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.
