3.4 Wiring Requirements

3.4.1 Introduction

The installing agency shall supply and fabricate all external cables

and mating connectors. The length and routing of external cables

should 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.

3.4.2 Power Wires

Audio International recommends that power and ground wires be

20 AWG minimum. The chassis shall be electrically bonded to the

airframe structure by a conductive mounting point with <0.1 Ω

resistance using <50 Ω impedance cable. Aluminum wool, nylon

webbing impregnated with aluminum oxide abrasive or fiber bristle

brushes are the approved tools for removing anodized surfaces at

mounting point where the bonding wire is attached. Power and

Ground wires shall be in accordance with NEMA WC 27500 or

equivalent. Protect power wires with circuit breakers or fuses

located close to the electrical power source bus.

3.4.3 Video Lines

Composite video connections shall be shielded coaxial cable in

accordance with M17/94-RG179 or equivalent. Cable shields shall

be grounded at the source. Use of individual wires rather than

proper coaxial cable connections through production breaks is

unacceptable, and will cause significant and detrimental noise

3.5.3 The AI-LCD220-01-x utilizes three (3) connectors. P1 is a 9-pin

connector that provides power input, ground, video input, monitor

on/off control and monitor status.

The monitor on/off function (P1, Pin 5) is transition level sensitive.

Either a constant ground input or momentary ground input may be

used. If constant ground input is used, the monitor will activate to

the ON state when +28 VDC power is applied to Pin 1 and a

constant ground is on Pin 5. If no constant ground is present, then

this input will float to a high level causing the monitor to be in the

OFF state.

If momentary ground input is used, the monitor will alternate

between ON and OFF states with each momentary ground pulse of

duration between 50 and 250 msec. If momentary ground logic is

used, then the monitor will power up to an OFF state when power is

applied to Pin 1.

3.5.4 P2 is a 9-pin connector that provides power output to the SP-LCD4,

ground, and data bus control. Three (3) ID pins are also provided

on the P2 connector. These ID pins allow for up to eight (8) units to

be connected on the same AI proprietary RS-485 data bus while

maintaining independent control of each unit. Depending upon the

4.0 Troubleshooting

4.1 Instructions for Continued Airworthiness

No periodic scheduled maintenance or calibration is required for continued

airworthiness of the AI-LCD220-01-x. If the unit fails to perform to

specifications, it must be removed and serviced by a qualified service

facility.

4.2 Cleaning Method

The AI-LCD220-01-x should be cleaned at least once every three months

or when excessive dust or dirt becomes apparent.

Use a twin pack cleaning system that employs a wet pad pre-moistened

with an Isopropyl Alcohol based cleaner/anti-static solution and a lint-free

drying cloth. Audio International, Inc. recommends using “Kleen & Dry”

RR1205 manufactured by READ RIGHT, Nanuet, NY 10954.

 Do not use benzene, ammonia, thinner, or any other volatile

substance to clean the monitor or screen. These chemicals may

damage the screen or internal circuitry.

 Do not allow cleaner to puddle or pool around edges. Seepage

may damage internal circuitry.

Audio International’s recommended cleaning method follows:

A. Turn off monitor.

B. Open pre-moistened pad and gently wipe evenly across

display glass. Do not allow solution to “pool” or puddle

around display edges.

C. Immediately dry display using the absorbent, lint-free cloth.

Gently wipe display to a dry, clear finish.

4.3 General Troubleshooting Procedures

• Verify power to the unit by rechecking +28 VDC power is applied to the

proper pins on the unit. Use a voltmeter to verify correct level.

• Remove power from the unit for at least one (1) minute and reapply

power.

• Recheck all connections to the unit for security. Check all harness

runs for possible pinching. Recheck all pinouts for application

accuracy.

• Check data bus integrity by utilizing a voltmeter, oscilloscope, or other

voltage instrument to verify proper input voltage on the data bus pins.

Typical measurements are as follows:

A to Ground: 4.0 to 4.5 VDC

B to Ground: 0.1 to 1.0 VDC

If any device is transmitting (i.e., holding bus active), then these typical

measurements would be reversed for the A-to-Ground and B-to-

Ground. This troubleshooting tool can help indicate a data bus lockup.

If this occurs, remove the data bus from all other equipment one piece

at a time. As each is removed, check the bus status to see if it is now

functioning properly. Once you have removed the piece or pieces of

offending equipment, disconnect power and then reconnect everything

but the suspect component. Reapply power and then test the

functionality of the unit(s).
