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
•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 (SIS™) 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.

h 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.
i 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.
VSC 500/700/700D User Guide • Installation and Operation5
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.

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.
6. 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.
7. 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).
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. Once the settings are stable, disconnect the oscilloscope, and reconnect the genlock
cables.
10. Check the displays for proper colors and for undesirable artifacts in the images. Make
adjustments as necessary.
11. If other VSCs are part of this genlock daisy chain, connect the oscilloscope to each
device, and repeat this procedure.
VSC 500/700/700D User Guide • Installation and Operation6
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.

NTSC Composite
Output Signal
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.
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 0º. This example shows black burst
only (with no color). The burst vector is pointing to the left from the center.

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 =
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).

VSC 500/700/700D User Guide • Serial Communication22
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

VSC 500 remove cover.eps
VSC 700 remove cover.eps
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.
2. 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.

3. Locate the U29 firmware chip to be replaced on the circuit board, as shown in the
VSC 700 replace chip.eps
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.
4. 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.

5. Insert the hooks into the slots, and squeeze the tool gently to grasp the chip.
6. Pull the chip straight out of the socket, and set it aside.
7. Align the slots of the new firmware chip with the angled corners of the socket in the
same orientation as the old chip.
8. Gently, but firmly, press the chip into place in the socket.
9. 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).
