Introduction
About the Scaler
Extron’s DVS 150 digital video scaler allows analog video signals (composite video,
S-video, and component video) to be displayed on a device with a fixed resolution
and aspect ratio, such as an LCD (liquid crystal display) projector, DLP (digital
light processing) projector, or plasma display.
The DVS 150 includes a 15-pin HD RGB pass-through connector for RGB input.
Video signals coming into the scaler from this connector are not scaled. Instead,
they are passed directly to the outputs.
Features
• Autosave — Automatically stores adjustments and uses the control settings
associated with the selected input.
• Autoswitch mode — Automatically selects the active input device. If more than
one input device is on, the device with the highest video quality is selected.
• Blanking — Allows noise or unwanted information, such as tape head switching
and closed captioning, to be eliminated from the top and bottom of the
display.
• Dual output connectors — Allow you to connect and run two output devices
simultaneously.
• Executive mode — Locks out all front-panel image adjustment functions except
input selection. When executive mode is active, all image adjustments are
available through RS-232 commands.
• Freeze mode — Locks the output display to the current image.
• Inputs — Includes three BNC connectors for component video, one BNC
connector for composite video, and one 4-pin mini-DIN connector for
S-video. The DVS 150 also includes one 15-pin HD connector for RGB pass-
through input.
• Multiple control methods — Allow you to make adjustments by pressing a
button on the front panel, choosing options from a menu, sending an RS-232
command from a computer, or using a remote contact closure control.
• Outputs — Outputs video as RGB, RGsB, RGBS, and RGBHV. BNC connectors
and a 15-pin HD connector are provided.
• Output resolutions — Supports the following output resolutions:
•

DVS 150 Introduction
• Power supply — Includes an internal, 100-240VAC, 50/60 Hz, auto-switchable
power supply.
• Precise image processing — Provides the latest in motion compensation, which
produces motion images that are free of jaggies; a three-line adaptive comb filter,
which eliminates chroma crawl; and a quad standard decoder, which ensures
compatibility with NTSC (National Television Standards Committee) 3.58,
NTSC 4.43, SECAM (sequential couleur avec mémoire), and PAL (phase
alternate line) video standards.
• Software-based configuration — Allows you to configure the scaler through
menu controls, simplifying installation.
• Switchable sync polarities — Allow you to manually set the horizontal and
vertical sync polarities, to allow the output device to store DVS input as a
unique input.

Freeze mode
Freeze mode locks the output display to the current image. Freeze mode can be
activated only by issuing an RS-232 command (see chapter 4 for
more information). If freeze mode is activated, the LCD screen
displays the message displayed at the left.
IMAGE
FROZEN
If input 4 (RGB pass-through) is selected, you cannot activate freeze mode.
You can deactivate freeze mode in the following ways:
• By issuing another RS-232 command
• By pressing the input button
• Automatically, if the scaler is in autoswitch mode and the input source changes.
Executive mode
Executive mode limits the number of operations available from the front panel.
This is useful for situations in which many end users operate the scaler, and you
want to prevent them from changing the adjustments you have made.
To enable executive mode, press the horizontal shift and vertical shift control
buttons simultaneously for two seconds. The LCD displays the
message at the left for eight seconds, and then changes back to
X-MODE
ENABLED
the default screens.
When executive mode is enabled, the only front panel button that can be used is the
input selection button. If any other button is pressed, the LCD displays the same
message for eight seconds, then changes back to the default screens.
To disable executive mode, press the horizontal shift and vertical shift control
buttons simultaneously for two seconds. The LCD displays the
X-MODE
message at the left for eight seconds, then changes back to the
DISABLED
default screens.
Resetting the scaler
You can perform two types of reset:
• Channel reset restores the factory default picture control settings (color, tint,
brightness, contrast, horizontal shift, and vertical shift) for only the currently
selected input.
If input 4 (RGB pass-through) is selected, you cannot perform a channel reset.
• System reset restores all factory default settings, including all picture controls for
all inputs, the output rate, and all configuration options available from the
LCD menu.
Channel reset
To perform a channel reset, press and hold the input button for two seconds. The
picture control settings for the active input are reset to their
factory default settings. The LCD displays a message similar to
INPUT 1

Serial Communication
The scaler’s RS-232 connector can be connected to the serial port output of a host
device such as a computer or control system. This connection makes software
control of the scaler possible. Figure 10 shows a scaler RS-232 connection to a host
serial port connector.

The protocol is 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control.
The scaler accepts SIS™ (Simple Instruction Set™) commands through the RS-232
port. SIS commands consist of one or more characters per command field. They do
not require any special characters to begin or end the command character sequence.
Each scaler response to an SIS command ends 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.)
RS-232 Programmer’s Guide
DVS initiated messages
When a local event occurs, such as a front panel operation, the scaler responds by
sending a message to the host. The DVS-initiated messages are listed below
(underlined).
(C) Copyright 1999, Extron Electronics, DVS 150, Vx.xx
The copyright message is initiated by the scaler when it is first powered on. Vx.xx
is the firmware version number.
Reconfig
The Reconfig message is initiated by the scaler when a new input is selected or
when any image adjustment is made.
The scaler does not expect a response from the host, but, for example, the host
program might request a new status.
4-2
DVS 150 Serial Communication
DVS error response
When the scaler receives an SIS command and determines that it is valid, it
performs the command and sends a response back to the host device. If the scaler
is unable to perform the command because the command is invalid or contains
invalid parameters, the scaler returns an error response to the host. The error
response codes are:
E01 — Invalid input channel number (too large)
E09 — Invalid function number (too large)
E10 — Invalid command
E13 — Invalid value (out of range)
Using the command/response table
The command/response table is shown on the next page. Lower case characters
are acceptable in the command field only where indicated. Symbols are used
throughout the table to represent variables in the command/response fields.
Symbol definitions are shown at the beginning of the table, as is an ASCII-to-
hexadecimal (HEX) conversion table. Command and response examples are shown
throughout the table.
Screen adjustment commands are not available if input 4 is selected.
Remote Contact Closure Operation
The RS-232 connector provides a way to control the scaler from a remote contact
closure device. This is made possible by using pins that are not normally 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 through the RS-232 connector, momentarily short
the pin for the desired input number (#) to the signal ground (pin 5). To force one
of the inputs to be selected continuously, leave the short to signal ground in place.
This will override any front panel input selection.

Control Software for Windows
The Signal Enhancement Products Control Program (part # 29-017-01), which is used
by the scalers, is compatible with Windows 3.1, 3.11, 95/98, and NT. It provides
remote control of scaler settings. Use version 3.2 or later.
Installing the software
The program is contained on a single 3.5-inch diskette, and it can run from the
floppy drive. However, it is usually more convenient to load and run the program
from the hard drive.
To install the software from the floppy disk onto the hard drive, run SETUP.EXE
from the floppy disk, and follow the instructions that appear on the screen. The
program occupies approximately 1 MB (megabyte) of hard-drive space.
By default, the Windows installation creates a C:\S_ENHANC directory, and it
places two icons (Signal Enhancement Products Control Pgm and Signal
Enhancement Products Help) into a group or folder named “Extron Electronics”.

Troubleshooting
Operating Problems
Troubleshooting
This section gives recommendations on what to do if you have problems operating
the DVS 150, and it provides examples and descriptions for some image problems
you might encounter.
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 attacking the problem.
2.
3.
Be prepared to backtrack in case the action taken doesn’t solve the problem.
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.
5.
Try simplifying the system by eliminating components that may have
introduced the problem or made it more complicated.
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”.
