Genlock connections
A genlock (black burst generator) device can be connected to the MVP 104GX via
the BNC connectors shown below. The genlock feature allows the MVP 104GX to
be synchronized with other system components for seamless vertical interval
switching between sources. See Setting Up Genlock and Vertical Interval Switching in
this chapter.

Setting Up Genlock and Vertical Interval Switching
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.
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 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.
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.
MVP 104GX Installation 2-7
Installation, cont’d
To synchronize the MVP 104GX’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.
2. Connect the active timing source signal to the Genlock In connector on
3. Connect the video input signals to the MVP 104GX, as described
4. Connect the oscilloscope (“scope”) probe A to the Genlock Out connector.
5. Connect scope probe B to the MVP 104GX’s composite video output

MVP 104GX Installation
Oscilloscope displays
What you see on the oscilloscope while adjusting the MVP 104GX 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 2-6 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.
Figure 2-6 — Superimposed waveforms
A vectorscope is more accurate than a waveform monitor. Figure 2-7 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 encoder
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.

MVP 104 Operation
Windows-based Control Program
The MVP and SVS Control Program (Extron part number 29-047-01), which is
used by the MVP 104GX, requires Windows 95/98, NT, or later. It provides
remote control of MVP 104GX functions.
Installing the Windows®-based Control Software
The program is contained on two 3.5-inch diskettes. The program occupies
approximately 1.5 MB (megabytes) of hard-drive space. Run the program
from the hard drive.
To install the software from the floppy disks onto the hard drive, run
SETUP.EXE from the first floppy disk, and follow the instructions that
appear on the screen.
By default, the Windows installation creates a C:\MVP+SVS directory, and it
places two icons (MVP+SVS Control Pgm and MVP+SVS Help) into a group
folder named “Extron Electronics”.
Using the Software
1. To run the MVP and SVS Control Program, double-click on the
MVP+SVS Control Pgm icon in the Extron Electronics group or folder.
The Comm menu appears on the screen.
MVP+SVS
Control Pgm
2. Click on the comm port that is connected to the MVP 104GX RS-232 port.
The Extron MVP and SVS Control Program main screen appears, as shown
below. The screen display includes controls for video inputs, audio inputs,
picture adjustment controls, and a graphic representation of the window
images.

adjustments as from the MVP 104GX front panel. The illustration below,
which shows the four input windows, is an example of the window
adjustment screen that appears after the Adjust Window button is selected
from the previous MVP and SVS Control Program main screen. The window
sizes, position, priorities, text, text placement, blanking around images, and
background colors can be adjusted from this window.

The MVP 104GX comes from the factory configured for RS-232. To set the
MVP 104GX for RS-422 operation, see “Configuring the MVP 104GX for
RS-422” in the appendix.
The RS-232/RS-422 connector is a 9-pin D female (see illustration above)

The protocol is 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control.
Commands and responses for programming the MVP 104GX from a host
system connected to the RS-232/RS-422 port are listed on the following
pages.
Host-to-MVP 104GX Communications
The MVP 104GX accepts SIS™ (Simple Instruction Set™) commands through
the RS-232/RS-422 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 MVP 104GX response to an SIS
command ends 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.
MVP 104GX-initiated messages
When a local event occurs, such as a front panel operation, the
MVP 104GX responds by sending a message to the host. The MVP 104GXinitiated messages are listed below (underlined).

MVP 104GX error responses
When the MVP 104GX receives an SIS command and determines that it is
valid, it performs the command and sends a response to the host device. If
the MVP 104GX is unable to perform the command because the command is
invalid or contains invalid parameters, the MVP 104GX returns an error
response to the host. The error response codes are:
E01 — Invalid input number
E09 — Invalid function number (too large)
E10 — Invalid command
E11 — Invalid preset
E13 — Invalid value (out of range)
MVP 104GX-generated unsolicited responses
Whenever there is a front panel operation (only), the MVP 104GX responds
by sending an unsolicited response (Reconfig##) to the Host. Use the 2 digit
code ## to locate the event below.
Reconfig00 = More than one window configuration changed
Reconfig01 = Window 1’s configuration changed
Reconfig02 = Window 2’s configuration changed
Reconfig03 = Window 3’s configuration changed
Reconfig04 = Window 4’s configuration changed
