User’s Guide
• Destination Mode.
The destination mode button enables destination selection using the array of selection but-
tons.
When a panel operator presses the destination selection button, we say the panel is in desti-
nation mode. The 64 selection buttons turn amber and permit the selection of one of 64 des-
tinations.
• Source Mode.
The source mode button enables source selection using the array of selection buttons.
When a panel operator presses the source selection button, we say the panel is in source
mode. The 64 selection buttons turn green and permit the selection of one of 64 sources.
Stand-Alone Definitions
The terms source and destination have specific meaning with respect to routers.
In general, a source is a set of associated input ports and a destination is a set of associated
output ports. (The source’s inputs connect to a device at which a signal originates. That can be
called a source device. A destination’s outputs connect to a device to which you are sending the
signal and that can be called a destination device.)
A level is the set of signals that are routed by one router. A network of 4 routers therefore has 4
levels — one for each router.
Breakaway is defined as a route in which a destination receives input from different sources on
different levels.
For a Single Router
1 A source is an input (i.e., a connector) on the CR6400 router.
2 A destination is an output (i.e., a connector) on the CR6400.
(When you have just a single router, the set of inputs for a source is just a single port and the set
of outputs for a destination is just a single port.
For a Router Network (Up to 4 Routers)
1 A source is set of N inputs on the routers in the network, where N is the number of routers. A
source comprises the same input on all N routers. (All levels are included in the source).
Example: in a network of 3 routers, source 5 is the set of input 5 on router A, input 5 on router
B and input 5 on router C.
2 A destination is set of N outputs on the CR6400s in the network, where N is the number of
routers. It is the same output on all N routers. (All levels are included in the destination).
3 If the operator routes source J to destination K, then input J on all routers is taken to output
K on all enabled levels. (A level — i.e., a router — is enabled when a level button on a CP6464
panel selects it.)
4 Breakaway can occur by choosing different levels for separate takes to the same destination.
(The concept of breakaway is undefined for a single router.)
