4.0 CONNECTING THE HARDWARE
Please study the drawings below and become familiar with the inputs, outputs
and control locations on the AVT-3190HD.
AVT-3190HD Front Panel
The Power Button switches between “Standby” and “On”. When the unit is turned
on, the LED marked “On” above and slightly to the right of the power switch will
illuminate.
The Square window area to the right of the power switch is the location of the
Infrared sensor used by the remote to control the unit. It must remain unblocked
if the Remote IR unit is used to control the unit.

7
The Four buttons with the arrows are used to position and pan the image. The
Aspect button allows switching between wide screen and standard display
modes and the Overscan button allows magnification of the image.
AVT-3190HD Rear Panel
The inputs and outputs on the rear panel are clearly marked. Connect the
appropriate cables to the inputs making certain that the cables are in good
condition and undamaged. The power switch (Upper right on the drawing above)
removes or applies power to the unit. If the switch is in “Off” position, the power
switch on the front will have no effect since it is a Standby switch, not an actual
power switch. The Switch next to the power connector is used to switch between
PC input and HDTV input.
5.0 Operating the AVT-3190HD
Operating the AVT-3190HD is intuitive and easily learned. The operation at the
unit itself is accomplished via buttons mounted within the case. Although easily
learned, controlling the unit via these buttons is a rather limited way to operate
the unit because all functions are not available from these buttons.
Since virtually all users will operate the unit via the remote control to gain
complete control over its functions, it is recommended that you take the time to
discover where the various buttons are located on the remote by looking at the
actual remote and comparing it to the diagram above.
Like the manual controls on the unit, the labeling is clear for the majority of the
functions and the unit’s On Screen Display (OSD) will help clarify any confusion.
The pages that follow will magnify the remote’s control sections and explain each
function. Study the overall drawing and become familiar with the general layout of
the remote control. Refer to the descriptions that follow in this manual for detailed
information.

:
When the Zoom
button is pressed, the
picture is divided into
nine zones. Pressing
one of the numbered
buttons selects the
portion of the image
(the zone) you want
to enlarge.

10
The Four Buttons shown below––Zoom, Aspect, Pos/Pan and Size/Exp––
control picture manipulations and the arrowed buttons work in conjunction with
these four buttons to do the actual manipulations. The Default Button (in the
middle of the arrow button matrix) returns the following parameters to factory
presets: Zoom, Position, Size and Picture Adjustments. Descriptions of the
Zoom, Aspect, Pos/Pan and Size/Exp functions are shown below.
ZOOM:
As explained above,
this Button places the unit in
the Zoom mode and the
numbered buttons select the
portion of the image to be
zoomed. Once selected, the
arrowed buttons allow
zooming or movement across
the selected image.
POS/PAN:
If the unit is in
underscan mode, pressing
this button allows the user to
position the under-scanned
image anywhere on the
raster using the arrow
buttons. If the unit is in the
overscan mode, pressing
this button allows the user to
pan the over-scanned image
using the arrow buttons
ASPECT:
This button toggles
three modes. Full is the regular
4:3 aspect mode. The second
toggle activates the Pan and
Scan mode wherein you can
adjust the image horizontally and
vertically. The final toggle
activates the letterbox mode.
SIZE/EXP:
When in the
underscan mode, pressing
this button allows the arrow
keys to expand or shrink the
image within the monitor’s
raster. If the system is in
overscan mode, the arrow
buttons set the degree of
overscan.

11
Along the right side and bottom of the remote control there are several control
buttons. The functions are:
CONTRAST, BRIGHTNESS,
COLOR & SHARP: These buttons,
allow adjustments to be made to the
labeled signal parameters. Pressing
a button causes the arrow buttons to
become active and those buttons are
used to make the actual adjustments.
V-RESET: Restores Factory default
settings to the Contrast, Brightness,
Color and Sharpness parameters.
NTSC/PAL: Selects the television
standard to use on the unit’s output.
SYS-RESET: Restores Factory
Presets to all parameters. (Overscan,
NTSC, 4:3 Aspect, Signal
Parameters & CV/SV Output.)
COLORBAR: Causes an internally
generated color bar signal to appear
on the unit’s outputs.

5.1 RS-232 Operation
Software is included to allow control of the AVT-3190HD via a computer. The
operation under RS-232 control is explained below.
5.1.1 Installation of the Software (Windows 98/ME/2000/XP)
Place CD in appropriate drive and execute the setup.exe function from the
CD. (The computer will probably update some files causing the need to
reboot after the initial setup has finished. If this happens, reboot and run
setup a second time.)
Once fully installed, click the taskbar menu (Start>Programs>Scan
Converter) to start the RS-232 software.
5.2 Operation Under Control of RS-232 Software
A main panel will appear containing 19 icons that provide the control functions of
the unit (except icons 16 through 19). Click the icon to perform the function.
Refer to the list of numbers below to learn the function of the icons.

Selecting Zoom will cause a sub menu to appear where the actual adjustments
are made. The functionality is just like the remote control for the sub-panel
wherein the arrows and number matrix control the same things that the remote
control did. (The upward facing arrow at the lower right returns you to the main
menu.)
Selecting Position/Pan or Size/Expand will cause a sub menu to appear where
the actual adjustments are made. The functionality is just like the remote control
for the sub-panel wherein the arrows control the same things that the remote
control did. (The upward facing arrow at the lower right returns you to the main
menu.)
Selecting Video Settings on the main menu will call up another sub-panel where
the actual adjustment can be made. Clicking the “R” icon on this panel resets
these settings to Factory Default. Again, the upward facing arrow at the lower
right returns you to the main menu.

14
Clicking the Magnifier icon will call up a sub-panel that allows adjustment of
picture size. This only works when in the PC mode.
Clicking 1.5 magnifies the image 1.5 times. Selecting 2.0 results in a 2X
magnification. Clicking “S” generates an undersize image and B yields a ”Big”
frame. The two intertwined arrows call up an image refresh routine and the “X”
closes this sub-panel.
There are two other sub-panels available:
Clicking Option causes the following sub-panel to appear. (Click on the desired
action.)
Finally, the last sub-panel displays software and firmware information. Click the
About icon to call up this display:
Again, the upward facing arrow at the lower right returns you to the main menu.

RS-232 Codes
RS-232 Code Implementation:
All Command and Response codes are six (6) bytes.
For every Command, the response is the same code.
Only PWR*** & VER*** codes are available when the unit is in the powered
down status (where *** are the last three bytes of the six byte code group).
Some commands result in a wait state wherein no additional commands will
be accepted until the unit issues a RDY*** response.
Data Protocol:
Baud Rate: 9600 bps
Data Bits: 8 Bits
Parity: None
Stop Bits: 1 Bit
Note:
Some commands require more time to execute than others. Any user written RS-
232 control program should include processing of the echoed Response codes
before attempting to execute a new command to avoid data collisions.
RS-232 Codes
The following table contains the six byte code groups, the RDY*** codes (where
relevant) and a comment section that provides plain text descriptions of the
action that will be taken by the AVT-3190HD when given the codes.Make certain
that the data structure is as specified when using the RS-232 capability.

6.0 TROUBLESHOOTING
Other than checking for faulty cables, the only common problem would be
choosing a wrong Output Setting. Make sure the AVT-3190HD is capable of
handling the resolution and refresh rate selected and make sure the output
format selected (Composite, S-Video or YCbCr) is correct for the type of cable
and connector being used at the output. Also make certain that you have
selected the correct television standard (NTSC or PAL). After trying the above
suggestions should the problem still persist, contact your dealer for additional
suggestions before contacting TV One. Should the dealer’s technical personnel
be unable to assist you, contact TV One via our support website:
http://tvone.crmdesk.com. Create a technical support request on the site and
our support team will respond within a short period of time.
