GENERAL INFORMATION

1.1 INTRODUCTION

This manual contains information relative to the physical, mechanical, and electrical characteris­tics of the Honeywell KXP 2290 Mode S Transponder. Installation and check out procedures are
also included. Information relative to the maintenance, alignment, and procurement of the re­placement parts may be found in the KXP 2290 Maintenance/Overhaul Manual, P/N 006-15689­XXXX. The only current KXP 2290 installation option is as a part of the APEX system. The KXP
2290 is blind-mounted and shares a mounting rack with the KMC 2210 APEX controller. For ad­ditional information relating to the APEX system, refer to the APEX System Manual 006-10667­XXXX.

1.2 EQUIPMENT DESCRIPTION

The KXP 2290 is a Mode S Transponder that is capable of non-diversity or diversity operation.
The KXP 2290 Mode S Transponder is designed to meet TSO-C112, ETSO-2C112a for a Class
2A ATCRBS/Mode Select Airborne Transponder System. It replies to ATCRBS Mode A and C,
Intermode, and Mode S interrogations.

Since the KXP 2290 is a Class 2A transponder, it can handle Comm A & Comm B Mode S data
link protocols. The KXP 2290 is compliant with TSO-C112 Class 2A and ETSO-2C112a require­ments. The EUROCAE ED-73B transponder functionality is Level 2 (Surveillance and Comm A/
B) and the marking is level 2s. Additionally the ED-73B defined class is "CLASS 1". The KXP
2290 is also designed to meet the Enhanced Surveillance mandated in Europe.

The KXP 2290 has the ability to receive an 8-digit alphanumeric Flight ID code. The flight crew
enters the Flight ID information via the APEX control panel.

The KXP 2290 uses ARINC 735A TCAS interface protocol to interface with TCAS II. As a periph­eral to the TCAS II processor, the transponder receives and replies to short and long Air-to-Air
surveillance and TCAS Coordination interrogations. Also, it receives and replies to Ground-to-Air
surveillance and Comm-A interrogations directed to TCAS.

Top and bottom antennas provide the diversity option that allow compatibility with TCAS. The di­versity option allows selection of signal receptions from either the top or the bottom antenna based
on the characteristics of the received interrogation signals. This improves air-to-air surveillance
and communication. An Optional top-mounted omnidirectional antenna is required for diversity.

The KXP 2290 contains BITE (Built In Test Equipment) so the operational health of the unit is con­stantly monitored. When a critical fault is detected, the unit will notify the APEX system. The unit
stores detected failures in non-volatile memory for later review. The unit also has a temperature
sensor and a timer so that faults can be time stamped and temperature data can be collected and
stored.

n KXP 2290

The installation should be installed in accordance with standards established by the customer’s
installing agency and existing conditions as to unit location and type of installation. However, the
following suggestions should be considered before installing the system. Close adherence to
these suggestions will assure a more satisfactory performance from the equipment.

The installing agency will supply and fabricate all external cables. The connectors required are
supplied by Honeywell.

NOTE:
The TSO identifies the minimum performance stan­dards, tests, and other conditions applicable for issu­ance of design and production approval of the arti­cle. The TSO applicant is responsible for document­ing all limitations and conditions suitable for installa­tion of the article. An applicant requesting approval
for installation of the article within a specific type or
class of product is responsible for determining envi­ronmental and functional compatibility.

2.3.2 KXP 2290 INTERCONNECTION AND CABLE HARNESS FABRICATION

2.3.2.1 General

The KXP 2290 Mode S Transponder receives primary power from the aircraft power source. Pow­er connections, voltage requirements, and circuit breaker requirements are shown on the inter­connect diagrams (FIGURE 2-5 KXP 2290 INTERCONNECTION DRAWING).

The length of the wires to parallel pins should be approximately the same length, so that the best
distribution of current can be effected. Honeywell recommends that all wires, including spares as
shown on the interconnect diagram be included in the fabrication of the wiring harness. However;
if full wiring is not desired, the installer should ensure that the minimum wiring requirements for
the features and functions to be used have been incorporated.

When cables are installed in the aircraft, they must be supported firmly enough to prevent move­ment and should be carefully protected against chaffing. Additional protection should also be pro­vided in all locations where the cable may be subjected to abuse.

In wire bundles, the cabling should not be tied tightly together as this tends to increase the possi­bility of noise pickup and similar interference. When routing cables through the aircraft the cables
should cross high level rf lines at right angles.

Prior to installing any equipment, make a continuity check of all wires and cables associated with
the system. Then apply power and check for proper voltages at system connectors, and then re­move power before completing the installation.

Please note the following guidelines:

(1) The installing facility will supply and fabricate all external cables. The required con-

nectors are supplied as part of the installation kit (P/N 050-03451-0000).

(2) The KXP 2290 must be kept a minimum of three feet from the antenna(s). Addition-

ally, the antenna coax cable(s) should not be bundled with the other wiring harness­es to the KXP 2290.

Rev. 0c, June/2006 Preliminary 05/24/06 10689I00.JA Page 2-2

n KXP 2290

(3) The length and routing of the external cables must be carefully planned before at-

tempting the actual installation. Avoid sharp bends or locating the cable near aircraft
control cables. The cables should be of a length to allow for a “maintenance loop”.
That is, the length should be adequate to access and extend the connectors aft of
the panel for future maintenance purposes. Excess cabling should be secured and
stowed by tie-wrapping until such maintenance is required.

(4) The cables should be supported firmly enough to prevent movement. They should

be carefully protected wherever one may chafe against another or against some oth­er object. Extra protection should be provided in all locations where the cables may
be subject to abuse. Shields on shielded wires should be grounded as shown on
the system interconnection diagrams.

(5) Shields should be carried through any obstruction via a thru-bulkhead connector. If

shielding cannot be carried through by use of a bulkhead/connector pin, precautions
should be taken to ensure each segment of the shielded lead be grounded at only
one point. A ground connection of not more than two inches in length should be
used. The preceding discussion does not apply to coaxial and quadraxial cable.

(6) Avoid routing cabling near high noise and high power sources.

(7) Do not route the transponder antenna coax(s) near ADF sense or loop antenna ca-

bles.

(8) Antenna Transmission Line Loss Considerations

NOTE:
The total losses in the coaxial cable run and inter­connects between the antenna(s) and the KXP 2290
transponder must not be less than 0.5 dB and must
not be more than 2.0 dB at 1030MHz.

NOTE:
The antenna cabling information noted in this sec­tion, in particular by FIGURE 2-8 RG-400 CABLE

CONNECTIONS DRAWING, FIGURE 2-9 ECS/
ECS-RG-400 CABLE CONNECTIONS DRAWING,
FIGURE 2-10 CABLE CONNECTOR DRAWING,
FIGURE 2-11 TYPE “N” AND “C” CONNECTOR AS­SEMBLY DRAWING, and FIGURE 2-12 BNC CON­NECTOR ASSEMBLY DRAWING, is provided as

possible antenna connection solutions and is provid­ed for reference only. While the options noted in the
figures will be applicable to many installations, ad­herence to the following sub-sections will ensure that
the total cable/interconnection losses are within
specification.

Rev. 0c, June/2006 Preliminary 05/24/06 10689I00.JA Page 2-3

n KXP 2290

(a) Consult manufacturer’s coaxial cable data sheet specifications. Using the

length of the top and/or bottom antenna cables and the manufacturer speci­fied dB loss per foot of cable type, select a particular type or types of cable
that meet the top and bottom cable loss limitations. In anticipation of aging
factors, it is advisable to select a cable type that has an insertion loss that
when combined with interconnect losses will equal a dB loss significantly low­er than 2 dB.

(b) In diversity installations, it is conceivable that the type of cable selected to

meet the dB loss requirements of the top antenna cable will be different than
the type of cable selection required to meet the dB loss requirements of the
bottom antenna. For example: if the antenna run to one antenna is relatively
lengthy, and the antenna run to the other antenna is relatively short, the longer
run may require low loss antenna cable to meet the less than 2 dB antenna
cable/interconnect requirement while the short run may require a relatively
higher loss cable to exceed the 0.5 dB antenna cable/interconnect loss re­quirement

NOTE:
For installations with diversity transponder antennas
(top and bottom) the cable lengths must be within 10
feet of each other.

(c) Consult manufacturer’s data sheets to determine the nanosecond delay per

foot (at 1030 MHz) for the type or types of cable selected.

2.3.2.2 Primary Power and Circuit Breaker Requirements and Wiring

The KXP 2290 transponder receives primary power from the aircraft power circuit breakers. The
KXP 2290 is designed to operate over the range of 18-32V dc. Power connections, wire sizes,
and circuit breaker requirements are shown on the interconnection diagrams FIGURE 2-5 KXP

2290 INTERCONNECTION DRAWING.

2.3.3 EQUIPMENT LOCATION

Care should be exercised to avoid mounting components near equipment operating with high
pulse current or high power outputs such as radar and satellite communications equipment. In
general, the equipment should be installed in a location convenient for operation, inspection, and
maintenance, and in an area consistent with the TSO environmental limits.

Refer to the mechanical installation drawing (FIGURE 2-2 KXP 2290 INSTALLATION DRAWING),
cable and connector assembly diagrams (FIGURE 2-7 RF CONNECTOR DRAWING, FIGURE 2-

8 RG-400 CABLE CONNECTIONS DRAWING, FIGURE 2-9 ECS/ECS-RG-400 CABLE CON­NECTIONS DRAWING, FIGURE 2-10 CABLE CONNECTOR DRAWING, FIGURE 2-11 TYPE

DRAWING), and connector pin assignments diagrams (FIGURE 2-1 MAIN CONNECTOR ­JKXP2290-1, TABLE 2-2 JKXP2290-1 PIN FUNCTION LIST) as required. Determine the mount-

ing location for system components following the guidelines below.

2.3.3.1 Transponder And Mounting Tray Locations

The KXP 2290 Mode S Transponder shares a mounting tray with the Honeywell APEX KMC 2210
controller and is part of the APEX cockpit panel configuration.

Except for antenna cables the lengths of the cables from the KXP 2290 transponder mounting tray
connector to other system units are not critical because unit interfaces are designed with high im­pedance inputs, low impedance outputs, and low noise susceptibility characteristics.

2.3.3.2 Antenna(s)

The antenna(s) should be well removed from other antenna 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(s). The surface directly beneath the antenna(s)
should be a flat plane over as large an area as possible.

A back-up plate for each antenna should be used for added strength on thin-skinned aircraft.
The antenna(s) need to be within 5 degrees of the centerline
To prevent rf interference, the antenna(s) must be physically mounted a minimum distance of

three feet from the KXP 2290 and the wiring harness.
The transponder antenna(s) should be mounted a minimum of 30 inches away from the TCAS or

DME antennas and four feet from the ADF sense antenna.
Where practical, plan the antenna location(s) to keep cable lengths as short as possible and avoid

sharp bends in the cable to minimize the VSWR.
Avoid running other cables or wires near the antenna cable(s).
On pressurized aircraft, the antenna(s) should be sealed using an approved sealant, such as RTV

No. 3145 (P/N 016-01082-0000) or equivalent, around the connector and mounting hardware.
The antenna mounting(s) should be sealed from the outside for moisture protection using RTV or

equivalent.
Mount the antenna(s) in as clean as environment as possible, away from exhaust gases and oils.

The antenna(s) should be kept clean. If left dirty (oil covered), the range of the transponder may
be affected.

For installations with diversity transponder antennas (top and bottom) the distance between the
top and bottom antennas on the horizontal plane of the aircraft fuselage must not exceed 25 feet
(7.62m).

2.3.4 KXP 2290 INSTALLATION

2.3.4.1 General

The mounting tray for the transponder/control unit should be mounted using the dimensions spec­ified in the outline and mounting drawing, FIGURE 2-2 KXP 2290 INSTALLATION DRAWING.
KXP 2290 wiring should be per the system interconnect diagram, FIGURE 2-5 KXP 2290 INTER-

CONNECTION DRAWING.

2.3.4.2 Transponder

(1) Slide the transponder into the tray until the front lobe touches the mounting tray.

(2) Turn the Allen wrench clockwise until the rear lobe engages the mounting tray slot.

Continue turning the wrench clockwise until tight.

CAUTION:

DO NOT OVERTIGHTEN THE LOCKING FASTENER

2.4 POST-INSTALLATION CHECKS

2.4.1 TRANSPONDER SYSTEM CHECKOUT

The post-installation test is used to apply power and functionally checkout the system. Successful
completion of the post-installation test verifies the proper operation of the KXP 2290 Mode S Tran­sponder System.

TABLE 2-4 INSPECTION/CHECK PROCEDURE is a visual inspection/check procedure that

should be performed after system installation as part of a system checkout. A post-installation test
per paragraph 2.4.1.2 Post-Installation Checkout/Operation should be performed. In addition, the
procedure should be used as a periodic maintenance inspection check.

EQUIPMENT INSPECTION/CHECK PROCEDURE

KXP 2290 Mode S A. Inspect external surface for damage.

Transponder

Antennas A. Inspect external surfaces for damage.

2.4.1.1 Inspection

Perform the following inspection on the overall system:

(1) Check that cables do not interfere with aircraft controls or other equipment.

(2) Check cabling for proper routing and check security of tie-down points. Inspect and

adjust cable runs to ensure that cables are not strained, kinked, or severely twisted
and are not exposed to rough or sharp surfaces.

B. Check that the unit is securely installed and that retaining
mechanism is securely tightened.

C. Ensure that all connections in the mounting tray are properly
mounted and secure.

B. Check that antenna is properly mounted and mounting screws
are tight.

C. Ensure that antenna coaxial cable connectors are properly mated
and secure.

TABLE 2-4 INSPECTION/CHECK PROCEDURE

2.4.1.2 Post-Installation Checkout/Operation

(1) General

Installation of the transponder system requires three stages of testing to ensure the
proper operation of the Mode S transponder. Initially, prior to the installation of the
transponder and antenna, a system interwiring check should be performed. This
check verifies that the aircraft and all transponder interconnections are correct, be­fore power is applied. After the units are installed a visual inspection of the equip­ment and connections is made. Finally, a post-Installation test is performed.

Rev. 0c, June/2006 Preliminary 05/24/06 10689I00.JA Page 2-37

n KXP 2290

(2) System Interwiring Check

To check the aircraft and transponder system interconnections proceed as follows:

(a) Check that all cables and interwiring are installed in accordance with the In-

terwiring and Cable Harness Fabrication instructions (paragraph 2.3.2 KXP

2290 INTERCONNECTION AND CABLE HARNESS FABRICATION).

(b) Using the interconnect diagram (see FIGURE 2-5 KXP 2290 INTERCON-

NECTION DRAWING), check wiring for proper destination, opens, and

shorts.

(c) Check rf cables for insertion loss and VSWR.

(3) Visual Inspection

In conjunction with system installation, perform the inspection/check procedure (TA-

BLE 2-4 INSPECTION/CHECK PROCEDURE).

(4) Post-Installation Test

Perform the ATC transponder tests and inspections noted in section 1.7.1 EQUIP-

MENT (per Federal Aviation Regulation Part 43).
