3.4.2 Power Wires
Audio International recommends the chassis be electrically bonded
to the airframe structure by a conductive mounting point with <0.1
Ω
resistance using <50
Ω
impedance cable. Aluminum wool, nylon
webbing impregnated with aluminum oxide abrasive or fiber bristle
brushes are the approved tools for removing anodized surfaces at
mounting point where the bonding wire is attached. Power and
Ground wires shall be in accordance with
MIL-W-22759
or
equivalent. Protect power wires with circuit breakers or fuses
located close to the electrical power source bus.
3.4.3 Interconnect Wiring
3.4.3.1 Use shielded category 5 (CAT 5) cable for all Ethernet
connections. Use PIC wire and cable 10/100Base-T
quad (4-conductor) cable or equivalent. (PIC P/N:
E10424).
3.4.3.2 Use Stewart Connector RJ-45 plug or equivalent for all
Ethernet connection aircraft harness terminations
interfacing. (Stewart Connector P/N: 943-SP-37-08-S).
3.5 Physical Characteristics
3.5.1 Refer to Section 5.0 for unit dimensions.
3.5.2 Refer to Section 6.0 for attachment points.
3.5.3 When mounting the unit, allow sufficient space for mating
connectors.
3.6 Electrical Characteristics
3.6.1 Electrical Specifications:
Electrical
Operating Range
+18 to +32 VDC
1 A at +28 VDC (Nom)
Power Consumption
2 A at +28 VDC (Max)
3.6.2 Ethernet specifications limit the cable length between the PC or
server and the switch to 328 feet (100 meters).
