Document # 540204, Rev IR, 1/2001 Page 6 of 19
6.2.2 The unit can also be configured for IR remote control utilizing AI’s
remote control unit AI-RC1-17xxxx and IFR-9A. This following
configuration utilizes a +5 VDC digital logic level for activation of
infrared commands. Connection to multiple IFR-9A units using the
+5 VDC digital logic connection requires use of external Schottkey
diode connection at each IFR-9A unit to prevent signal loading.
Contact AI for details.
6.2.3 The unit can also be configured for Touch Screen or remote panel
control (i.e. entertainment control panels). The panels are on AI’s
proprietary RS-485 digital data bus system and configured to
control the operational features of the RCP-201-01-x.

SECTION II - INSTALLATION
1.0 Prior to Installation
1.1 During the design and layout of the aircraft cabin, careful consideration of
the location of this and all other audio/visual modules is necessary. Some
of the items to be considered include:
• Space
• Available power supply
• Environmental conditions (temperature, humidity, etc.)
• Length of cable runs
• Location of other aircraft systems (oxygen delivery)
1.2 The RCP-201-01-x shall be installed to conform to the standards
designated by the customer, installing agency, and existing conditions as
to the unit location and type of installation.
1.3 Mounting screws are required to secure the unit. Refer to Section II, 9.0
for mounting hole diameters and configurations.
1.4 Long low-level audio runs may introduce noise into the audio signal. All
headphone amplifiers and line level amplifiers should be located no more
than three (3) feet away from source equipment.
1.5 Audio level adjustment controls are located on the rear of the unit. The
level controls must be accessible for periodic system adjustments.
1.6 The installing agency shall supply and fabricate all external cables to the
RCP-201-01-x. The length and routing of external cables shall be
carefully studied and planned before attempting installation of the unit.
Allow adequate space for installation of cable and connectors. Mating
connectors are the responsibility of the installing agency. Correct pin
assignments as outlined in Section II, 6.7 are the responsibility of the
installing agency.

4.0 Wiring Requirements
4.1 Introduction
The installing agency shall supply and fabricate all external cables. The
length and routing of external cables shall be carefully studied and
planned before attempting installation of the equipment. Allow adequate
space for installation of cable and connectors. Avoid sharp bends and
placing cables near aircraft control cables. Maintain a minimum clearance
of three (3) inches from any control cable. If wiring is run parallel to
combustible fluid or oxygen lines, maintain a separation of six (6) inches
between the lines.
4.2 Power Wires
All power and ground wires shall be 22 AWG, MINIMUM. Power ground
wires shall be grounded within twelve inches of the unit. All wires shall be
in accordance with the standard military specification of MIL-W-22759 or
equivalent. Twisted, shielded cable shall be in accordance with the
standard military specification of MIL-DTL-27500 or equivalent. Protect
power wires with circuit breakers or fuses located close to the electrical
power source bus.
4.3 Audio Wires
All audio wire connections require twisted shielded cable with the shield
properly grounded at the source. Twisted shielded cable shall be in
accordance with the standard military specification of MIL-DTL-27500 or
equivalent.

cable in accordance with the standard military specification of
MIL-DTL-27500 or equivalent. The wire size for the conductors in
this cable shall be 22 AWG, MINIMUM. The shield shall be
connected everywhere a shield pin is provided. Shield terminations
shall be made as close to the connector pin as possible.
4.4.2 All modules on AI’s proprietary RS-485 data bus shall be connected
in a ‘daisy-chain’configuration. AI’s proprietary RS-485 data bus
specification is available upon request.

6.2 The RCP-201-01-x utilizes one (1) 15-pin connector for electrical
connections. This connector provides power, data bus control, infrared
input, and three (3) infrared strapping pins for alternate configuration of
infrared digital command codes.
6.3 Standard configuration requires no infrared strap pins to be connected.
Each different type of AI source equipment can be configured to accept
one (1) of four (4) different sets of infrared codes. To change the code
settings, connect one (1) of the strap pins to the strap common (never
connect more than one (1) strap pin to the strap common). Three (3)
strap pins are available to allow the infrared codes to be configured.
6.4 The infrared input provides a ground reference connection (-). For
optimum infrared signal transmission, this ground reference connection
should connect along with the chassis ground reference connection (pin 2)
to the same ground termination location as that of the IFR-9A or IFR-485
module being utilized. If this is not possible, then the infrared ground
reference connection for the RCP-201-01-x shall be made within 12" of the
unit.

8.0 Troubleshooting
8.1 General Troubleshooting Procedures
Many problems can be isolated with the following general techniques:
• To verify power to the unit, recheck +28 VDC power is applied to the
proper pins on the unit. Use a voltmeter to verify correct level.
• Reset by removing power from the unit for at least one minute and
reapply power. Verify the problem still exists.
• Recheck all connections to the unit for security. Check all harness
runs for possible pinching. Recheck all pinouts for application
accuracy.
• To check data bus integrity, utilizing a voltmeter, oscilloscope, or other
voltage instrument, verify proper input voltage on the data bus pins.
• The RS-485 data bus is a bi-directional bus that does not have a ‘bus
controller’. The bus uses a differential digital signal that will transmit
only when commands are entered via switch selection or other system
synchronizing commands. The “A”leg of the bus is HI and the “B”leg
LOW.
