Overview
The SRA-8201 is a single channel Multi-Definition SDI distribution amplifier, capable of equalizing
and reclocking all common serial digital signals. Support for both standard-definition and high-
definition signals makes the SRA-8201 a universal SDI distribution amplifier.
The SRA-8201 equalizes the incoming SDI signal, compensating for up to 300m of cable at 270Mb/s
and over 120m of cable at 1.485Gb/s. The signal is then reclocked with automatic rate detection for all
popular data rates. LED indicators at the front of the card identify the presence of incoming video and
the identified signal data rate for each channel independently.
Ten amplifiers can be housed in an 8300 series frame.

Jumper Locations
The following sections describe the jumpers on the SRA-8201.
Figure 2. Jumper Locations
JP1 ⎯Card Control
Note JP1 controls access to card jumpers only. The card edge
buttons can configure their parameters regardless of the setting.
JP1 selects whether the Output Mute and Output Channel Configuration jumper settings are respected
or ignored when using the external remote control system. Using Figure 2, the card labeling, and the
following descriptions, select one of the following options on JP1:
• REMOTE — the local jumper settings are ignored and the card is configured
remotely.
• LOCAL — the local jumper settings are respected and the card is controlled locally.
The card controls and status can be read remotely but not changed (default setting).
JP2 ⎯Loss of Signal
Using Figure 2, the card labeling, and the following descriptions, select one of the following options
on JP2 to enable or disable the Loss of Signal option:
• MUTE — a channels outputs will be muted if the input signal degrades to the point
that the input EQ can no longer guarantee error-free performance. When the red
ERROR LED is on, the outputs will be muted.
If you have input channels set to any rate other than Auto mode, we recommend this
jumper position. The output of the card would then mute if an incorrect data rate is
applied to the input, or if the input signal became too weak for the input equalizer to
compensate for.
• NO MUTE — a channels outputs will work to the limits of the input stage (default
setting).
2-2 •Installation and Setup SRA-8201 User Manual (Iss. 04)

Figure 6. LED and Rate Selection Switch Locations
SRA-8201 User Manual (Iss. 04) Installation and Setup •2-5

PWR (Power) LED
The top front edge of the card has a Power LED which indicates card status. The Power LED displays
green when the card is operational. If the card is not operational or the LED is not displaying green,
refer to the chapter, “Service Information”, of this manual.
OK/Error LED
Channel A has an OK/ERROR LED. The LED displays the following conditions:
• Green — channel is reclocking a valid signal.
• Red — invalid signal or rate setting, channel cannot reclock.
Channel Rate Selection Buttons and LEDS
Channel A has a rate selector button and rate LEDs to set the input signal rate that the channel will
process. Pressing the button will illuminate a corresponding LED. Repeated presses will cycle through
the selections.
For most applications, setting the Channel Rate to AUTO (default setting) will allow the SRA-8201 to
automatically detect the incoming data rate. In AUTO mode, the Data Rate LEDs will display the data
rate detected from the incoming SDI signal.
For applications where only one specific data rate will be used, and the fastest possible lock times are
desired, the SRA-8201 can be locked to a specific data rate. Press the Channel Rate Selection Button
until the AUTO LED is off, and the specific data rate LED is illuminated. Only SDI signals matching
the selected data rate will be reclocked and passed through the SRA-8201.
Bootload Button
This button can be used to reset a channel to factory settings. Refer to the section below for details.
This button is used for factory service in the unlikely event of a complete card failure. The Bootload
process is further described in the chapter, “Service Information”, of this manual.

Remote Control
In This Chapter
This section provides a detailed explanation on using remote control functions with your SRA-8201.
The following topics are discussed:
• DashBoard Control System Software
• SNMP Monitoring and Control
DashBoard Control System Software
The DashBoard Control System enables you to monitor and control openGear frames and controller
cards from a computer. DashBoard communicates with other cards in the DFR-8310 frame through the
MFC-8310-N Network controller card. This card is required in order to use DashBoard to configure
the SRA-8201.
The DashBoard software and manual can be downloaded from the Ross Video website.
Using the Menus
You must first install the DashBoard Control System software on your computer. Refer to the
DashBoard User Manual for software installation procedures and using the DashBoard interface.
The Menu System
The following table and sections describe the menus, items, and parameters available from the
DashBoard Control System software for the SRA-8201 Reclocking Amplifier.
Note In the Setup menu, if you have input channels set to any rate other than
Auto Mode, the Mute option is recommended. The output of the card
would then mute if an incorrect data rate is applied to the input, or if the
input signal became too weak for the input equalizer to compensate.
Note In the Setup menu, when Auto is selected as an input rate, the data rate of
177 MHz is not detected..
