OPERATION SOFTWARE
System Requirement and Precautions
1. After turning off the DVP14; please wait at least 15 seconds to allow the power capacitors to be discharged
before reapplying power.
2. The DVP14 comes with a software control program which runs under Microsoft Windows 98, 2000, XP. The
application controls the DVP14 through a RS-232 serial data control interface.
3. Before you run the software please, make sure you have a RS-232 cable connected between your computer
COM port and the DVP14.
4. To make sure all information shown in the software display is synchronized with those in the device; please click
"Connect" to acquire the latest data from the DVP14.
Instructions for Software Connection
1. Turn on the DVP14. The front panel Display will be blink one time. Make sure the serial port (RS-232) connection
is secured.
2. The first step after running the software is automatic detection of the DVP14. If the DVP14 responds correctly
through RS-232 port, the computer will show the main control panel. The process takes 5 to15 seconds.
If the response is not accurate, a warning window will show up as follows.
There are a couple of possible reasons causing the lack of communications:
The DVP14 is not powered on.
The DVP14 been ON with no activity for a long period of time and may enter a sleep state. Please check the
current status, and reboot the DVP14.
The RS-232 cable maybe loose or some other software has taken the available serial port. Please make
sure the RS-232 cable is connected and the available serial port is free to be used by the DVP14 software.

Setup Individual Output DVI ports (Channel)
There are a total of 4 DVI output ports for the DVP14. Each DVI output can be independently set up
to display any area of the input video. Each output can be set to a different output resolution to adapt
different combinations of monitors or projectors.
To select each individual DVI output port to setup with preferable output, please
click on the desired output as shown to the left, and the control dialog window
shown below will show up accordingly!
For each output display, users can define which area of the input video is to be displayed on that
screen. First, setup the X Total and Y Total, and then define the upper-left (X Start, Y Start) and
bottom-right (X End, Y End) corners for each display channel. The control panel to achieve this goal is as
shown.

This screen representation area will demonstrate the resulting selection of the input video to be
displayed for the selected DVI output port.
“Original Input Video” shows the resolution information of the input video to each output channel,
and it will vary depending upon the input video.
“Selected Area” shows the information of the selected area to be displayed. The numbers will vary
according to different settings.
“Output Resolution” Section
Setup the output resolution for individual DVI output port. Notice that each display can run at a
different resolution to adapt to different resolutions from different panels.
Check “Capture Mode Enable” will enable the scaling parameters. This monitor will now display the
video region as defined by the output scaling parameters. If users disable this selection, this output
channel will display simply the full display of the input video.
Check “Auto Apply Settings” will automatically load the new settings into processor.
Select “Update Status” will refresh the information of the output video parameters.
Select “Update Apply Settings” will load the parameters into processor.
While “Auto Apply Settings” is checked, parameter updates are automatically sent to the processor.
Define Area Setting –Select the X Total, Y Total, Upper-left X, Y point coordinates using scroll bars
or manually keying in this section accordingly. This section will roughly define capture area for the
input which is needed for each individual channel. The resulting capture area corresponds to the
input video will be illustrated in the screen representation area .
“Fine Tune by Percentage” will provide the option to further adjust the position and area defined
in .
For outward expansion For inward reduction
By percentage, users need to determine what will be the reference. There are two choices for this
part: “Specified Area” and “Full Input”. Normally, “Specified Area” will work more appropriately
while users are dealing with panel bezels; because the overlapped masking area will be close the
specified area instead of full input video!
“Fine Tune by Pixel” offers similar approach to adjust the position and area of the output channel.
The idea behind this section is the same to “Fine Tune by Percentage”. The difference is that the
adjustment is based on pixels. Users can therefore adjust the output channel area pixel wise.

TROUBLESHOOTING
Problem
Recommendations
No power
Check the AC power cord to ensure proper insertion into the DVP14
and at the wall socket. If using a power strip, verify switch is on and
the circuit breaker is not tripped.
If you are recovering from a power outage or intentional AC power
disconnection, leave the device off for a minute and then power it on
again.
No or Erratic
Video
Make sure all cables are in good condition and properly connected to
the DVP14, the sources, and the displays.
Configure the output video resolution so that it does not exceed the
native resolution of the display. ( in this case, the message of “out of
range” is usually showed on your display screen)
Every time when you change the input resolution, 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 VGAinput is used for the first time, it will take up to 10 seconds
to display the VGA source successfully.
Poor quality
We suggest that don’t use Y-cables to split your video source. That
will lower output video quality. Use a distribution amplifier instead of
Y-cables.
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.
No Data
Connection
When unable to achieve serial port connection, please reboot the
DVP14. If this does not fix the issue, check the configuration of the
computer serial port and verify the serial cable is connected properly.
