3.3 Cautions and Warnings
3.3.1 It is important to do a pin-to-pin power and ground check on all
connectors. Ensure that power and ground are applied only where
specified. Damage to the unit may result if power or ground is
applied to the wrong points.
3.3.2 DO NOT remove any factory-installed screws. Damage to the unit
may result and void any warranties.
3.3.3 DO NOT expose to moisture.
3.3.4 ESD (Electro Static Discharge) guidelines shall be followed.
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
DeCrane Aerospace Audio International recommends that the
chassis 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. This unit provides for common circuit
ground and chassis ground connections. Both circuit and chassis

DeCrane Aerospace Audio International LCDP-9151-201 Installation Manual
Document # 540355, IR, 11/2007 Page 9 of 16
grounds are referenced to pin two (2) of connector P1. All case
grounds are recommended to be made with braided bond cable.
This connection should be made as close as possible (not to
exceed 6 inches) to the module. Alternatively, chassis ground can
be achieved by mounting the module directly to an electrically
conductive section of the aircraft frame. Power and ground wires
shall be in accordance with MIL-W-22759. Protect power wires with
circuit breakers or fuses located close to the electrical power
source bus.
3.4.3 Video Lines
All single signal connections shall be in accordance with MIL-W-
22759.
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
introduction to the video signal supplied to the LCDP-9151-201.
Serial digital video connections are recommended to use shielded
coaxial cable in accordance with PIC V76261 or equivalent.
SD-SDI video connections are recommended to use shielded
coaxial cable PIC V72261.
3.4.4 RS-485 Connections
RS-485 connections shall be twisted shielded cable with the shield
properly grounded at the source (ideal practice) and floating at the
load end. If shield cannot be grounded at the source, then ground
at the load end with the source end floating. Each wire length shall
be terminated at one end only. The shield for RS-485 shall be
terminated to a dedicated pin. Twisted shielded cable shall be in
accordance with NEMA WC 27500 or equivalent.
3.4.5 RGB Connections

5.0 Troubleshooting
5.1 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

DeCrane Aerospace Audio International LCDP-9151-201 Installation Manual

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).
