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 the
grounding lug with <0.1
resistance using <50
impedance
cable. Power and Ground wires shall be in accordance with
M22759 or equivalent. Protect power wires with circuit breakers or
fuses located close to the electrical power source bus.

Page 9 of 21
DeCrane Aerospace Audio International
SCD-301-01-x Installation & Operation Manual
3.4.3 Analog Audio Wires
To reduce the opportunity for electrically-induced ground-loop
noise, DeCrane Aerospace Audio International recommends that all
analog audio wire connections 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. The shield for
each cable length shall be terminated at one end only. Terminating
both ends of a shield is NOT recommended, and highly increases
the likelihood of creating unwanted electrically-induced ground-loop
noise into the analog audio signal. Twisted shielded cable shall be
22 AWG (minimum) for low-level audio signals or 16 AWG
(minimum) for speaker-level audio signals and shall be in
accordance with NEMA WC 27500 or equivalent. Individual
conductor wire gauge in each twisted shielded cable assembly shall
increase accordingly with analog audio signal type and any
significant increases in cable routing.
3.4.4 DAAI’s Proprietary RS-485 Data Bus
The SCD-301-01-x is designed to interface with other DeCrane
Aerospace Audio International equipment via DAAI’s proprietary
RS-485 serial data bus. The data bus shall be implemented using a
twisted shielded pair cable in accordance with NEMA WC 27500 or
equivalent. The wire size for the conductors in this cable shall be
22 AWG, MINIMUM. Shield pins are available for connecting data
bus shields when required.
Refer to DAAI document 650007 for RS-485 Serial Data Bus
design architecture.
3.5
Physical Characteristics
3.5.1 Refer to Section 8.0 for unit dimensions and attachment points.
3.5.2 When mounting the unit, allow sufficient space for mating
connectors.
3.5.3 Do not insert any screw more than 0.50" into the case. Mounting
holes on the unit provide multiple anchoring points. These threaded
inserts do not have physical stops. Care should be taken not to
penetrate the outer casing with any screw more than 0.50". This
could result in serious damage to the CD Player.
3.5.4 Allow a MINIMUM of one (1) inch of air space around the unit to
allow for proper air circulation. This unit has an internal fan and

ventilation holes in the chassis for cooling. Installation
recommendation requires 1-inch spacing from other components
and structures except the mounting surface for which the unit
should be in direct contact.
3.5.5 Bonding between chassis mounting point and airframe installation
to be <0.1 ohm resistance using <50 ohm impedance cable. No
surface prep is required due to conductive chassis.
3.6
Clearance and Separation Requirements
When running cables, 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

5.0
Troubleshooting
In addition to the cautions and warnings provided in Section 3.3, the following
guidelines and instructions will help ensure proper functionality and performance
from the SCD-301-01-x.
5.1
Cleaning Method
SCD-301-01-x should be cleaned routinely at least once every three (3)
months to ensure proper functionality. Use a standard DVD cleaning disc
(not included with the SCD-301-01-x) and follow the listed directions.
5.2
General Troubleshooting Procedures - many problems can be isolated
with the following general techniques:
•
•
•
•
•
To verify power to the unit, recheck +28 VDC power is applied to the proper pins on
the unit. Use a voltmeter to verify correct level.
Reset by removing power from the unit for at least one 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.
To check data bus integrity, utilizing a voltmeter, oscilloscope, or other voltage
instrument, verify proper input voltage on the data bus pins. Typical measurements
with no device(s) on bus transmitting 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
measurements. This troubleshooting tool can help indicate a data bus lockup.
The RS-485 data bus is a bi-directional bus that does not have a ‘bus controller’. The
bus uses a differential digital signal that will transmit only when commands are
entered via switch selection or other system synchronizing commands. The “A” leg of
the bus is HI and the “B” leg LOW.
