Important Regulatory and Safety Notices to Service
Personnel
Before using this product and any associated equipment, refer to the
“Important Safety Instructions” listed below to avoid personnel injury and to
prevent product damage.
Product may require specific equipment, and/or installation procedures to be
carried out to satisfy certain regulatory compliance requirements. Notices have
been included in this publication to call attention to these specific requirements.
Symbol Meanings
Protective Earth — This symbol identifies a Protective Earth (PE)
terminal, which is provided for connection of the supply system’s
protective earth (green or green/yellow) conductor.
This symbol on the equipment refers you to important operating and
maintenance (servicing) instructions within the Product Manual
Documentation. Failure to heed this information may present a major
risk of damage or injury to persons or equipment.
Warning — The symbol with the word “Warning” within the
equipment manual indicates a potentially hazardous situation which, if
not avoided, could result in death or serious injury.
Caution — The symbol with the word “Caution” within the
equipment manual indicates a potentially hazardous situation which, if
not avoided, may result in minor or moderate injury. It may also be
used to alert against unsafe practices.
Warning Hazardous Voltages — This symbol is intended to alert
the user to the presence of uninsulated “dangerous voltage” within the

Important Safety Instructions
1. Warning – Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. The safe operation of this product requires that a protective earth
connection be provided. A grounding conductor in the equipment's
supply cord provides this protective earth. To reduce the risk of
electrical shock to the operator and service personnel, this ground
conductor must be connected to an earthed ground.

Introduction
Overview
The SEA-9003 SDI Equalizing Amplifier is part of the GearLite 9000 digital
series of self-contained, small brick-format modules. The SEA-9003 is designed
for use in systems where signals of more than one digital standard are
distributed. The amplifier automatically equalizes up to 305m (1000ft) of
Belden 8281 input cable at 270Mbps, although 200m is the recommended limit
due to jitter considerations. Special measures have been taken to ensure
excellent return loss at both input and output. This guarantees error-free
performance with short cables.
The front panel of the SEA-9003 chassis provides visual performance indicators
with a power status LED and an input present status LED.
The SEA-9003 is delivered with a universal power adaptor and line cord
suitable for the country of use. Various mounting options are included that allow
a wide range of installation choices. The SEA-9003 provides a broadcast-quality
SDI distribution solution in a small, stand-alone package.

Installation
Static Discharge
Whenever handling the SEA-9003 and other related equipment, please observe
all static discharge precautions as described in the following note:
ESD Susceptibility — Static discharge can cause serious damage
to sensitive semiconductor devices. Avoid handling circuit boards in
high static environments, such as carpeted areas, and when wearing
synthetic fiber clothing. Always exercise proper grounding precautions
when working on circuit boards and related equipment.
Unpacking
Unpack each SEA-9003 you received from the shipping container and check the
contents to ensure that all items are included. If any items are missing or
damaged, contact your sales representative or Ross Video directly.
Mounting and Installation
The SEA-9003 can be mounted in any convenient location. However, to ensure
long life for this product, observe the following precautions and operating
requirements:
• Maintain an ambient temperature of 20°C to 40°C.
• Allow for air circulation around the chassis for convectional cooling.
Many different mounting positions are possible with the included mounting
hardware. Some installation options are permanent and require careful
consideration of the final positioning before installation. Please note that in
some mounting locations, the power adaptor must be affixed in a similar manner
as the chassis.
Other possible options include the use of adhesive magnetic sheets (not
included) affixed to the chassis and the power adaptor, for removable mounting
on metal cabinets etc.
Cable ties may be necessary in some applications to relieve strain on the
mounting hardware and the connectors.
Surface Mount Strips
The included VELCRO® brand surface mount strips allow the GearLite module
and power supply to be affixed to a permanent location during use and easily

removed for adjustments. Carefully consider the installation location before
proceeding; the adhesive is very aggressive and is not easily removed. The
adhesive will cure fully in 24 hours.
To install the Surface Mount Strips
1. Remove the Protective Backing Film from the adhesive on the
bottom of the two VELCRO® brand Surface Mount Strips.
2. Adhere the Surface Mount Strips to the bottom side of the chassis.
(Figure 2)
Figure 2 Surface Mount Installation Option
3. Remove the Protective Backing Film from the other side of the
VELCRO® brand Surface Mount Strips.
4. Press the chassis into position on the surface you want to mount it to.
Operating Tip — An additional VELCRO® brand Surface Mount
Strip is available to mount the power adapter.
Non-Slip Pads
Four non-slip adhesive pads have been supplied for desktop placements. Simply
remove the protective backing film from the adhesive and affix one non-slip pad
to each of the four corners on the bottom of the chassis.
Optional Mounting Accessories
Ross Video is committed to providing practical solutions for the needs of your
high-quality broadcast facility.

9 • Installation (Iss. 02)
Flat Metal Plate
Use the flat metal plate for permanent mounting to a rack, a desk, or any other
location where bolts or screws can be applied. Be sure to position the module to
allow for operator adjustments, if required.
To install the Flat Metal Plate
1. Remove the 2screws from the bottom of the chassis.
2. Install the Flat Metal Plate onto the bottom of the chassis (Figure 3)
using the screws provided in the Mounting Kit. Do not use the screws
removed during Step 1.
Figure 3 Flat Metal Plate Installation Option
3. Install the chassis in the desired location using the Mounting Holes
on the Flat Metal Plate. Mounting screws are not provided by Ross
Video.
Angle Mounting Bracket
The Angle Mounting Bracket (Figure 4) allows a single GearLite module to be
installed in positions not possible with the flat metal plate. The bracket has a 90°
angle. Mounting screws are not provided by Ross Video.

Setup
Power Adapter and Supply
Connect the PS-9000 power adaptor to the power supply connector. The
PS-9000 provides up to 2A of regulated +5V DC (5%). The DC power cord has
a locking connector that securely fastens into the power supply DC jack on the
SEA-9003. The SEA-9003 has a standard miniature power jack (center pin
positive).
If using an adaptor other than the PS-9000, ensure that:
• the polarity is correct
• the voltage is +5V DC regulated to 5%
• sufficient current for the SEA-9003 is supplied
Caution — Use of improper adaptors may damage the SEA-9003
and will void the warranty.
Installations outside of North America using line voltages of 200-240V require a
plug, certified for the country of use, to be installed on the supplied line cord.
Refer to the section “Important Regulatory and Safety Notices to Service
Personnel” at the front of this manual for details.
Cable Connections Overview
Connect the cables to the SEA-9003 according to the designations indicated on
the chassis label and Figure 5. The input is internally terminated at 75ohm. It is
not necessary to terminate unused outputs.
Figure 5 SEA-9003 Connections
Status LEDs
The front panel of the module has two LEDs that display the status of the input
signals and indicate whether the device is on or off. Figure 6 indicates the

restored correctly but the circuits will be working close to
the limit of their capability, and reliability cannot be
assured.
