Introduction

About this Manual

This manual contains information about Extron’s VSC 150 scan converter and how to install, operate and configure it. It also explains how to operate the IR 601 remote control.

About the VSC 150

Extron’s VSC 150 is a high resolution computer-to-video scan converter with all digital controls. The VSC 150 converts a computer video signal into two display outputs – composite video and one of the following:

• S-video,

• component video, or

• RGB video (RGBHV or RGBS) for simultaneous scan-converted output on two separate

devices. This allows the video from a computer to be displayed on a television monitor or recorded on a DVD, VCR, video editing bay or other recording device. All of the outputs are NTSC/PAL.

This scan converter accepts one Macintosh or VGA computer input of a resolution up to 1152 x 900 and provides a local monitor loop-out.

The VSC 150 is 1U high and one half rack wide. It is rack mountable, and has an internal, autoswitching power supply. It can be controlled via front panel buttons, RS-232 remote control, and infrared (IR) control.

The output cables must also be connected to the appropriate connector(s) for the second output.

Connect cables for only one output in addition to the composite video output. Do not connect cables to outputs that will not be used for your application. Connecting cables to more outputs will overload the circuits and yield weak signals.

RGB/component video output connectors — These

BNC female connectors are for RGB output (red, green, and blue video output; and horizontal, vertical, and composite sync output), or for component video output (R-Y, Y, B-Y). See “Cabling” in this chapter for details.

Optimizing the Image

After you have installed the scan converter, follow the procedures in this section in sequence. This will help you configure the scan converter for the best settings for your display environment.

Select the output standard

1. Select the output standard with the PAL Out DIP switch. This switch affects both display outputs (com-

posite video and one other), but not the local monitor.

ON — The output is in PAL format. OFF — The output is in NTSC format.

Size the image to fill the screen

1. Press the Size button on the front panel.

2. Rotate the vertical and horizontal Centering/Pan/Size

rotary controls to adjust the vertical and horizontal size. Observe the picture on screen as you adjust the controls. The Min/Max LED will light red when the minimum or maximum limit of a control is reached.

The size feature affects both display outputs, but local monitor loop-out is not affected. The size function remains active for 8 seconds after the rotary controls become inactive. The rotary controls then default to the standard centering and pan functions.

3. Press the Size button again to turn the size feature off.

4. Center the picture by rotating the vertical and

horizontal Centering/Pan/Size rotary controls.

5. Repeat steps 1 through 4 as needed.

Select the filtering levels

1. Press the horizontal, vertical and encoder filtering controls to select the filtering levels that give the best picture sharpness and the least amount of flickering. The LEDs next to each control will light to indicate the selected level of filtering.

If the filters are set before the image size is adjusted, you must set the filters again after adjusting the image size.

Setting Up Genlock and Vertical Interval Switching

A genlock (black burst generator) device can be connected to the VSC 150 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.

2-12

VSC 150 • Installation and Operation

2-13

Installation and Operation, cont’d

If the genlock connectors are used only for vertical interval switching, no horizontal or subcarrier phase adjustments are required, and the Burst Lock 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 VSC 150’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.

termination adapter to the other “input” connector, or by setting the 75 Ohm DIP switch to On (75 ohms). The Burst Lock LED lights green to indicate that the VSC 150 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 VSC 150’s composite video output connector. Ensure that the rear panel PAL Out DIP switch is set for the desired standard (NTSC/PAL).

6. Using the instructions for the scope you are using, set the scope to view the signals’ horizontal phases. Adjust the VSC 150’s Horz 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 “Oscillocope displays”.

7. Set the scope to view the subcarrier signals. Adjust the VSC 150’s Sub Phase control until there is a zero phase difference between the genlock signal and the NTSC/PAL output. The Burst Lock LED should light.

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

The color subcarrier adjustment range is ±90° from 0° for a total adjustment range of 180°.

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

If the Burst Lock 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 time-base-corrected sync signal must be used for the genlock timing source.

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

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

11. If other VSC 150s are part of this genlock daisy chain, connect the oscilloscope to each device, and repeat this procedure.

Oscilloscope displays

What you see on the oscilloscope while adjusting the VSC 150 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.

The figure below 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.

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.

Remote Control

The VSC 150 can be remotely controlled via a computer or a control panel attached to the rear panel RS-232 connector. Alternatively, the VSC 150 can be controlled using the IR 601 infrared remote control. This chapter discusses how to use each of these options to control the scan converter.

RS-232 Remote Control

The VSC 150 can be controlled by a host computer or other control device via an RS-232 connection with a protocol of 9600 baud, 1 stop bit, no parity, and no flow control. The

Host-to-VSC 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 VSC 150 determines that a command is valid, it executes the command and sends a response to the host device. All responses from the scan converter 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.

control device (host) can use either Extron’s Simple Instruction Set (SIS) or the graphical control program for Windows.

The VSC 150 displays the copyright message when it first powers on. Vx.xx is the firmware version number.

RECONFIG The VSC 150 sends the Reconfig message when the input source is changed and when changes have been made to one or more of the settings.

VSC error responses

When the VSC 150 receives a valid SIS command, it executes the command and sends a response to the host device. If the VSC 150 is unable to execute the command because the command is invalid or it contains invalid parameters, it returns an error response to the host. The error response codes and their descriptions are as follows:

E10 – Invalid command E11 – Invalid preset number E13 – Invalid value (the number is out of range).

Time-out

A delay of 10 or more seconds between command sequence characters causes a time-out. The command operation is stopped, and there is no indication that a time-out occurred.

Using the command/response table

The command/response table on the next page lists valid command ASCII codes, the VSC 150’s responses to the host, a description of the command’s function or the results of executing the command, and an example of each command. Lower case characters are acceptable in the command field only where indicated.

The ASCII to HEX conversion table below is for use with the command/response table.

VSC-initiated messages

When a local event such as a front panel selection or adjustment takes place, the VSC 150 responds by sending a message to the host. No response is required from the host. The VSC-initiated messages are listed here (underlined).

Control software for Windows

The included graphical control software for Windows offers another way to control the VSC 150 via RS-232 connection in addition to the Simple Instruction Set commands listed on pages 3-4 to 3-5. The control software is compatible with Windows 3.1/3.11, Windows 95/98 and Windows NT. The VSC 150 uses version 3.1 or higher of Extron’s VSC and DDS Control Program, which is included with the VSC 150.

Installing the software

The control program is contained on a single 3.5-inch diskette, and it can run from the floppy drive. However, it is more convenient to run the program from the hard drive.

To install the software on the hard drive, run SETUP.EXE from the floppy disk, and follow the instructions that appear on the screen. The program requires approximately 1 MB (megabyte) of hard disk space.

By default the installation creates a C:\VSC200 directory, and it places 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-

2. Click on the comm port that is connected to the VSC 150’s RS-232 port. The Extron VSC and DDS Control Program window appears. It displays the current settings. See the illustration on the next page.

For information on program features, press the F1

computer key or click on the Help menu from within the control program, or double-click on the VSC + DDS Help icon in the Extron Electronics group or folder.

click on the VSC + DDS Control Pgm icon in the Extron Electronics group or folder. The Comm menu appears on the screen.

IR Remote Control

The IR 601 infrared remote control can perform all the functions that are available via the front panel controls except the genlock adjustments.

The IR 601 remote

The IR 601 remote control can freeze the image, set filtering adjustments, zoom in and out, resize and shift the image. The push-buttons for these functions on the IR 601 work exactly like those on the VSC 150’s front panel. To function properly, the line of sight between the IR controller and the VSC 150 must be unobstructed.

The Power/signal lock LED blinks while the VSC 150 receives commands from the IR 601.

If the VSC 150 is set for Executive mode, adjustments can be made via the IR remote control.

All controls except Freeze will be locked on the IR 601 while Freeze mode is active. Press the Freeze button again to turn off Freeze mode and unlock the other controls.

Using the memory feature

In addition to performing the basic functions, the IR 601 remote control provides a memory storage and recall feature. The VSC 150 offers 30 factory-defined presets and 30 user-defined memory presets that store combinations of size, zoom, panning, centering and filtering settings. These settings are recalled automatically in association with a particular input signal scan rate.

The VSC 150 also offers three additional user-defined presets that can be recalled manually via IR 601 or RS-232 remote control.

The IR 601 has four Memory buttons for storing and recalling up to three presets. To store and recall combinations of settings with the IR 601, follow these steps:

1. Set the sizing/zoom, centering and filtering settings for the desired computer video source by using the front panel controls, RS-232 commands, or the IR 601 controls.

2. Press the Store button in the Memory area of the IR 601 control. The Power/signal lock LED flashes for 4 seconds. During that period, press the button labeled with the number (1, 2 or 3) corresponding to the desired memory. The image settings are stored in a user memory slot corresponding to that number. If the button is pressed after the LED stops flashing, the settings are not stored.

3. To recall a setup that has been stored in memory, press the appropriate numbered Memory button. The combination of zoom, sizing and filtering level settings are recalled.

The same three user-defined presets can also be saved and recalled using the RS-232 control. To store and recall these memory presets via RS-232 control, follow these steps:

1. Set the sizing/zoom, centering and filtering settings for the desired computer video source by using the front panel controls, RS-232 commands, or the IR 601 controls.

2. Use the memory commands in the Command/ response table on page 3-5 to save or recall the presets.
