Spec Sheet: CNXRMC - Room Solution Box

Room Solution Box
Crestron room solution boxes are designed to provide a convenient
one-box signal interface solution for the connection and control of
local room AV devices as part of a complete Crestron Home® AV
distribution system. The CNXRMC is specifically designed as a CAT5
video receiver and control interface, providing baseband outputs for
composite, S-Video, and high-definition component video signals, plus
a variety of IR and serial control ports. The compact CNXRMC normally
installs at the display device (television, plasma, etc.) location and
connects to the head end by just one CAT5E cable and one Cresnet
cable (available as CresCAT®, sold separately). Crestron's CAT5 video
distribution technology permits cable lengths up to 750 feet (500 feet
for component video).
Crestron room solution boxes are designed to provide maximum
flexibility through the use of CAT5 balanced technology. The CAT5
video input port on the CNXRMC receives up to four simultaneous
signals based upon the selected head end source. For instance, a
component signal utilizes the first, second, and third pairs to
transmit the Y, Pb, and Pr components. 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.
Used with the CNX-PVID8X3 or CNX-PVID8X4 video distribution switchers,
the CNXRMC automatically routes the incoming video 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.
For most applications using the CNXRMC, the accompanying audio signal
is distributed to room loudspeakers using a Crestron audio
distribution processor and amplifier. However, a digital audio signal
can be supported by the CNXRMC when fed from a CNX-PVID8X4 switcher.
To maximize the performance of video over CAT5, Crestron employs
adjustable video compensation on each of the three video pairs. The
fourth pair, which is uncompensated, is optimized for digital audio
but may also be suitable for composite video.
Control ports on the CNXRMC include four IR/serial ports and one
bi-directional RS-232 port, providing a powerful interface for control
of numerous devices including video projectors, plasma displays,
televisions, VCRs, DVD players, and more. A single digital input port
is also provided to support the optional CNXRMCS TV current sensor, or
any low-voltage contact closure device.
The CNXRMC functions as a slave device to any 2-Series control system
communicating via the Cresnet control network. Any of Crestron's
touchpanels, keypads, and handheld remotes may be used to provide the
user interface to control the CNXRMC and all connected devices. Adding
an optional CNXRMIRD IR receiver affords cost-effective control from
any Crestron or third-party universal IR remote.
