1.0 INTRODUCTION

1.1

General

This installation manual (800-10680) provides the required instructions to install the AirCell

Satellite

Transceiver (ST) 3100 system (AirCell

ST 3100). This system allows for two-way communications from

the aircraft, including voice or PC (via the Iridium on-board modem). These services are available when
the aircraft is in the air or on the ground. On the ground or in the air, the satellite communications link is
provided using the Iridium LEO (Low Earth Orbit—485 miles altitude) array of 66 satellites that enable
total earth coverage.

An Iridium-approved antenna is mounted on the top of the aircraft to provide the Radio Frequency (RF)
interface for the aircraft to satellite connection. The AirCell

ST 3100 system provides options for multiple

handsets. The AirCell

ST 3100 provides three (3) handset voice channels and a single Audio Panel

interface. Optimal handset performance is realized when handsets are wired directly to a dedicated voice
channel. When required, two handsets can be wired in parallel to a single voice channel. However,
audio quality during conferencing (intercom) between handsets deteriorates when wired in this manner. If
conferencing (intercom) is required, it is best to use a separate voice channel for each handset. The
Satellite Transceiver also has an on-board modem that accepts RS-232 serial data from a Personal
Computer, Cabin Entertainment Systems and Multi-Function Display systems.

Note

ST 3100 part number 400-01680-001 has a Plain Old Telephone System (POTS) interface and the 400-
10680-002 has no POTS interface. These transceivers are identical including revision levels; the only
exception is the -002 configuration lacks a POTS module installed on the motherboard.

The ST 3100 System was tested for Operational Shock and Crash Safety to DO-160D, Section 7,
Category B. Radiated RF Interference met the conditions of DO-160D, Section 21, Category M.
Equipment Specifications are found in Section 7.0. Install the AirCell

ST 3100

Transceiver in locations

that are free of water, spray, or other fluids, whether by direct contact or condensation. When installing
the AirCell

ST 3100 system in the aircraft, carefully follow this Installation Manual.

The AirCell

ST 3100 system meets environmental requirements identified in RTCA DO-160D, as defined

in Section 4, Category F2. Any alteration of this product voids the federal Aviation Administration (FAA)
or Federal Communications Commission (FCC) certification and the AirCell

warranty. This publication is

not to be used in lieu of a Supplementary Type Certificate (STC) or any other FAA approval. FAA form
337 approval is usually required for installation of this equipment.
