Operation
Stand-Alone Router
2 A source is set of N inputs on the routers in the network, where N is the number of routers. A
source uses the same input on all N routers.
For example, source 12 comprises input 12 on router 1, input 12 on router 2, input 12 on
router 3, and input 12 on router 4. (All available levels are included in the source.)
3 If the operator routes source J to destination K , then input J is taken to output K on all
enabled levels. (A level — i.e., a router — is enabled when a level button selects it.)
Breakaway can occur when you choose different levels for separate takes to the same desti-
nation. (Breakaway is an undefined concept for a single router.)
A CR6400 network supports up to 64 sources, each of which can comprise up to 4 inputs, and
supports 64 destinations, each of which can comprise up to 4 outputs.
Stand-Alone Router
A “stand-alone” router is one operated independently with an attached CP6464 control panel.
(Automation is possible, but this document does not address automation.)
Startup
To power up a router, connect the 4-pin connector 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.
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.
At power-up, a control panel lights one of its level buttons, if the rotary switch of the router on
which it is mounted is set to a value in the range 1–4. If the rotary switch is set otherwise, the
control panel does not light any level button.
For a single stand-alone CR6400, level selection is disabled, although a level button might be
illuminated.
Takes
There are 4 very simple steps to perform a take (using a CP6464 panel):
1 Press the destination mode button. (The selection buttons turn amber, representing desti-
nations.)
2 Press one of the selection buttons to select a destination. The destination’s button goes
high-tally. It will be red if the destination is locked and the take will not be allowed.)
3 Press the source mode button. (The selection buttons turn green, representing sources.)
