any of 16 inputs to accept any type of video source. Additional configurations
are made possible through a simple internal jumper modification, permitting
alternate configurations with up to 32 inputs (16 composite + 16 S-Video or
composite) or 24 inputs (8 composite + 8 S-Video/composite + 8 component/
S-Video/composite). Each of these configurations also supports up to 16 coaxial
type digital audio inputs using the fourth matrix level.

Room Solution Boxes—At each remote room location, one of Crestron’s “Room
Solution Boxes” must be connected to the local display device (television,
plasma, etc.) to receive the CAT5 signal and serve as a local switcher. Models
include the CNXRMC, CNXRMCLV, and C2N-DAP8RC (each sold separately). The
room solution box automatically routes the incoming video and digital audio
signals to the appropriate inputs on the display device allowing the viewer to
select any head end video source using a touchpanel, keypad or handheld
remote. Operation is transparent to the end-user with all switching occurring
smoothly under the command of the control system.

Bidirectional Video—Extending the system’s capabilities even further, the
CNXRMCLV and C2N-DAP8RC boxes also support a “return” video signal over a
second CAT5E cable allowing the signal from a local video source to be routed to
the head-end for redistribution to other rooms. To enable this capability, one or
more CNX-PBVR4 balanced video receivers must be included at the head end to
convert the CAT5 return signals to standard RCA unbalanced, allowing each
signal to be connected to any available input on the CNX-PVID8X4.

Alternate Conventional Outputs—In addition to the eight CAT5 outputs, the
CNX-PVID8X4 also includes conventional RCA type unbalanced video outputs to
allow for direct coaxial connections to video display devices. When using the
unbalanced outputs, it should be observed that the CNX-PVID8X4 behaves like
any other matrix or “system” switcher so that a separate output must be used
for each type of video signal. In other words, routing composite, S-Video, and
component signals to a single video projector without using a room solution box
requires a total of three unbalanced video outputs. Also, the unbalanced outputs
are functionally paralleled with the CAT5 outputs so that using a given
unbalanced output might exclude the use of the corresponding CAT5 output for a
given application.

Built-in Video Sensing—Video signal sensing on every input reports the
presence of any active input signal to the control system to provide useful
information about a device’s power status, or to enable auto-switching capability.

Cresnet®Control—Crestron’s video distribution switchers work together with
any 2-Series control system to provide an extensively customizable video
distribution solution. Crestron’s SystemBuilder™ software can make system
programming a quick and simple task for most applications. And for advanced,
highly-custom applications, every matrix crosspoint is independently
programmable through Crestron’s SIMPL™ Windows and SIMPL+

programming software.

Distributing video in a home, office, bar, or restaurant used to mean one of two
things – either modulate every video signal to a TV channel and suffer the low­grade picture quality, or pull a ton of bulky, expensive RG6 cable and wire it all up
to a huge matrix router. Crestron’s CNX-PVID8 video distribution switchers provide
a better solution, combining the flexibility of several matrix routers with the
simplicity of Crestron Home®CAT5 Video Distribution technology. Variable
combinations of video, HDTV, and even digital audio signals are easily configured
to route a rack full of high-end AV sources to television monitors, plasma displays,
and video projectors throughout any facility.

Up to 32 Sources x Up to 32 Rooms—The CNX-PVID8X4 is a versatile video
distribution switcher incorporating four 16 x 8 matrix switchers with Crestron’s
innovative CAT5 balanced interface in a compact 4-space rack mount chassis. The
CNX-PVID8X4 is configurable to handle anywhere from 16 to 32 video inputs and
distribute them to 8 remote room locations up to 750 feet away* over inexpensive
CAT5E cable. Up to four CNX-PVID8X4’s may be combined to handle as many as
32 rooms**. The inputs accept an assortment of composite, S-Video, and high­definition component sources, as well as digital audio.

Crestron Home®CAT5 Balanced Video—Crestron video distribution switchers
are designed to provide maximum flexibility through the use of CAT5 balanced
technology. Each CAT5 output port transmits up to four simultaneous signals
based upon the selected input. For instance, a component signal utilizes the first,
second, and third pairs to transmit the Y, PB, and PRcomponents. Switching to an
S-Video signal then utilizes just the first and second pairs to transmit S-Video’s
Y and C components. Composite utilizes only the first CAT5 pair. The fourth pair is
ordinarily intended for digital audio, but may also be suitable for composite video
in some installations.

To maximize the performance of video over CAT5, adjustable video compensation
is employed on each of the three video pairs while the fourth pair is
uncompensated.

Configurable Inputs—Out of the box, the four wire pairs of each CAT5 output
correspond with the CNX-PVID8X4’s four matrix levels. This configuration allows

**Room outputs are expandable by cascading the inputs of multiple units using standard
RCA interconnect cables. Crestron recommends cascading no more than four (4) units.
However, the actual number of possible units in a system is virtually unlimited, although
additional equipment may be necessary to maintain signal integrity. Contact Crestron for
additional assistance.
