FD322 Board


The FD322 board deals with CVBS, Y/C (S-video), YUV and RGB signals.
You can organize broadcasting of up to 2 independent channels via one FD322 board as it has 2 input and 2 output lines.
The board is plugged to PCI Express slot of PC mother board.
For commutation with external devices either a special cable (included into delivery product set) or a break-out box can be used (purchased separately).

Commutation of the Board With External Devices

For commutating of the board with external devices – sources and receivers of audio/video signal – either commutation cable or commutation panel (break-out box) are used.

Commutation cable has D-sub connector for connecting with FD322 board and a set of RCA connectors for connecting with external devices. All connectors are marked correspondingly.
The following devices in different combinations can be plugged to the board by means of a cable:

  • Sources of video signal: CVBS (up to 9), Y/C (up to 4), YUV (up to 3), RGB (up to 2);
  • Sources of audio signal: 4 mono or 2 stereo lines, non-balanced signal;
  • Receivers of video signals (up to 2 for each type of signal): CVBS, Y/C, YUV, RGB;
  • Receivers of audio signals: 4 mono or 2 stereo lines,
    non-balanced signal.
