)

1. Strip each wire 5/32” for contact terminal, PN 030--01107--00XX. Note: The last two
digits of the part number indicates the number of terminals required.

2. Place the conductor tab section of a contact terminal on the appropriate anvil of the
hand crimping tool. Close the crimper until the terminal is held lightly in place.

Page 2-2 10570I01.ZIPCDL

Rev 1 January/2000

BENDIX/KING

KY 196B

VHF COMMUNICATIONS TRANSCEIVER

3. Insert the stripped conductor into the contact until the insulation is even with the side
of the crimper facing the operator, the conductor hits the crimper’s wire stop, or the
insulation contacts the crimpers step--jaw, depending on the type of crimp tool being
used.

4. Squeeze the crimping tool’s handles until the crimp jaws are fully closed or until a
sufficient crimp is obtained. With a step--jaw type crimper, the contact terminal will
have been crimped to both the insulated and bare sections of the conductor.
If single--jaw crimpers are being used, move the contact terminal/conductor
assembly to locate the terminal’s insulation tabs on the anvil of the crimp tool. Crimp
again until the jaws are fully closed or a sufficient crimp is obtained to the insulation.

B. Contact Insertion into Molex Connector Housing
After the contact terminals have been installed on the wiring harness, the contact terminals

can be inserted into the proper location in the connector housing (PN 030--01094--0080).
The terminal cannot be inserted upside down. Be sure to push the terminal all the way in
until a click can be felt or heard. The self--locking feature can be tested by gently pulling
on the wire.

C. Location of Polarizing Key in Housing
Prior to insertion of connector into rear of unit, check polarizing key position between

contacts 8 and 9. Refer to Figure 2--9 to check correct position of polarizing key.
D. Extraction of Contact from Molex Connector

1. Slip the flat narrow blade of a Molex HT--1884 contact ejector tool,
PN 047--05099--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 retaining tab of the contact is raised, allowing
the contact to be removed by pulling moderately on the lead.

3. Neither the contact or position is damaged by removing a contact; however, the
contact should be visually checked before reinstalling to be certain that retaining tab
”A” extends as shown in Figure 2--1 for retention in connector.

E. Coax Connector
Refer to Figure 2--7 for instructions for mounting the right angle coaxial BNC connector to

the coax cable. Install the connector into the mounting rack.

2.3.5 KY 196B INSTALLATION

A. Looking at the top of the unit, make sure the front lobe of the hold--down device is in a
vertical position.

B. Slide the unit into the mounting rack until the front lobe touches the mounting rack.
C. Insert a 3/32” Allen wrench through the hole in the front panel to engage the locking

screw. Turn clockwise until the rear lobe engages the mounting rack. Continue turning
until the unit is secure in the mounting rack. DO NOT OVERTIGHTEN.

D. To remove the unit turn the locking screw counterclockwise, using a 3/32” Allen wrench,

until the unit disengages from the mounting rack. Pull the unit out of the mounting rack
by pulling on the indentations on each side of the unit’s bezel.

2.3.6 MOLEX TERMINAL INSTRUCTIONS The Molex hand crimpers are available under P/N 071--06041--0000, or from Molex under P/N

6115.

Holding the hand crimpers as shown, release the crimper’s ratchet pawl and open by squeezing
tightly on the handles, and then releasing pressure.

FIGURE 2--2 HAND CRIMPER

Close crimpers until ratchet begins to engage. Then insert the terminal into the jaws from the back
side. (See Figure 2--3 and 2--4) For 24 to 30 AWG wire, it will be necessary to start the crimp in
jaw A and then complete it in jaw B. The terminal is in the correct position when the insulation tabs
are flush with the outside face of the crimp jaws.

FIGURE 2--4 TERMINAL INSERTION

Once the terminal is in the correct position, close the jaws gently until the terminal is held loosely
in place. Push the wire stop down so that it rests snugly behind the contact portion of the terminal.

Strip the wire insulation back 1/8 inch and insert the wire through the insulation tabs into the
conductor tabs until the insulation hits the conductor jaw face or until the conductor touches the wire
stop. Squeeze the handles until the crimp jaws close and the ratchet releases. Straighten the
terminal if necessary, then release the plier grips and remove the crimped terminal.

FIGURE 2--5 HAND CRIMPER INSERTION

If too much or too little pressure is needed to release the crimper’s ratchet pawl at the end of the
crimp stroke, the ratchet can be easily adjusted. A spanner wrench provided with the tool can be
used to loosen the lock nut, and rotate the keyed stud clockwise for increased pressure and counter
clockwise for decreased pressure. Once the desired pressure has been set, the lock nut must be
tightened again. Newer models may have a screwdriver adjustment.

2.4 POST INSTALLATION CHECKS

KY 196B

An operational performance flight test is recommended after the installation is completed to insure
satisfactory performance of the equipment in its normal environment. Check all aircraft control
movements to be sure no electrical cables interfere with their operation. To check the
communications transceiver, maintain an appropriate altitude and contact a ground station facility
at a range of at least 50 nautical miles. Then contact a ground station close in. Pull the volume
control out to defeat the automatic squelch feature and listen for any unusual electrical noise which
would reduce the comm receiver sensitivity by increasing the squelch threshold. If possible, verify
the communications capability on both the high and low end of the VHF comm band.

NOTE

As an added precaution before the flight, check the antenna. VSWR
should be checked with an in--line type wattmeter inserted in the
coaxial transmission line between the transceiver and the antenna.
Any problem with the antenna installation will most likely be seen as a
high reflected power. A VSWR of 3:1 will result in a 25% loss of
power.

The brightness of the display can be set for the most pleasing
intensity by placing the unit in Dimmer Adjust mode during low light
level conditions. See Paragraph 3.1 of this manual for Dimmer
Adjust mode operating instructions.

SECTION III

OPERATION

3.1 GENERAL INFORMATION

For a detailed description of the operating controls of the KY 196B refer to the ’Silver Crown +’ pilots
guide (P/N 006--18110--0000) or the aircraft’s flight manual supplement.
Control layout is shown in Figure 3--1.

3.1.1 TURN ON To turn on the radio rotate the Volume (VOL) knob clockwise from the OFF position. When power

is activated the Use and Standby (STBY) windows will display the frequencies and/or mode stored
in the non--volatile memory before power down.

After activating power, pull the VOL knob out to override the automatic squelch and rotate the VOL
knob to the desired audio level. Push the VOL knob back in to activate the automatic squelch.

CAUTION

THE KY 196B SHOULD BE TURNED ON ONLY AFTER
ENGINE STARTUP. THIS IS A SIMPLE PRECAUTION
WHICH HELPS PROTECT THE SOLID STATE CIRCUITRY
AND EXTENDS THE OPERATING LIFE OF YOUR AVIONICS
EQUIPMENT.

3.1.2 TRANSMIT INDICATOR During Comm transmissions, a T will appear between the USE and STBY windows to indicate that

the Mic has been keyed.

3.1.3 MODES OF OPERATION A. Frequency Mode

Frequency selection is accomplished in the Standby Entry mode by changing the frequency
display in the STBY window of the display with the tuning knobs, and then transferring the
selected frequency into the USE window by pressing the Transfer button. The larger tuning
knob will increment or decrement the MHz portion of the display in 1MHz steps with rollover
at each band edge (118 MHz or 136 MHz). the smaller tuning knob will increment or
decrement the KHz portion of the display in 25 KHz steps with the knob pushed in or will
tune both the 8.33 KHz and 25 KHz channels with the knob pulled out. While in the Standby
Entry mode, the transceiver remains tuned to the frequency displayed in the USE window
at all times.

B. Channel Mode

Momentarily pressing the Channel (CHAN) button while in the Frequency mode puts the
radio in the Channel mode. The last active frequency remains tuned and displayed in the
USE window. The last used channel number is displayed in the channel digit unless no
channels have been programmed, in which case the radio defaults to Channel 1 and dashes
are displayed in the STBY window. Turning either tuning knob changes the channel number
and corresponding frequency in the STBY window.
The channels will only increment and decrement to channels that have been programmed.
If there has been no activity for five seconds the radio will return to Frequency mode and
the channel frequency is placed in the STBY window. Pressing the CHAN button before the

10570I01.ZIPCDL
Rev 1 January/2000

Page 3-1

BENDIX/KING

KY 196B

VHF COMMUNICATIONS TRANSCEIVER

five second delay is completed will return the radio to the Frequency mode and the status
of the Frequency mode prior to entering Channel mode remains the same.

When in Channel mode, pressing the Transfer button will return the radio to Frequency
mode. The channel frequency will become the new USE frequency and the last USE
frequency will become the new STBY frequency. If the radio was in Direct Tune mode (See
Paragraph 3.1.3.E below) prior to entering Channel mode, pressing the Transfer button or
allowing the radio to time out will bring it back to Standby Entry.

C. Program Mode

The Program mode is entered by pressing and holding the CHAN button for longer than two
seconds. The last active frequency remains tuned and displayed in the USE window. The
last used channel number is displayed when Program mode is entered. The channel
number flashes and turning either tuning knob changes the channel number. Pressing the
Transfer button will cause the frequency associated with that channel to flash. The tuning
knobs then work as in the Frequency mode, except that between the rollover points
(118.XXX and 136.XXX) dashes are displayed. These dashes are used to de--program
channels, and to display a channel that is unprogrammed. When the channel frequency is
flashing, pressing the Transfer button will cause the frequency to stop flashing and the
channel number to start flashing at which time a new channel may be selected for
programming.

D. Program Secure Mode

Program Secure mode is used to secure or lock the frequency that is assigned to a channel
so that the frequency assigned to that channel cannot be changed. All channels or
individual channels can be Program Secured. The following list of operations is given to
Program Secure or Un--Program Secure a channel:

To Program Secure a Channel:

1. Hold the CHAN button in for more than 2 seconds (Program mode).

2. Momentarily press the Transfer button (flashing frequency).

3. Change channel frequency to desired Program Secured frequency.

4. Ground the Program Secure pin (TP 501).

5. Momentarily press the Transfer button (Flashing channel number).

6. Unground the Program Secure pin.

To Un--Program Secure a Channel:

1. Hold the CHAN button in for more than 2 seconds (Program mode).

2. Ground the Program Secure pin (TP 501).

3. Momentarily press the Transfer button (flashing frequency).

4. Unground the Program Secure pin.

5. Momentarily press the Transfer button (Flashing channel number)

E. Direct Tune Mode

The Direct Tune mode is entered from the Standby Frequency Entry mode or Channel mode
by pushing the Transfer button for longer than 2 seconds. The tuning knobs operate as in
Standby Frequency Entry, but will change the USE frequency, rather than the STBY
frequency . The radio will be tuned to the Active frequency.

Momentarily pushing the Transfer button returns the radio to Standby Frequency Entry. The
Standby frequency prior to Active Entry mode remains unchanged.

3.1.4 REMOTE FREQUENCY TRANSFER

The Remote Frequency Transfer button operates identically to the front panel Transfer button with
the exception that holding the Remote Transfer button for two seconds does not place the radio in
the Active Entry mode.

3.1.5 REMOTE CHANNEL INCREMENT

Pressing the Remote Channel button will cause the system to enter the Channel mode of operation
and will increment the channel from the previous channel number used.

3.1.7 DISPLAY ADJUST MODE

Press and hold the Channel button, when the unit enters program mode, press and hold the transfer
button for more than 2 seconds so that DA 1 replaces the frequency in the USE window. The unit
is now in display adjust mode, refer to the table below for a description of the 3 DA modes and
ranges of operation. The increment and decrement knobs are used to set the proper value in the
STANDBY window. Momentarily pressing the CHAN button increments the unit thru the 3 display
adjust modes (DA 1 Thru DA 3). Press the transfer button to exit display adjust mode.
