Introduction

About the VSC 500/700/700D

The Extron VSC 500, 700, and 700D are computer-to-video scan converters that can convert computer images up to 1920 x 1200 for output as composite video, S-video, component video, SDI (VSC 700D), and/or RGB video. Applications include videoconferencing, video recording, and viewing of images on an NTSC or PAL monitor or other display device.

Key features include automatic setup of centering and sizing controls, horizontal filtering, an LCD window for user-friendly menu selections, memory presets (IR remote control feature), and a buffered loop-through for local monitor output. The VSCs can be controlled via the front panel, the optional IR remote control, or RS-232 commands.

Features

• Autoscanning — Automatically recognizes and down converts the incoming computer image, up to 1920 x 1200 resolution and 100 kHz horizontal and 120 Hz vertical scan rates.
• Input — Via a 15-pin HD female VGA connector (VSC 500) or BNC connectors (VSC 700/700D).
• Outputs — Simultaneously outputs RGB or component video, composite video, S-video, and SDI (VSC 700D).
  • Memory presets — Recall up to eight user presets that can be stored and accessed via the optional IR remote.
• Auto-Image™ setup — Automatic sizing and centering function to fill the output display screen.
• Centering and sizing and controls — Allow for user-friendly positioning and sizing of the image on-screen.
• Freeze/Reset button — The freeze function locks the output display to the current image.
• Front panel security lockout — Locks out all front panel functions except centering (shifting) to prevent accidental changes to adjustments.
• RS-232 remote control — An RS-232/RS-422 control port utilizes the Extron Simple Instruction Set (SISTM) of basic ASCII commands.
• Genlocking (VSC 700 and VSC 700D only) — Allows for the synchronizing of multiple input devices to a common external timing signal so that the switch between input devices will be clean.
• Horizontal filtering — Four selectable horizontal filters prevent aliasing or pixel elimination so that less detail is dropped when the image is scanned from left to right.
• Buffered loop-through — Provides a local monitor output, enabling the computer input signal to be monitored without the need for a separate distribution amplifier.

⑧ Genlock input and output connectors — Connect an external blackburst signal to the input (In) female BNC connector for genlocking the video signal in broadcast or other sync-critical applications.
Connect any downstream equipment, which requires genlocking, to the output (Out) female BNC connector to route the blackburst signal throughout the system in broadcast or other sync-critical applications. See Genlock and Vertical Interval Switching.
⑨ SDI (serial digital interface) connector — Connect an SDI signal to this female BNC connector.

Genlock and Vertical Interval Switching (VSC 700 and 700D only)

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 it can also be passed to another device via the Genlock Out connector.

If the genlock connectors are used only for vertical interval switching, no horizontal or subcarrier phase adjustments are required.

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 horizontal signal 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 results in incorrect colors or picture artifacts.

To synchronize the video output of the VSC with a genlock signal, follow these steps:

NOTE: 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.

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.

3. Connect the video input signals to the VSC, as described previously in this section.

4. Connect the oscilloscope ("scope") probe A to the Genlock Out connector. This will provide the reference signal of the scope. 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 genlock output of the VSC.

Timing Source 75 ohm Terminator To Scope Probe B 75 ohm Terminator To Scope Probe A

1. Connect scope probe B to the composite video output connector (VID) of the VSC. 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 composite output of the VSC as shown in the previous diagram.
2. Using the instructions for the scope you are using, set the scope to view the horizontal phases of the signal. Adjust the horizontal phase by rotating the Adjust horizontal (◀) knob (see the "Genlock Menu" section in this chapter). Adjust the horizontal phase until there is no (0°) difference between the composite video output's horizontal sync phase and the genlock signal's horizontal phase. See the "Oscilloscope Displays" section.
3. Set the scope to view the subcarrier signals. Adjust the sub phase by rotating the Adjust vertical ( ) knob until there is a zero phase difference between the genlock signal and the NTSC/PAL output (see the "Genlock Menu" section).
4. View the horizontal phases again. If the phase difference is not zero, repeat steps 6 and 7 until the settings do not change.
5. Once the settings are stable, disconnect the oscilloscope, and reconnect the genlock cables.
6. Check the displays for proper colors and for undesirable artifacts in the images. Make adjustments as necessary.
7. If other VSCs 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 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 following diagram 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.

Genlock Input Signal NTSC Composite Output Signal

Figure 5. Superimposed Waveforms

With this method there is no way to know if the signals are 180^ 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.

A vectorscope is more accurate than a waveform monitor. The following diagram shows an example of a vectorscope display when the horizontal phase is adjusted to align it with the burst (genlock) vector. Adjust the horizontal phase by rotating the Adjust horizontal (◀▶) knob until the difference between the two vectors is 0^ . This example shows black burst only (with no color). The burst vector is pointing to the left from the center.

Troubleshooting

The image should appear 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.
3. Check the cabling, wiring, and grounding, and make adjustments as needed.
4. To test the system setup and output, substitute a video test generator for the computer input.
5. Confirm that the input is receiving a signal with a compatible scan rate (horizontal frequency between 24 kHz and 100 kHz, and a vertical frequency of 50 Hz to 120 Hz).
6. Call the Extron customer support hotline if needed. Be prepared to discuss the steps you have taken and the equipment involved.

If the image does not display correctly

Symptoms	Solutions
The picture is shifted off the screen edges.	Adjust the centering and sizing controls (◀,▲).
The picture appears without color.	Adjust the hue/ tint/ color controls on display device.Make sure that the video display/ recording equipment is using the same standard (NTSC or PAL) as the VSC.
In a genlocked system, displayed color is incorrect.	The color subcarrier phase (Sub Phase) might require readjustment.
The image still does not display correctly.	Call the Extron customer support hotline.

If the scan converter does not respond to controls

Symptoms	Solutions
The picture does not move on screen when the horizontal and vertical centering controls are rotated.	The VSC may be set for executive mode. Adjustments can be made via RS-232 control, or executive mode can be disabled by simultaneously pressing the Next and Size buttons for 2 seconds.
The VSC responds to adjustments made via the front panel, but not to selections from the IR remote control.	Signals from the IR remote control may not be reaching the VSC. Change the placement of the scan converter so that the IR signals have a clear transmission path between the remote control and the VSC.
There is no response to commands from the RS-232 controller.	Ensure that the baud rate (9600 baud) and communication protocol are set correctly.

VSC Infrared Remote Control

The optional VSC IR remote control, shown at right, replicates all of the front panel controls except the Menu and Next buttons. If Executive mode has been enabled on the VSC, input selection and adjustments can still be made from the remote control or the Windows-based control program (via an RS-232 device) to configure the video scan converter (see "Serial Communication" for details).

The topmost part of the remote control features the Horizontal filter buttons, a Freeze On and Off button, and the Vertical filter buttons.

Select input 1 or 2 via the Inputs buttons.

The middle portion of the VSC remote control features the Size and Shift buttons.

The bottom portion of the remote control features Presets 1 - 8. The presets save the input rate, the output type, sizing, shifting, and filtering information. After properly setting up an image, press the Store button, then press a preset button to save the settings to the selected preset button. To retrieve a preset, press the desired preset button.

Use the Zoom button to zoom in and zoom out of an image.

NOTE: The presets feature is only available through the IR remote control. For a detailed description of the other VSC features and functions that are accessed by the remote control, see earlier sections of this chapter.

Serial Communication

The VSC 500, 700, and 700D can be remotely controlled via a host computer or other device (such as a control system) attached to the rear panel RS-232/422 connector. The control device (host) can use either the Extron Simple Instruction Set (SISTM) commands or the graphical control program for Windows.

The video scan converter uses a protocol with:

9600 baud
- 1 stop bit
- no parity
- no flow control

The rear panel RS-232/422 9-pin D connector has the following pin assignments:

Pin	RS-232 function Description

RS-232 Programming Guide

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

Video Scan Converter-initiated Messages

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

(C) Copyright 2002, Extron Electronics, VSC 500, Vx.xx ← The VSC sends the copyright message when it first powers on. Vx.xx is the firmware version number.

Error Responses

When the VSC receives a valid SIS command, it executes the command and sends a response to the host device. If the video scan converter 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:

• E01 – Invalid input channel number (the number is too large)
• E09 – Invalid function number (the number is too large)
• E10 – Invalid command
• E13 – Invalid value (the number is out of range/too large)

Using the Command and Response Tables

The command and response table lists valid command ASCII codes, the video scan converter's responses to the host, and a description of the command's function or the results of executing the command. Lower case characters are acceptable in the command field unless otherwise indicated. The following ASCII to HEX conversion table is for use with the command/response table.

Symbol Definitions

X10	= Picture adjustment range(see the note below)	← = Carriage return (hex ∅D)● = Space
X11	= Filter adjustment range (0 - 3)	X1 = Horizontal and vertical frequencies(listed to two decimal places, that is xx.xx)
X14	= Adjustment range (0 - 127)
Esc	= Escape key
←	= CR/LF (carriage return/line feed)(hex ∅D ∅A)	X2 = On/off status where: ∅ = off/disable, 1 = on/enable

NOTE: The default value for horizontal and vertical size is 0512. The default values for the horizontal and vertical shift are 2048 and 1024, respectively. The actual minimum and maximum values will vary and are based on the incoming scan rate.

Firmware Upgrade Chip Installation

In some cases the VSC firmware may require replacement with an updated version. There is one user-replaceable firmware chip: U29 — the main microcon troller. The number is printed on the circuit board. We recommend that you send the unit in to Extron for service and updates.

WARNING: Changes to firmware must be performed by authorized service personnel only.

Follow these steps to replace firmware in the VSC.

1. Disconnect the AC power cord from the VSC to remove power from the unit.

WARNING: To prevent electric shock, always unplug the VSC video scan converter from the AC power source before opening the enclosure.

Remove the scan converter from the rack or furniture.

1. Remove the cover of the VSC (the top half of the enclosure) by removing the screws, sliding the cover back, then lifting the cover straight up.

Remove (8) Screws Slide cover back then lift straight up. VSC 500 Remove (6) Jack Screw Nuts. Remove (3) Screws from Back Panel.

Remove (8) Screws Slide cover back then lift straight up. Remove (2) Jack Screw Nuts Remove BNC Hex Nut Remove (9) Screws from Back Panel VSC 700D

Figure 31. Top Cover Removal

1. Locate the U29 firmware chip to be replaced on the circuit board, as shown in the following illustrations.

CAUTION: Do not touch any switches or other electronic components inside the VSC. Doing so could damage the video scan converter. Electrostatic discharge (ESD) can damage IC chips even though you cannot feel it. You must be electrically grounded before proceeding with firmware replacement. A grounding wrist strap is recommended.

1. After you are electrically grounded, removal of the U29 IC chip requires a PLCC IC puller tool. To remove the U29 chip, align the hooks of a PLCC IC puller tool with the slots located in opposite ends of the firmware chip.

Figure 32. Chip Removal

1. Insert the hooks into the slots, and squeeze the tool gently to grasp the chip.
2. Pull the chip straight out of the socket, and set it aside.
3. Align the slots of the new firmware chip with the angled corners of the socket in the same orientation as the old chip.
4. Gently, but firmly, press the chip into place in the socket.
5. Replace the top cover and secure it with the screws removed in step 2.

Mounting the VSC

Select tabletop placement or rack mounting. Follow the appropriate installation instructions on the following pages.

Tabletop or Desktop Placement

For tabletop or desktop placement only, install the self-adhesive rubber feet/pads (provided) onto the four corners of the bottom of the enclosure.

Rack Mounting

Underwriters Laboratories Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of these products in a rack:

Elevated operating ambient temperature — If the unit is 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 equipment in an environment compatible with the maximum ambient temperature (Tma: +122 °F, +50 °C) specified by Extron.

Reduced air flow — Install the equipment in the rack so that the equipment gets adequate air flow for safe operation.

Mechanical loading — Mount the equipment in the rack so that uneven mechanical loading does not create a hazardous condition.

Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Give appropriate consideration to the equipment nameplate ratings when addressing this concern.

Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).

Rack mounting procedure

1. If feet were installed on the bottom of the VSC, remove them.

2. Place the scan converter on one half of the 1U (one unit high, one unit wide) rack shelf (part number 60-190-01). Align the front of the VSC with the front of the shelf, and align the threaded holes on the bottom of the VSC 500/700 with the holes in the rack shelf.

3. Attach the VSC to the rack shelf with the two provided 4-40 x 1/8 inch machine screws. Insert the screws from the underside of the shelf, and securely fasten them into diagonally opposite corners, as shown in the following illustration.

False Front Panel Uses 2 Front Holes Use 2 Mounting Holes on Opposite Corners (2) 4-40 x 3/16" Screws

Figure 33. Rack Shelf Mounting

1. Attach the false front panel (provided with the rack shelf) to the unoccupied side of the rack (as shown above), or install a second half-rack width device in that side by repeating steps 1 - 3.

2. Attach the rack shelf to the rack using four 10-32 x 34 inch bolts (provided). Insert the bolts through #10 beveled washers, then through the holes in the rack ears and rack, as shown above.
