There are 64 BNC I/O connectors on the Cougar3 rear panel, 32 each for video input and output signals,
as shown in Figure 3-5. Using the figure as a reference, connect video input and output cables to the
router.

Your Cougar3 router is capable of operating in either asynchronous or synchronous switching modes.
Asynchronous switching occurs when the router is not synchronized with other video equipment in the
air chain or production chain through an externally generated sync reference signal. In many
applications, asynchronous switching is acceptable, but in other circumstances synchronous, vertical
interval timed switching is used to prevent a visual "glitch" in the output signal when sources are
switched.
Your Cougar3 router functions in either mode, but is capable of synchronous, vertical-interval switching
by applying a NTSC, PAL or Tri-Level sync source, 0.5V p-p to 2.0V p-p, to the sync reference input.
Sync connectors 1 and 2 on the video frame are terminating connections. Sync input 1 is the default
sync source.
Cougar3 allows you to connect a second source of sync reference to the video frame through Sync Input
2. The second reference signal is often used in facilities dealing with mixed signal formats. Cattrax
allows you to selectively apply either sync reference signal to any router output.
