Connecting the Dual-Link HD SDI Board
The Dual-Link HD SDI board is used whenever you need to input or output using 4:4:4
format. When using this format you should not attempt to use connections on the Nitris
DNA box.
The dual-link HD SDI board is divided by use into two sections:
• 4:4:4 format video using 4 mini-BNC connectors.
• AES Audio embedded with the video breakout cable — 15-Pin D connector for 8
channels of AES/EBU audio inputs and outputs. The connector attaches to a 8-XLR
breakout cable. It is 24 bit, 48Khz audio. Inputs support 32 bits at 96Khz.

The remaining sections of cable are not used. The above two functions are the only ones
supported at this time.
To connect the Dual-Link video and sync:
The dual-link board has 1 dual-link input (2 connectors), and 1 dual-link output (2
connectors). The inputs should normally be connected to a dual-link capable deck, and the
outputs can either go back to the deck, or feed a HDLink-type device for display on a
computer monitor. Sync on the board is always an input and should be feeded with the same
sync that is feeded to the deck connected to the AJA board. It's used to sync both the Audio
and Video when in playback mode.
