SYSTEM DESCRIPTION AND INSTALLATION MANUAL
JetWave™ System
© Honeywell International Inc. Do not copy without express permission of Honeywell.
NOTE: Input signal range: -79 to -5 dBm. Output signal range -30 to +5 dBm. Incross talk
requirement: -25 dBc. Output cross talk requirement: -40 dBc.
B. APM
The APM can be installed in any orientation. Refer to F
igure 4-24 for outline and installation
information and Figure 4-34 thru Figure 4-37 for the applicable interconnect diagram.
There are no special tools, fixtures, and equipment required for the APM installation.
There are no clearance requirements for the APM.
Use 0.164-32 UNC-2A corrosion resistant mounting fasteners. Do not exceed 25 in-lb (2.8 Nm) or
minimum ultimate tensile strength of 125 KSI (861.845 newton/millimeter²) when you torque the
screws.
APM to Modman interconnect cable must use ARINC 664 compliant 2 shielded twisted pair 24
AWG (or aerospace grade shielded Cat 5/Cat 5E minimum) PN ECS 922404 or equivalent, with a
maximum length of 9.8 feet (3 m).
The APM must be electrically bonded to the airframe through contact with the base of the unit or
through a bonding cable attached to M3 earth stud. The APM bonding resistance must be less than
or equal to 2.5 mΩ.
C. Maintenance Panel
If the JetWave™ system is not wired to other systems on the airc
raft, the discrete I/O and Ethernet
ports must be brought out to a suitable maintenance panel to allow for system checks and routine
maintenance, such as system software upgrades. The discrete I/O and Ethernet ports needed are
as follows:
(1) Discrete Outputs:
NOTE: Discrete outputs are normally open and capable of sinking 20 mA of current with a
maximum voltage of 36 VDC as per ARINC 763.
• System available (Modman MP13E) open/ ground output connected to a lamp
