Introduction

This manual contains installation, configuration, and operation information for Extron’s VSC 200, VSC 200D, VSC 300, and VSC 300D scan converters.

The VSC 200 and VSC 300 down-convert computer video to NTSC or PAL format, which can be recorded, used for videoconferencing, or viewed on an NTSC or PAL monitor or other display device. The VSC 300 also outputs VGA/SVGA for display on a PC or Mac monitor.

An optional digital module adds a digital video output. The VSC 200D and the VSC 300D models include the module, and the VSC 200 and VSC 300 models can be upgraded to include the module. The upgrade can be performed as a field upgrade, or the scan converter can be returned to Extron for upgrade.

Features

Autoscanning — Automatically recognizes and converts the incoming computer

image. The VSC 200/VSC 200D supports up to 1280 x 1024 resolution, 70 kHz horizontal and 120 Hz vertical scan rates. The VSC 300/300D supports up to 1600 x 1280 resolution, 100 kHz horizontal and 120 Hz vertical scan rates.

NTSC and PAL output — The scan converters are compatible with any display or

recording device that uses the NTSC or PAL standard.

VGA/Mac input — Accepts 15-pin D and HD connectors, allowing easy connection

to most computers. The passive local monitor output allows you to display the same image on the local monitor as is displayed or recorded on an external device.

13W3 compatible — Using the VGA/13W3 cable and Mac/13W3 cable that are

provided with the VSC 300/300D, a 13W3 computer and local monitor can be attached.

High quality zoom control — Uses increased pixel clocking for variable zoom,

providing better quality of the displayed image.

Horizontal and vertical controls — Provides controls for sizing and centering the

image. This provides increased flexibility for panning across the image while zooming.

Horizontal and vertical filtering — The VSC 200/200D provides four levels of

horizontal and five levels of vertical filter control. The VSC 300/300D provides eight levels of horizontal and ten levels of vertical filter control. These user-selectable filtering controls reduce flicker and ensure that no picture detail is dropped during scan conversion.

High quality color sampling — Uses 24-bit sampling and provide 8 bits per color,

for a total of 16.8 million colors.

Memory presets — Uses approximately 130 memory locations to store presets that

include size, zoom, pan, centering, and filter control settings for various scan rates. The user can specify 30 of these presets, and the remainder were set at the factory. The scan converter automatically loads the control settings from the preset associated with the scan rate of the input video signal.

RS-232 control — Provides control for third-party remote control of features and

functions that can be programmed by using Extron’s Simple Instruction Set™

(SIS

Outputs — Outputs NTSC and PAL video as composite, Y/C (S-video), component

(R-Y, B-Y, Y), and RGBHV. The VSC 300 and VSC 300D also output scalable SVGA/VGA.

) or Extron’s control software for Windows.

VSC 200/200D/300/300D Introduction1-2

Genlock — Allows the integration of the scan converted images into a professional

broadcast environment. Genlocking provides for seamless vertical interval switching of converted high resolution sources with other video sources.

Digital video output (optional) — Available as standard on the VSC 200D and

VSC 300D, or can be added to the VSC 200 and VSC 300 via the VSC 200/300 D1 Module.

Installation Overview

To install the scan converter, follow these general steps:

If desired, mount the scan converter in a rack (see “Mounting the scan

converter” on page 2-5). Otherwise, install the rubber feet (see “Tabletop/ desktop placement” on page 2-6).

Turn off power to the input and output devices, and unplug the power cables

from them.

Attach the input device and the output device to the scan converter. See

“Cabling” on page 2-6.

Set the configuration switches.

Plug the scan converter, input device, and output device into a grounded AC

source.

Turn on the input and output devices.

Use the LCD menu screens to configure the scan converter. See “Front Panel

Operation”, page 3-2.

The image from the input device should appear on the output device. If it

does not, double check steps 3 and 4 and make adjustments as needed. See chapter 5 for additional assistance.

Optimize the image for your display environment. See “Optimizing the

image” on page 3-5.

VSC 200/200D/300/300D Installation2-4

Mounting the scan converter

The scan converter ships with four uninstalled rubber feet. If you are going to rack mount the unit, do so before cabling the unit, and do not install the rubber feet. If you are not rack mounting the scan converter, skip to “Tabletop/desktop placement” on page 2-6.

Rack mounting

To rack mount the scan converter, do the following:

1. Attach the mounting brackets (supplied with the scan converter) on either side of the scan converter, as shown in figure 5. Use four screws per mounting bracket.

The scan converter preset memory contains 130 locations that store scan rates and associated size, zoom, pan, centering, and filter controls. The 30 user presets can be changed or erased. The remaining locations are factory-loaded, permanent presets that cannot be changed or erased.

When a video input is connected, the scan converter automatically scans the user presets and then the factory presets, looking for a match to the input scan rate. If a match is found, the stored settings become the active settings. If no match is found, a user preset is created automatically using the default settings. If the user preset memory is full, the new user preset overwrites the oldest user preset.

If a user preset is active and changes are made to the zoom, size, pan, or filter controls, the changed settings are stored automatically in the preset memory for the active scan rate. If a factory preset is used and changes are made to the zoom, size, pan, or filter controls, a new user preset that includes the new settings is created.

To reset all user presets, perform a system reset (see page 3-4).

Preset memory does not include selections from the configuration controls menu. The scan converter uses only the most recently applied configuration controls selections.

Setting Up Genlock and Vertical Interval Switching

A genlock (black burst generator) device can be connected to the scan converter to synchronize it with other system components for seamless vertical interval switching between sources.

Vertical interval switching setup

For vertical interval switching (to allow clean switching between signals from several devices during the vertical blanking period of each signal), a composite sync signal can be applied at the Genlock In connector, and also passed to another device via the Genlock Out connector.

VSC 200/200D/300/300D Operation3-6

If the genlock connectors are used only for vertical interval switching, no horizontal or subcarrier phase adjustments are required, and the genlock LED does not light.

Genlock setup

Genlock differs from simple vertical interval switching in that an external device (a black burst generator) generates a reference sync signal for the system, and every device that uses that signal has its output signal’s horizontal and subcarrier phases adjusted to exactly match that of the generator to allow precise timing and full synchronization. Genlocked systems produce cleaner switches between inputs than do those without this type of synchronization.

An oscilloscope is required for genlock setup, and a vectorscope is recommended. Waveform monitors of types other than a vectorscope may give the appearance that timing is adjusted correctly when it is 180 degrees out of phase, which will result in incorrect colors or picture artifacts.

To synchronize the scan converter’s video output with a genlock signal, follow these steps:

1. Power up and turn on all the devices that will use the genlock signal. The devices must be on for at least 15 to 20 minutes before proceeding with any adjustments.

2. Connect the active timing source signal to the Genlock In connector on the rear panel (figure 21).

50/60 Hz 0.5A

100-240

All equipment in the system must be powered up and turned on for at least 15 to 20 minutes before genlock setup adjustments can be made and before the equipment is used in a genlocked application.

3. Connect the active computer video input signal to the appropriate input as explained in step 2 of the cabling section on page 2-6. Ensure that the input is properly terminated either by connecting a local monitor to the other input/ loopout (loop through) connector, or by setting the 75 ohm/Hi Z switch to 75Ω. The Genlock LED lights to indicate that the scan converter is receiving an acceptable genlock (black burst) sync signal via the Genlock In connector.

4. Connect oscilloscope (“scope”) probe A to the Genlock Out connector. This will provide the scope’s reference signal. In order to avoid altering the genlock signal, use the cabling configuration that will be used in the installation. Either connect the genlock signal cable from the scope to the next device in the system to be timed, or provide 75 ohm termination at the scope’s genlock output.

5. Connect scope probe B to the scan converter’s composite video output connector. Ensure that the standard screen of the configuration controls menu is set to the desired standard (NTSC or PAL; see page 3-3).

3-7VSC 200/200D/300/300D Operation

Operation, cont’d

6. Using the instructions for the scope you are using, set the scope to view the signals’ horizontal phases. From the phase adjust screen of the configuration controls menu, adjust the scan converter’s horizontal phase control until there is no (0º) difference between the composite video output’s horizontal sync phase and the genlock signal’s horizontal phase. See “Oscilloscope displays” on page 3-8, and “Configuration controls menu” on page 3-3.

7. Set the scope to view the subcarrier signals. From the phase adjust screen of the configuration controls menu, adjust the scan converter’s subcarrier phase until there is a zero phase difference between the genlock signal and the NTSC/PAL output. The Genlock LED should light.

8. View the horizontal phases again. If the phase difference is not zero, repeat steps 6 and 7 until the settings do not change.

9. After the settings are stable and the Genlock LED lights, disconnect the oscilloscope, and reconnect the genlock cables and terminator to the proper devices in the system.

10. Check the display for proper colors and for undesirable artifacts in the image. Make adjustments as necessary. After the genlock timing has been adjusted, it should not require readjustment when changing to a new computer video signal input.

11. If other scan converters are part of this genlock daisy chain, connect the oscilloscope to each device, and repeat this procedure.

If the Genlock LED does not light at this point, either adjust the horizontal or subcarrier phases further, or use a different genlock source.

The subcarrier adjustment range is +/- 180 degrees from 0 for a total adjustment range of 360 degrees.

If the Genlock LED does not light at all when genlock is active and the horizontal and subcarrier phases have been adjusted to match the genlock signal, do not continue with this procedure. A different, more stable or timebase-corrected sync signal must be used for the genlock timing source.

Oscilloscope displays

What you see on the oscilloscope while adjusting the scan converter to match the genlock signal depends on the type of signal used, the type of oscilloscope, and the procedure the scope requires. This section shows some examples of oscilloscope displays.

Figure 22 shows the genlock input signal (top) and an out-of-alignment NTSC composite sync output signal (bottom) displayed on a waveform monitor to check for alignment. When the phases are aligned, the wave peaks on the bottom waveform should line up with those in the reference signal above it.

VSC 200/200D/300/300D Operation3-8

With this method there is no way to know if the signals are 180º out of phase. A delayed sweep on a time-based scope would allow a more accurate display of the input and output signal phase relationships.

Serial Communication

The scan converter’s RS-232 connector can be connected to the serial port output of a host device such as a computer or control system. This connection makes software control of the scan converter possible. Figure 25 shows a scan converter RS-232 connection to a host serial port connector.

Figure 25 — Scan converter RS-232 to host connection

The RS-232 connector on the scan converter is a 9-pin D female connector with the following pin assignments:

Pin Description

1 Not used 2 Transmit data

3 Receive data 4 Not used

5 Signal ground 6 Not used

7 Not used 8 Not used

9 Not used

The protocol is 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control.

RS-232 Programmer’s Guide

The scan converter 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 scan converter response to an SIS command ends with a carriage return and a line feed (CR/LF = character string. A string is one or more characters.

VSC 200/200D/300/300D Serial Communication4-2

), which signals the end of the response

VSC-initiated messages

When a local event such as a front panel operation occurs, the scan converter responds by sending a message to the host. The VSC-initiated messages are listed below (underlined).

on. Vx.xx is the firmware version number.

Reconfig

The Reconfig message is initiated by the scan converter when the resolution of the input signal is changed and when the front panel LCD menus are exited, indicating that there may have been a change to the adjustments or parameters.

The scan converter does not expect a response from the host, but, for example, the host program might request a new status.

VSC error responses

When the scan converter receives an SIS command and determines that it is valid, it performs the command and sends a response to the host device. If the scan converter is unable to perform the command because the command is invalid or contains invalid parameters, the scan converter returns an error response to the host. The error response codes are:

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-tohexadecimal conversion table. Command and response examples are shown throughout the table.

Control Software for Windows

The VSC and DDS Control Program (Extron part number 29-038-01), which is used by the VSC 200/200D/300/300D, is compatible with Windows® 3.1, 3.11, 95/98, and NT. It provides remote control of input selection.

Installing the Software

The program is contained on a single 3.5” 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:\VSC200 directory, and it will place two icons (VSC + DDS Control Pgm and VSC + DDS Help) into a group or folder named “Extron Electronics”.

Using the Software

1. To run the VSC and DDS Control Program, double-click on the VSC + DDS Control Pgm icon (left) in the Extron Electronics group or folder.

2. Click on the comm port that is connected to the RS-232 port of

the VSC 200/200D/300/300D. The Extron VSC and DDS Control Program window appears (see figure 26).

It displays the current settings and the detected input scan rate.

Troubleshooting

The image should be displayed properly on the screen.

If the image does not appear

1. Ensure that all devices are plugged in.

2. Make sure that each device is receiving power. If the scan converter does not power on, and the AC power source is functioning correctly, the AC fuse may be blown. See “Replacing the AC fuse” on page B-4.

3. Check the cabling, wiring, and grounding, and make adjustments as needed. Ensure that the sync selection switch and output and standard screens of the configuration controls menu are set for the formats that match the cable configuration and the requirements of the display/recording devices.

4. Verify that the 75 ohm/Hi-Z switch has been set correctly.

5. To test the system setup and output, substitute a video test generator for the computer input.

6. Confirm that the input is receiving a signal with a compatible scan rate (horizontal frequency between 24 kHz and 80 kHz, and a vertical frequency of 50 Hz to 120 Hz, for the VSC 200/200D; horizontal frequency between 24 kHz and 100 kHz, and a vertical frequency of 50 Hz to 120 Hz, for the VSC 300/300D).

7. Call Extron’s customer support hotline if needed. Be prepared to discuss the steps you have taken and the equipment involved.

3. Remove the nut from the circuit card BNC connector and set it aside. Insert the D-1 circuit card BNC connector through the hole that was created in the rear panel in step 2.

4. Carefully align the D1 circuit card 20-pin female connector with the J16 pins on the VSC 200/300 motherboard (see exploded view 2 in figure 28). With the pins aligned, press down gently on the D-1 circuit card. Very little pressure is required to plug the connector onto the J16 pins. Check the alignment of the D-1 circuit card connector and VSC J16 pins if necessary.

Do not force the connection, or you might damage the D-1 circuit card or the VSC 200/300 motherboard.

5. Lay a straight edge across the top of the front and rear panels. If the circuit card is seated properly, the rubber spacer on the D-1 circuit card is flush with the top of the case.

6. Install and tighten the BNC nut that was set aside in step 3 (see exploded view 3 in figure 28).

7. Reinstall the cover of the scan converter.

8. If rack mount brackets were removed earlier, reinstall them.

9. Attach the power cord to the scan converter and to the AC power source. Make sure the scan converter is working correctly.
