Introduction  
About the Scaler  
Extrons 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:  
640 x 480 (VGA) at 60 or 75 Hz (Hertz)  
800 x 600 (SVGA) at 60 or 75 Hz  
832 x 624 (Macintosh) at 60 or 75 Hz  
848 x 480 (plasma) at 60 Hz

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.

Operation, contd  
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 scalers 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 Programmers 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 doesnt 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 Extrons 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 users 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.
