Introduction
About this Manual
This manual discusses how to install, configure, and operate the Extron DVS 204
digital video scaler and how to operate the optional IR 901 infrared remote
control (part #70-152-01).
Throughout this manual the terms “DVS”, “digital video scaler”, and “scaler”
are used interchangeably to refer to the same product.
About the DVS 204
What is the DVS 204?
The DVS is a series of high performance digital video scalers that offers 56
output rates, including HDTV, and provides scaling solutions for boardrooms,
conference rooms, and home theaters, as well as rental and staging applications.
The scalers come in four models, two of which offer a serial digital interface (SDI)
input connector: DVS 204 (no SDI), DVS 204 D (SDI), DVS 204 12V (12 volt
external power supply, no SDI), and DVS 204 D 12V (12 volt external power
supply, SDI).
To enable superior scaling performance, the DVS 204 features several of Extron’s
patented and patent-pending technologies, including Dynamic Motion
Interpolation (DMI™) technology, and 3:2 and 2:2 pulldown detection. DMI is
an advanced motion detection and compensation method that enables image
enhancement with no loss of image fidelity.
The DVS 204 scales composite video, S-video, and component video up to
computer-video (RGBHV/RGBS/RGsB) or HD component, which can be output
to two display devices via individually buffered BNC and 15-pin HD connectors.
Controlling the DVS 204 digital video scaler
The DVS 204 can be controlled using one or more of the following methods:
• The front panel controls.
• A computer, a touch screen panel, or any other device that can send and
receive the serial communications through the RS-232 port. Extron’s
Simple Instruction Set (SIS™) is a set of simple keystroke commands that
can be used with any such devices, and Extron’s control software for
Windows provides a graphical interface for controlling the scaler from a
computer.
• The optional IR 901 remote control, which has most of the front panel controls.
Features and Options
Features
Four video inputs
• Input 1 — One BNC connector on the rear panel accepts composite video.
• Input 2 — Three BNC connectors on the rear panel accept composite,
component, or S-video.
• Inputs 3 — One 4-pin DIN connector accepts an S-video signal.
• Input 4 — One 15-pin HD connector accepts an RGB pass-through
(RGBHV, RGBS, RGsB), RGBS, or RGBcvS video signal.
SDI video input (optional) — One BNC connector on the rear panel accepts SDI
video.
1-2
DVS 204 • Introduction
Buffered video outputs — Six rear-panel BNC connectors and one VGA-type
15-pin HD connector provide connections for RGB output. Both outputs
(the BNCs or the 15-pin HD connector) are active at all times for
simultaneous output.
Three ways to control the scaler — The scaler’s front panel, a computer or other
RS-232 control device, or the optional IR 901 remote control can all be used
to control the scaler.
Scaled outputs — The DVS 204 offers 59 different output rates.
RS-232 configuration — The DVS 204 can be configured by using the Extron
control software for Windows, or by using a third party control system.
Accu-RATE Frame Lock™ — The Extron Accu-RATE Frame Lock™ eliminates
artifacts from scaled motion video by eliminating frame rate conversion. It
locks the output frame rate to the input frame rate of the active input. The
result is a switching system that eliminates image tears and other artifacts
from motion video.
Dynamic Motion Interpolation™ (DMI™) — This video processing technique is
an advanced motion prediction and compensation method that treats
motion content and still content with different algorithms to yield high
fidelity images.
3:2 pulldown detection for NTSC and 2:2 film detection for PAL video sources
— These advanced film mode processing features help maximize image
detail and sharpness for video sources that originated from film. When
film is converted to NTSC video, the film frame rate has to be matched to
the video frame rate in a process called 3:2 pulldown. Jaggies and other
image artifacts can result if conventional deinterlacing techniques are used
on film-source video. The DVS 204’s advanced film mode processing
recognizes signals that originated from film. The DVS 204 then applies
video processing algorithms that optimize the conversion of video that was
made with the 3:2 pulldown process. This results in richly detailed images
with sharply defined lines. A similar process is used for PAL film-source
video.
Versatile mounting options — The DVS 204 is 1U high, and a half rack wide. It
is rack mountable, or it can be placed on a table or other furniture. Rubber
feet are included.
Options and accessories
The DVS 204’s optional equipment includes:
• IR 901 remote control — Extron’s IR 901 (part #70-152-01) is an infrared
remote control which replicates all of the front panel controls of the
DVS 204 except the Menu and Next buttons.
• SDI input card — Serial digital interface (SDI) input can be added to the
DVS 204 model by the installation of an SDI input card (part #70-168-01).
• Rack shelf mounting kit — The 1U high, half rack width DVS 204 can be rack
mounted using the rack shelf mounting kit (part #60-190-01).

Outputs 7 and 8 are both buffered and can be connected simultaneously
to two different displays. For RGB inputs, the output signal’s sync format is
based on the format of the incoming RGB signal. For all other types of
inputs, the user selects the output sync format. The sync format will be the
same for both outputs.
RGB pass-through — An RGB pass-through signal with composite sync
(“RGB” is selected for input 4; see the Input Configuration section in this
chapter) will always output composite sync through the “H” BNC output
connector, as shown in the following illustration.
If both an RGB pass-through signal with composite sync and a scaled video
input (1-3) are output as RGBS, the H Format must be set to “HV”
(composite sync). This will cause the scaled video input to output composite
sync on the same connector (the “H” BNC) as the pass-through signal
instead of the “S” BNC. See the H Format section in this chapter.
For scaled inputs on input 4 (RGBS or RGBcvS), the H Format will not
have to be set to “HV” since those inputs will be output like inputs 1-3, as
shown in the previous connection diagram.

To select a different input number using a contact closure device,
momentarily short the pin for the desired input number to logic ground

Optimizing the System for a DVD
For optimal performance, follow the steps in this section in order when setting
up the DVS 204 for a DVD.
Setting up a DVD source
To get the best results when using a DVD as a video source, Extron recommends
that the DVD player itself be setup to output an aspect ratio of 16:9 and not 4:3.
Because all DVDs are mastered as 16:9, having them set up for anything else will
cause the player to internally scale and compress the signal. This scaling/
compression by the DVD player will defeat the advantage of having 3:2
pulldown detection in the DVS 204.
All sizing adjustments to correct aspect ratio should be done using the DVS 204.
To change the output aspect ratio of most DVD players,
2-8
1.
Enter the DVD player’s Setup or Action menu while the disc is stopped.
2.
Select a 16:9 aspect ratio.
DVS 204 • Installation and Operation
Menus, Configuration, and Adjustments
Scaler configuration and adjustments can be performed by using the Windowsbased control program (see chapter three for details) or by using the front panel
controls and the menus that are displayed on the DVS 204’s LCD screen. These
menus are used primarily when the scaler is first set up.
Moving through menus by using front panel controls
Menu button — Press the Menu button to activate menus and to scroll to the six
main menus.
Next button — Press the Next button to move between the submenus of a
selected main menu. Pressing the Next button during input configuration
causes the current input’s number and format type to be displayed on the
LCD
Adjust ( , ) knobs — In configuration mode, rotate the Adjust horizontal ( )
knob and Adjust vertical ( ) knob to scroll through submenu options and to
make adjustment selections. Refer to the flowcharts in this chapter and to
specific sections for explanations on knob adjustments.
Image adjustment buttons: Col/Tnt, (color/tint) Brt/Cont (brightness/contrast),
Size, and Center — When one of these buttons is pressed successively, the
corresponding image adjustment menu appears on the LCD screen.
Adjustments can then be made by rotating the Adjust horizontal ( ) knob
or the Adjust vertical ( ) knob. Settings and adjustments are stored in
nonvolatile memory.
Menu overview
The default menus appear on the LCD when no adjustments are actively being
made. They cycle between the screen showing the model of the scaler (DVS 204

The absence of any saved presets will not display the “Input #X Memory Y”
LCD message for the absent preset.
The presets are specific to a selected output rate. If the output rate is
subsequently changed, the previously saved preset will have no effect on the
video output. However, if the original output rate is later restored for a
saved preset, the preset will again apply to that output rate.

Troubleshooting
This section gives recommendations on what to do if you have problems
operating the DVS 204, and it provides examples and descriptions for some
image problems you might encounter.
The following are some tips to help you in troubleshooting.
1.
Some symptoms may resemble others, so you may want to look through all
of the examples before attempting to solve the problem.
2.
Be prepared to backtrack in case the action taken doesn’t solve the problem.
3.
It may help to keep notes and sketches in case the troubleshooting process
gets lengthy. This will also give you something to discuss if you call for
technical support.
4.
Try simplifying the system by eliminating components that may have
introduced the problem or made it more complicated.
5.
For sync-related problems: Portable digital projectors are designed to
operate close to the video source. Sync problems may result from using
long cables or from improper termination. A sync adapter, such as Extron’s
ASTA (active sync termination adapter), may help solve these problems.
6.
For LCD and DLP projectors and plasma displays: In addition to the syncrelated information above, check the user’s manual that came with the
projector for troubleshooting tips, as well as for settings and adjustments.
Each manufacturer may have its own terms, so look for terms like “auto
setup”, “auto sync”, “pixel phase”, and “tracking”.
Operating problems
The table below shows some common operating problems and their solutions.
Problem
Cause
Solution
No image appears.
The input signal is
incompatible.
Attach an input device that is
compatible with NTSC 3.58,
NTSC 4.43, PAL, or SECAM.

Serial Communication
The DVS 204 can be remotely controlled via a host computer or other device
(such as a control system) attached to the rear panel Remote connector. The
control device (host) can use either Extron’s Simple Instruction Set (SIS)
commands or the graphical control program for Windows.
The scaler uses a protocol of 9600 baud, 1 stop bit, no parity, and no flow control.
The rear panel RS-232 9-pin D connector has the following pin assignments:

RS-232 Programmer’s Guide
Host-to-scaler communications
SIS commands consist of one or more characters per field. No special characters
are required to begin or end a command sequence. When the DVS 204
determines that a command is valid, it executes the command and sends a
response to the host device. All responses from the scaler 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.
It is also possible to send several SIS commands back-to-back in sequence.
Scaler-initiated messages
When a local event such as a front panel selection or adjustment takes place, the
DVS 204 scaler responds by sending a message to the host. No response is
required from the host. The scaler-initiated messages are listed here
(underlined).
(C) Copyright 2002, Extron Electronics, DVS 204, Vx.xx
The DVS 204 sends the copyright message when it first powers on. Vx.xx is the
firmware version number.
C hn X1
(where X1 is the input number)
The DVS 204 sends this response when an input is switched.
Error responses
When the scaler receives a valid SIS command, it executes the command and
sends a response to the host device. If the DVS 204 is unable to execute the
command because the command is invalid or it contains invalid parameters, it
returns an error response to the host.
The error response codes and their descriptions are as follows:
E01 – Invalid input channel number (the number is too large)
E10 – Invalid command
E11 – Invalid preset number
E13 – Invalid value (the number is out of range/too large)
E17 – Illegal command for this signal type.

Using the command/response tables
The command/response tables on the next page list valid command ASCII codes,
the scaler’s responses to the host, and a description of the command’s function
or the results of executing the command. Upper and lower case characters may be
used interchangeably in the command field.
The ASCII to HEX conversion table at left is for use with the

Control Software for Windows
The included Extron DVS 204 Control Program for Windows offers another way
to control the DVS 204 via RS-232 connection in addition to the Simple
Instruction Set commands. The control program’s graphical interface includes
the same functions as those on the scaler’s front panel and some additional
features that are only available through the Windows-based software.
The control software is compatible with Windows 95/98, Windows NT, and
Windows 2000. Extron’s DVS 204 Control Program is included with the scaler,
and updates can be downloaded from the Extron Web site
(http://www.extron.com).
Installing the software
The control program is contained on a set of 3.5-inch diskettes, and it requires
approximately 2 MB (megabytes) of hard disk space.
To install the software on the hard drive:
1.
Run SETUP.EXE from the floppy disk.
2.
Follow the instructions that appear on the screen.
By default the installation creates a C:\DVS 204 directory, and it places two icons
(DVS 204 Control Pgm and DVS 204 Help) into a group or folder named “Extron
Electronics”.
Using the control program
Many items found in the DVS 204 Control Program are also accessible via front
panel controls and the LCD menus described in chapter two. Refer to chapter
two for details on features and settings. The DVS 204 Help Program provides
information on settings and on how to use the control program itself. Some
features, including the miscellaneous options, are only available via this control
program. These features are described in the sections of this chapter that
correspond to the parts of the control program where the features are found.
3-8
1.
To run the control program, double-click on the DVS 204 Control Pgm icon
in the Extron Electronics group or folder. The Comm menu appears on the
screen.
2.
Click on the comm port that is connected to the DVS 204’s RS-232 port.
The Extron DVS 204 Control Program windows appear.

Firmware Upgrade Installation
In some cases, the DVS 204’s firmware may require replacement with an updated
version. There are three user-replaceable firmware chips: U41 — the main
microcontroller, U38, and U17. The numbers are printed on the circuit board. We
recommend that you send the unit to Extron for service and updates.
Changes to firmware must be performed by authorized service personnel
only. Some DVS 204 firmware updates must be performed at the
Extron factory.
Follow these steps to replace firmware in the scaler.
Disconnect the AC or 12 VDC power cord from the DVS 204 to remove
power from the unit.
1.
To prevent electric shock or damage, always unplug the DVS 204 scaler
from the AC or DC power source before opening the enclosure.
2.
Remove the scaler from the rack or furniture.
3.
Remove the cover of the scaler (the top half of the enclosure) by removing
the screws, then lifting the cover straight up.

Do not touch any switches or other electronic components inside the
scaler. Doing so could damage the scaler. Electrostatic discharge (ESD)
can damage IC chips even though you cannot feel it. You must be
electrically grounded before proceeding with firmware replacement. A
grounding wrist strap is recommended.
4.
Locate the firmware chip(s) to be replaced on the circuit board, as shown in
the following illustration.

Removal of the U41 IC chip requires a PLCC IC puller
tool. To remove the U41 chip, align the hooks of a
PLCC IC puller tool with the slots located in opposite
ends of the U41 firmware chip.
6.
Insert the hooks into the slots, and squeeze the tool
gently to grasp the chip.
7.
Pull the chip straight out
of the socket, and set it
aside.

For U17 and U38, align
the notch of the new
firmware chip with the
notch of the socket in the
same orientation as the old chip.
For U41, align the angled corner of the firmware chip with the angled
corner of the socket.

Serial Digital Interface (SDI) Card Installation
The optional SDI card may be installed in the scaler if it does not already have an
input for a serial digital interface signal. We recommend that you send the unit
in to Extron for service and updates.
Changes to electronic components must be performed by authorized
service personnel only.
Follow these steps to install an SDI card in the DVS 204.
1.
Disconnect the AC or DC power cord from the DVS 204 to remove power
from the unit.
To prevent electric shock, always unplug the DVS 204 scaler from the
AC power source before opening the enclosure.
2.
Remove the scaler from the rack or furniture.
3.
Remove the cover of the scaler (the top half of the enclosure) by removing
the screws, then lifting the cover straight up. See the top cover removal
diagram in the “Firmware Upgrade Installation” section.
Do not touch any switches or other electronic components inside the
scaler. Doing so could damage the scaler. Electrostatic discharge (ESD)
can damage IC chips even though you cannot feel it. You must be
electrically grounded before proceeding with any electronic component
replacement. A grounding wrist strap is recommended.
4.
Locate the SDI card standoff located near the middle rear portion of the
main circuit board (looking from above with the front panel nearest to you).
