3.1 About HDMI
High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital1
audio/video interface, widely supported in the entertainment and home cinema
industry. It delivers the maximum high-definition image and sound quality in use
today. In particular, HDMI2:
Provides a simple3 interface between any audio/video source, such as a set-top
box, DVD player, or A/V receiver and video monitor, such as a digital flat LCD
/ plasma television (DTV), over a single lengthy4 cable
Supports standard, enhanced, high-definition video, and multi-channel digital
audio5 on a single cable
Transmits all ATSC HDTV standards and supports 8-channel digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements
1 Ensuring an all-digital rendering of video without the losses associated with analog interfaces and their unnecessary digitalto-analog conversions
2 HDMI, the HDMI logo and High-Definition Multimedia Interface are trademarks or registered trademarks of HDMI
licensing LLC
3 With video and multi-channel audio combined into a single cable, the cost, complexity, and confusion of multiple cables
currently used in A/V systems is reduced
4 HDMI technology has been designed to use standard copper cable construction at up to 15m
5 HDMI supports multiple audio formats, from standard stereo to multi-channel surround-sound. HDMI has the capacity to
support Dolby 5.1 audio and high-resolution audio formats
3
Your Presentation Switcher / Scaler
Benefits consumers by providing superior, uncompressed digital video quality
via a single cable1, and user-friendly connector
Is backward-compatible with DVI (Digital Visual Interface)
Supports two-way communication between the video source (such as a DVD
player) and the digital television, enabling new functionality such as automatic
configuration and one-button play
Has the capacity to support existing high-definition video formats (720p, 1080i,
and 1080p/60), standard definition formats such as NTSC or PAL, as well as
480p and 576p
3.2 Recommendations for Best Performance
To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise-levels
(often associated with low quality cables)
Avoid interference from neighboring electrical appliances and position your
CSC-7850 away from moisture, excessive sunlight and dust

Installing in a Rack
5 Installing in a Rack
This section describes what to do before installing in a rack and how to rack
mount.
Before Installing in a Rack
Before installing in a rack, be sure that the environment is
within the recommended range:
Operating temperature range +5º to +45º C (41º to 113º F)
Operating humidity range 10 to 90% RHL, non-condensing
Storage temperature range -20º to +70º C (-4º to 158º F)
Storage humidity range 5 to 95% RHL, non-condensing
To rack-mount a machine:
1. Attach both ear brackets to the
How to Rack Mount
machine. To do so, remove the
screws from each side of the
machine (3 on each side), and
replace those screws through the
ear brackets.
When installing on a 19" rack, avoid hazards by taking
CAUTION!!
care that:
1. It is located within the recommended environmental
conditions, as the operating ambient temperature of a
closed or multi unit rack assembly may exceed the
room ambient temperature.
2. Once rack mounted, enough air will still flow around
the machine.
3. The machine is placed straight in the correct
horizontal position.
4. You do not overload the circuit(s). When connecting
the machine to the supply circuit, overloading the
circuits might have a detrimental effect on overcurrent
protection and supply wiring. Refer to the appropriate
nameplate ratings for information. For example, for
fuse replacement, see the value printed on the
product label.
5. The machine is earthed (grounded) in a reliable way
and is connected only to an electricity socket with
grounding. Pay particular attention to situations where
electricity is supplied indirectly (when the power cord
is not plugged directly into the socket in the wall), for
example, when using an extension cable or a power
strip, and that you use only the power cord that is
supplied with the machine.
2. Place the ears of the machine
against the rack rails, and insert the
proper screws (not provided)
through each of the four holes in the
rack ears.
Note that:
In some models, the front panel
may feature built-in rack ears
Detachable rack ears can be
removed for desktop use
Always mount the machine in the
rack before you attach any cables
or connect the machine to the
power
