Connecting To Video Devices
Video sources and output devices (such as monitors, or recorders) may be connected to
the routing switchers through the BNC type connectors located on the back of the unit.
Keep in mind that the output signal format will be that of the input signal format.
To ensure the highest quality of video routing and switching, special attention should be
paid to cables and connectors.
Connecting Peripherals
Control panels, video reference inputs, and power are all connected to the rear of the
frame. The peripherals area may vary depending on the model size and type.
Reference Connector
There are two BNC connectors labeled "VID REF". This is a "looping" input for SMPTE
analog video referencing. Connect composite, or tri-level sync to either BNC. If desired,
use the second BNC to loop the signal to another device. If the loop is not used,
terminate the second BNC with 75 ohms.
If a video reference signal is connected, switching will occur during the vertical interval of
the reference per SMPTE RP-168 and the supported video format standards shown on
page 19. If no reference signal is available, the routing switcher will switch at a random
point rather than during the vertical interval of the reference signal.
