Serial Digital A/V Splitter
1.0 General Information
1.1 Introduction
This manual contains information for the proper application, installation,
and operation of the Audio International, Inc. (AI), Serial Digital A/V
Splitter, Model # SDS-1001-101-x. The “-x” in the model number
designates the type of connector utilized in installation; “-1” = Positronic
and “-2” = D-Subminiature. Also included are relative physical and
electrical characteristics of the units.
1.2 Purpose of the Equipment
Audio International's SDS-1001-101-x Serial Digital A/V Splitter is a stand-
alone Serial Digital Audio (AES3) and Video (SMPTE259M) splitter that
simultaneously routes a single input to four (4) independent outputs. The
input incorporates cable equalization and the outputs utilize standard
cable drivers. Digital Audio functions as specified by AES3 standard,
including transformer coupling on inputs and outputs. No signal reclocking
is done. No command and control interface is required for this device; the
SDS-1001-101-x functions automatically when a signal is present.
The unit provides:
• One (1) AES3 (AES/EBU) serial digital audio signal input,
• Four (4) Simultaneous AES3 (AES/EBU) audio outputs,
• One (1) SMPTE259M serial digital video input, and
• Four (4) Simultaneous SMPTE259M SD-SDI video outputs
1.3 Optional Equipment
Audio International, Inc. offers a comprehensive family of Cabin Control
Modules for Passenger Control interface. These modules provide
convenient solutions for a variety of frequently encountered interfacing
needs or special requirements and are an important part of AI’s “building
block” system for configuring total cabin management.
Contact your AI representative for details.

3.0 Installation
3.1 Prior to Installation
The Serial Digital A/V Splitter is a simple module to install. Prior to
installation, the following items should be considered:
3.1.1 During the design and layout of the aircraft cabin, careful
consideration of the location of this and all other audio modules is
necessary. Some of the items to consider include:
• Space
• Proximity to other devices (i.e. source equipment or A/V box)
• Available power supply
• Length of cable runs
• Environmental conditions (temperature, humidity, etc.)
• Location of other aircraft systems (i.e. oxygen delivery)
• Access for service repair (if applicable)

Document #540306, Rev IR, 04/2005 Page 5 of 12
3.1.2 The module shall be installed to conform to the standards
designated by the customer, installing agency, or other specified
requirements.
3.1.3 Select a mounting location for the Serial Digital A/V Splitter before
installation. Refer to Section 7.0 for dimensions and attachment
points. The unit shall be bonded to the aircraft frame with a
bonding resistance of less than 0.01 Ω.
3.2 Unpacking and Inspection
3.2.1 Carefully open the packaging and remove the unit. Verify that all
components have been included in the package per the packing
list. Inspect the unit for shipping damage.
3.2.2 If damage has occurred during shipping, a claim should be filed
with Audio International WITHIN 24 hours and a Return Request
Authorization Number shall be obtained from AI by contacting the
Repair Department at 501.801.0640. Repackage the unit in its
original packaging materials and return it to AI following instructions
given by the AI representative. Refer to the front cover of this
manual for address. If no return is necessary, retain the packing
list and the packing materials for storage.
3.3 Cautions & 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 can result if power or ground is
applied to the wrong points.
3.3.2 DO NOT connect or disconnect the unit while power is applied.
3.3.3 DO NOT connect or disconnect any inputs or outputs when power
is applied to the unit.
3.3.4 DO NOT remove any factory-installed screws. Damage to the unit
can result and void any warranties.
3.3.5 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 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.
3.4.2 Power and Ground Wires
Power and ground connections are recommended to use 22 AWG,
minimum, wiring in accordance with MIL-W-22759 or equivalent.
3.4.3 Source Wires
Source input digital audio connections are recommended to use 22
AWG, minimum, shielded twisted pair cabling as necessary in
accordance with NEMA WC 27500 or equivalent.
3.4.4 SDI Video
SDI video connections are recommended to use shielded coaxial
cable V76261 from PIC Wire and Cable. Cable length limitations
are 50 meters with up to four (4) interconnects permitted, as long
as the connectors do not create in-line impedance (example - the
50 meter video cable can be broken up into five 10 meter
segments). In-line connectors must be rated the same
characteristic impedance; it must be designed for the cable and
installed properly. In the case of V76261 cable, the characteristic
impedance is 75 ohms. For longer cable runs, a transition to RG59
cable, using BNC connectors, can be made.
3.4.5 AES3 Serial Digital Audio
All digital audio wire connections must be twisted shielded cable
with the shield properly grounded to the dedicated pin at the source
end to the dedicated pin at the load end. Twisted shielded cable
shall be 22 AWG (minimum) for digital audio signals and shall be in
accordance with NEMA WC 27500 or equivalent. Cable
impedance must be 110 Ω+/- 10%.

Document #540306, Rev IR, 04/2005 Page 7 of 12
3.4.6 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 lines, maintain a separation of six (6)
inches between the lines.
3.5 Physical Characteristics
3.5.1 Locate the SDS-1001-101-x away from heat sources, magnetic
fields, direct sunlight, and areas with excessive dust and/or
moisture. The unit shall NOT be mounted to the skin of the aircraft.
3.5.2 This unit is capable of sustained intended operation with no internal
cooling fan air circulation, intake, or exhaust and no ventilation
holes in the chassis. Additionally, this unit does not require external
direct air-cooling for proper operation. Installation recommendation
requires 1-inch spacing from other equipment, modules, and
structures except the mounting surface for which the unit should be
in direct contact.
3.5.3 Mounting provisions are provided via four (4) 0.144-inch diameter
mounting holes – two (2) on each side of unit on provided mounting
flanges. The unit shall be rigidly mounted to its location using the
appropriate fastening hardware supplied by the installing agency.
3.5.4 When mounting the unit to the aircraft’s frame, allow sufficient
space for mating connectors. Refer to Section 7.0 for unit
dimensions and mounting hole sizes.
