1.3 General Description

1.3.1 Mechanical Description

The IC6100 IC Amplifier Unit is designed for installation in the avionics compartment of an aircraft.
The IC6100 IC Amplifier Unit is a device in standard ¼ ATR short case.

Two unit connectors are fitted on the front and two unit connectors on the back side. The IC Amplifier Unit consists
of the following circuit boards:

• Dual-Headset Amplifier Board (max. 3 ea.),

• Analog Board,

• DSP Board,

• CPU Board,

• Bus Board,

• Connector Board.

1.3.2 Electrical Description

The IC6100 IC Amplifier Unit is an Intercom System, software configurable and accordingly influences and
processes all incoming and outgoing audio signals from the headsets and from IC Ring, performs the logical
functions necessary for aircraft intercommunication and provides the creation of up to 2 IC Ring groups which
can communicate together or isolated at will, by using the Alert Tone activation Line #2. Also allows the
generation of up to 8 different aural tone signals which may be activated through discrete control lines, which can
be used as HOT MIKE lines (up to 6 as Hot mike) or Alert Tone activation lines (alert tones from 3 to 8) and 2 as
Alert Tone activation lines or one as alert tone (#1) and the other as ISOLATION line (#2).

The IC Amplifier Unit provides the following features:

6 balanced SW configurable audio fixed inputs

•

Amplification of summed audio signal to 250 mW into 300 Ω or 500 mW into 8 Ω.

• Conditioning of mike audio to 50...400 mV into 150 Ω (standard carbon mike) or 0.5...4 mV into
20 Ω (dynamic mike):

- Automatic Gain Control (AGC).

- Providing the standard mike BIAS voltage supply.

•

Generation of a sidetone for the IC. The sidetone is SW configurable (all headsets

at the same time).

• Conditioning of mike audio for intercom operation:

- Enhancing to IC Audio Line level 0.775 V into 600 Ω.

- Intercommunication VOX level control by software.

•

•

6 control inputs for s

pecific logical IC-action.

•

3 control outputs for specific logical ex

ternal activations.

•

8 alert tone ac

tivation inputs (active low).

• Conditioning of mike audio to 50...400 mV into 150 Ω (standard carbon mike) or 0.5...4 mV into

20 Ω (dynamic mike):

- Automatic Gain Control (AGC).

- Providing the standard mike BIAS voltage supply.

• Generation of a sidetone for the IC.The sidetone is SW configurable (all headsets at the same time).

• Conditioning of mike audio for intercom operation:

- Enhancing to IC Audio Line level 0.775 V into 600 Ω.

- Intercommunication VOX level control by software.

• Addition of an incoming IC audio signal to the summed-up monitor audio; adjustment of the IC audio

level via the SW program by 0 .... -48 dB.

•

Interconnection and separation of the IC circuits by using a dedicated alert tone line.

Winchman Individual VOX level adjust is performed via discrete control lines (#1)

If the VOX level push button is pressed for a short time (0.3s to ≤ 3s), the VOX level is increased
by one step, until the maximum value is reached. If the VOX level push-button is pressed for a
time ≥ 3s, the VOX level will be reset to the value set on the corresponding SW location.

•

lnput definition for VOX-level adjust line will be as follows:

- Single click:
Active LO, Input voltage ≤ 1 V (min. LO time 0.3 s, max. LO-time ≤ 2 s)

- Reset click:
Active LO, Input voltage ≤ 1 V (LO-time > 3 s)

• Generation of up to 8 different alert signals (1 continuous, 3 pulsed, 4 intermittent) in the

frequency spectrum of 1200 … 4800 Hz. The quantity is depending on the total of HOTMIKE lines used.
Both functions can not happen at the same time.

These alert tones are activated via 8 discrete control lines (active LO ≤ 1 V) and addition of
those signals to the summed IC audio signal.

Via configuration software it can be set which of the alert signals are:

- Muted individually in each

- Headset set at the priority level

- Set at cancellation possibility

• Interface facility for IC Amplifier Unit configuration.

•

Initialization of a system selftest upon power-on (P_BIT) , a background test routine is continuously
running (C-BIT).

• Provision of 2 alternative internal operation voltage(s) from either of the airframe power supply buses.

•

Initialization of a system selftest upon power-on

(P_BIT) , a background test routine is continuously

running (C-BIT).

• Provision of 2 alternative internal operation voltage(s) from either of the airframe power supply buses.

• Relay controlled fall-back in case of emergency operation (Back up): Fix 1 to headset 1, and Fix

2 to headset 2 (intercomunication between headset 1 and headset 2 remains) . Back-up
operation can be iniciated manually by using an external hard-wired switch, or automatically upon
power supply failure to the IC Amplifier Unit, or, if any internal power supply of the Unit itself is
defective.

The audio processing circuits are realized in a modular design.

Section 2 INSTALLATION

2.1 General

The installation of the Intercom Amplifier Unit depends on the type of aircraft and its equipment and
therefore only general information can be given in this section.

Notice:

Changes or modifications made to this equipment not expressly approved by Becker Avionics,
Inc. and/ or Becker Flugfunkwerk GmbH may void the authorization to operate this

equipment.

2.1.1 Remark for the Intercom Amplifier Unit version IC6100-X-(XX)

If the memory device EM6100-(XXX) is replaced by a new one, it is important to be aware that the confi­guration data from the existing

IC6100 will be overwritten by the factory default data stored in the

memory device EM6100-(XXX).

2.2 Inspection before installation

Before installing the Intercom Amplifier Unit in an aircraft, carry out a visual inspection for any damage,
paying particular attention to the following:

- Dirt, dents, scratches, corrosion, broken attaching parts on the housing and housing parts.

- Dirt and scratches on the identification plate, front panel and marking.

2.5 Aircraft / Helicopter wiring

2.5.1 General

The plug and socket connection is shown from Fig. 2-5 to Fig. 2-11. The following points are to be ob­served for the wiring :

a. Only cable fit for aviation (self-extinguishing) shall be used. AWG 20 for power supply and AWG 24

for other cables.

b. The interface lines are each to be laid as 2-core twisted and screened (AWG 24) cables.

c. Every single cable harness of a unit connector must have separate screening.

d. Rubber sleeves are to be fitted over the soldering points on the unit connector.

e. A fuse or circuit breaker should be fitted in the power supply of the Intercom Amplifier Unit.

f. No RF cable should be included in the cable harnesses. Laying connecting cables together with ca-

bles which cary AF power or impulses is to be avoided.

g. Check the wiring carefully before switching on the units, particularly that (UB+) and (GND) have not

been mixed up.

Section 3 OPERATION

3.1 General Description

Information in this section consists of functions and operations for the IC Amplifier Unit.

The IC Amplifier Unit does not have any operator accessible controls.

All settings and adjustments to the operating parameters are made by the Configuration Software
CSW6100-X. For more information refer to the CSW-Software manual.

The IC Amplifier Unit is the core unit of the audio system and therefore the central connecting
point for all Headsets and audio inputs. The IC Amplifier Unit enables intercommunication
functions. All user headsets are connected to the IC Amplifier Unit.

Ten (10) internal signal tones can be activated by discrete signal from external. Eight signal tones
can be used as alert tones and configured with priority. Some other controls and indications are
possible. A detailed description will follow in the next sections.

3.2

Configuring the IC Amplifier Unit

A PC can be connected via CAN BUS interface with the IC Amplifier Unit. The individual operator

settings for control, specified from the operation requirements, can be configured by the Configuration

Software CSW6100-X.

3.3 External Memory EM6100-(XXX)

The EM6100-(XXX) is the memory device (optional). It is a small device connected to the Remote Elec-

tronic Unit and stores all system configuration parameters. It allows a quick field replacement of the Re-

mote Electronic Unit without reconfiguration of the

IC6100 on the bench.

3.4 Control Functions

3.4.1 Headset

The IC Amplifier Unit supports six headsets with dynamic or standard microphones. The sensitivity of
the microphone input and

the level of the phone output can be configured. Up to 12 headsets are

possible to be connected, 2 in parallel at each HS port.

3.4.2 Sidetone

The

IC Amplifier Unit can be configured for sidetone. The sidetone level can be adjusted in 3 dB steps

from 0 dB to -15 dB.

Page

3-2

DV 64480.DIC.01 Issue 1 Sep./2013

IC6100

3.4.3 Fix Input Channels (Warning audio tones)

The Intercom Amplifier Unit supports three direct input channels with input sensitivity adjustable from
5V – 40 V, and three direct input channels with input sensitivity adjustable from 2.5V – 20V under
main volume control.

Note!

FIX INPUT-Channels and Alert tones selectable with CSW6100 software for every user.

3.4.4 Cockpit Voice Recorder Output CVR

The Intercom Amplifier Unit supports two Cockpit Voice Recorder outputs for the combined mike and

phone signal, one from Pilot and the other from Copilot.

3.4.5 Alert Tones

The Intercom Amplifier Unit provides eight predefined alert tones. Each tone can be activated by a di­screte input signal (Low active). All type of tones are listed in section 1 paragraph 1.5.2.4 in this ma­nual.

A separate discrete input can be used to cancel the warning tones by an external switch.

Note!

For special mission operation some Alert tone activation input must be spend alternatively for

other operations!

In case of special mission configuration some alert tone activation inputs can be used for other functions:

• Alert tone 1, just this use.

•

Alert tone 2 for 3rd Intercom Circuit isolation control. This input isolates all users assigned to the
3rd IC - Circuit by the configuration software.

• Alert tone 3 to 8 for 6 IC Hot Mike Keys (headset without ACU configuration).

3.4.6 Signal tones

The IC Amplifier Unit supports two signal tones. One is the Intercom Request signal and the other is the

E-Call signal. Both signals can be enabled or disabled by the configuration.

3.4.7 Discrete Activation Signals

The IC Amplifier Unit supports external switches to be used to activate the signal tones for Intercom

Request and Emergency Call.

Page

3-3

DV 64480.DIC.01 Issue 1 Sep./2013

IC6100

3.4.8 Other discrete Activation Inputs

The IC6100 supports a selective call activation input. This input can be enabled or disabled by the

configuration. Its function will be similar that of the Alert tone 2 input control line.

3.4.9 Winchman operation

The Winchman functionality can be assigned to any headset port without installed physical ACU by the
configuration setup. With one external

push buttons the VOX level can be remotely controlled by the

Winchman operator.

By pressing one external push buttons the winchman function will be activated. This enables
the winchman to increase the VOX threshold level for his headset. The external push buttons in the
winchman work area (connected via discrete input lines) is mounted separately (near the cabin door).

3.4.10 Discrete Outputs for Indications

The Intercom Amplifier Unit supports output for the “Cockpit Call”, “Cabin Call” and the 3rd IC-circuit

disconnect indication.

• “Cabin Call” and “Cockpit Call” (Control OUT 2 and 3): active LO.

If "IC Request Call" (Control input line 2) is activated momentarily, the Cockpit call line will be solid LO

and Cabin CALL will be intermittent LO. If Control IN 6 (E-Call) is activated momentarily, will happen the

opposite.

• ”Third IC-Circuit isolated” (Control Out 4): active LO, if the Alert Tone 2 input line is activated momentarily.

3.4.11 Intercom Circuits

The Intercom Amplifier Unit supports 3 intercom Cir

cuits.

1. Cockpit-Cabin Crew.

2. 3rd IC-circuit (has to be controlled by an external switch).

3.

IC-Ring Line (connected to the Cabin-Cockpit or 3rd intercom circuit; configurable by the CSW ­Software).

Two of the Intercom Circuits (Cockpit and Cabin) can be directly controlled by the Audio Control Unit.
