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, one output high performance RGB and video scalers offering 59 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. 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 scaler from a computer.

• The optional IR 902 remote control, replicating most of the front panel controls.

• Ethernet control via IP Link enables the DVS 304 to be controlled and proactively 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.

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.

DVS 304 • Introduction1-2

ce-info@camboard.de

Input 4 — A 15-pin HD connector accepts an RGB, component video,

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 and/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.

Four ways to control the scaler — The scaler’s front panel, a computer or other

RS-232 control device, the optional IR 902 remote control, and GlobalViewer can all be used to control the scaler.

Scaled outputs — The DVS 304 offers 59 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 pulldown detection for NTSC and 2:2 film detection for PAL video sources

— These 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 pulldown. “Jaggies” and other image artifacts can result if conventional deinterlacing 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 pulldown 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, and a

half rack wide. It is rack mountable, or it can be placed on a table or other furniture. Rubber feet and rack mounting hardware are included.

Auto Image

When an image appears on the screen, the auto image feature consults a table of default parameters to see how it should display.

When a new signal is detected and auto image is set to “On”, the DVS 304 applies the default (sizing and centering) parameters for that signal’s resolution and frequency.

When a new signal is detected and auto image set to “Off”, the DVS 304 first searches the user memory table to find any user-defined parameters for that signal resolution. If found, the user defined parameters are automatically applied; otherwise, the DVS 304 applies the auto image feature as described above.

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”.

The Blue mode is not effective for RGB pass-through.

Autoswitch mode

The Autoswitch mode causes the highest numbered input, which 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 ( 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.

RGB Delay

The RGB delay feature applies a brief delay before displaying a new picture to a screen. This delay allows the display device to adjust to the new sync timing. This feature provides “no-glitch” switching.

You can set the blanking period 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. On input 4, a user can create custom OSD text to display on the screen.

These labels are displayed in a white box with black text in the upper 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). You can set the display time from 0 to 5 seconds in 1 second steps. The default

The DVS 304 allows you to 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.

For quick sizing setup, use the 16* 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 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.

Using the swap feature

Use the swap feature to switch the parameters between a main window and PIP window on a display. This feature is available only through SIS commands or IR remote.

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.

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:

SIS Programmer’s Guide

Host-to-scaler 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 = 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 (underlined).

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.

E01 — Invalid input number E10 — Invalid command E11 — Invalid preset number E12 — Invalid port number E13 — Invalid parameter E14 — Not valid for this configuration E17 — Invalid command for signal type E22 — Busy E24 — Privilege violation E25 — Device not present E26 — Maximum number of connections exceeded E27 — Invalid Event number E28 — Bad Filename/File not found

References to errors (at command descriptions on the following pages)

= Commands that give E14 (Invalid Command for this configuration) if sent to

Extron product whose current configuration does not support the command.

= Commands that give E24 (Privilege violation) if not administrator level

= Commands that may give E27 (Invalid Event number)

= Commands that may give E28 (File not found)

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 Control 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_ENHANC2.exe icon (shown at right). The Signal

Enhancement control window opens.

Installing the software

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

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. These features are described in the sections of this chapter that correspond to the parts of the control program where the features are found.

1. To run the control program, double-click on the DVS 304 Control Pgm icon in

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.

If the local system administrators have not changed the value, the factoryspecified default, 192.168.254.254, is the correct value for this field.

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.

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).

6. Click in the Password field and type in the appropriate administrator or

user password.

7. Click the OK button. 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.

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 4-4) 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 fields

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.

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.

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.

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.

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.

Scaler Settings page

The Scaler Settings page (figure 4-4) simulates elements of the DVS 304 menu system, but also allows you to set video input signals (for inputs 2 and 4 only), define output resolutions, and remotely define advanced configurations.

Note that resolutions in the Resolution drop-down menu are linked to refresh rates as shown in the “Available Scaler Output Resolutions and Rates” table in chapter 2, Installation and Operation.

Figure 4-4 — Scaler Settings page

Passwords

The fields on the Passwords page are for entering and verifying administrator and user passwords. Passwords are case sensitive and are limited to 12 upper case and lower case alphanumeric characters. Each password must be entered

Characters in these fields are masked by asterisks (*****).

The following characters are invalid in passwords: {space} + ~ @ = ‘ [ ] { } < > ’ “ ; : | \ and ?.

If you do not want to password protect an access level, leave the Password field and the Re-Enter password field blank. After entering the desired password in both fields, click the Submit button.

As shown in figure 4-5 below, password-protected connections allow two levels of protection: administrator and user. Administrators have full access to all DVS 304 switching capabilities and editing functions.

Figure 4-5 — Passwords page

Please keep in mind that

• Connecting via an Ethernet connection, entering SIS commands (see chapter 3, Serial Communication) or using the Windows program to access the DVS 304 is password protected.

• Connecting via the RS-232 port, entering SIS commands or using the Windows-based control program to access the DVS 304 is not password protected.

An administrator password must be created before a user password can be created.

To clear an existing password so that no password is required, delete the asterisks in the Password field and place a blank space in the field. Click the Submit button.

Firmware upgrade page

The Firmware Upgrade page (figure 4-6) provides a way to replace the firmware that is coded on the scaler’s control board without taking the scaler out of service, opening the scaler enclosure, and replacing the firmware chip.

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.

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.

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 lifting the cover straight up (figure A-1).

Remove Screws (8) from Top and Sides of Cover

Changes to electronic components must be performed by authorized service personnel only.

To prevent electric shock, always unplug the DVS 304 scaler from the AC power source before opening the enclosure.

Pull cover toward rear to clear connectors, then lift straight up.

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.
