Operating CR6400 Routers
Stand-Alone CR6400 Network
There must be from 1 to 4 routers whose levels are distinct and in the range 1–4. The level
buttons on the panel that correspond to the levels of the routers are illuminated and operable.
If the levels are not distinct, your network will not perform correctly.
Level Selection
A video or audio device typically receives or transmits signals of several types. A VTR might
handle HD, SD, AES, and machine control signals that need to be switched simultaneously. The
different signal types are considered “levels” in a router network.
In a stand-alone CR Series network, multiple levels can be taken to a destination simultaneously
(in a single button press).
In a stand-alone CR Series network, multiple levels of a destination can be locked simulta-
neously (again, in a single button press).
Example
Two levels, HD and AES, are taken from the VTR to the monitor:
The four level buttons on a control panel correspond to the four router levels, with level 1 on the
left and level 4 on the right.
A level button is illuminated (in amber) if a router at that level is present in the network. The
button is dark if not.
A level button is high-tally when the level is selected and low-tally when not.
Exceptions
In most cases, the level buttons are toggles: press the level button to select the level, press the
button again to deselect the level. However, there is an exception: when you have selected all
the levels in your network, pressing any level button deselects the other levels and leaves the
one you pressed selected.
Another exception is when you have only one router in your network. Pressing the level selec-
tion button has no effect. The single router is always selected.
Takes
A network of routers is capable of multi-level takes.
