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 J2 provides to the switch panel +28 VDC power and ground input, serial data bus control, and unit ID strapping pins to allow 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.

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 LCDW-9420-101-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 6.2 and 7.2 for the adjustment switch characteristics.   An internal cooling fan ventilates internal components and prevents undesirable heat buildup. 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. This fan is thermostatically controlled, it only runs when the unit is turned on and heat build-up requires it, providing a much quieter viewing experience than many monitors.  The monitor casing is specially designed for EMI and noise filtering, guaranteeing a reduction in interference to ensure a high-quality display.

• A shallow mounting depth makes this monitor ideal for bulkhead use. Convenient mounting holes are strategically located on the left and right sides, as well as the back of the unit.

Instructions for Continued Airworthiness
No periodic scheduled maintenance or calibration is required for the continued airworthiness of the LCDW-9420-101-x. If the unit fails to perform to specifications, it must be removed and serviced by a qualified service facility.

Troubleshooting

Cleaning Method The LCDW-9420-101-x should be cleaned 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. DeCrane Aerospace Audio International recommends using “Kleen & Dry” RR1205 manufactured by reading 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.

DeCrane Aerospace 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 another voltage instrument to verify proper input voltage on the data bus pins. Typical measurements are as follows:
  •  to Ground: 4.0 to 4.5 VDC
  • 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).
