Please inspect all items carefully and report damaged or missing
items to your dealer or MicroImage Video Systems.
Power
The TLR300/TLR400 use an ex12VDC 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).

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
