Introduction, cont’d 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.
Introduction, cont’d horizontal and color subcarrier signals. Genlocking provides for seamless vertical interval switching between the scan-converted signal and signals from other video sources. VGA or Macintosh input and local monitor output — The 15-pin HD and 15-pin D connectors allow easy connection to a PC or Mac local monitor. The included male Mac-VGA cable connects the VSC 150 to the computer without need for additional adapters.
Installation and Operation, cont’d Installation and Operation Installation Overview To install and set up the VSC 150, follow these basic steps: 1 Turn all of the equipment off. Make sure that the source computer, the VSC 150, the output devices (projector, monitors), genlock device (black burst generator), and remote control devices are turned off and disconnected from the power source. 2 Mount the scan converter. See “Mounting the VSC 150” in this chapter.

Executive mode prevents unauthorized or accidental adjustments to the VSC 150’s settings via front panel controls by locking all the front panel features except centering controls. Adjustments can still be made via RS-232 control or IR remote control when Executive mode is active.
Installation and Operation, cont’d See Freeze control (3) for information on using Executive mode. 12 13 Size control LED — This LED lights green to indicate that the size feature is active. Vertical ( ) and horizontal ( ) Centering/Pan/Size rotary controls — Turn these knobs to adjust vertical or horizontal centering (when the image size does not exceed screen size) and panning (when the image size exceeds the screen size) in the regular mode.
Installation and Operation, cont’d 2 — 75 Ohm (video input termination) — This switch provides a way to prevent blooming when no local monitor or termination adapter is connected. switching between sources. See “Cabling” and “Setting Up Genlock and Vertical Interval Switching” in this chapter. ON — The VSC 150 provides 75 ohm video input termination. Select this setting when a local monitor is not used. OFF — The VSC 150 provides high Z (high impedance) video input termination.
Installation and Operation, cont’d 3. Set the PAL Out (NTSC/PAL output) DIP switch. Use “Rear Panel Features” in this chapter as a guide. 4. Connect the composite video display or recording device to the composite video output BNC connector. 5. Select the format of the second output by setting the output selection toggle switch. 6. Connect a cable from the input of the second video display/recording device (projector, monitor, VCR) to the appropriate VSC 150 rear panel output connectors.

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. 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.
Installation and Operation, cont’d 10. 11. 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. shows black burst only (with no color). The burst vector is pointing to the left from the center.
Installation and Operation, cont’d are set for the formats that match the cable configuration and the requirements of the display/recording devices. 4. Verify that the 75 Ohm video input termination DIP 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 70 kHz, and a vertical frequency of 50 Hz to 120 Hz). 7.

Remote Control, cont’d 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.
Remote Control, cont’d 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.
