Application

Introduction

The LCD-9151-201-x is a flat panel LCD monitor with Composite video, PC Graphic capabilities, and Serial Digital interface capabilities. If any one of these formats is applied to their respective inputs, the monitor will display that format. In the case that both Composite and VGA are applied, the monitor defaults to the VGA input. The user can switch between inputs, or set video input priority, using the On Screen Display (see Section 3.8)

Communication

This unit incorporates an RS-485 serial data bus interface for communication purposes to other network-connected devices. All RS-485 serial data bus electronic interface parameters are compliant to AI document #640071.

Typical Application

Typical Interfaces

Typical Video Input (Analog) interfaces include various types of level compliant sources of Composite (SECAM, PAL, and NTSC), and XGA PC Graphics. The digital video input accepts SDI Video as defined by ANSI/SMPTE 259M-1997 digital format. SP-LCD6 is an external switch utilized for monitor set-up. The switch, which must be ordered separately, provides configuration control via AI’s proprietary RS-485 digital data bus communication or may be configured directly to the P2 connector. Refer to Section 3.8, Configuration Overview, for monitor set up. The SP-LCD6 may be removed and stored after the monitor is set up or can be mounted near the monitor for frequent use. Connector P2 provides to the switch panel +28 VDC power and ground input, serial data bus control, and unit ID strapping pins to allow the programming of multiple units. Device addressing is accomplished via three (3) ID pins, which allow for a total of eight (8) monitors to be independently addressed on the data bus. The monitor casing is specially designed for EMI and noise filtering, guaranteeing a reduction in interference to ensure a high-quality display. prevents undesirable heat buildup. Because this fan is thermostatically controlled, it only runs when heat build-up requires it, providing a much quieter viewing experience than many monitors. A shallow mounting depth makes this monitor ideal for bulkhead use. Convenient mounting holes are strategically located on the left and right sides. An optional front cover bezel (see Section 1.3) may be purchased for added mounting capabilities. Other plating options are available and allow matching to other cabin décor of the aircraft.

Installation

Prior to installation, the following items should be considered:

During the design and layout of the aircraft cabin, careful consideration of the location of this module is necessary. Some of the items to be considered include:

• Space
• Available power supply
• Environmental conditions (temperature, humidity, etc.)
• Length of cable runs

The LCD-9151-201-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. If the adjustment switch (SP-LCD6) is to be mounted in the aircraft, the following should be considered; the pigtail is 24 inches (60.96 cm) in length ±1 inch (2.54 cm) and has 6-32 x 0.75-inch mounting studs. Refer to Sections 5.0 and 6.2 for the adjustment switch characteristics. An internal fan exhausts heat from the unit. Proper ventilation must be allowed for when specifying the installation location. The closeout area of the monitor shall have a clearance of 2 inches (5.08 cm) minimum for the air inlet and exit areas. The closeout area of the monitor case shall not block the air inlet or exhaust openings of the monitor case. The fan will only run when the unit is turned on. Mounting provisions are provided via right-angle flanges attached to each side of the monitor case. These flanges provide the user with the means of mounting the unit. Refer to Section 6.0, Reference Drawings, for mounting hole diameters and configuration. The monitor should be located as close to the source equipment as possible in order to reduce the possibility of noise being introduced into the video. Refer to Section 6.0 for unit dimensions. The LCD-9151-201-x is configured using the external menu selection switch, SP-LCD6. The switch utilizes a D-Subminiature connector. This connector mates with the D-Subminiature connector on the LCD-9151-201-1 model monitor. A 3/8″ long grounding lug is included as part of the housing. See Section 6.0 for details. The maximum length of the connection to PC Graphic (VGA) input is 15 feet. ESD (Electro Static Discharge) guidelines shall be followed. Wiring Requirements 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 the installation of the equipment. Allow adequate space for the 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. Audio International recommends that the chassis 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 MIL-W-22759 or equivalent. Protect power wires with circuit breakers or fuses located close to the electrical power source bus. Composite video connections shall be shielded coaxial cable in accordance with M17/94-RG179 or equivalent. Cable shields shall be grounded at the source. The use of individual wires rather than proper coaxial cable connections through production breaks is unacceptable and will cause significant and detrimental noise introduction to the video signal supplied to the LCD-9151-201-x. Serial digital video connections are recommended to use shielded coaxial cable in accordance with PIC V76261 or equivalent.

The LCD-9151-201-x utilizes three (3) connectors. P1 is a 13-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. 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 necessary configuration, the ID 0, ID 1, and ID 2 pins shall connect to the ID common as suggested below:

Instructions for Continued Airworthiness

Airworthiness Limitations No periodic scheduled maintenance or calibration is required for continued airworthiness of the LCD-9151-201-x. If the unit fails to perform to specifications, it must be removed and serviced by a qualified service facility. Cleaning Method The LCD-9151-201-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:

• Turn off monitor.
• Open pre-moistened pad and gently wipe evenly across display glass. Do not allow solution to “pool” or puddle around display edges.
• Immediately dry display using the absorbent, lint-free cloth. Gently wipe display to a dry, clear finish.

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:

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).
