Introduction
About the CD 900
The Extron CD 900 is a 2-input, switching, high-resolution
quad-standard video decoder, with a three-line adaptive comb
filter. It converts NTSC, PAL, or SECAM standard interlaced Svideo or composite video signal to a non-interlaced output in
one of four formats:
• RGBHV
• RGBS
• RGsB
• Component video (Y, P
This allows the connection of devices, such as a DVD player; a
VHS, S-VHS, or Super 8 tape deck; a camcorder; or a television
receiver, to a presentation device such as a data monitor or large
screen projector (figure 1).
CD 900
Figure 1 — Typical CD 900 application
Features
Quad-standard decoder— The CD 900 converts interlaced
S-video and composite video signals that are in one of the
four international analog video 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— The CD 900 uses a three-line
adaptive comb filter to separate the color carrier signal
and its harmonics from the rest of the video signal. Comb

filtering yields an RGB or component video signal that is
free of noise, and produces 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 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.
RGB or component video outputs— The CD 900 decoder
outputs either RGB or component video. Select the
output using a rear panel DIP switch.
RGB video outputs— When selected for RGB video, the
decoder outputs signals with either separate
horizontal and vertical sync signals (RGBHV),
composite sync (RGBS), or sync on green (RGsB).
Select the sync format using a rear panel 3-position
switch.
Component video output— When selected for
component video, the decoder outputs Y, P
B, PR
component video.
RS-232 control — An RS-232 port allows the CD 900 to be
controlled by a remote computer or other host. RS-232
control uses Extron’s Simple Instruction Set™ (SIS™).
Contact closure— The RS-232 connector may also be used by a
contact closure keypad to select inputs.
Simple Instruction Set — The Simple Instruction Set program
lets a host computer control the CD 900 with simple
commands.
Windows control software— Extron’s Windows-based control
software provides a graphic way to set up and control the
CD 900 with an on-screen control panel. It allows the
operator to remotely select inputs, make picture
adjustments, and store settings for future use.
Auto-switching — When set for auto-switch mode, the CD 900
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.

Introduction, cont’d
Serration pulse removal— LCD displays, DLP projectors, and
plasma displays don’t need pulses to synchronize
retracing. A r ear panel DIP switch causes the serration
pulses to be stripped from the vertical blanking portion of
a signal.
Rack mount option— The CD 900 is 1U high and half-rack
wide. It can be installed on a standard rack shelf by using
an Extron 1U Shelf Rack, part # 60-190-01.
Auto-switching power supply— An internal power supply
with an IEC connector makes power cord connection easy.
The power supply can be used internationally with any
power input from 110 VAC to 240 VAC at 50 or 60 Hz and
adapts automatically to the input type.

Figure 10 — RS-232/Remote connector pinout
The RS-232 protocol of the rear panel RS-232/Remote connector
is 9600 baud, 1 stop bit, no parity, and no flow control. When
the CD 900 receives an RS-232 communication, the front panel
Min LED blinks once, then the Max LED blinks. (In Executive
mode, the LEDs are on and do not blink.) The connector has the
following pin assignments:
When a local event, such as a front panel operation or error
condition, occurs, the CD 900 responds by sending a message to
the host. The CD 900-initiated messages are listed below:
(C) Copyright 1999, Extron Electronics CD 900, Vx.xx
The CD 900 issues the copyright message when it first powers
on. Vx.xx is the firmware version number.
Reconfig
The CD 900 initiates this message when there is a change in the
selected input or any picture control setting.
Factory Defaults Reset on Channel #1
Factory Defaults Reset on Channel #2
These CD 900-initiated message indicate an RS-232
communication error. Possible causes include an RS-232
connection or baud rate problem.

Simple Instruction Set Control
Host-to-interface communications
SIS commands consist of one or more characters per field. No
special characters are required to begin or end a command
character sequence. When a command is valid, the CD 900
executes the command and sends a response to the host device.
All responses from the CD 900 to the host end with a carriage
return and a line feed (CR/LF = ), which signals the end of
the response character string. A string is one or more characters.
CD 900 Decoder • RS-232/Remote Control
Error responses
When the CD 900 receives a valid SIS command, it executes the
command and sends a response to the host device. If the
CD 900 is unable to execute the command because the
command is invalid or it contains invalid parameters, the
CD 900 returns an error response to the host. The error response
codes are:

Windows-Based Program Control
The Signal Enhancement Control Program is Windows
compatible and provides remote control of the following:
• Input selection
• Video adjustments
Installing the software
The program is contained on a single 3.5” diskette and can be
run from the floppy drive, or it can be installed and run from
the hard drive.
To install the software on the hard drive, run setup.exe from the
floppy disk and follow the screen instructions.
By default, the Windows installation creates a C:\S_ENHANC
folder and places two icons (Signal Enhancement Products
Control Program and Signal Enhancement Products Help) into a
group named “Extron Electronics”.
Using the software
1.To run the software, double click on the Signal
Enhancement Products Control Program icon
in the Extron Electronics program group.
2.Click on the comm port that is connected to the CD 900’s
RS-232 port.
3.Extron’s Signal Enhancement Products Control Program
window (figure 11) displays the current input selection by
marking it with a red dot and shows both slider controls
and numeric values for the picture controls.
Figure 11 — Signal enhancement program
window
Using the help system
For information about program features, you can access the help
program in any of the following ways:
• From the Extron Electronics program group, double-click on
the Signal Enhancement Products Help icon.
•From within the Windows-based signal
enhancement program, click on the Help entry on the task
bar.
• From within the Windows-based signal enhancement
program, press the F1 key.
Contact Closure Control
The RS-232 connector provides a way to select an input to the
CD 900 using a remote contact closure device and indicate the
selected input on the contact closure device. Contact closure
control uses pins on the RS-232/Remote connector that are not
used by the RS-232 interface. The contact closure pin
assignments are shown in the table on page 4-2.
To select a different input number using a contact closure
device, momentarily short the pin for the desired input number
to logic ground (pin 5). To force one of the two inputs to be
always selected, leave the short to logic ground in place. The
short overrides front panel input selections.
The tally pins can be used for remote indication of the selected
input. Tally #1 or tally #2 indicate the selected input number
with a logic low (0 volts). If an input is not selected, the
associated tally pin is at logic high (5 volts).
Figure 12 can be used as a guide to design and build indicator
circuits for the tally pins. Since there is no voltage source on the
RS-232 connector, an external voltage source is required.
