Video to PC/HDTV Switching Scaler
1. Introduction
1.1 General
The TVB-400 is a multiple format switching video scaler. It has 4
different types of video inputs and a scaled output that can be switched
to any of the inputs.
Inputs are: Composite Video (NTSC or PAL), S-video (NTSC or
PAL), Component Video (SD and HD from 480p to 1080i), and a PC
(from VGA (640x480) to SXGA (1280x1024) for scaled output, or up
to 1920x1440 for pass thru video).
The output format and resolution can be specified by the user as either
PC (VGA (640x480) to SXGA (1280x1024)) or Component Video
(YPbPr from 480p to 1080i - a VGA to 3 RCA adapter cable is
included). The user can set the output to the optimal sweet-spot of
your display and let the TVB-400 handle and convert various kinds of
video inputs for your LCD.
The TVB-400A is the same as the TVB-400 but adds audio switching
and volume control capabilities (for line level audio).
The Video Scaler can be controlled in many ways including: front
panel lighted pushbuttons (with On-Screen Display menus), using the
included IR remote control, or RS-232 Serial interface. The controls
include: input switching, setting the output resolution, picture
adjustment (tint, color, brightness, contrast, and sharpness), aspect ratio
(Standard, 16:9 or 4:3), digital noise reduction, 3D comb filter On/Off,
volume control and many other advanced features.
The TVB-400 is ideal for use with in boardrooms, classrooms, digital
signage, and high end home-theater applications. Its output can be set
for any LCD projector, PC LCD monitor, plasma, or HDTV displays.
The unit is shipped with all the required cables and adapters, IR
remote, and also Windows® PC based RS-232 control software.

Video to PC/HDTV Switching Scaler
2. Installation
2.1 Connecting the Video inputs
The video scaler can accept a both TV and PC inputs and scale them to
your desired high resolution format output. The TV inputs are
composite video (BNC connector), S-Video (Mini-Din connector), and
an YPbPr input (3 BNC connectors). BNC to RCA adapters are
included for composite and component inputs. Both standard definition
TV (SD) and High Definition (HDTV) are supported. The unit also
provides a PC input that is also scaled for the output (note that PC
input can also be directly bypassed to the output without scaling if
desired). Refer to Figure 2.1 for a block diagram.
Rear Panel
S-Video: Use an S-Video cable to connect the S-Video output of the
source video equipment to the connector labeled “S-Video” on the
back of the Video Scaler. The format can be NTSC, PAL, or SECAM.
Composite Video: Use a Composite video cable to connect the
composite video output of the source equipment to the connector
labeled “Video” on the back of the Video Scaler. The format can be
NTSC, PAL, or SECAM.
YPbPr input: Use a 3 RCA-to-3 BNC YPbPr cable to connect the
YPbPr output of the source video equipment to the device. The format
can be NTSC, PAL, or SECAM.
Computer RGB with H&V Sync: Connect the source computer's
VGA output signal to the HD 15 connector labeled “PC In” on the
Video Scaler.

TV-to-VGA / HDTV Video Scaler
2.2 Connecting the Optional Audio Inputs (TVB-400A Only)
Each of the Audio input jacks are matched to a correspondingly labeled
video input connector. As each video input is switched, the audio input
is also switched. Each audio input has an associated volume level that
can be controlled from the front panel or via a RS232 command.
2.3 Connecting the Scaled Output
The output can be connected to any VGA compatible LCD, Projector,
or Plasma display. It can also output HDTV compatible YPbPr in
various formats as described below.
The same HD-15 connector is used to output VGA (RGBHV) output or
HDTV/YPbPr output. When VGA (RGBHV) outputs are selected
(VGA, SVGA, XGA, SXGA) use an HD-15 to HD-15 VGA cable to
connect the output to the PC input of your display monitor.
When HDTV/YPbPr outputs (480p, 576p, 720p, 1080i) are selected,
use a HD-15 to YPbPr 3 x RCA cable to connect the output to the
YPbPr input of you HDTV display. Both cables are provided. Connect
the Audio Output jack to the audio input of the display or sound
system.

4. Serial Control
The video input selection and signal parameter settings for the TVB400 can be controlled via an external control system by using the RS232 port on the unit. A free Windows® control software is available
that permits remote control of the unit from a PC via RS-232.
Use a straight thru M/F DB9 serial cable to connect the unit to the PC.
Only the TX, RX and GND pins are implemented in the connector. The
RS232 port operates at 9600 baud, no parity and 1 stop bit. Control
codes are 3 bytes long. In the table shown below, the 1
are ASCII and the 3

4.1 Control Software Installation
Ensure that any other software applications are closed before
attempting to install the software. Install the control software by
inserting the CD that comes with the unit into the CD drive.
• Run the “SETUP.EXE” program. The following screen is
displayed:
• Click the OK button and the following screen is displayed:
• Click the button to continue the installation into the default
directory. The default directory may be changed from this
screen if desired. The software installation will then copy all
the files to the desired destination.
• The following screen is then displayed:
• Click the OK button
11
4.2 Using the Control Software
TV-to-VGA / HDTV Video Scaler
• The first time the application software is run, you must select
the appropriate COM port that the unit is connected to. The
software will retain this information when executed in the
future.
• The AV Settings and Adjustment windows are by default not
displayed. Click the button to open or close the panel.
• The ‘PC Loop Bypass’ must be enabled (which is the default
setting) in order to bypass the PC IN signal to the OUT
connector. When the ‘PC Loop Bypass’ is disabled, the ‘PC
BYPASS’ button is grayed out and the selection disappears
from the OSD.
• On the TVB-400A, when ‘PC BYPASS’ is selected, the only
valid adjustment is ‘VOLUME’.
12
Video to PC/HDTV Switching Scaler
• The software is broken down into 4 basic groups of controls:
o Input
This is the Video Input source selection. PC Bypass is
only available when ‘PC LOOP BYPASS’ is enabled
in the ‘adjustment’ menu.
o Output
This is where the video output should be directed.
o AV Settings
These are the picture and audio volume control.
Clicking the ‘AV Reset’ button will change all of these
parameters back to there default settings.
o Adjustments
These are the various settings that allow you to control
‘Bypass’, OSD, Digital NR, 3D enhancement, aspect
ratio, Front Panel locking, Video blanking, Video
freeze frame functions or if the Remote Control IR
Sensor is enabled.
• As buttons are pressed on the unit, the control software will
mirror the settings as they are executed. Also as ‘buttons’ are
pressed in the control software, the OSD and units illuminated
buttons will change when appropriate.

5. Troubleshooting
There are no field serviceable parts or circuits in the device. If you
think that the device is malfunctioning, please first try to reset to
factory default settings:
5.1 Resetting the TVB-400 to Factory Defaults
To reset all parameters back to the factory preset value, press the
“Mode” and “Adjust” buttons simultaneously for over 10 seconds. The
‘Power’ led will turn off when the buttons are pressed and then turn on
again when the reset has occurred.
5.2 Contacting Hall Research
If you determine that your scaler is malfunctioning, do not attempt to
repair the unit. Contact the Hall Research Technical Support
department at 714-641-6607.
Before you do, make a record of the history of the problem. We will be
able to provide more efficient and accurate assistance if you have a
complete description.
5.3 Shipping and Packaging
If you need to transport or ship your Scaler:
• Package it carefully. We recommend that you use the original
container.
• Before you ship the units back to Hall Research for repair or
return, contact us to get a Return Authorization (RMA) number.
