Introduction
Hardware Summary
Routers
With the exception of the machine control routers, all the compact routers are X/Y routers
having n × m crosspoint matrices. An input can be routed to any or all of the outputs.
The machine control routers (also called port routers) are point-to-point routers. An input can be
connected to at most one output. (The connections are RS485 or RS-422 and bidirectional, typi-
cally with control commands in one direction and responses in the other direction.)
Each of the 3 “clean and quiet” (CQX) router models routes 16 inputs to 2 “clean and quiet”
outputs or to 6 auxiliary (normal) outputs. For the clean and quiet outputs, the router performs
smooth transitions. The transitions are governed by transition type and transition rate, select-
able on the CP1602-CQX control panel. The CQX routers also provide 2 bypass inputs. The 2
clean and quiet outputs switch to the bypass inputs if the router loses power.
The CR6400 routers (2RU) are newer in design, have removable I/O modules, and are deeper
(about 10” or 25
cm) than other CR Series routers. Otherwise, they operate much like other CR
Series routers.
Control Panels
A CR Series control panel mounts on the front of a router or on the front of a remote panel
module. The panel provides direct visual and tactile control of the router (or of the routers in a
network). (You can install or uninstall one easily in a few seconds.) However, any of the routers
can also operate without a control panel, under network control or through automation.
The CP3201 is special case: it is a 1RU panel that controls 32 sources and 1 destination. It does
not mount on the front of a router and is used only in a CRSC Network.
The CP1602-CQX is also a special case: it is a 1RU control panel used in conjunction with any of
the CQX routers. This panel has 16 source buttons, 2 “clean and quiet” destination buttons, 6
auxiliary destination buttons, 4 transition type buttons, 3 transition rate buttons, and 7 function
buttons (5 undefined).
The newer CP6464 — a 2RU panel — has an array of 64 buttons that typically switch any of 64
sources to 64 destinations. (These buttons can also be used in other ways.) A specially config-
ured CP6464
— called the CP6401 in CRSC — operates as a single-destination panel having 64
inputs and 1 destination.
Remote Panel Modules
A “remote panel module” is a device that sends control messages to a network of routers (and
receives status messages from the routers in the network). A remote panel module receives take
and lock commands from an attached control panel and must have a control panel attached to
be useful. We say the module is “remote” because it and its control panel can be located apart
from the routers (from a few inches to several hundred meters, subject to cable limitations).
A remote panel is defined as a control panel mounted on a remote panel module.
A remote panel module can be configured to operate (with its mounted control panel) as either
(1) a CRSC remote panel or (2) an NV9000 panel in an NV9000 router control system.
When it is set up for use as a panel in a CRSC network, it is configured in CRSC. When it is set up
for use as an NV9000 panel, it must be configured in NV9000-SE Utilities.
