AJA HD5DA video distribution amplifier The AJA distribution amplifier receives its signal from the Nvidia
SDI Output adapter and drives a VTR and broadcast monitor. The distribution amplifier is also necessary in
order to use the Real-Time Deliverables feature.
Wiring Your Video Components
Regarding connections to the Nvidia Quadro SDI Output adapter (slot 5), please note the following important
points:
■ Input port A of the VTR connects to the AJA HD5DA distribution amplifier (for 4:2:2 signal), and input
port B connects to the middle connector on the Nvidia SDI Output adapter (for dual link 4:4:4 signal).
The VTR output ports A and B connect to the SDI In A and B ports of the AJA breakout box.
NOTE The output of the AJA OEM-2K adapter, when ported through the AJA breakout box, can be used when
connected to a VTR that is not being used for Real-Time Deliverables. You can switch the output between the
AJA card and the SDI card though the application user interface.
■ VTR control is achieved through the RS-422 port on the AJA breakout box. See Standard VTR Control
Cable Pinouts on page 45.
■ Your facility’s sync source connects to the indicated connector on the Nvidia Quadro SDI Out adapter
card.
WARNING It is critical to connect the adapter card exactly as shown in the diagram to ensure the sync works
correctly.
■ Do not use an SD (NTSC or PAL) sync generator for HD projects. Always use a tri-level sync generator
for HD projects. Using the wrong sync generator for a project may impact the stability of your workstation.
