Routers
The 16×16 routers can switch any of 16 inputs to any of 16 outputs and the 32×32 routers can
switch any of 32 inputs to any of 32 outputs. The 8×8 routers switch 8 inputs to 8 outputs. The
16×4 routers switch 16 inputs to 4 outputs. The 32×4 routers switch 32 inputs to 4 outputs.
Machine Control Routers
With the exception of the machine control routers (CR16-PR and CR32-PR), 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 RS-422 and bidirectional, typically with
commands in one direction and responses in the other direction.)
“Clean and Quiet” Routers
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. There are no 2RU
clean and quiet routers at present. The CQX routers also provide a GPIO connector, supporting
16 inputs and 4 outputs. The inputs each select one of the video inputs for CQ output 1 and the
outputs signal alarms and status. See
GPIO Connections for CQX Digital Video Routers on
page 129 for details.
CR6400 Routers
The CR6400 family is a unique subset of the Grass Valley’s CR series of compact routers: the
family’s routers have a larger switching matrix (64×64) and modular construction. The family
includes two routers and a control panel.
• CR6464-3Gig — a 2RU 64×64 video router
• CR6464-AES — a 2RU 64×64 AES router
• CP6464 — a 2RU 64×64 control panel
The CR6400 routers have removable control cards, removable crosspoint cards, and a removable
fan tray. Because they are removable, they are field-serviceable.
Each router has 4 removable I/O cards. If a router is populated with one or more AES cards, it is
considered a CR6464-AES. If a router is populated with one or more 3Gig cards, it is considered a
CR6464-3Gig. If a router has no I/O cards, it is considered to be of “undefined” type.
The CR6400 family products work together may be mixed (on the same subnet) with other CR
Series routers and panels.
Control Panels
A CR Series control panel mounts on the front of a router or on the front of a remote panel
module and provides direct visual and tactile control of the router or routers connected to the
remote panel module. (You can install or uninstall one easily in a few seconds.) However, any of
