Introduction
Overview
The Video (+Audio) Splitters series broadcast the same video (+Audio)
signals from one video (+Audio) signal source to 2 / 4 / 8 DVI or HDMI
compatible outputs or monitors respectively, and the broadcast can be
expanded significantly when several splitters are cascaded together.
Depending on the length and cable quality, this fully HDCP compliant
splitter supports DVI / HDMI display resolutions of up to Full HD (1920 x
1080) / WUXGA (1920 x 1200) / UXGA (1600 x 1200), and is also Blu-ray
ready. There is no need for software or interface card installation. Just
connect the cables, power up the system and you are ready to have
duplicated video images for multiple monitors with excellent clarity.
Moreover, 4 / 8-ports monitors series come with mountable size and can be
easily mounted on the rack for space saving and working efficiently. This
flexible solution that accommodates multiple digital video displays is
especially suitable for applications of public broadcasting such as:
◆Presentations ◆Exhibits
◆Demonstrations ◆Trade shows
◆Monitor testing and burn-in ◆Business meetings
◆News ◆stock tickers
◆airline/train/bus schedule ◆Retail stores

Installation
WARNING
●Prior to the installation, ensure to power off all devices that will be connected
to this system.
●Ensure that all devices you will connect are properly grounded.
●Place cables away from fluorescent lights, air conditioners, and machines
that are likely to generate electrical noise.
One piece of DVI male-to-male cable is required to connect from a video
source to the Video Splitter Input (SOURCE). Multiple monitors or TVs
should be connected to the Video Splitter's output ports as the following
figures shown.
For the model with built-in audio port, plug a set of audio jack from the
speaker to the Splitter’s audio port.
For DS-4x211 series with audio over DVI combination support, both audio
and video signals can be outputted by using a DVI-to-HDMI adapter that
combines digital video (DVI) and digital audio into HDMI to seamlessly
integrate into your modern home theater or computer systems. The
connection is as simple as connecting the optional DVI-to-HDMI
adapter(s) to the output side of the splitter, and then connect the HDMI
display or projector to the HDMI output of the DVI-to-HDMI adapter. The
adapter will convert the digital audio onto the digital video signal to
generate the HDMI signal. But please note: Not all hardware and not all
cables are supporting the audio over DVI feature!
Turn on your video source only after you've made all the connections.

NOTE: At least one monitor connection to the splitter unit is required when
powering on the source device.
NOTE: The splitter unit is required to connect to the computer before the
computer powered on.
NOTE: The splitter unit is HDCP compliant and requires using a HDCP-
compliant display when it is connecting to the HDCP video source.
NOTE: Each output port on the Unit is required to apply the same connection
pattern whenever a DVI-to-HDMI (or HDMI-to-DVI) adapter is used for
HDMI (or DVI) signal conversion between the Unit and the HDMI (or
DVI) display. The mixed (HDMI and DVI) output connections (possible
examples as the following figures shown) may cause signal
degradation. For instance, a 4-Port Unit with one output connection to
a DVI monitor and another output connection to a HDMI monitor via a
HDMI-to-DVI adapter or cable, the output signal could be distorted.
Signal degradation, harmful interference, or equipment malfunction
are less likely to occur if absolute connection consistency is used.
The example of mixed connection pattern should not be used, because of
possible disturbances.

Blu-ray Ready
The Splitter Unit is able to support high definition video such as DVD or Blu-
ray and multi-channel audio, and carry the best signal from source to displays;
the high bandwidth allows for the transmission of large amounts of information
at a very high rate of speed.
Blu-ray uses a blue-violet laser to read and write data, while current
optical disc technologies such as DVD, DVD±R, DVD±RW, and DVD-
RAM rely on a red laser to read and write data. Despite the different type
of lasers used, Blu-ray uses a blue-violet laser (405nm) that it has a
shorter wavelength than a red laser (650nm), which makes it possible to
focus the laser spot with even greater precision. This allows data to be
packed more tightly and stored in less space, so it's possible to fit more
data on the disc even though it's the same size as a CD/DVD.
Operation
The quality of the output signal will depend largely upon the quality of video
source, cable and display device used. Low quality cables degrade output
signal causing elevated noise levels. Please use the proper cable and make
sure the display device is capable of handling the resolution and refresh
rate selected. Interference from nearby electrical devices can have an
adverse effect on signal quality as well.

NOTE: Please connect at least one display device to the splitter before you
powering on the source Unit.

Troubleshooting
Symptom Possible Cause Solution
Video does not display
on some ports
DVI specification of
the source devices
doesn’t match the DVI
specification of DVI
cable and/or the DVI
display device
There are three DVI standards: DVI-
I, DVI-D, and DVI-A. Make sure
that DVI specifications of the
source devices, cables, and
monitors all match.
NOTE: Some monitors are able to
support multiple DVI signals.
Check if the splitter unit has been
connected to the source computer
before the computer powered on
Erratic. behavior Splitter may not
receive enough power
Please check the power adapter
attached to the splitter if it matches
the system specifications, and if it
is functioning properly.
Not receiving picture
or sound
Wrong installation
process
The video splitter requires at least
one monitor connection before
powering on the source device.
The signal source
may require the
display device that is
HDCP compliant.
Check if the display monitor is HDCP
compliant.
HDCP prevents the transfer of
digital content to unauthorized
HDMI devices.
The display monitor is
added to the unit by
hot-plug, but the
video source may not
support hot-plug.
Check if the video source supports
hot-plug.
If it doesn’t, shut down the source
device and reboot it again.
The attached devices
are not well
connected.
Check if you have connected your
components correctly
