This document and the information contained herein (“the Materials”) are the proprietary data of Honeywell.
These Materials are provided for the exclusive use of Honeywell-authorized Service Centers;
Honeywell-authorized repair facilities; owners of a Honeywell aerospace product that is the subject of these
Materials (“Honeywell Product”) that have entered into a written a greement with Honeywell relating to the repair
or maintenance of Honeywell Product; and direct recipients of Materials from Honeywell via
https://myaerospace.honeywell.com/wps/portal/ that own a Honeywell Product. The terms and conditions of this
Honeywell Materials License Agreement (“License Agreement”) govern your use of these Materials, except to
the extent that any terms and conditions of another applicable agreement with Honeywell regarding the
maintenance or repair of a Honeywell Product and that is the subject of the Materials conflict with the terms and
conditions of this License Agreement, in which case the terms and conditions of the other agreement will govern.
However, this License Agreement will govern in the event of a conflict between these terms and conditions and
those of a purchase order or acknowledgement. Your access or use of the Materials represents your acceptance

1.1 INTRODUCTION
This manual contains information relative to the physical, mechanical, and electrical characteristics of the
Honeywell KTR 2280A MMDR. Installation and check out procedures are also included. Information relative to
the maintenance, alignment, and procurement of the replacement parts may b e found in this KTR 2280 A CMM,
Publication No. D201610000050. Final design of the installation an d ai rwor th iness approval is incumbent upo n
the installer and their respective certification authority.
1.2 EQUIPMENT DESCRIPTION
The KTR 2280A MMDR T ransceiver is a blind panel mounted integrated transceiver containing one transmitter
and six receivers. Depending on system configuration, all six receivers can be simultan eously active. The KTR
2280A will operate from a normal voltaqe of 27.5 VDC. The KTR 2280A is designed with ARINC 429 interfaces
which is intended for use in the aircraft. It is also designed with RS-422 capabilities that will be used primarily
for development and testing in the engineering lab. The KTR 2280A is controlled by other LRUs which will
send control information to the KTR 2280A th rough ARINC 429 data. Some outputs from the KTR 2280A are in
digital formats and sent to other LRUs through ARINC 429. Other outputs are more traditional analog outputs.
The six receivers and their modes of operation are as follows, The NAV receiver operates in one of three
modes as dynamically controlled by the system interface. These three modes are VOR, LOC, and VDB. The
GS operates in the Glideslope mode only. The ADF operates in the di rection find ing an d AM modes. There are
three COM receivers. The first COM is a traditional AM mode receiver with either 25 or 8.33 kHz channel spac
ing. The second AM COM receiver functions as a Guard channel receiver with either 25 or 8.33 kHz channel
spacing. The third COM receiver is capable of receiving either VDL Mode 2 (D8PSK) or VDL Mode A (MSK)
signals. The COM transmitter is capable of AM, VDL Mode 2, or VDL Mode A modes.
The KTR 2280A contains BIT equipment so that the operatio nal health of the unit is constantly monitored. When
a critical fault is detected, the unit notifies the host 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.
