1.2EQUIPMENT 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.
The KXP 2290 will work with any conventional ATCRBS blade or quarter-wave monopole type antenna provided it is certified to TSO-C112/ETSO-2C112a A representative type is the Honeywell
KA 61 antenna, P/N 071-00221-0010 (BNC) or 071-00221-0020 (TNC). Refer to FIGURE 2-4 KA
61 INSTALLATION DRAWING for KA 61 technical characteristics, installation, and certification
information.
RTCA/DO-178B SOFTWARE LEVEL “B”
SEE ENVIRONMENTAL QUALIFICATIONS APPENDIX
NOTE:
Two antennas (top and bottom) are required for diversity operation.
P/N 066-01198-0101 is the only version of the KXP 2290 that is currently available.

2.3.2KXP 2290 INTERCONNECTION AND CABLE HARNESS FABRICATION
2.3.2.1General
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.
(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.
