Two sets of looping BNC inputs are provided to accept two independent reference signals
supporting the following reference signal types:
• Analog black
• Tri-level sync
• AES/DARS reference
This feature distributes one or two reference signals to all cards in the frame. Cards which need an
external reference use this master reference signal in place of taking the signal from one of the card
BNCs. This provides for ease of installation and reduction in reference cabling requirements. If
this signal is required, it will be mentioned in the “Installation” section of the card User Manual.
If only one reference type is required for the frame, connect it to the REF-1 BNC. If the reference
is not being looped to another frame or device, ensure that the Loop Ref BNC is terminated.
