standard decoder and on how to operate and configure it.
About the CD 800
The CD 800 is a high-resolution, quad-standard video
decoder with a three-line adaptive comb filter. It converts
NTSC, PAL, or SECAM standard interlaced S-video or
composite video signals to non-interlaced RGBHV or RGBS
video output. This allows the connection of devices such as
a VCR, S-VHS, or Super 8 tape deck, camcorder, or
television receiver to a presentation device such as a data
monitor or large screen projector.
Features
Quad-standard decoder — The CD 800 converts interlaced
S-video and composite video signals that use
international analog standards. These include
NTSC 3.58, NTSC 4.43, PAL, and SECAM. Front
panel LEDs indicate which standard is active.
Three-line adaptive comb filter — Comb filtering yields an
RGB signal that is free of noise and gives a clean,
clear picture.
Picture controls — Color, tint (hue), contrast (white level),
and horizontal shift (centering) features are adjusted
using knobs on the front panel or through the RS-232
control program.
Automatic memory — Picture control settings are
automatically saved for composite video (input 1)
and for S-video (input 2) in two separate memories.
The settings are recalled automatically when an input
is selected.
RGBHV, RGBS or RGsB outputs — The CD 800 decoder
outputs RGB signals with either separate horizontal
and vertical sync signals (RGBHV), composite sync
(RGBS), or sync on green (RGsB).
RS-232 control — An RS-232 port allows the CD 800 to be
controlled by a remote computer or other host.
RS-232 control uses Extron’s Simple Instruction Set™
(SIS™).
Contact closure — Inputs can be selected via a contact
closure keypad connected to the RS-232 port.

Simple Instruction Set — The SIS program lets a host
computer control the CD 800 with simple commands.
Control software for Windows ® — Extron’s Windows-
based control software provides a graphical way to
set up and control the CD 800 with an on-screen
control panel. It provides remote selection of inputs
and picture adjustments, and stores settings for
future use.
Auto-switching — When set for auto-switch mode, the
CD 800 automatically detects active incoming sync
signals and selects (switches to) that input. If both
inputs are active, the default is input #2 (S-video).
Sync polarity output selection — Two rear panel DIP
switches allow the polarity of horizontal and vertical
sync signals to be set separately. This allows for
compatibility with most display devices/projectors.
Serration pulse removal — LCD, DLP, and plasma display
devices don’t need pulses to synchronize retracing.
A rear panel DIP switch causes the serration pulses to
be stripped from the vertical blanking portion of a
signal.
Rack mount option — The CD 800 is 1U high and half-rack
wide. It can be installed on a standard rack shelf by
using an Extron 1U Shelf Rack, P/N 60-190-01.
Auto-switching power supply — An internal power
supply with an IEC connector makes power cord
connection easy. It can be used internationally with
any power input from 110VAC to 240VAC at 50 or 60
Hz. It adapts automatically to the input type.
