RF-7800I Vehicular Intercom System - Harris RF Communications ...

RF-7800I Vehicular Intercom System

The RF-7800I Vehicular Intercom System is the customizable, reliable
choice for intercom communications – any vehicle, any mission.
The RF-7800I is a comprehensive solution for in-vehicle voice and
data communication, tactical network connectivity, and battle
management system interoperability. The RF-7800I provides voice
and data connectivity among vehicle crew members while creating
a network backbone to integrate vehicle communication systems.
With a modular, configurable platform, the RF-7800I is not only
easy to install, but is also lightweight and power efficient.
Designed to MIL-STD-810F specifications, the rugged RF-7800I
interoperates with the family of Harris Falcon ® tactical radios
as well as other military, government and commercial devices.
This allows crew members to communicate with dismounted
personnel and other vehicles or command centers through
HF, VHF, UHF, SPR and BGAN satellite communications technology.

A Highly Customizable System.
The RF-7800I provides integrated, all-in-one support for data and Ethernet
connectivity while its advanced speech recognition and noise elimination
technology provide clear voice transmission in noisy environments.

RF-7800I-CU
Central Unit
The Heart of the RF-7800I Intercom System
The intercom system’s main component, the Central Unit, performs voice channel
switching and digital data packet routing between 8 Crew Stations and 4 combat
net radios. The Central Unit also has 2 general purpose serial ports, 2 serial/USB
host ports, a Speaker Unit port, and 2 Ethernet ports for full network integration.
A “light” version is available for voice-only applications with support for 4 Crew
Stations and 2 radio transceivers.
The Central Unit provides clear voice communications using digital signal processing
technology that eliminates vehicle background noise for maximum voice intelligibility
for all crew members. In addition, the Central Unit monitors vehicle system status,
Crew Stations controls, and Crew Stations indicators.
The Central Unit, Crew Stations, and additional components are all software
configurable and upgradable through a simple, PC based user interface. This
application allows for the easy incorporation of feature enhancements and
reconfiguration of the system to support new mission requirements.
Modular Components and Simple Cabling for Easy Installation.
The compact, modular design integrates seamlessly with a variety of combat net
radios including Harris Falcon ® products and is extensible to BMS and situational
awareness applications.
The communication between the Central Unit and the Crew Stations is established
over a single, easy to install four-wire interface. This interface provides power to
the Crew Stations and ANR headsets, programming and real time configuration
capabilities. In addition, it provides duplex streams of 64 kbps digitized PCM voice
channels, and duplex streams of digital synchronous communication with data and
control signals of the serial asynchronous ports.

Crew Station Components

The RF-7800I offers three types of Crew Stations, each with
distinct user-interface capabilities and features:
Keypad Display Unit Rotary Dial Unit Basic Unit
The Central Unit interfaces to any combination of Crew Stations to provide custom solutions for any vehicle
or command center application. Crew Stations allow operators to monitor selected channels, conference
with selected intercom users, monitor and transmit via radio transceivers, and access external connections
such as telephone lines. Each Crew Station comes in two variants: dual headset or a single headset and a
data port to support a PC or other data device.

Intuitive User Interface and Flexible Functionality.
The Keypad Display Unit is software configurable to
accommodate the needs of the specific users including
the function and position of the icons.
RF-7800I-KD
Keypad Display Unit
The fully featured Keypad Display Unit provides real-time command and control of the
intercom and radios for maximum mission flexibility. This Crew Station offers a high resolution
OLED screen for displaying options, messages, and commands. The keypad drives the icons on
the display allowing the user access to the intercom and radio channels with a simple, single
key press. When selecting different options, operators receive audible feedback in their native
language as configured through the central unit programming software.
Harris Falcon radio users can take advantage of the Keypad Display Unit to remotely control
radio parameters. Users are able to navigate through presets, issue calls to radio network users,
display GPS information, and control power configuration.

RF-7800I-RD
Rotary Dial Unit
The Rotary Dial Unit provides operators with real-time selection of
16 pre-programmed modes of operation through a single turn of a knob.
Users can easily determine the Crew Stations or radio assets that are in
use by the status indicators provided at each dial position.
Second Nature Operation.
The Rotary Dial Unit allows the user to focus on the mission
and leverage the preprogrammed intercom system to streamline
communication. Switching into the appropriate position to
communicate with the team, make a phone call, or respond to
an alarm becomes second nature with just the turn of a knob.

RF-7800I-BU
Basic Unit
The Basic Unit provides operators with pre-programmed modes
of operation through a hands free plug-and-play interface. It is an
ideal solution for crew members who require voice and data
communications.
Easy, Hands-Free Operation.
The Basic Unit is preconfigured for voice and data communications
and is ideal for executing time sensitive, critical operations. With the
preprogrammed unit, the user can communicate any urgent message
quickly and reliably.

Additional Components
RF-7800I-SA
Speaker Unit
The Speaker Unit features an 8-watt amplifier
and a 6-step volume control knob. Its highpower
is ideal for command broadcasts or radio
monitoring. The system can be preconfigured to
simultaneously monitor any or all of the audio
sources connected to the intercom via
the speaker.

RF-7800I-TA
Telephone & Alarm Unit
The Telephone & Alarm Unit provides seamless
integration with an analog PBX or a field telephone
to enable direct dialing from the Crew Stations.
One unit can connect a PBX and field phone at the
same time to support incoming and outgoing calls.
The unit includes an alarm/sensor interface for monitoring
warning signals originated by vehicle subsystems
such as engine, NBC and IR warnings. Events trigger a
warning voice broadcast relevant to the alarm source
while flashing the Crew Station’s red button.
The Telephone & Alarm Unit
is configurable to detect the
following signals:
• GND/ not connected
• 24V/ not connected
• GND/ 24V
