Configuration
This chapter briefly outlines how to configure the QRA-8808 using the options available in DashBoard.
Enabling the Failover Feature
The failover feature enables the QRA-8808 to use a backup input source when the primary input source is lost and
the backup input is stable for at least 3 seconds. Once the QRA-8808 determines that the primary input source is
stable for at least 3 seconds, it automatically switches back to the primary source. The
Input field on the Signal tab
reports when the backup source is in use for each channel.
The source assignments are fixed for each channel as follows:
• Channel A — IN 1 is the primary input source and IN 2 is the backup source.
• Channel B — IN 2 is the primary input source and IN 1 is the backup source.
• Channel C — IN 3 is the primary input source and IN 4 is the backup source.
• Channel D — IN 4 is the primary input source and IN 3 is the backup source.
To enable the failover feature
1. From the Device View , select the Setup tab.
2. Select the Enable Failover box for the channel.
The box displays a check-mark.
Configuring the Equalizer for a Channel
You can choose to enable or bypass the equalizer for each channel. The equalizer enables the card to compensate for
noise and signal losses inherent in long coaxial cable runs. Refer to the chapter “
Technical Specifications ” on
page 27 for information on the cable equalization specifications.

You must bypass the equalizer when using signals of less than 125Mbps (such as SMPTE 310 signals). For
signals 125Mbps and greater (such as SDI signals), you must enable the equalizer.
