4.0 CONNECTING THE HARDWARE
Please study the images below to become familiar with the location of the
controls, status LEDs, signal input, signal outputs, and the power input.
DVI-5312b DVI 1x2 Splitter / Repeater
DVI-5314b DVI 1x4 Splitter / Repeater

-5-
The DVI-5312b and DVI-5314b splitters are functionally identical with the
exception of the number of outputs. Both units have a single DVI-D input and a
+5 VDC power input jack. These connections, as well as the output connectors,
are located on the rear panel.
4.1 Input / Output Connections
Connect a DVI-D or HDMI compliant input signal from a suitable source device
to the DVI Input Port. Next connect the output devices (typically displays) to the
DVI Output Ports. Make certain that all cables are securely plugged in on both
ends. Always use high quality cables, as short a length as possible, to ensure
the best results. Do not exceed the recommended cable lengths indicated in
this User Guide.
4.2 Connecting the Power
This product is shipped with an External AC Power Adapter that converts 100-240
VAC at 50/60Hz to +5 VDC with 2.0A output current. Connect the output cable
from the AC Power Adapter to the locking receptacle on the rear panel. Take care
to insert, then twist the connector a quarter turn in the clockwise direction. There
is no power switch on these units. The units will turn ON as soon as the supplied
AC Power Adapter is connected to a live AC power receptacle.
5.0 OPERATING THE UNIT
To use the DVI-5312b and DVI-5314b splitters, rst connect a DVI-D or a HDMI-
DVI cable from the DVI or HDMI source device to the input of the splitter. Next,
connect the outputs of the splitter to their destination devices (typically displays or
projectors). Take care to ensure the cable quality and lengths are consistent with
the recommendations provided herein.
Once the input and output cables and External AC Power Adapter are connected,
plug the power adapter into a live AC power receptacle and the splitter will begin
to function. A Power LED on the front of the unit will conrm power is present.
Other than connecting cables and applying power, there are no other set-up steps
required with the exception of setting the EDID selector switch on the front panel.
Note: Proper operation of this product depends on the use of high quality cables.
DVIGear’s Super High Resolution (SHR™) DVI or HDMI cables provide low loss, low jitter,
high bandwidth signal handling and are the recommended cables for use with this product.

5.1 EDID Management
EDID (Extended Display Identication Data) is a collection of data cached inside
all modern displays that describes the unit’s capabilities. The EDID information
is dened by a standard published by the VESA (Video Electronics Standards
Association) and includes information such as the manufacture’s name, model
number, supported resolutions and video timings, supported audio formats, color
space, etc. During boot-up, a source device must be able to read the EDID of the
connected display. When using a splitter, it is necessary that the EDID from one
of the connected displays is passed back to the source device. The EDID value
used is critical to the performance of the system as a whole.
On the front of the unit there is an EDID selection switch. This switch controls
what EDID information the splitter will report to the source device. The EDID
information provided to the source can either be EDID from one of the connected
displays (AUTO EDID Mode) or from an on-board memory chip that contains a
library of the most commonly used resolutions (INT EDID Mode). These internally
stored resolutions are listed in the table below.
Resolution Vertical Rate
(Hz) Scan Format
480p 720x480 60 Progressive
576p 720x576 50 Progressive
720p 1280x720 50,60 Progressive
1080i 1920x1080 50,60 Interlaced
1080p 1920x1080 50,60 Progressive
VGA 640x480 60 Progressive
SVGA 800x600 60 Progressive
XGA 1024x768 60 Progressive
SXGA 1280x1024 60 Progressive
UXGA 1600x1200 60 Progressive
WXGA 1280x800 60 Progressive
WXGA+ 1440x900 60 Progressive
WSXGA 1680x1050 60 Progressive
WUXGA 1920x1200 60 Progressive
When set to the AUTO position, the splitter will automatically discover and apply
the EDID based on a predetermined selection hierarchy as follows:
HDMI v1.3 HDMI v1.2 DVI
When the splitter powers ON, it automatically begins the EDID discovery process
by sequentially scanning the connected displays on all outputs, starting with

-7-
Output #1, then Output #2, etc. The splitter will select the EDID from the rst
HDMI v1.3 compatible display that it nds. If no such displays are connected
to the splitter, it will select the rst EDID that it nds from a connected display
that is HDMI v1.2 compatible. If no such displays are found, it will select the rst
EDID that it nds from a connected DVI display. The selected EDID information
becomes the “reference EDID” and is stored in the splitter’s memory. When the
connected source device boots up it will read the EDID stored in the splitter’s
memory and react as if it were connected directly to the display that provided it.
For example, if the display connected to Output #1 is a DVI monitor, or if no
display is connected, the splitter will search for EDID information from Output
#2, then Output #3, and Output #4, until it nds a display with valid HDMI EDID
information. In the event none of the outputs has an HDMI display connected, the
splitter will use the EDID of the rst DVI display that is connected as the “reference
EDID” for the source device.
The default factory setting for the EDID switch setting is AUTO. This setting
works best for most applications. If one or more displays do not operate properly
such that there is no image, or the image is too large or too small, then reset
the EDID switch to the INT position. After changing the EDID switch setting it is
necessary to cycle the power to the splitter (turn OFF, then turn ON) in order to
force the source and the displays to re-sync the EDID information. With some
sources devices (PCs) it may be necessary to re-boot in order to recognize the
new EDID information.
5.2 LED Operation
There are two types of status LEDs that indicate the operation of the splitter:
Input LEDs and Output LEDs.
INPUT LEDs: Power, HDMI/DVI, HDCP, and SYNC
Power: LED illuminates red when the External AC Power Supply is
connected to both the unit and a live AC power outlet.
HDMI/DVI: LED illuminates green when the source is HDMI. The LED is
turned off if the source is DVI.
HDCP: (High-bandwidth Digital Content Protection) LED is
illuminated green if the input signal is HDCP encrypted.
SYNC: LED illuminates green if the source provides an active signal.
OUTPUT LEDs: Are identied with a number from 1 to 4 depending upon the
type of splitter. The numbers correspond to the splitter’s outputs. These LEDs will
be illuminated green if the output of the splitter is connected to a working display
or other type of output device.

6.0 TROUBLESHOOTING
In the event of problems, rst make certain that the input and output cables are
connected securely and are of the highest possible quality.
Note: Use of low quality cables can seriously degrade the performance of this
product. To ensure optimal performance and maximum cable distance, use
premium quality cables such as DVIGear’s Super High Resolution (SHR™) Series
or equivalent.
Next, check the Power LED to make certain that the Splitter is receiving power.
It should be fully illuminated and not ickering or intermittently going on and off.
Intermittent operation may indicate a problem with the AC Power Adapter or too
low AC voltage being applied to the AC Power Adapter input.
If the input signal is HDCP encrypted, check to ensure that the connected
display(s) or other output device(s) are HDCP compatible. Also check to ensure
that the source device supports HDCP Repeater functionality.
Note: For troubleshooting HDCP links, it can be very helpful to have a test
generator that can turn HDCP On and Off manually. DVIGear’s DVI-7050a HDMI
Test Generator is a good solution for this requirement.
Some Blu-ray players and DVD players will provide non-HDCP encrypted
content briey on power-up (e.g. splash screen). Also many DVDs and Blu-ray
players intentionally do not use HDCP encryption on the previews that precede
the main feature; this can provide a helpful indication when diagnosing HDCP
related problems.
Should the problem persist after trying the above suggestions, please contact
your dealer for additional assistance. Should the dealer’s technical personnel be
unable to assist you, please contact DVIGear via telephone at 1.888.463.9927
