Honeywell JetWave MCS-8562 Installation And Maintenance Manual page 64

SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
A. KANDU to FMA bulkhead interconnect specification is as follows:
(1) Power and control signals required for the JetWave™ MCS-8562 Terminal LRUs installed
outside the aircraft will be routed through the power and control bulkhead interface
connectors which will be sealed to maintain cabin pressure (max 14.5 PSI (1,000 hPa))
inside the cabin.
(2) Maximum round trip wiring interconnection resistance between KANDU A3J2 and
OAE-FMA- A5P1 must not exceed 0.326 ohms (considering the 16 AWG wire cables of
length 32.8 feet (10 m)).
(3) It is recommended to use hermetically sealed MIL-DTL-38999 series III, insert 19-35,
normal keying with 66 contacts as KANDU bulkhead control connector for KANDU
interwiring to the OAE-FMA. To be labeled as BI-control.
(4) It is recommended to use hermetically sealed MIL-DTL-38999 series III, insert 17-8, normal
keying with eight contacts as KANDU bulkhead power connector. To be labeled as
BI-power.
(5) It is recommended to use TNC/N-Type hermetically sealed bulkhead interface in accordance
with MIL-STD-348 for the routing of the TX-IF signals between the Modman and BUC-HPA.
The TX-IF interface to be labeled blue.
(6) It is recommended to use TNC hermetically sealed bulkhead interface in accordance with
MIL-STD-348 for the routing of the RX-IF signals between the Modman and BUC-HPA.
The RX-IF interface to be labeled green.
(7) KANDU receptacle A3J4 is TVP00RGQF-21-75P (Amphenol) or equivalent. Mates with
TV06RQF-21-75S (Amphenol) or equivalent for Ethernet interface.
(8) The following bulkhead connector design principles are recommended:
(a)
(b)
(c)
(9) It is recommended that the bulkhead interface be installed such that receptacle pins are
on the pressurized area and receptacle sockets are on the unpressurized side of the
aircraft.
(10) The bulkhead interface connectors must be electrically bonded to the aircraft.
B. The KANDU must be electrically bonded to the airframe through contact with the base of the unit
as follows:
- At least one of the two provided mechanical attachment points for electrical bonding must be
used for bonding the KANDU to the airframe. Make sure that the all mating surfaces in the
bonding path are free from contaminants such as paints or other non-conductive elements.
- One 0.65 inch (16.5 mm) diameter circular and one 0.65 inch (16.5 mm) diameter by 1.02 inch
(25.9 mm) diameter elongated conductive area is provided around two of the mounting holes
of the equipment base plate.
- The KANDU includes a 0.59 inch (15 mm) diameter bonding measuring point on one of the
attachment tabs, close to the bonding element, but not on the bonding element.
