Apm; Maintenance Panel - Honeywell JetWave MCS-8562 Installation And Maintenance Manual

SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
C.

APM

The APM can be installed in any orientation. Refer to Figure 3-8 for outline and installation
information and Figure 3-12 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. Do not exceed 4.1 in-lb plus an allowance for
the lock mechanism used. The APM bonding resistance must be less than or equal to 2.5 mΩ.

Maintenance Panel

If the JetWave™ MCS-8562 Terminal is not wired to other systems on the aircraft, 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:

JetWave™ MCS-8562 Terminal
Discrete outputs are normally open and capable of sinking 20 mA of current
with a maximum voltage of 36 VDC as per ARINC 763.
Optional: System available (Modman MP13E) open/ ground output connected to a
lamp
Optional: Data link available (Modman MP13F) open/ ground output connected to a
lamp.
Mandatory: Local data load enable (Modman MP10B) connected to a normally open
switch with a GND to enable
Mandatory: Ground transmit. Ground transmit enable may be hard-wired for the desired
behavior at the Modman connector (Modman MP11D) connected to a normally open
switch with a GND to enable.
Optional: Public service disable (Modman MP11E) connected to a normally open switch
with a GND to enable
Optional: Modman reset (Modman MP10C) connected to a normally open switch with
a GND to enable
Optional: External Modem Enable (Modman MP11C) open/ground to switch between
internal and external modem mode
Optional: Weight-on-Wheels (Modman MP11A) connected to determine Air/Ground
Status, as configured by the AES system configuration data.
