still occur at the specified switchpoint for the video reference, but they will not be “clean and
quiet.”
However, if there is no video reference present, the CQX does the cut to the new source as soon
as it receives the command from the control panel and does not wait for the switchpoint.
Where one or both of the sources is off-rate or at a frame rate different from that of the video
reference, the output will bypass the video processor.
If a clean and quiet output is in a non-sync state but conditions change so that a clean switch is
possible, the processor waits for one frame of video before switching to processed video to
ensure that the processed video has enough time to pass through the video processing path.
The CQX video routers have a removable fan unit. The fan unit is not visible when a CQX panel is
mounted on the router.

Customers should have no reason to remove the fan unit.
The CQX video routers have a “mode” switch in addition to the 16-position frame ID switch. Both
are 16-position rotary switches that turn with a small screwdriver. The “mode” switch configures
the video format of the router. See
on page 81 for details.
Set the rotary switch to a position in the range 0–9, A, B, C, or D, according to this table:
The default is 1080i, 59.94 Hz (switch setting 0). Positions E and F are not valid positions.
Where a switch setting supports multiple formats, the format is governed by the video reference
applied to the router and must be compatible with that reference format.
The CQX routers enter non-sync bypass mode for signals at other rates.
When a control panel is mounted on a router or remote panel module, it conceals the rotary
switch. You must remove the control panel when you are setting the rotary switch.
Every time you make a switch change, power-cycle the router or remote panel module.
