Introduction

About this Manual

This manual discusses how to install, configure, and operate the Extron QSD
204 quad standard decoder and how to operate the optional IR 901 infrared
remote control (part #70-152-01).

Throughout this manual the terms “QSD”, “quad standard decoder”, and
“decoder” are used interchangeably to refer to the same product.

About the QSD 204

What is the QSD 204?

The QSD 204 is a high performance quad standard decoder.
The QSD 204 comes in two models, one of which offers a serial digital interface

(SDI) input connector: QSD 204 (no SDI) and QSD 204 D (with SDI).

Controlling the QSD 204 quad standard decoder

The QSD 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

• The optional IR 901 remote control, which has most of the front panel controls.

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 decoder from a
computer.

Features and Options

Features

Quad standard decoder — The QSD 204 converts interlaced S-video and

composite video signals following either the NTSC 3.58, NTSC 4.43, PAL,
or SECAM video standards, to a non-interlaced output: RGBHV, RGBS,
RGsB, or component video.

Four video inputs —

• Input 1 — One BNC connector on the rear panel accepts composite video.

• Input 2 — Three BNC connectors on the rear panel accepts composite,

component, or S-video.

• Input 3 — A 4-pin DIN connector accepts an S-video signal.

• Input 4 — A 15-pin HD connector accepts an RGBS or RGBcS video

signal.

SDI video input (optional) — One BNC connector on the rear panel accepts SDI

video.

Picture controls — Color, tint (hue), brightness, contrast, centering, and

blanking. The blanking feature will remove unwanted scan lines from the
top or bottom of a displayed image, such as noise and closed captioning.

Four-line adaptive comb filter — Separates the color carrier signal and it’s

harmonics from the video signal to eliminate chroma noise and enables a
projector or monitor to display a clean, clear picture.

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.

QSD 204 • Introduction1-2

Three ways to control the decoder — The decoder’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 QSD.

Autoswitch mode — When autoswitching is enabled, the decoder will

automatically select the highest numbered input which has an input
present.

Sync polarity selection — The output horizontal and vertical sync polarities

may be set for displays which require specific signal polarities.

Serration pulse removal — LCD displays, DLP projectors, and plasma displays

do not require serration pulses to synchronize retracing. The serration
pulse can be stripped from the vertical blanking portion of a signal by
using this feature.

RS-232 configuration — The QSD 204 can be configured by using the Extron

control software for Windows, or by using a third party control system.

Versatile mounting options — The QSD 204 is 1U high, and a half rack wide. It

is rack mountable, or it can be placed on a table or other furniture. An
optional mounting bracket kit will also allow the QSD to be mounted under
a tabletop or desktop. Rubber feet and rack mounting hardware are
included.

Options and accessories

The QSD 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
QSD 204 except the Menu and Next buttons.

• SDI input card — Serial digital interface (SDI) input can be added to the

QSD 204 model by the installation of an SDI input card (part #70-168-01).

Blue mode

To aid in setup of the decoder’s color and tint, the Blue mode can be set from this
submenu to “On” so that only sync and blue video signals will be passed to the
display.

Use either the Adjust horizontal (

) or Adjust vertical ( ) knob to specify this

mode. The default is “Off”.

The Blue mode will be effective for RGB pass-through and YUV input
signals. YC input signals will pass Y, but not C, so the output display will
be black-and-white only.

Autoswitch (Autosw) mode

The Autoswitch mode causes the highest numbered input that has a signal
present, to be automatically selected. For example, if both inputs 1 and 3 have
active input signals, input 3 will be selected.

From this submenu, use either the Adjust horizontal (

) or Adjust vertical ( )

knob to specify this mode as “On” or “Off”. The default is “Off”.

The Autoswitch mode ignores the presence of an SDI input signal, so any
input which is assigned an active SDI signal will not be selected.

Enhanced (Enh) mode

When the Enhanced mode is set “On”, automatic gain control of the video input
signal is enabled. If the input signal level is too weak, the signal gain will be
increased, and if the input signal level is excessive, the signal gain will be
decreased.

From this submenu, use either the Adjust horizontal (

) or Adjust vertical ( )

knob to specify this mode as “On” or “Off”. The default is “Off”.

The Enhanced mode will only be effective on composite and S-video input
signals.

Troubleshooting

This section gives recommendations on what to do if you have problems
operating the QSD 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 sync-

related 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”.

determines that a command is valid, it executes the command and sends a
response to the host device. All responses from the decoder 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.

Decoder-initiated messages

When a local event such as a front panel selection or adjustment takes place, the
QSD 204 decoder responds by sending a message to the host. No response is
required from the host. The decoder-initiated messages are listed here
(underlined).

The QSD 204 sends the copyright message when it first powers on. Vx.xx is the
firmware version number.

X1

C hn
The QSD 204 sends this response when an input is switched. C = both audio
and video were switched.

Error responses

When the decoder receives a valid SIS command, it executes the command and
sends a response to the host device. If the QSD 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.

(where X1 is the input number)

Using the command/response tables

The command/response tables on the next page list valid command ASCII codes,
the decoder’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.

Firmware Upgrade Installation

In some cases the QSD 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 QSD 204 firmware updates must be performed at the
Extron factory.

Follow these steps to replace firmware in the decoder.

1. Disconnect the AC power cord from the QSD 204 to remove power from the

unit.

To prevent electric shock or damage, always unplug the QSD 204
decoder from the AC power source before opening the enclosure.

2. Remove the decoder from the rack or furniture.

3. Remove the cover of the decoder (the top half of the enclosure) by removing

the screws, then lifting the cover straight up.

(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.

5. After you are electrically grounded, the U17 or U38 IC

chip may be removed by grasping it firmly with your
fingers and pulling it out, then continuing to step 8.

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.

8. Align the slots of the new

firmware chip with the
angled corners of the socket
in the same orientation as
the old chip.

9. Gently, but firmly, press the

chip into place in the socket.

10. Replace the top cover on the QSD 204 decoder, and fasten it with the screws

that were removed in step 3.

Serial Digital Interface (SDI) Card Installation

The optional SDI card may be installed in the decoder 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 QSD 204.

1. Disconnect the AC power cord from the QSD 204 to remove power from the

unit.

To prevent electric shock, always unplug the QSD 204 decoder from the
AC power source before opening the enclosure.

2. Remove the decoder from the rack or furniture.

3. Remove the cover of the decoder (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
decoder. Doing so could damage the decoder. 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).
