Terminology
It is essential for the material that follows to define the terms “source” and “destination.”
In general, the terms source and destination refer to devices (e.g., VTRs, cameras, monitors) that
can be connected to the I/O cards of the router. In discussions of routers, we usually think of
sources and destinations only as the connectors to which a device is connected and we ignore
the devices. (In fact, the router functions properly regardless of whether it is actually connected
to any devices.)
A port is a single connector (DIN 1.0/2.3) on a router.
An input port, or just input, is one that receives a signal.
An output port, or just output, is one that sends a signal.
For a Single CR6400 Router
1 A source is a one input at the rear of the CR Series router.
2 A destination is one output at the rear of the CR Series router.
A CR Series router has a 64×64 switching matrix and thus supports up to 64 inputs and 64
outputs.
For a CR6400 Network
1 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.)
2 A destination is set of N outputs on the routers in the network, where N is the number of
routers. A destination uses the same output on all N routers.
For example, destination 55 comprises output 55 on router 1, output 55 on router 2, output
55 on router 3, and output 55 on router 4. (All available levels are included in the destination)
3 If the operator chooses source J and 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 CR Series 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 CR6400 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.
