SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
(3) Tx Waveguide and Rx Coax Interconnection between the FMA and the BUC-HPA. These
interconnections can either be customer designed and furnished, or purchased from
Honeywell. For Honeywell interconnections, installation details are as follows:
(a)
(4) Connecting the FMA Interface, BUC-HPA Power, and Control Interfaces
The control signals for the BUC-HPA are supplied from the KANDU and are connected to
BUC-HPA J2 receptacle.
FMA signal ground is the reference ground for communication between FMA and KANDU,
refer to Figure 3-12 for installation details.
The 115 VAC power supply for the BUC-HPA is supplied from the aircraft power and is
connected to BUC-HPA J1 receptacle.
The IF TX and IF RX signals to BUC-HPA are supplied from the Modman. These signals
are routed through the bulkhead interface. Refer to the FMA interconnection diagram
Figure 3-12 for details.

For installation design requirements and instructions associated with the waveguide
and coax cable in between the FMA and the BUC-HPA (RF Kit P/N 90409025-02),
refer to the following documents:
1 Tx Waveguide options available from Honeywell
a For the 90404802 Pass 4.0 Tx Waveguide (included in RF Kit
P/N 90409025-02), refer to Honeywell drawings 90404969 (Pass
4.0 Waveguide Outline and Installation) and 90410128 (WR34 to
WR28 JetWave waveguide kit).
2 Rx Coax
a For the 90410125-02 RX Coax Cable Assy (included in RF Kit
P/N 90409025-02), refer to Honeywell drawing 90410125
(JetWave 2.0 BUC-HPA to FMA IF RX cable assy).
b When attaching the Rx coax cable to the FMA 2.92mm coax
connector, torque the connector nut to between 7.0 in·lb and 10.0
in·lb (0.8 Nm to 1.1 Nm) using a calibrated torque wrench.
c When attaching the Rx coax cable to the BUC-HPA TNC
connector, torque the connector nut to between 12.5 in·lb and
14.5 in·lb (1.4 Nm to 1.6 Nm) using a calibrated torque wrench.
Remove the protective covers from the FMA P2 and KANDU J2 receptacles.
Visually examine the connectors and make sure that the pins are straight and
undamaged.
1 Clean the connectors with the contact cleaner and connect the cable
assembly for fuselage mount from the KANDU J2 receptacle to the FMA
P1, P2, and P3 receptacles.
2 Make sure that the over braid of the cable assembly is terminated to
connectors at both the FMA and KANDU ends.
