INTRODUCTION
The
VW-1312 12-Display Dual-View Cascadable Modularized Videowall Processor
most cost effective, and fully real time data/video processor for multiple flat panel displays or projectors.
VW-1312 can support up to 12 DVI outputs to expand the spectrum of video wall applications. With add-on
card design concept, users can therefore to adjust the number of output ports based on different scenarios.
Meantime, with the very same chassis of VW-1312, the bandwidth of the video, the controllability of the
module, and the input complexity can be further explored to either cost down the project cost or enhance
with the new features from the new I/O cards.
Thru DVI transmission, the quality of the outcome videos is guaranteed. The output display is grained
up to 255 by 255 squares. Virtually any setups for the display layout can be possible by the provided
software. The VW-1312 allows you to manipulate two input videos, wherever positions and whatever sizes
you want for viewing. The embedded scaler converts signals from two of the input sources to match the
native resolution of monitors, flat panel displays, projectors as well as user-selectable output settings up to
WUXGA (1920x1200). The VW-1312 sends the resulting mixed video thru DVI interface to the connected
monitors/projectors based on the display layout. The layout can be readily modified to fit your applications
and optimize visual effects. Typical applications include digital signage, and broadcasting/education/
surveillance systems etc.

INPUTS AND OUTPUTS
The VW-1312 has five inputs (HDMI, DVI, Composite, Component, VGA) and accepts both graphics
and video signals, which come from computers and NTSC / PAL video sources respectively. There is a
concept of main channel and sub channel for this device. You can pick up one of the digital inputs and
one of the analog inputs, and then VW-1312 will display the mixed video on the connected 4 displays.
With an advanced de-interlacer built in, low resolution but popular video formats such as NTSC / PAL will
be improved. Figure shows the rear panel connectors for the video inputs of a VW-1312 and Table
illustrates how you can connect video devices and display to VW-1312.

2. When connecting other products such as DVD players, and personal computers, you should turn off
the power of this product for protection against electric shocks.
3. The product should be placed more than one foot away from heat sources such as radiators, heat
registers, stoves, and other products (including amplifiers) that produce heat. In addition, do not cover
any material or devices on the top of the device.
4. Do not use immediately after moving from a low temperature to high temperature, as this causes
condensation,
5. Do not place this product on an unstable cart, stand, or table. The product may fall, causing serious
injury to a child or adult and serious damage to the product.
6. Unplug this product from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners.
Use a damp cloth for cleaning.
7. Do not allow the same still picture to be projected for a long time or an abnormally bright video picture
to be projected. The video image could be burned in to the display device.
Installation Procedures
Unpacking
Remove the VW-1312 from the shipping container and examine it for any signs of shipping damage
or missing items (check with package contents above). All shipping items should be saved if the product
is to be moved or returned for service. Shipping unit back to dealers for service not in the original box may
result in voiding warranty or additional cost.
Placement
The unit uses convection to cool. A fan is not needed, so do not block the sides of this device or stack
another device on the top or bottom of the VW-1312.
Connections
We recommend the highest quality cables for both input and output connections.
1. Switch off the VW-1312 and all devices that you want to connect.
2. Connect 4 monitors, projectors or other displays that comes with DVI inputs by using male-to-male
DVI cables to VW-1312 DVI outputs.
3. Connect a device equipped with DVI output (such as PC) to the DVI input connector of VW-1312.
4. Connect your computer with the VW-1312 by a 9-pin RS-232 adapter and then install the software.
5. Power up the VW-1312.
6. Switch on all devices connected and then control the display output through RS-232 and software.

OPERATION SOFTWARE
System Requirement and Precautions
1. Whenever power off VW-1312, please stay unpowered at least 5 to 10 seconds to allow power
capacitors to discharge.
2. The VW-1312 provides a software control program which runs under Microsoft Windows 98, 2000, XP
through the interface of RS-232 serial control.
3. Before you click on the icon of the software, make sure you have secured the connection between
your computer COM port and the VW-1312.
4. The VW-1312 provides software control. To make sure all information shown in the software is
synchronized with those in the device, please click "Connect" to acquire the latest data from the
VW-1312 after you press any key on the remote control.
Instruction of Software Connection
1. Power up the VW-1312 and you can see Vacuum Fluorescent Display (VFD) on the front panel blinks.
Make sure the serial port (RS-232 or RS-485) connection is secured.
2. The first step after running the software is to automatically detect if the device responses correctly
through RS-232 port. The process takes 5-15 seconds. If the response is not accurate, a warning
window will show up as the figure below.
The possible reasons causing this failure could be:
The VW-1312 is not supplied with power or the VW-1312 enters deep sleep state. Please check the current
●
status, and reboot the VW-1312.
The serial connection through RS-232 is not well established or some other software has taken the available
●
serial ports. Please make sure the RS-232 cable is well connected and the available serial port is free to be
used by the VW-1312.

Setup Individual Output Channel

There are totally 4 channel outputs for VW-1312, and each output can be independently setup to
display any area of the input video. Each output can be with different output resolutions to adapt different
combinations of monitors or projectors.
To select each individual output to setup with preferable output, please click on the
desired output, and the control dialog window will show up accordingly!

For each display, users can define which area of the input video is to be displayed. Fundamentally,

TROUBLESHOOTING
Problem
Recommendations
No power
Check if you firmly plug the AC power core into the VW-1312
If you are recovering from power outage, accidentally unplug the
adapter or other power surge conditions, leave the device off for a
while and then power it on again.
No/Erratic video
Make sure all cables are in good working condition and properly
connected to the VW-1312 and displays.
Configure the output video resolution so that it doesn’t excess the
native resolution of the display. ( in this case, the message of “out of
range” is usually showed on your screen)
Every time when you change the resolution of input, please wait for
10-20 seconds. After the resolution is changed, the selection of input
and the Display layout mode will return to default. So, please adjust
the input source and Display layout mode to your requirement once
again.
When first time catching VGA input, it has to take 10 seconds to
display the VGA source successfully.
Poor quality
We suggest that don’t use T-connectors to split your video source into
to images displayed on two different screens. That will lower output
video quality. Use a distribution amplifier instead of T-connectors.
Make sure the video source is not compressed and maintains the
highest native resolution.
Wrong color
Press “Color Balance” key in “State” for auto configuration.
Auto color configuration only works at VGA and component inputs.
Poor Linking
When the linking of the serial control cannot work, please reboot
VW-1312.
