Introduction
About this Manual
About the DVS 304, DVS 304 D, DVS 304 A, DVS 304 AD
Introduction
About this Manual
This manual discusses how to install, configure, and operate the Extron DVS 304
video and RGB scaler and how to operate the optional IR 902 infrared remote
control (part #70-495-01).
Throughout this manual the terms “DVS”, “digital video scaler”, and “scaler” are
used interchangeably to refer to the same product. All instances refer to all models
in the series unless noted otherwise.
About the DVS 304, DVS 304 A, DVS 304 D, and
DVS 304 AD
The DVS 304 series (DVS 304, DVS 304 A, DVS 304 D, and DVS 304 AD ) are
4-input, 1-output high performance RGB and video scalers offering 62 output
rates, including HDTV. These products provide scaling solutions for boardrooms,
conference rooms, and home theaters, as well as rental and staging applications.
The two DVS 304 scalers come in a half rack model (DVS 304) with an SDI option,
and a full rack model (DVS 304 A) with an SDI option and balanced/unbalanced
audio.
All versions of the DVS 304 can be controlled remotely using Extron’s Simple
Instruction Set (SIS™) commands via RS-232, or through an Ethernet LAN
connection using embedded Web pages.
The DVS 304 scales from composite video, S-video, component (Y, R-Y, B-Y) video,
and RGB video to computer-video (RGBHV/RGBS/RGsB) or HD component.
It can also output to two separate display devices via individually buffered BNC
and 15-pin HD connectors.
Controlling the DVS 304 video and RGB scaler
The DVS 304 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. The Extron
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 902 remote control, replicating most of the front panel
controls.
• Ethernet control via IP Link, enabling the DVS 304 to be controlled and
pro-actively monitored over a LAN, WAN, or the Internet.
Features
Four inputs:
SDI video input (optional) — One BNC connector on the rear panel accepts
SDI video. During setup, the SDI input is assigned to input 1, 2, 3, or 4
(the default is none).
Input 1 — One BNC connector on the rear panel accepts composite video.
Input 2 — Three BNC connectors on the rear panel accept composite video,
S-video, or component video.
Input 3 — A 4-pin mini-DIN connector accepts an S-video signal.
Input 4 — A 15-pin HD connector accepts an RGB, component video,

DVS 304 • Introduction
S-video or composite video signal.
RGB and video scaling — Provides a high performance scaling engine with
the capacity to scale standard definition video, high definition video, and
computer-video signals up or down in resolution.
Picture Control — Allows size, position, brightness, contrast, color, tint, detail,
zoom and pan adjustments for each input.
Picture-In-Picture — Allows for a low resolution (YUVi, S-video, and composite
video) input or a high resolution (VGA and YUVp) input for the primary or
secondary picture.
Memory and input presets — Memory presets save sizing, positioning, and picture
control settings.
Input presets (on input 4 only) save input configuration, picture control, and
OSD (on-screen display) text.
Auto image™ — Auto image automatically sizes, centers, and optimizes the image
to that of the scaled output rate, filling the window with the image.
IP Link® — IP Link-enabled products offer an integrated Web server with high
performance architecture, global compatibility with industry standard
Ethernet communication protocols, multi-user support, and a Web-based
asset management application specifically designed to work with products
that include IP Link technology.
Buffered video outputs — Five rear-panel BNC connectors and one VGA-type
15-pin HD connector provide connections for RGB or Y, R-Y, B-Y output.
Both outputs (the BNCs and 15-pin HD connector) are active at all times for
simultaneous output.
Device control — The scaler has four methods of control; by the scaler’s front
panel, via a computer or other RS-232 control device, using the optional IR
902 remote control, or via Signal Enhancements Windows Control Program.
Scaled outputs — The DVS 304 offers 62 different output rates.
RS-232 configuration — The DVS 304 can be configured by using the Extron control
software for Windows or by using a third party control system.
Front panel security lockout (executive mode) — To prevent accidental changes
to the unit’s settings, the DVS 304 provides front panel lockout of all controls
except input switching.
3:2 pull down detection for NTSC and 2:2 film detection for PAL video sources
— These patented, 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 pull down. “Jaggies” and other
image artifacts can result if conventional de-interlacing techniques are used
on
film-source video. The DVS 304’s advanced film mode processing recognizes
signals that originated from film. The DVS 304 then applies video processing
algorithms that optimize the conversion of video that was made with the
3:2 pull down 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 304 and DVS 304 D are 1U high, half rack
wide rack mountable devices. Alternatively, they can be placed on a table or
other furniture. Rubber feet and rack mounting hardware are included.
The 1U high and full rack DVS 304 A and DVS 304 AD (audio models) can be
rack mounted using included rack/through-desk mounting brackets.

Mounting the Scaler
The DVS 304 is 1U high, half rack wide, and is rack mountable. Alternatively, it can
be placed on a table or other furniture. Rubber feet and rack mounting hardware
are included.
The 1U high and full rack DVS 304 A (audio model) can be rack mounted using
included rack/through-desk mounting brackets.
Tabletop/desktop placement
Four self-adhesive rubber feet are included with the DVS 304. For tabletop use,
attach one foot to each corner of the bottom side of the unit and place the unit in the
desired location.
UL guidelines for rack mounted devices
The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the
DVS in a rack.
2-2
1.
Elevated operating ambient temperature — If installed in a closed or multi-unit
rack assembly, the operating ambient temperature of the rack environment may
be greater than room ambient temperature. Therefore, install the DVS 304 in an
environment compatible with the maximum ambient temperature
(Tma = +122 °F, +50 °C) specified by Extron.
2.
Reduced air flow — Install the equipment in a rack so that the amount of air flow
required for safe operation of the equipment is not compromised.
3.
Mechanical loading — Mount the equipment in the rack so that a hazardous
condition is not achieved due to uneven mechanical loading.
4.
Circuit overloading — Connect the equipment to the supply circuit and consider
the effect that circuit overloading might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment nameplate ratings should
be used when addressing this concern.
5.
Reliable earthing (grounding) — Maintain reliable grounding of rackmounted equipment. Pay particular attention to supply connections other
than direct connections to the branch circuit (e.g. use of power strips).
DVS 304 • Installation and Operation
Rack mounting the DVS 304
1.
If feet were installed on the bottom of the DVS 304, remove them.
2.
Place the DVS 304 on one half of the 1U (one unit high, one unit wide) rack
shelf (part #60-190-01). Align the front of the DVS 304 with the front of the
shelf, and align the threaded holes on the bottom of the DVS 304 with the
holes in the rack shelf.
3.
Attach the DVS 304 to the rack shelf with the two provided 4-40 x 1/16"
machine screws. Insert the screws from the underside of the shelf, and
securely fasten them into diagonally-opposite corners (figure 2-1).

Auto imaging allows you to “auto size” and “auto center” the selected image to
fill the screen. The processor measures the sync frequencies of an incoming video
source and uses an internal table to set the active image area, total image area, and
the sampling frequency.
If an unknown input is connected to the DVS 304, the processor measures and
estimates the resolution of the incoming video.
To turn on this feature, select the Advanced Config menu and choose “On”.

Auto Image
When enabled and a new input frequency is detected, the DVS will first apply an
existing Auto Memory for the signal (if Auto Memory is enabled), or if no entry
exists, will perform an automatic Auto Image on the new signal.
With Auto Image disabled, the DVS 304 will apply default values to a new input if
no Auto Memory exists (if Auto Memory is enabled). Default is off.
Please see the table in the Auto Memory section for a full description of the
interaction between the Auto Image and Auto Memory settings.
N An input with a vertical refresh rate less than 40 Hz must be manually centered
and sized, using H/V Start and H/V Active under the Input Config menu.
When a rate with a low vertical refresh rate (e.g. 720p 29.9 Hz) is applied and an
Auto Image command is issued, the DVS 304 will refer to default values instead
of performing a true Auto Image.
Blue mode
The Blue mode assists the user in setting up a scaler’s color and tint level. To use
this feature, set 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 select this mode.
The default state is “Off”.
N The Blue mode is not effective for RGB pass-through.
Auto switch mode
The Auto switch mode causes the highest numbered input having 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”.
N The Auto switch mode ignores the presence of an SDI input signal, so any input
which is assigned an active SDI signal will not be selected.
2-18
DVS 304 • Installation and Operation
RGB Delay
The RGB delay feature applies a brief delay before displaying a new picture to a
screen and allows the display device to adjust to the new sync timing. This feature
provides “no-glitch” switching.
The blanking period can be set from 0 to 5 seconds in 0.5 second steps.
OSD label
Use the On-Screen Display (OSD) label menu to determine the time allotment for
an input label or a user defined OSD label. Input labels are generic labels shown
for inputs 1, 2 and 3. For input 4, the user can create a custom OSD label to display.
The OSD labels are displayed (white box, black text) in the top left-hand corner.
The OSD label can be turned off by setting its duration to “Off” from the Advanced
Configuration menu. For OSD text, note the following:
•Line 1 displays the input number. • Line 2 displays the input type.
•Line 3 displays a text label that you can define (input 4 only). The display time can be set from 0 to 5 seconds in 1 second steps (default is 2 secs).
Test pattern
Test patterns are useful when the DVS 304 is used to output differing resolutions.
Choose a test pattern to properly adjust the image using built in crop, alternating
pixels, and color bars.
Enhance mode
When the enhance mode is set to on, automatic gain control of the video input
signal is enabled. If the input signal level is too weak, signal gain will be increased,
and if the input signal level is excessive, signal gain will be decreased.
Using either the Adjust horizontal ([) or Adjust vertical ({) knob, select (< >)
either On or Off as desired. The default is Off.
Refresh Lock
When Refresh Lock is applied the vertical output rate is locked to the incoming
vertical refresh rate to prevent tearing and/or stutters associated with frame
conversion. This mode should only be activated when excessive stuttering and/or
tearing is being experienced with an input signal.
N The output refresh rate must be set equal to or greater than the incoming video’s
refresh rate or no video output will be displayed.
If the incoming video’s vertical rate differs significantly from the set output
refresh rate, no video will be displayed.
Auto Memory
The DVS 304 stores 16 auto memories with input and picture control data for inputs
2 ad 4. The default settings enables these memories to automatically recall input
and picture controls for signals that have been previously applied. By disabling
auto memories, the DVS 304 will treat every newly applied input as a new input.
Default is on.

Installation and Operation, cont’d
Picture-in-picture mode
The DVS 304 can display two image sources on the screen simultaneously. Keep
in mind that when using the PIP feature, one image source must be low-resolution
(composite, S-video, YUVi and RGBcvS) video, while the other must be high
resolution (YUVp, RGB scaled) video. If these conditions are not met (i.e., two low
resolution video inputs or two high resolution inputs are selected), the PIP mode
will quit.
To go into Picture-in-picture mode, do the following:
1.
Select an input for the main window.
2.
Define the size of the main window before starting PIP mode.
N For quick sizing setup, use the 16*# X10% SIS command to set different sizes for
the PIP window.
3.
Activate the PIP mode via an SIS command or IR remote; specify the PIP
window input.
DVS 304 checks the input format for the PIP window and returns an error message
if an invalid selection is made.
When the PIP mode is active, note the following:
•
The LED for the main window input is ON.
•
The parameters of the PIP window are adjustable from the front panel or by
SIS commands only.
•
Any change in configuration (except positioning) of the PIP window is saved
to that input even after the PIP mode is not longer active.
•
The PIP window input is listed under the default cycle on front panel menu,
as shown below.

If the PIP window source is out, the PIP mode exits until an active signal is
detected. When the main window source is removed, a black background
displayed.
Changing the input
To change the input for the PIP and/or main window, determine if the
corresponding input is a low or high resolution.
If your main window image is from a low resolution source, switch to another low
resolution input from the front panel. In this case, the PIP window retains its high
resolution.
When the PIP window is active, size, position, and picture controls all apply to the
PIP window. The main window settings cannot be modified while the PIP window
is active. The PIP size and position can be adjusted with the same front panel
controls or SIS commands used to adjust the main image.

DVS 304 • Installation and Operation
Using the swap feature
Use the swap feature to switch the active main window input with the current
PIP input. For example if the main window is Input 4 (RGB scaled) and the PIP
window is Input 1 (composite), applying the swap command results in Input 1
becoming the main window and Input 4 the PIP window.
For audio models (DVS 304 A or AD), you can allow audio to follow the main
(default) or PIP window. Audio breakaway is not possible while PIP mode is on;
audio must follow either the main window or the PIP window.

3.
On the DVS 304, configure the input as follows:
a). Switch to input 4 on the DVS.
b). Set the following input sampling settings as desired: signal type,
horizontal and vertical start, pixel phase, total pixels, active pixels, and
active lines
N Do not use auto detect setting for the input type when using input presets.
c). Set the following picture controls as desired: size, position, color, tint,
brightness, contrast, and detail.
d). Save the adjusted settings as input preset 1. Refer to chapter 3, “Serial
Communication”, for the SIS commands to save the preset.
N Each input preset must be saved with the same number as the input on the
matrix switcher. For Example, input 24 on the matrix will be associated with
the input preset 24 on the DVS.
e). Repeat steps 2 and 3 for each input on the matrix that is to be used on the
DVS 304.
4.
Synchronize the DVS to the matrix switcher as follows:
a). Open the Signal Enhancements Windows Control Program and connect
to the DVS 304.
N Connection must be via IP (not RS-232).
b). From the Tools menu, select Sync DVS304 to Matrix Switcher... . The
Sync DVS304 to Matrix Switcher window opens.
c). In the IP Address field, enter the matrix switcher’s IP address.
d). Click Connect to Matrix button. The matrix switcher’s size is displayed
below the button.
e). From the drop-down menu next to Matrix Output feeding DVS 304
Input 4: select the matrix output number that is connected to Input 4 on
the DVS 304.

DVS 304 • Installation and Operation
f). Click Take button to tie the DVS 304’s input to the selected switcher
output. The program will create a custom script that will then be loaded
onto the DVS 304. The Status box updates with the status of the script on
the DVS 304, showing if the DVS 304’s script is connected to the matrix
switcher, and showing the current tie associated with output selected.
Using the DVS and matrix switcher after the DVS is
synchronized to the matrix switcher.
After completing step 4, above, ensure the following is done when using the DVS
with the matrix:
•
Perform all input switching using the matrix switcher. A 1-second RGB
delay on the matrix is recommended to minimize the appearance of a
glitch in the output while the DVS locks onto the new signal.
•
The DVS senses when the matrix switcher changes input ties and
recalls the matching input preset, so Input presets need not be recalled
manually.
•
The DVS 304 and the matrix switcher must remain on the same subnet.
Do not change the matrix switcher’s IP address. If the IP address of the
matrix is altered, repeat step 4 above.

Removing the Sync to Matrix Script
If the Sync to Matrix feature is no longer being used, the script can be removed
from the DVS by the following steps:
1.
Open the Signal Enhancements Windows Control program and connect to the
DVS via IP (not RS-232).
2.
Under the Tools menu, select Sync DVS 304 to Matrix Switcher... . The Sync
DVS 304 to Matrix Switcher window opens.
3.
Click Remove Script.
Minimize synchronization problems without using the Sync to Matrix
feature
This section describes how to manually implement the equivalent of the Sync to
Matrix feature without using a script loaded on the DVS 304, and instead relying
on a control system.
When operating the system using a manually configured control system (for which
Sync to matrix has not been setup), you can avoid synchronization problems that
cause unwanted image blanking or scrambling during input switches by doing the
following.
N If the Sync to Matrix feature has been previously used, first see Removing the
Sync to Matrix Script section above.
1.
While setting up the switcher and the DVS to work together, set rthe RGB
delay on the matrix switcher, equal to, or greater than 1.0 second.
2.
Create a tie on the matrix switcher from desired input X to the output number
that corresponds to the DVS 304’s Input 4.
3.
Immediately (within 1 second) recall the input preset on the DVS 304
associated with the input X on the matrix switcher.
N Input presets cannot be recalled via the DVS 304’s front panel. You can recall
them via SIS commands (see chapter 3, “Serial Communication”).

Serial Communication
The DVS 304 can be remotely controlled via a host computer or other device (such
as a control system) attached to the rear panel RS-232 connector or the LAN port.
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:

Host to-scaler and scaler to host 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 304 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.
Scaler-initiated messages
When a local event such as a front panel selection or adjustment takes place, the
DVS 304 scaler responds by sending a message to the host. No response is required
from the host. The scaler-initiated messages are listed here.

Using the command/response tables
The following are either Telnet (port 23) or Web browser (port 80) commands. There are some
minor differences when you are implementing these commands via Telnet or via URL encoding
using a Web browser. All commands listed below will work using either connection method but,
due to some limitations of the Web browser, the encapsulation characters are modified to make
sure that the Web browser will properly handle them. All examples in the command/response
table show the proper implementation in a Telnet or Web browser session.
N
3-2
Note for Web browsers: all non-alphanumeric characters must be represented
as their hex equivalent, such as %xx where xx equals the two character
representation of the hex byte that needs to be sent (e.g., a comma would be
represented as %2C).

When SIS commands are used through a Web browser, the URL reference is used
below to shorten the examples. This would in practice be the full URL of the
control interface and Web page reference including all path information.
(e.g., http://192.168.254.254/index.html)
To send any of the commands using a Web browser you need to prefix them with
the full URL followed by ?cmd=. See URL Encoding later in this chapter.
N
With Telnet you can use either the Escape commands or the W commands, and
the carriage return or the pipe ( ) character. With the Web browser you are
required to use the W commands and the pipe character.
In either method {Data} = Data is directed to a specified port and must be encoded
if non-alphanumeric.
The Command/response table for Simple Instruction Set (SIS) commands later in this
chapter lists the commands that the DVS 304 scaler recognizes as valid, the
responses that are returned to the host, a description of the command’s function or
the results of executing the command, and an example of each command in ASCII
(Telnet) and URL Encoded (Web).

Ethernet Control
Accessing and Using the Web Server
Navigating the Default Web Pages
Ethernet Control
The DVS 304 features an on-board Web server, displayed as a set of default Web
pages. These pages allow you to control and operate the DVS 304 unit through
its Ethernet port, connected via a LAN or WAN, using a Web browser such as
Microsoft’s Internet Explorer (version 5.5 or higher), or Netscape Navigator
(version 6.0 or higher).
This chapter describes these default Web pages, which are always available and
cannot be erased or overwritten.
Accessing and Using the Web Server
Access the DVS 304 through the on-board Web server pages as follows:
1.
Double click the Web browser icon on your Windows desktop to launch your
Web browser.
2.
Click in the browser’s Address field.
3.
Enter the unit’s IP address in the browser’s Address field.
N
4.
If the local system administrators have not changed the value, the factoryspecified default, 192.168.254.254, is the correct value for this field.
If you want the browser to display a page other than the default page (such as
a custom page that you have created and uploaded), enter a slash (/) and the
file name to open.
N
The browser’s Address field should display the address in the following format:
xxx.xxx.xxx.xxx/{optional_file_name.html}
The following characters are invalid in file names: {space} ~ @ = ‘ [ ] { }
< > ’ “ ; : | \ and ?.
5.
Press the keyboard Enter key.
The DVS 304 checks to see if it is password protected.
If it is not password protected, proceed to step 7.
If it is password protected, the DVS 304 downloads the Enter Network
Password page (figure 4-1).
Figure 4-1 — Network Password window
N
4-2
A User name entry is not required.
6.
Click in the Password field and type in the appropriate administrator or user
password.
7.
Click the OK button.
DVS 304 • Ethernet Control
The scaler checks several possibilities, in the following order, and then responds
accordingly:
a.
Does the address include a specific file name, such as
10.13.156.10/file_name.html? If so, the DVS 304 downloads that HTML
page.
b. Is there a file in the scaler’s memory that is named “index.html”?
If so, the scaler downloads “index.html” as the default start-up page.
c.
If neither of the above conditions is true, the scaler downloads the
factory-installed default start-up page, “nortxe_index.html”
(figure 4-2, shown below), also known as the System Status page.
Navigating the Default Web Pages
The DVS 304 default Web pages include four tabs (Status, Configuration, File
Management, and Control) for easy navigation of several administrative options
including system status, password control, file management, and scaler settings.
Status
The Status tab displays the System Status page for the DVS 304.
System Status page
The System Status page (figure 4-2), is the default page of the on-board Web server,
provides an overall view of the status of the complete scaler. It provides
and
immediate system information, power status and serial port settings for the DVS
304 unit.

> ’ “ ; : | \ and ?.
DHCP
The Dynamic Host Configuration Protocol (DHCP) is an Internet protocol for
automating the configuration of computers that use TCP/IP. DHCP can be used to
automatically assign IP addresses, deliver TCP/IP stack configuration parameters
such as the subnet mask and default router, and provide other configuration
information such as the addresses for printer, time and news servers. For specific
settings information, see your system administrator.
IP Address
The DVS 304 IP Address field contains the IP address of the connected scaler. This
value is encoded in the flash memory in the scaler.
Valid IP addresses consist of four 1-, 2-, or 3-digit numeric subfields separated by
dots (periods). Each field can be numbered from 000 through 255. Leading zeroes,
up to 3 digits total per field, are optional. Values of 256 and above are invalid.
4-4
DVS 304 • Ethernet Control
The default address is 192.168.254.254, but if this conflicts with other equipment at
your installation, you can change the IP address to any valid value.
N
Editing the Extron IP address while connected via the Ethernet port can immediately disconnect the user from the scaler. Extron recommends editing this
field using the RS-232 link and protecting the Ethernet access to this screen by
assigning an administrator’s password to qualified and knowledgeable personnel only.
Edit this field as follows:
1.
Click in the DVS 304 IP address field. The graphic cursor becomes a text
cursor.

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.
N
Changes to electronic components must be performed by authorized service
personnel only.
Follow these steps to install an SDI card in the DVS 304.
1.
Disconnect the AC power cord from the DVS 304 to remove power from the
unit.
W To prevent electric shock, always unplug the DVS 304 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 slide the cover back to clear the connectors and lift it straight up
(figure B-1).
Remove Screws (8)
from Top and Sides of Cover
Pull cover toward rear

W 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)
5.
Remove the plastic SDI cover from the rear SDI connector opening of the
scaler and position the SDI card at an angle with the SDI connector protruding
from the rear SDI connector opening.
6.
The SDI card has a 20-pin socket on the underside which should align with
the 20 pins on the main circuit board. Be sure to align the pins properly, in
order to prevent bending the pins, before pressing the SDI card firmly in
place against the standoff. The mounting hole on the SDI card should now be
directly over the standoff.
7.
Insert the card’s installation screw through the SDI card’s mounting hole and
gently tighten it into the standoff.
8.
Install the SDI connector’s hex nut and keep the SDI card from twisting as the
nut is tightened.
9.
Replace the top cover on the DVS 304 scaler, and fasten it with the screws that
were removed in step 3.
10. Rack/furniture mount the scaler, if desired, and reconnect the AC power cord.
