2.1 UNIT INSTALLATION
2.2 TV Signal
Connect an RCA cable from the
video out
connector, located on the bottom right of the
unit, to the video in of your TV. Use another
RCA cable to connect the
video in
connector,
located next to the video out connector, to
a standard unmodulated video signal. One
common example of this is the video output
of a VCR.
2.3 Power/ Keypad signal
The RCA cable from your keypad or display
carries both power and signals. It is imperative
that it is only connected to the power input.
Connection of the power cable to either video
input will likely destroy the unit. Connect the
9x0 power/signal cable to the
power input
on
the top right of the unit.
2.4 Power-up
Once power is applied to the unit (by turning
on the keypad driver) is will generate a video
output. If no signal is present at the video in-
put, it will generate a blue screen. Otherwise
it will pass the video through to the TV.
2.5 Con! guration
The mode button allows the user to adjust the
horizontal and vertical offset of the numbers on
the screen. This is done by pressing the mode
button, then using the plus and minus buttons
to adjust the setting. When done press the mode
button until the display is cleared.

OPERATION
3.1 Changing the Number Position
As a convenience to the viewer, an auxiliary input
button is provided. This allows the viewer to move the
number position to any of the four corners of the screen.

be moved to another part of the screen by pressing the
included button. Using additional cable, this button can
be run to a convenient location in the establishment.
3.2 Changing the Number Offset
The distance of the number from the edge of the screen
can be adjusted using the mode button. Press the mode
button once to activate the horizontal position adjust-
ment. Use the plus '+' and minus '-' buttons to adjust
the position. Press the mode button again to adjust the
vertical position. Press the mode button a third time to
return to normal operation.
3.3 Status Lights
There are two lights visible on the top of the case.
The video signal indicator lights when there is no video
signal detected. The power light fl ashes under normal
operation.
FAQ's
Q: Why can't I use just one unit for all my TV's?
A: The Model 190 does not have a built in tuner. It
requires an unmodulated video signal, such as the video
out from a VCR. Since the video signal is tuned to one
channel before being fed to the unit, it can only operate
on that particular video feed. Thus, a unit is required
for every video feed to a TV or bank of TV's.
