1 ABOUT THIS DOCUMENT
The 8730L Series Aircraft Interface Device (AID) provides an interface between various aircraft avionics systems
and nontraditional avionics equipment such as Electronic Flight Bags (EFB), In-Flight Entertainment (IFE)
Systems, broadband communications systems (cellular, Wi-Fi) or onboard network servers; providing both a
hardware and software firewall protecting the critical aircraft systems against any adverse effect from the
interfacing nontraditional equipment.
The AID incorporates a variety of industry standard interfaces; including Ethernet, ARINC 429, ARINC 717, RS-
232, RS-422/485, USB, and Discrete inputs/outputs. The AID also provides a removable mass data storage
device enabling local data storage to hosted applications. An optional embedded cellular or Wi-Fi radio using
remote antennas is available.
The AID incorporates a Linux operating system running on a PowerPC based micro-processor utilizing DDR3
memory. Software supports avionics interface data reception, transmission, concentration, and recording. Access
to this data is provided to locally hosted or remote equipment applications via a built-in ARINC 834 server.

There are five defined model configurations of the AID, each supporting different wireless needs. Model
configuration is accomplished during factory build through the installation radio module internal to the AID
enclosure.
NOTE:
The radios are not accessible and should not be removed by the User.

A SIM card can be installed or removed through the Access Cover on the back of the AID.
The AID has the capability to allow the user to install a CFast card; a solid-state non-volatile data storage device.
The CFast card is a separate LRU (not part of the standard AID configuration) and is accessible through the
Access Cover on the back of the AID for easy removal or insertion. CFast model number 8732D1-1 is available
from UTC Aerospace Systems and has been qualified to operate within the AID operating environment.
NOTE:
The CFast and SIM card are not considered to be hot-pluggable. Ensure the AID is powered off prior to inserting
or removing these devices from the AID.
NOTE:
If the Access Cover on the back of the AID is removed for any reason, reinstall the cover prior to using the AID in
its intended function.
2.2 Mechanical Interfaces
The AID provides mounting provisions (or holes) on the sides of the unit as shown in Figure 1. The 8730L AID is
mounted in the aircraft as a fixed device; it is not movable by the user. The mounting provisions are designed to
interface with a simple U-bracket mounting provision with holes for screws or captive fasteners on the two sides.
Two L-brackets are another potentially simple solution, one on each side.
The AID is cooled by natural convection and by conduction through the mounting provisions. Sufficient clearance
must be provided to permit air flow in the installation. The installation should also be designed to provide a path
for heat to flow through the mounting bracket into the structure.
2.3 Electrical Interfaces
The AID electrical interfaces are made through one 37-pin D-sub pins, (J1), one 37-pin D-sub socket, (J2), and
one 50-pin D-sub pins (J3). The Wi-Fi antenna cable connection and the cellular antenna cable connections are
made with SMA connectors.

The AID provides a chassis ground electrical bonding path through a metal surface contact around its mounting
holes. In addition, the AID bonds its connector shells to local chassis ground and provides a chassis ground pin
in connector J1. One or more of these points should be connected to the aircraft chassis ground through a low
impedance connection path.
2.4 Power Requirements
The AID requires 28 VDC aircraft power as defined in Table 3. Circuit breakers should be chosen based on max
current as shown.

2.5 Wireless Antenna Recommendations
Attached cellular antennas should be Laird part number DBA6927C1-xxxxx. Alternate antennas with similar
performance may be suitable. Gain should not exceed 0.5 dBi at 698-960 MHz and 2.2 dBi at 1710-2700 MHz.
Cellular antennas must be connected through a coaxial cable of at least 20cm length. It is recommended that the
coaxial cable attenuation characteristic is similar or better than Times Microwave Systems Maxgain-200.
Attached Wi-Fi antenna should be Laird part number MAF94271. Alternate antennas with similar performance
may be suitable. Gain should not exceed 2.1 dBi at 2.45 GHz, 2.4 dBi at 4.9 GHz, 2.6 dBi at 5.25 GHz, and 3.4
dBi at 5.875 GHz. The Wi-Fi antenna can be placed directly on the AID, but remote locations through a high
performance coaxial cable may offer improved performance depending on location. Maxgain-200 or better cabling
is recommended.
Guidelines for placement of the antennas:
Antennas should be located in an area with apertures to allow transmission – that is, not a fully enclosed
metal structure.
Maximizing spatial and orthogonal diversity is desired. Locate the antennas not near one another and
rotated 90° relative to one another.
Strive for at least 1 foot away from metal structure.
If a mounting bracket is used to retain the radiating element portion of the antenna(s), it should be non-
metallic and RF-transparent. Avoid carbon based dyes or paint that can hinder RF transmission.
Install antennas in a location where 20 cm is normally maintained between the transmitter’s radiating
structures and the body of nearby persons.

3.2 DO-254 and DO-178C
The AID is developed in accordance with Design Assurance Level E per RTCA/DO-254 and DO-178C.
3.3 Wireless Regulatory Compliance And Industry Certification
The AID has the following regulatory and industry approvals.
3.3.1 FCC
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this
device may not cause harmful interference, and (2) this device must accept any interference received, including
interference that may cause undesired operation.
Consult the SCD 8730L1 for model-specific FCC ID numbers.
3.3.2 Industry Canada
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following
two conditions:
(1) this device may not cause interference, and
(2) this device must accept any interference, including interference that may cause undesired operation of
the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de
licence. L'exploitation est autorisée aux deux conditions suivantes :
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est
susceptible d'en compromettre le fonctionnement.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and
maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference
to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power
(e.i.r.p.) is not more than that necessary for successful communication.
Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une
antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but
de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type
d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité
nécessaire à l'établissement d'une communication satisfaisante.
Consult the SCD 8730L1 for model-specific IC ID numbers.
