CR Series Compact Routers
Routers
All CR Series routers except machine control routers have
connectors for bi-level or tri-level video reference (sync) sig-
nal and will switch according to SMPTE RP168-2002.
We recommend using a video reference. The video reference
is loop-through: you can pass the video reference on to other
routers or terminate the reference at any point.
Each router has two power inputs for redundancy, a ground-
ing lug, an RS-485/422 automation port, and an Ethernet
port.
Each
analog audio
router has DB25 connectors for I/O. See Fig-
ure 7. Each
machine control
router has RJ-45 connectors for I/
O. See Figure 8. Each 64×64 router has DIN 1.0/2.3 coax con-
nectors for I/O. See Figure 9. All o
ther
routers have 75
Ω
BNC
connectors for I/O. See Figure 6.
Each router saves its current state (crosspoint connections,
locks, etc.) in non-volatile memory.
“3Gig” Video Routers
The 3Gig video routers (including the CR6464-3Gig) support
2.97
Gb/s operation and several HD and SD data rates. They
support DVB-ASI.
HD Video Routers
The HD routers are “SWB” (super wide band) routers. They
support a wide range of SD and HD serial data rates. They sup-
port DVB-ASI.
The HD routers are available in less expensive non-reclocking
models, such as the CR1616-HD-NR. However, the reclocking
models give better performance and can driver longer cable
runs.
SD Video Routers
The SD routers support a wide range of SD serial data rates.
They support DVB-ASI.
The SD routers are available in less expensive non-reclocking
models, such as the CR3204-SD-NR. However, the reclocking
models give better performance in noisy environments.
AES Audio Routers
The AES routers (including the CR6464-AES) support AE3id
audio. The AES routers will switch in sync with a video refer-
ence if one is available and will free-run if no reference is
available. If a video reference is not present, the router is
asynchronous and it passes input signals straight through
without any processing.
Analog Video Routers
The analog video routers switch NTSC (525i) and PAL (625i)
formats.
Analog Audio Routers
The analog audio routers switch analog audio signals. They
pass the signal straight through and do no internal process-
ing.
The CR1616-AA switches 16 stereo pairs. The CR0808-AA
switches 16 stereo pairs. The CR3232-AA switches 32 stereo
pairs. The CR1604-AA switches 16 input pairs to 4 output
pairs. The CR3204-AA switches 32 input pairs to 4 output
pairs. The analog routers do not perform mono switching.
Machine Control Routers
The CR16-PR and CR32-PR routers (i.e., port routers) switch
machine control streams or serial data streams up to 1Mb/s.
The CR16-PR has 16 ports and the CR32-PR has 32. The ports
are bidirectional, RS-422. Connections are point-to-point.
Machine control ports can be configured in several ways.
Software is required for port configuration.
CQX Routers
There are 3 “clean and quiet” (CQX) routers that switch 3Gig,
HD, and SD video, respectively, with smooth transitions in
video and audio.
The 3Gig router switches signals at either SMPTE 425 level A
(HD progressive) or SMPT 425 level B (2 HD interlaced signals
in one stream).
These routers support 4 selectable transition types: cut,
V-fade, cut-fade, and fade-cut. They support 3 selectable tran-
sition rates: slow (3 seconds), medium (2 seconds), and fast (1
second).
A CQX router has 2 “clean and quiet” outputs and 6 normal
outputs. Internally there is a two-channel mixer that com-
bines 2 of the router’s 16 inputs for each clean and quiet
channel.
Two bypass inputs can feed the clean and quiet outputs if
power is disconnected from the router.
Operating Modes
CR Series routers can be used in 5 general modes:
•
A stand-alone router, with an attached control panel.
•
A stand-alone network of routers and remote panels.
•
A “CRSC” network of routers and remote panels.
•
An NV9000 network: one or more compact routers con-
trolled by an NV9000 router control system. The NV9000
system may also include routers, CR Series remote panels,
and NV96
xx
control panels.
•
A CQX router and a CQX control panel.
These modes determine the behavior of CR Series products
and affect the meaning of CR Series features.
For example, routers and control panels in a CRSC network
are highly configurable. In stand-alone modes, they are not
configurable. There are many other significant differences.
