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
resistance using <50 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

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

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).
