Connecting Audio Clock and Sharcnet Cables
This section describes how to connect coaxial audio clock cables and Sharcnet
ribbon cables between the Audio Signal Processing Boards (ASPB) and the video
I/O boards. It includes four cabling examples that cover most DVCPRO
configurations for the PDR 200. If after looking at the cabling examples you still
have a question about how to connect ASPB cabling in your system, refer to
“Detailed Explanation Of ASPB Cabling” on page 50. General guidelines are
given there to help you connect cables as required. After you have connected all
the ASPB cables, return to the installation procedure you were following.
Read the following paragraphs which give a brief functional description of the
cables connected to the ASPB, then proceed by looking at the cabling examples.
• Audio Clock Cables - These cables connect the ASPB to the video input
boards. The ASPB uses the clock signals from the video boards as a
reference to synchronize audio sampling to non-synchronous video feeds.
• Sharcnet Ribbon Cables to Serial Digital Video I/O boards - The Sharcnet
ribbon cables carry the embedded audio signals to and from the ASPB.
• Sharcnet Cables Between ASPBs - If two ASPBs are installed in a unit, they
must be connected together using these Sharcnet ribbon cables.
