INTRODUCTION

READ THESE NOTES BEFORE INSTALLING OR

OPERATING THE 1:8 HDMI CAT5 DA

• The 1:8 HDMI CAT5 DA unit is housed in a metal box for better RF shielding.

• An HDMI jumper cable (8 are included) must be connected from each of the

lower board outputs to each of the upper board inputs for proper extension

operation.

• The maximum cable extension is 300 feet (91 meters) for video resolutions of

1080i and below.

• The maximum cable extension is 150 feet (45 meters) for video resolutions of

1080p.

• Display information (EDID) from the display attached to the HDMI CAT5 DAR

receiver, which is then routed to HDMI output port 1 (lower board), will be sent back

to the source. Therefore, all other displays connected to the receivers at the remote

locations must be capable of accepting the timings and resolutions of the display

that is attached to HDMI output port 1. It is recommended that the display with the

lowest native resolution be connected to HDMI output port 1. This is to ensure that

a compatible video signal will be able to be displayed on all connected monitors.

• Shielded CAT6 with metal RJ-45 connectors is recommended to protect from

random ﬂ ashes caused by EMI.

• Extensions under 130 feet can use Auto EQ (which is on by default).

Extensions over this distance require use of manual EQ (see page 5).

• Each cable is recommended to be one continuous run from one end to the

other. While wall jacks and punch down blocks can be used, they may cause

degraded performance or unforeseen issues.

• Do not use stranded or low/no skew cabling. Solid-core cabling should be used

for maximum performance.

• HDMI / HDCP Compliant.

• The included power supply for the RECEIVER must be connected before the

connection of the CAT-5 cables. Once the power LED is active on the receiver

the CAT-5 cables can then be connected. Always follow this initialization

procedure on the RECEIVER if power has to been cycled due to a power

outage or for troubleshooting purposes.

How to Connect the 1:8 HDMI CAT5 DA

1. Connect the single HDMI source to the 1:8 HDMI CAT5 DA main HDMI input

using the supplied 6 foot HDMI cable.

2. Using the 8 supplied 1 foot HDMI jumper cables, connect each output on

the lower portion of the back panel to each of the HDMI inputs on the upper

portion of the 1:8 HDMI CAT5 DA.

3. Connect the remote displays (up to eight) to each of the HDMI CAT5 DAR

receivers using user supplied HDMI cables.

4. Connect the 5V DC power supply to each of the HDMI CAT5 DAR

Receivers.

NOTE: The included power supply for the RECEIVER must be connected before

the connection of the CAT-5 cables. Once the power LED is active on the receiver

the CAT-5 cables can then be connected. Always follow this initialization procedure

on the RECEIVER if power has to been cycled due to a power outage or for

troubleshooting purposes.

5. Connect each of the HDMI CAT5 DAR receivers (up to eight) to the 1:8

HDMI CAT5 DA sending unit using a pair of CAT-5, CAT-5e or CAT-6 cables.

NOTE: If ﬁ eld terminating network cable, please adhere to the TIA/EIA-568-B

standard. Please see page 8 for more information.

6. Connect the included 24V DC power supply to the 1:8 HDMI CAT5 DA.

7. Power on the displays.

8. Power on the source.

NOTE: If an image is not being shown on the display, please check all cabling for

proper connections and follow the steps outlined below and in the next section.

The 1:8 HDMI CAT5 DA and HDMI CAT5 DAR receivers have built-in auto

equalization that will automatically tune out any unwanted video noise. This

feature is reliable with premium cable runs up to a maximum of 130 feet. It may

be necessary to disable this feature if there is either no video being displayed on

initial start-up, there is video noise in the image, or the cable run exceeds 130

feet. First, verify that all the proper connections have been made and that all

devices are powered on before attempting to disable auto equalization. Please

follow the section on the next page to manually equalize the video signal.

1:8 HDMI CAT5 DA CONFIGURATION

CONNECTING AND OPERATING THE 1:8 HDMI CAT5 DA

MANUAL EQUALIZATION PROCEDURE

The HDMI CAT5 DAR receiver units have a set of dip switches located on the

underside of their casings. There is a piece of silver metallic tape that must be

removed to expose these dip switches. Each HDMI CAT5 DAR receiver carries

one bank of 4 dip switches. All dip switches on the HDMI CAT5 DAR receiving

units are used in this procedure. Dip switches 1 relates to the Auto Equalization

function, while dip switches 3 and 4 control the boost strength from the 1:8

HDMI CAT5 sending unit. By default, all dip switches on the HDMI CAT5 DAR

should be in the OFF position. To turn off auto equalization, turn dip switch 1 on

the receiving units to the ON position (Auto EQ off). With these settings, please

follow the steps below to equalize the picture.

1. Insert a small ﬂ at head tool into the trim pot on the receiver unit.

2. Turn the trim pot in a clockwise fashion until it comes to a stop. Do not force

the trim pot beyond this point. Doing so may render the trim pot useless.

3. Slowly turn the trim pot counter-clockwise in millimeter increments until the

image stabilizes and all video noise disappears.

4. Carefully remove the adjustment tool.

NOTE: If your cable run is beyond 130 feet, or the steps above do not produce

any video, it may be necessary to increase the boost from the sending unit. Use

the chart below to increase the senders boost strength by changing the HDMI

CAT5 DAR receiver’s dip switches. Once a new boost setting is set, repeat steps

1 through 4 from above. The required boost setting will largely be dependant

on the quality and length of cabling. Experiment with all boost settings until the

image stabilizes and all video noise has been eliminated.

EDID MANAGEMENT FEATURE

EDID. What is it and what is it used for?

Under normal circumstances, an source device (digital and analog) will require

information about a connected device/display to assess what resolutions

and features are available. The source can then cater its output to send

only resolutions and features that are compatible with the attached device/

display. This information is called EDID (Extended Display Information Data)

and a source device can only accept and read one EDID from a connected

device/display. Likewise, the source an only output one resolution for use by a

connected device/display.

Why is EDID so important with the 1:8 HDMI CAT5 DA?

The 1:8 HDMI CAT5 DA is complex piece of technology that replicates and

extends a single HDMI input. The single source device will require one EDID to

read. EDID management is carefully handled by 1:8 HDMI CAT5 DA to provide a

single EDID for each source to read.

What options do I have to manage the EDID in the 1:8 HDMI CAT5 DA?

First, it is important to note that the source device can only output one video/

audio signal type. This includes resolutions and timings. When multiple displays

are used, such as with the 1:8 HDMI CAT5 DA, it is important to use devices/

displays that have similar or compatible resolutions/features. This will ensure that

the single video/audio signal produced by the source device is accepted by all of

the connected output devices/displays.

The user has the option, through a combination of DIP switch settings within

the 1:8 HDMI CAT5 DA, to choose how the unit will manage the EDID from

multiple HDMI devices/displays. Therefore the user has some control over the

resolutions/features that the source devices will output. The 1:8 HDMI CAT5

DA has a multiple EDID management modes that will control how the EDID

information from multiple devices/displays are combined, ignored, and routed.

How do I change EDID modes in the 1:8 HDMI CAT5 DA?

There is an bank of 8 DIP switches located on the main-baord inside of the 1:8

HDMI CAT5 DA. DIP switches 1, 2, 5, and 7 are used in different combinations to

manage the EDID modes.

To access these DIP switches it will be required to open the unit. To do this,

remove all screws on the underside and side of the unit. Remove all HEX screws

on the rear panel. This includes the screws above each HDMI port. Carefully

slide the unit apart.
