SEA-8008 User Manual (Iss. 05A) Introduction • 1-1
Page 10
Overview
The SEA-8008 Serial Equalizing Amplifier is designed for general SDI equalizing and distribution use
where the outputs must all be non-inverted. It suits applications where multiple outputs are required,
but where reclocking is not required. Although the amplifier automatically equalizes up to 305m
(1000 ft.) of Belden 8281 input cable at 270Mb/s, 200m (656 ft.) is the recommended limit due to jitter
considerations. Special measures have been taken to ensure excellent return loss on both input and
outputs. This design guarantees error-free performance, even with short cable runs.
A very useful feature of the SEA-8008 is the card-edge LED status indicators, which confirm the
presence of an input signal capable of equalization.
The SEA-8008 operates on all serial digital standards, from 143Mb/s up to and including 360Mb/s. All
eight outputs are non-inverting, and so they can be used for the distribution of DVB/ASI signals, as
well as SMPTE 259M signals.
The SEA-8008 is designed to operate within the RossGear 8000-series digital products frame. Ten
amplifiers can be installed in a Ross 2-rack unit frame, and four amplifiers in a Ross 1-rack unit frame.
This amplifier also fits Leitch
*
6800-series frames.

Static Discharge
Whenever handling the SEA-8008 and other related equipment, please observe all static discharge
precautions as described in the following note:
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-8008 you received from the shipping container, and check the contents against the
packing list to ensure that all items are included. If any items are missing or damaged, contact your
sales representative or Ross Video directly.
Fault Reporting Setup
See Chapter 3, “SMPTE 269M Fault Reporting” for complete details.

Board Installation
Use the following steps to install the SEA-8008 in a RossGear 8000 series digital distribution frame:
1. Refer to the User Manual of the RossGear 8000 series frame, to ensure that the
frame is properly installed according to instructions. If this module is to be installed
in any compatible frame other than a Ross Video product, refer to the frame
manufacturer’s manual for specific instructions.
2. Please note that heat and power distribution requirements within a frame may dictate
specific slot placement of cards. Cards with many heat-producing components
should be arranged to avoid areas of excess heat build-up, particularly in frames
using convectional cooling.
3. After selecting the desired frame installation slot, hold the SEA-8008 card by the
edges and carefully align the card edges with the slots in the frame. Then fully insert
the card into the frame until the rear connection plug is properly seated.
BNC Labels
Affix the supplied BNC label, as per the included instructions, to the BNC area on the rear of the rack
frame.
Cable Connections
This section provides instructions for connecting cables to the SEA-8008 when mounted in RossGear
8000 series Digital Products Frames. The cable connectors on the rear of the frame are marked for
distribution amplifiers having one input and eight outputs. The SEA-8008 cable connections match
the frame designations.
Connect the input and output cables according to the frame rear panel connections diagram in the
following figures. The inputs are internally terminated in 75 ohms. It is not necessary to terminate
unused outputs.

LEDs
The front edge of the module has two LED indicators, which show the status of the amplifier. They are
described in the following figure and table.
INPUT OK LED

Table 1. LED Status Indicator Descriptions
LED Color Status Description
When lit, the module is operating correctly. This indicates that the
INPUT OK Green

input signal is suitable for achieving error-free performance, and is
within the capability of the cable equalizer to restore the signal.
When lit, the input signal is too low or absent. In some
circumstances, the signal may still be restored correctly but the
circuits will be working close to the limit of their capability, and
reliability cannot be assured.

SMPTE 269M Fault Reporting
In This Chapter
This chapter contains the following sections:
• Overview
• Jumper Setup
• Frame Connections
• Details
Overview
The SMPTE 269M Fault Reporting system, also known as a SMPTE “alarm”, provides indication if
one or more frame modules encounter a fault or an abnormal condition. The SEA-8008 module
provides a jumper to enable SMPTE-269M fault reporting. The card connects by means of an internal
interface circuit to an auxiliary telco connector on RossGear 8000 series frames. When the frame
connection is interfaced with a customer-designed system of LEDs or audible alarms, faults can be
traced to a specific frame when a card fault occurs within that frame.
The following diagram illustrates a general arrangement for SMPTE 269M alarm reporting:
Figure 4. SMPTE 269M Alarm Reporting: Internal interface and typical connections
SEA-8008 User Manual (Iss. 05A) SMPTE 269M Fault Reporting • 3-1
Page 18
Jumper Setup
If fault reporting for the SEA-8008 is desired, use jumper JP2 - FAULT REPORT (269M) to set up
the card.
1. To access the jumper, remove the card from the frame by pressing down the white
card ejector tab and pulling the card from the frame slot.
2. Observing all static discharge and handling precautions, place the card with the
component side facing up on a clean flat surface.
3. To enable SMPTE fault reporting, set jumper JP2 to ENABLE position.
4. To disable SMPTE fault reporting, set jumper JP2 to DISABLE position.

Frame Connections
The SMPTE 269M Fault Reporting connection on RossGear 8000 series frames is provided by the
auxiliary telco connector, AUX A, for interfacing with a customer-designed alarm system.

Details
The fault report contacts are closed when the card detects an internal failure or a power loss condition.
The fault report will pulse off for 1 to 2 ms about every 16ms if the input signal is low or missing.
Some internal failures are:
• Failure of the card to initialize
• Failure in the fault reporting circuitry
• Failure to detect a valid input signal to the card
For additional information on alarm system design, refer to the SMPTE document ANSI/SMPTE
269M - 1999.

Troubleshooting Checklist
Routine maintenance to this RossGear product is not required. In the event of problems with your
SEA-8008, the following basic troubleshooting checklist may help identify the source of the problem.
If the module still does not appear to be working properly after checking all possible causes, please
contact your Ross Video products distributor, or the Ross Video Technical Support department at the
numbers listed under the “Contact Us” section at the end of this manual.
1. Visual Review – Performing a quick visual check may reveal many problems, such
as connectors not properly seated or loose cables. Check the module, the frame, and
any associated peripheral equipment for signs of trouble.
2. Power Check – Check the power indicator LED on the distribution frame front
panel for the presence of power. If the power LED is not illuminated, verify that the
power cable is connected to a power source and that power is available at the power
main. Confirm that the power supplies are fully seated in their slots. If the power
LED is still not illuminated, replace the power supply with one that is verified to
work.
3. Reseat the Card in the Frame – Eject the card and reinsert it in the frame.
4. Check Control Settings – Refer to the Installation and Operation sections of the
manual and verify all user-adjustable component settings.
5. Input Signal Status – Verify that source equipment is operating correctly and that a
valid signal is being supplied.
6. Output Signal Path – Verify that destination equipment is operating correctly and
receiving a valid signal.
7. Module Exchange – Exchanging a suspect module with a module that is known to
be working correctly is an efficient method for localizing problems to individual
modules.
