Fma; Buc-Hpa; Kandu; Modman - Honeywell JetWave MCS-8562 Installation And Maintenance Manual

SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
The JetWave™ MCS-8562 Terminal LRUs are as follows:
A.

FMA

- The FMA includes an aperture.
- The FMA contains an LNA for amplification of signals in the receive path.
- The FMA includes the mechanical pointing system, positioner, motors and sensors, and an
IMU to detect movement of the platform.
- The FMA accepts the transmit Ka-band signal from the BUC-HPA.
- The FMA antenna K-band receive path is amplified by the LNA, down-converted and sent to
the BUC-HPA.
- The FMA receives power from the KANDU.
- The FMA accepts the control interface from the KANDU and lets the antenna aperture report
status, BITE, and IMU position back to the KANDU.
B.

BUC-HPA

- Contains a BUC to convert the transmit IF frequencies (950-2000 MHz) to Ka-band frequencies
(29-31 GHz)
- Contains an HPA to increase the signal strength for transmission by the antenna
- Contains an RX L-band interface in which passes through from the FMA to the Modman
- Accepts 115 VAC aircraft power.
C.

KANDU

- Receives commands from the Modman through an Ethernet interface to configure the
antenna/BUC-HPA and reports status over this Ethernet interface.
- Contains the positioning algorithm to allow the pointing of the antenna with inputs from the IRU,
information from the RSSI detector in the Modman, and the IMU from the antenna.
- Provides power and control to the antenna.
- Provides control signals to the BUC-HPA through the RS-422 interface.
- Accepts 115 VAC aircraft power.
D.

Modman

- Is the overall controller of the system.
- Receives and transmits information to the BUC-HPA along the IF frequency between 950-1950
MHz.
- Supplies the user interfaces to the aircraft and passengers as follows:
• The PODD interfaces provide service to the passengers through the use of Ethernet
(10/100/1000 Base T).
• The PIESD interfaces provide services to passenger entertainment devices installed on the
aircraft (in flight entertainment systems). This system uses Ethernet (10/100/1000 Base T).
