Unpacking

Connections

The Video Titler package includes the following items:

TLR300 or TLR400 Video Titler Unit
DPD120050 or DTS120150 (optional) power supply
This operation manual

Please inspect all items carefully and report damaged or missing
items to your dealer or MicroImage Video Systems.

Power

The TLR300/TLR400 use an external +12VDC power supply. A
120VAC input adapter is included with the unit. An optional
universal power supply is available that accepts an input from 120
to 230VAC (this is an extra cost option). Connect the power
module to the Video Titler and to an appropriate power source.

Keyboard

Connect the keyboard to the connector labeled Keyboard on the
rear of the TLR300/TLR400 unit. Note the correct orientation of the
connector or damage can result. Do NOT connect or disconnect the
keyboard while the power is on. Damage to either device may
result. The TLR300 and TLR400 are compatible with most PS/2
style keyboards (those that have the smaller 6 pin Mini-DIN
connector). It will also work with many AT style keyboards and an
appropriate adapter, provided the keyboard does not draw too
much current (many older types will).

Video

Connect the video source (i.e. video camera) to the appropriate
INPUT connector on the rear of the Video Titler unit. Use the BNC
connector for composite or B&W (TLR300), the 4 pin connector for
S-Video (TLR300) and the 9 pin D-sub connector for RGB
(TLR400).

Connect the OUTPUT signal from the Video Titler unit to the video

displays as required. Each output can only have a single 75 ohm
termination. You must use the same signal type and connector for
output that was used for input.

If the signal must drive multiple monitors or other devices, please
see the documentation for those devices for multiple unit
connections. A Video Distribution Amplifier may be required,
especially for S-Video signals. MicroImage Video Systems offers a
variety of units for these applications (VDA series).

The MicroImage Video Systems Video Titler is designed for video
titling and captioning. It is particularly well suited to industrial,
medical and scientific applications.

The TLR300 and TLR400 can each generate up to 10 pages of text
with 32 (horizontal) by 20 rows of characters. Each character can
be 1 of 8 colors and each can have 1 of 8 background colors or
transparent.

The TLR300/400 may be configured either to insert text over a
video signal (Overlay) or to operate as a text display without any
incoming video source (Stand Alone). If no input signal is present,
the unit will switch into Stand Alone mode until a valid video signal
becomes available.

The Stand Alone mode of operation may be used to provide an
easily updated display from a remote keyboard location, either for
customer information, emergency instructions, advertisement, or
current schedules or prices. Up to ten pages of color text and
backgrounds may be created, then called up with simple key
commands.

The TLR300 and TLR400 can be operated from a +12VDC (11-20V)
power supply and each has a one year warranty.

The TLR300/400 may be ordered with an optional Battery Backup

Operation

module (Option BB), which will remember all ten pages of text
when power is turned off or in the case of accidental power loss.

The user may also create multiple pages of text, switch the unit
off, and remove the keyboard. The unit can then operate without
the keyboard, and be switched between the ten text messages by
using the front panel Page Up and Page Down buttons as needed.

The Video Titler has four switches and two LEDs on the front panel.
Most functions are set by use of the keyboard. Following is a brief
description of each switch and its functions:

Power Switch

The power switch is used to turn the Video Titler unit on or off.
When off, the unit draws minimal power. When on, the power light
will illuminate (green) and the Video Titler will be ready to use.

Display Switch

The display switch is used to enable or disable the titler display.
This will allow the video signal to pass through without the title
display. The blue indicator next to this switch will illuminate when
the display is enabled.

Page Up

The Page Up switch will display the previous page with each press
until the first page is reached. For changing pages, this switch
operates the same as the keyboard PgUp key. This switch is
provided for applications where the keyboard may be disconnected
from the main unit.

Page Down

The Page Down switch will display the next page with each press
until the last page is reached. For changing pages, this switch
operates the same as the keyboard PgDn key. This switch is
provided for applications where the keyboard may be disconnected

from the main unit.

Keyboard Functions

Most functions of the Video Titler are controlled through the
keyboard. See the next section on Using the Titler for additional
information.

TLR300/TLR400 Functions

The TLR300/400 Titler series has been engineered for a broad
range of applications. A variety of options and features may be
selected or changed either through the menu system or by way of
a combination of keystrokes. This section describes the use of the
function keys and menus. Most selections can be made either by
pressing the appropriate number key or by using the up and down
cursor arrows and then pressing the <ENTER> key. The <ESC>
key can be used to exit most menus without changing the current
settings.

Help Screen - <F1>

A HELP screen is available by pressing the <F1> function key on
the attached keyboard. This screen lists many of the common key
commands and function keys. You can switch to the second page
of this list by pressing the down arrow key. Pressing the <ESC>
key will return the unit to normal operation.

Color Options

Eight colors of text are available from the <F3> Foreground Color
menu, and eight background color tiles may be selected from the
<F4> Background menu. Any letters typed will appear on a
contrasting background tile which surrounds the letter. The unit
will not allow the user to select the same Foreground and
Background color, which would make the letters unreadable. A
transparent background is also available, which places the text
characters directly onto the video image or underlying color page.
If using a solid underlying page, the user can choose from eight

Page 9

page colors.

The color of each character and its background tile may be set
individually. Simple graphic shapes, outlines, and text boxes may
be created using color background tiles with blank spaces instead
of letters. The unit will remember the current foreground,
background, and page color settings while switched off.

Foreground Color - <F3>

Pressing the <F3> function key calls up a menu of 8 color choices.
Pressing the number key listed before each color will select that
color. Any text typed after this will use the new color. The key
combination of <SHIFT>+<F3> will change the current foreground
color to the next one on the menu without bringing up this menu
screen. Any text already typed will be unaffected by the changes.

Background Color - <F4>

Pressing the <F4> function key calls up a menu of 8 color choices,
plus transparent. Any text typed after this will appear on a
background tile of this color. If transparent is selected, any text
typed after this will appear directly on the video image or solid
color page. The key combination of <SHIFT>+<F4> will change
the current background color to the next one on the menu without
bringing up this menu screen. Any text already typed will be
unaffected by the changes. Note that some combinations of text
and background colors may appear ragged or blurred, particularly
while using composite video, mainly due to the way in which colors
are handled by the monitor.

Display Off - <F7>

Pressing the <F7> function key disables the text display overlay,
showing the incoming video image with no obstructions.

Display on - <F8>

Pressing the <F8> function key enables the text display overlay,
showing text and background color tiles in front of the video
image.

Cursor Off - <F11>

Page 10

Pressing the <F11> function key disables the flashing cursor for
readability and aesthetics. The cursor may be set from the main
menu to be either off or on whenever the TLR is powered up.

Cursor on - <F12>

Pressing the <F12> function key activates the flashing cursor to
indicate where any newly typed text will appear. This cursor may
be moved around the screen using the "arrow" or "cursor" keys on
the keyboard. The cursor will also reappear any time new text is
typed.

Main Menu - <F10>

The main system menu may be called up using the <F10> function
key. This menu allows access to a series of screens which control
the following functions of the TLR. Pressing the number key listed
before each item will bring up that menu screen. Pressing either
the <0> or <ESCAPE> keys will exit this menu and return the unit
to normal operation.

Color Bars

The Color Bars screen allows the user to display a color bar test
pattern instead of incoming video. This is useful for a basic
systems test when a camera or other signal source is unavailable
or inconvenient. Pressing the number <1> key while in the main
menu will bring up this screen. The current state (ON or OFF) of
the color bar display should appear highlighted. You may then
either press <2> (ON) to display color bars, or <1> (OFF) to
disable color bars and display the incoming video signal. Pressing
<0> or the <ESCAPE> key will exit the menu system without
changing any settings.

Operation Modes Sub Menu

The Operation Modes screen selects between Overlay and Stand
Alone modes. Overlay operation places text over an incoming
video signal, while Stand Alone is used to display text on a solid
background with or without a separate video source. The first
menu option allows the user to choose between the two modes.
The second menu item, Page Color, offers 8 solid page colors for
use in Stand Alone mode.

Page 11

The TLR300/TLR400 may be configured either to insert text over a
video signal (Overlay Mode) or to operate as a text display without
any incoming video source (Stand Alone Mode). If the unit does
not detect any input signal, it will automatically switch to Stand
Alone Mode (with solid background color), regardless of the
setting. As soon as a valid video signal is present, it will return to
Overlay Mode if it had been set for that mode.

When used in Stand Alone Mode, the units will still accept a video
input such as Black Burst to lock the unit to a specific time base.
This will eliminate cross monitor flicker if more than one display is
used side by side. This occurs automatically if an input is applied.

System Options Sub Menu

The System Options sub-menu brings up a list of other
configuration screens.

Color/B&W Mode

The first of these is the Color/B&W Mode screen, which may be
called up by pressing the number <1> key from the System
Options sub-menu. When color mode is selected, text and
backgrounds will appear using the colors selected by the
FOREGROUND and BACKGROUND functions. B&W mode should be
selected if the unit is to be used with a Black & White camera or
monitor, since the effects of color information on a Black & White
signal may be objectionable on some monitors. Colors selected
using the Foreground and Background color menus will appear as
shades of gray.

Power Up Cursor Mode

Pressing the number <2> key from the System Options sub-menu
calls up the "Power Up Cursor Mode" screen. This determines
whether or not the blinking cursor will be visible when the unit is
switched on. In situations where the text is edited frequently,
having the cursor visible may be convenient. Selecting "Power Up
Cursor Off" provides a cleaner display for the viewer in the event
of power loss or occasional shutdown. This menu will not affect
the cursor until the next time the unit is powered up.

Power Up Clear Memory

Page 12

This option is valid for units with option BB only.

Pressing the number <3> key from the System Options sub-menu
activates the screen entitled "Power Up Clear Memory". When
enabled, the titler will begin with a blank screen whenever it is
powered up. All ten pages will be cleared.

When "Do Not Clear" is selected on a TLR300/400 which has the
BB option installed, the unit will remember the text and colors in
the event of power loss or shut down. This screen will not have
any effect on units without the BB option, the screen will always be
cleared on power up.

Position Adjust

Pressing the number <4> key from the System Options sub-menu
selects the "Position Adjust" screen. While this screen is active,
the text display may be repositioned slightly by using the cursor
arrows on the keyboard. When the display is properly centered or
positioned, pressing the <ENTER> key will save the location.

System Info

Pressing the number <5> key from the System Options sub-menu
displays the "System Info" screen, which shows the current
product software revision number and manufacturer. Pressing any
key from this screen will exit the menu system and return the unit
to normal operation.

System Defaults Sub Menu

The System Defaults sub-menu allows the user to restore the unit
to factory default settings. Pressing <1> from this sub-menu
brings up the option "Clear All Pages", which clears the contents of
every page of the Character Generator text memory.

Pressing <2> from the System Defaults sub-menu calls up the
"Reset Factory Defaults" screen, which replaces all unit settings
with the original factory defaults. Both of these options have an
additional screen to verify the change, to reduce the likelihood of
accidental loss of user input or settings.
