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 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.

— 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.

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.

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 rack-

mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (e.g. use of power strips).

either N/A, 1, 2, or 3 to select a preset. The default is <N/A>.

2. To clear the preset, press the Next button.

Recalling a preset

Recalling a saved preset requires that the desired input be currently selected and that the input button be pressed successively to activate each saved preset (up to three). Each saved preset will display the message “Input #X Memory Y”, where “X” refers to the input (1 to 4) and “Y” refers to the preset (1 to 3).

In the absence of any saved presets, the “Input #X Memory Y” message will not be displayed for those presets.

Clearing a preset by pressing the Next button will also cause a return to the

Memory Preset menu.

To exit the Clear memory preset function without clearing a preset, press Menu.

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 re-apply to that output rate.

Input preset

Input preset saves current values for parameters such as input type, color, tint, contrast, brightness, detail, aspect ratio, horizontal start, vertical start, horizontal active, vertical active, phase, total pixels, horizontal position, vertical position, horizontal size, vertical size, zoom, and OSD text.

IP conguration

The IP Conﬁguration menu displays the IP address of the unit, the Subnet mask, and Gateway IP address.

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.

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”.

Auto switch mode

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 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.

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dene(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.

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.

“New” signals /rates that have not been previously detected by the DVS 304 are initially set-up using default parameters, then auto image is automatically applied and values stored. The next time the same signal is detected, the values stored in the auto memory location are applied.

“New” signals /rates that have not been previously detected by the DVS 304 are set-up using default parameters. If manual input and/or picture settings are made to the input, an auto memory location is created and recalled each successive time the input is detected.

Each change in input sync triggers an automatic auto image. When auto memory is disabled, each different signal is treated as a new signal and default picture controls and automatic auto image is applied. Any manual changes made to the image and picture controls are lost each time a new rate is detected.

Each change in input sync causes default values to be applied to the rate. Any manual changes made to the image and picture controls are lost each time a new rate is applied.

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.

3. Activate the PIP mode via an SIS command or IR remote; specify the PIP

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:

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.

Setting up the DVS to work with a Matrix switcher

The Sync to Matrix tool is a powerful tool which can simplify the control system necessary when using an Extron Matrix switcher and a DVS 304.

The “Sync to Matrix” script can sense when a new tie is made on the matrix is routed to the DVS and automatically recalls the input preset associated with the input on the matrix switcher. The input preset recalls all the settings for the input including the signal format, input sampling settings, and picture controls.

Figure 2-23 — DVS 304 devices connected to a Matrix switcher

To conﬁgure the input presets required using the Sync to Matrix tool, do the following:

1. Install and connect the DVS as described in the Quick Start Guide, with the exception of step 3. In place of this step, connect the DVS 304’s input #4 to one of the matrix switchers outputs.

Multiple DVS 304’s can be connected to a single matrix switcher.

2. On the matrix switcher, tie input 1 to the output connected to input 4 on the DVS (see ﬁgure 2-24). Refer to the matrix switchers users manual for method.

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

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.

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.

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:

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.

1. While setting up the switcher and the DVS to work together, set rthe RGB

2. Create a tie on the matrix switcher from desired input X to the output number

3. Immediately (within 1 second) recall the input preset on the DVS 304

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:

SIS™ Programmer’s Guide

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.

In X! All ] Reconﬁg ] (where X! is the input number). The DVS 304 sends this response when an input is switched.

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.

X! = Speciﬁc port number (01-99) X@ = Command data section

N For Web encoding only:

Data is directed to the speciﬁed port and must be encoded if it is non-alphanumeric. Because data can include either command terminator, it must be encoded as follows when used within the data section:

Space (Hex 20) must be encoded as %20

(Hex 25 32 30)

Plus sign (Hex 2B) must be encoded as %2B

(Hex 25 32 42).

(listed to 2 decimal places)

X1@ = Name is a text string of up to 24 characters

drawn from the alphabet (A-Z), digits (0-9),

and the minus sign/hyphen (-). The ﬁrst

character must be an alpha character. The

last character must not be a minus. No

blank or space characters are permitted,

and no distinction is made between upper-

and lowercase.

X1# = Local date and time format

Set format (MM/DD/YY-HH:MM:SS);

e.g., 06/21/02-10:54:00

Read format (day of week, date month

year (HH:MM:SS), e.g., Thu, 20 Feb 2003

characters coming into a serial port before

terminating the connection (min = 0,

max = 32767, and default = 10 = 100 ms).

The response is returned with leading zeros. In RS-232 commands, X1& is

optional.

X1* = Hardware (MAC) address

(xx-xx-xx-xx-xxxx)

X1( = Subnet mask (xxx.xxx.xxx.xxx). Leading

zeros are optional in setting values in each

X2! = Parameter to set either the Length of the

message to receive or a Delimiter value.

L = byte count (min = 0, max = 32767, and

default = 0L [0 byte count).

D = decimal value for the ASCII

character (min = 0, max = 00255, and

default = 00000D).

Value is placed prior to parameter; for

example, 3 byte length = 3L, and the

ASCII 0A delimiter is 10D. This

parameter is case sensitive; you must use

uppercase D and L. The response is returned with leading zeros. (X2! is an

optional parameter.)

X2@ = Verbose/Response Mode

(Default = 0 for Telnet connections;

1 for RS-232 host control).

0 = clear/none

1 = verbose mode

2 = tagged responses for queries

3 = verbose mode and tagged responses

for queries

N If tagged responses is enabled, all read

commands will return the constant string + the data, like setting the value does

(e.g. command: Esc CN } response: Ipn• x12]).

X3# = Password (12 characters = maximum

length; no special characters are allowed.)

N A user password cannot be assigned if no

administrator password exists; the E14 error code is returned. If the administrator password is cleared, the user password is also removed.

1 – 10=extended security levels 1 thru 10

11 = user

12 = administrator

X5$ = ASCII digit(s) representing the numeric

value of the data element read from the

event buffer (leading zeros are suppressed). X6$ = Broadcast repetition rate in seconds

(0 – 255 max; default = 0 = clear)

The response is returned with leading zeros.

1 – 11 = entry without password goes to

the level speciﬁed (if an admin password

exists). The response as returned a 2-digits

with a leading zero.

X6( = The number of seconds before timeout

on the IP connection:

(min = 1; max = 65000; default =

30 = 300 seconds). If no data is received

during the timeout period, the Ethernet

connection will be closed. Each step =

10 seconds. Applicable only when

connected via Ethernet. When connected

via RS-232 only the global timeout

commands apply (current returns E13).

The response is returned with leading

zeros.

Control Software for Windows

The included Extron DVS 304 Control Program for Windows offers another way to control the DVS 304 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 98, Windows NT, Windows 2000, and Windows XP. Extron’s DVS 304 Control Program is included with the scaler, and updates can be downloaded from the Extron Web site (http://www.extron. com).

Downloading the software

To download the software from the Web and install it on your PC’s hard drive:

1. On the Extron Web site, select the Download tab.

2. On the Download Center screen, select Software from the side-bar menu on

the left.

3. Locate the Signal Enhancement Products ﬁle from the list and click on it.

4. Follow the onscreen instructions to download the program to your PC.

5. Double-click the S_ENHANC.exe icon (shown at right). The Signal

Enhancement control window opens.

Installing the software from a CD

To install the software on the hard drive:

1. Insert the CD-Rom into your CD drive. The disk starts automatically.

2. If the disk does not start automatically, run LAUNCH.EXE from the CD.

3. Follow the instructions that appear on the screen.

By default, the installation creates a C:\Program Files\Extron\S-ENHANC directory and places a shortcut icon in it.

The conﬁguration program require approximately 32 MB of hard disk space.

Using the control program

Many items found in the DVS 304 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 304 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.

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 If the local system administrators have not changed the value, the factory-

4. 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:

The following characters are invalid in ﬁle names: {space} ~ @ = ‘ [ ] { }

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).

speciﬁed default, 192.168.254.254, is the correct value for this ﬁeld.

Figure 4-1 — Network Password window

N 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, and provides an overall view of the status of the complete scaler. It provides immediate system information, power status and serial port settings for the DVS 304 unit.

Conguration

The Conﬁguration tab includes pages that show the current system settings, scaler settings, passwords and ﬁrmware upgrade data for the DVS 304 series.

System Settings page

The Systems Settings page (ﬁgure 4-3) consists of ﬁelds where you can view and edit IP administration and system settings. Date and time information can be easily updated.

Figure 4-3 — System Settings page

IP settings elds

The IP settings ﬁelds provide a location for viewing and editing settings unique to the Ethernet interface. After editing any of the settings on this page, click the Submit button. Explanations for some of these ﬁelds follows.

Unit Name

This name ﬁeld can be changed to any valid name, up to 12 alphanumeric characters.

N The following characters are invalid in the name: {space} ~ @ = ‘ [ ] { } <

> ’ “ ; : | \ 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 im-

mediately 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.

2. Edit the address as desired.

3. Press the Tab key on the keyboard or click in another ﬁeld to exit the IP

Address ﬁeld.

4. Click on the Submit button to make the address change take affect.

Gateway IP Address

The Gateway IP Address ﬁeld identiﬁes the address of the gateway to the mail server to be used if the DVS 304 and the mail server are not on the same subnet.

The gateway IP address has the same validity rules as the system IP address.

Subnet Mask ﬁeld

The Subnet Mask ﬁeld is used to determine whether the DVS 304 is on the same subnet as the controlling PC or the mail server when you are subnetting.

Date/Time Settings elds

The Date/Time Settings ﬁelds (ﬁgure 4-3) provide a location for viewing and setting the time functions. The adjustable variables are month, day, year, hours, minutes, AM/PM, and (time) zone.

Change the date and time settings as follows:

1. Click the desired variable’s drop box. A drop down scroll box appears.

2. Click the desired value.

3. Repeat steps 1 and 2 for all variables that need to be changed.

4. If appropriate, select the Daylight Savings radio button for the DVS’s region,

5. Select the Zone variable that is relevant for the DVS’s location.

5. Click Submit. The device is updated with the new settings.

For quick setting of the date and time, click the Local Date/Time.

Click Cancel at any point before submitting to exit any ﬁeld changes. The unit is not updated with those changes The screen refreshes and shows the current device settings.

to turn on the daylight savings time feature.

When a locations daylight savings time is turned on, the switcher automatically

updates its internal clock between Standard Time and Daylight Savings Time in the spring and fall on the date that the time change occurs in the country or region selected. When Daylight Savings Time is turned off, the switcher does not adjust its time reference.

The Zone ﬁeld identiﬁes the standard time zone selected and displays the

amount of time, in hours and minutes, that the local time varies from the GMT international time reference.

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).

B-6

Figure B-1 — Installation of the SDI card

DVS 304 • Reference Material

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.
