Operation
Startup
To power up a router, connect the 4-pin connector of the power supply to PS1 or PS2. Then plug
the power supply into AC power outlet. If you have chosen to use two power supplies for redun-
dancy, connect one to PS1 and the other to PS2.
At power-up, the router loads stored program code into its internal FPGA and restores its
previous operational state. (The “state” includes the crosspoint map between inputs and
outputs and which of the outputs are locked.)
 If a router’s rotary switch is set to the 0 position, the router reverts to the factory-default
state, not its previous state.
At power-up, the router detects the presence or absence of a video reference signal. It takes
about 10 seconds to lock to the reference rate.
At power-up, a control panel’s ‘Panel Lock’ button is on (red). You must turn panel lock off before
you can use the panel.
Level selection is disabled because the concept of levels does not apply to CQX routers.
Takes
Takes on a CQX panel involve transition type and rate when the destination selected is one of
the 2 CQX destinations. Takes do not involve transition type and rate when the destination is
one of the 6 auxiliary outputs.
To perform a CQX take, first press a CQX destination button. Then, optionally, choose a transition
type and rate. Then, press a source button. The take occurs nearly immediately (about 5 frame
periods later so that the video processor has time to lock to the new video source).
To perform an auxiliary take, simply press an aux destination button and then a source button.
The take occurs immediately (without a transition effect).
When you press a destination button, it tallies high (amber). The button for the source that
corresponds to the selected destination also tallies high (green). When you press another source
button, the old connection is lost (after the transition), the old source button goes low tally, and
the new source button goes high tally.
Pressing another destination button starts a new route.
 If a destination is locked, it will be low-tally red. If you press its button, it will go high-tally
red. You cannot perform a take for a destination that is locked. See
Locks , following.
Locks
The CQX panel has 7 function buttons. Only panel lock and destination lock are active. The other
5 buttons are disabled:
