Cobalt Digital COMPASS 9212-EO 3G_HD_SD-SDI Fiber Transmitter - Manual (Page 25)

9211-OE, 9212-EO User Manual User Controls •••• 3-3
• MUTE — This option mutes the card outputs when the input equalizer is unable to detect
a valid input signal, or when the reclocker is unable to lock to the input.
• NO MUTE — This option does not mute the card outputs on loss of input or lock. This is
the default setting.
4. Error! Reference source not found.
Use JP3 to determine the equalizer behavior when the Reclocker Rate is set to BYPASS (using
SW1 ). This jumper is only implemented for the 9212-EO. You can select one of the following:
• EQ — This option enables the input cable equalizer.
• NO EQ — This option disables the equalizer when the Reclocker Rate is set to BYPASS.
This option allows the card to pass signals that are outside the response band of the
equalizer reclocking, such as 143MHz. This is useful for non-SMPTE data rates.
5. Error! Reference source not found.
Use SW1 to set the reclocking rate of the card. Pressing SW1 cycles through the following
options:
• AUTO — This option enables automatic rate detection on the card. It will automatically
lock to input at any supported data rate (270Mbps, 1.5Gbps, or 3Gbps).
• BYPASS — This option enables the card to pass any data rate without reclocking. The
output is set to the HD slew rate except when the input is a valid SD data rate (270Mbps).
• 270M — This option configures the card to reclock at a rate of 270Mbps (SD).
• 1G5 — This configures the card to reclock at a rate of 1.5Gbps (HD).
• 3G — This configures the card to reclock at a rate of 3Gbps (HD).

SW3 is used for factory service in the unlikely event of a complete card failure. The Bootload
process is further described in the section “Bootload Button”.

The 9211-OE and 9212-EO use a blind mate LC/UPC connector to interface with the Rear
Modules. The rear module remains passive, while allowing for the 9211-OE or 9212-EO to be
replaced without the need to remove any connected BNC or fiber optic cables. The blind mate
connector is connected to the optical module via a single mode LC/UPC pigtail.
The fiber optic connector for the card includes a dust cap. The dust cap must stay on at all times
when the card is not installed in a frame. Ensure to keep the fibers end face clean and use the caps
to protect the fiber from scratches and collecting dust.
