Introduction:
The Lumagen HDMI 1.4 CAT-cable extender is designed to allow
more reliable real-world performance with longer cable lengths than
competing products. Some key features are:
-Maximum pixel clock rate up to 300 MHz (3 Gbps per channel)
-Active signal buffering for video and control (DDC) signals, at
both the transmitter and receiver, maximizes video, EDID, and
HDCP-encryption-key, signal integrity.
-Programmable cable equalization at both transmitter and
receiver provides lower cable jitter, and therefore longer cable
lengths, than dynamic-cable-equalization solutions.
-Power supplies at both transmitter and receiver eliminate power-
supply-current induced cable voltage-drop. This improves signal
integrity.
-Using CAT6 FTP or STP, with 24 AWG HDMI, cables supports
1080p60 for a total distance of over 60 meters, with up to 30
meters of HDMI 1.3 22 AWG HDMI cable plus up to 30 meters
of CAT6 STP cable, under nominal conditions.
-Supports all HDMI 1.4 3D formats and the HDMI 1.4 Audio-
Return-Channel (ARC). NOTICE:
Use of shielded CAT5e FTP or CAT6 FTP cable, or better, is
required to conform to electromagnetic interference regulations.
The Lumagen HDMI-CAT6 cable extender uses a HDMI repeater
chip in both the transmitter and receiver. Typically other products do
not have a repeater chip in the “transmitter.” Solutions lacking an
active video buffer in the transmitter cause discontinuities in the
impedance of the transmission line, reducing maximum cable length.
Both transmitter and receiver support long input cables. For example,
a system could have a 30-meter 22-AWG HDMI 1.3 cable driving the
transmitter, a 30-meter CAT6 FTP cable-pair to the receiver, and a 3-
meter HDMI cable from the receiver to the display/projector.
The transmitter and receiver have “static” input cable equalization
(Input-EQ). The Input-EQ for each is selected manually using an 8-
position rotary switch, based on its input cable length. Static cable-
EQ has less signal jitter than dynamic-cable-EQ solutions. This
translates into the ability to support longer cable lengths.

When long cables, or cable extenders, have issues in a given system,
Lumagen has found that it is often due to problems with the DDC
signals. Since the DDC signals are needed for HDCP and EDID
communication, Lumagen uses active DDC buffers in both the
transmitter and receiver. Unfortunately, many other HDMI extender
manufacturers do not buffer these signals in their products. The three
cables involved (input HDMI, CAT, output HDMI) all contribute
cable capacitance losses. By having DDC buffers in both the
transmitter and receiver, losses for each of the three cables can be
isolated and corrected.
There is a separate power supply for the transmitter and the receiver.
This eliminates voltage-drop caused by powering the repeater chip
through the CAT cable. This is important for DDC signal integrity.
Lumagen has measured significant voltage drop in other products that
power their repeater chip through the CAT cable, which reduces their
signal integrity. Separate power supplies eliminate this issue.
Installation Instructions:
Lumagen specifies the use of shielded CAT5e FTP/STP or CAT6
FTP/STP cable to meet EMI regulations. Non-shielded (UTP) cable
will function, but will not meet EMI regulations. Another advantage
of FTP/STP cable is that it is less susceptible to crosstalk from other
cables in a cable-bundle environment. CAT6 FTP/STP cable supports
longer reliable cable lengths compared to CAT5e FTP/STP cable
because its electrical characteristics are better suited for video
applications.

Connection order is important so ground signals in the CAT control
cable are connected first to reduce the chance that ground loop
current will damage equipment. Lumagen recommends connecting
cables in the following order:
-Insert the supplied 5-VDC power-supply into the HDMI-CAT6
Receiver’s 5-VDC jack, twisting it to make sure it seats all the way
into the case. Plug the power supply into the wall outlet.
-Connect the control CAT cable and then the video CAT cable into
the HDMI-CAT6 receiver.
-Connect the HDMI cable from the HDMI-CAT6 receiver to the
projector/display.
-Insert the supplied 5-VDC power-supply into the HDMI-CAT6
Transmitter’s 5-VDC jack, twisting it to make sure it seats all the
way into the case. Plug the power supply into the wall outlet.
-Connect the CAT cable for control and then the CAT cable for
video to their respective output on the HDMI-CAT6 Transmitter.
-Connect the HDMI cable from the source to the HDMI-CAT6
transmitter.
-Turn the system on.
Caution:
Be careful to not cross-wire the control and video cables as it may
damage the HDMI-CAT6 extender.
Caution:
Ground loops are common even in well-designed systems -- even
with power conditioners. Power conditioners do not prevent the most
common ground loop issues, which are related to the ground prong
on equipment with three prong power cords, and the difference in the
case ground voltage potential between equipment. Given the longer
distance involved, ground loops are generally worse for the source to
display/projector connection. To help prevent damage, audio and
video cables should be connected before power. This allows the
ground wires of the audio/video cables to handle any ground loop
current rather than the audio and video signals themselves.

Status Indicator Lights:
There are two light-emitting-diode (LED) indicator lights on the
transmitter and on the receiver. These show the connection status as
described below:
-ACTIVE: On if the external 5-VDC power is supplied, and HDMI
“Standby Power” is active.
-VIDEO: On if the ACTIVE light is on, and the video input signals
are actively driven.
All the indicators on both the transmitter and receiver must be
illuminated for the HDMI-CAT6 extender to pass video/audio.
However, having all the indicators illuminated does not guarantee
that video/audio can be passed, or that the desired resolution can be
achieved for the system as configured. The lights indicate that power
is supplied, that the source’s “standby power” is active, and that the
video input signals are being driven, and not that video is being
correctly received.
Input Equalization Selection:
The transmitter and receiver each have an input-equalization (Input-
EQ) rotary switch with settings from 0 (no Input-EQ) to 7 (maximum
Input-EQ) to select the cable equalization for their respective input
cable. For short input cables, set input-EQ to 0. Input-EQ settings
range from 0 –2 for up to 5 meters, 1 –4 for 5 to 10 meters, and 2 – 7
for = 10 meters. NOTE:
The Transmitter’s input equalization switch is set based on the
length of its input HDMI cable. The Receiver’s input equalization
switch is set based on the length of its input CAT cable.
For best performance multiple switch settings should be tested and
the average of the working settings should be used.
After the transmitter and receiver Input-EQ settings have been
selected, power down the system and then power on normally to test
that the video signal “locks” at power on. Acquiring signal “lock” is
harder than maintaining “lock.” A setting that works while changing
Input-EQ settings may not “lock” during power-on. While unlikely, if
this occurs, try other settings and test for power-on signal “lock.”

Setup Tips and Trouble Shooting:
-When installing new CAT cable, always install CAT6 FTP cables
(i.e. shielded), or better, for use with HDMI-CAT extenders.
-Avoid bundling the high-frequency video cables with LAN and
other digital cables. Using CAT6 FTP cables reduces the potential
for crosstalk between cables.
-Cable type, source-device clock-jitter, sink-device jitter-sensitivity,
intra-cable crosstalk, inter-cable crosstalk, cable bundling, and
ground loops, determine, and limit, maximum reliable cable length.
-The Transmitter’s input equalization switch is set based on the
length of its input HDMI cable. The Receiver’s input equalization
switch is set based on the length of its input CAT cable.
-If the system is properly connected with quality cables of an
appropriate length, and equipment is turned on, if no video is seen,
the likely cause is either the transmitter or receiver Input-EQ is not
properly set for the given cable type and cable length.
-HDMI audio is more sensitive to cable jitter than video. So, the
maximum cable length may be reduced if audio is being used.
Specifications:
-Maximum pixel clock rate: 300 MHz (3 GHz bit rate per channel),
which support up to 1080p120, or 1080p60 with 16-bit 4:4:4
-Maximum video rate using CAT6 STP cable, or for the transmitter
input using 24 AWG HDMI cable, for ideal conditions is:
For 1080p60 with 12-bit 4:2:2, or 8-bit 4:4:4: 30 meters
For 1080p75 with 12-bit 4:2:2, or 8-bit 4:4:4: 25 meters
For 1080p120 with 12-bit 4:2:2, or 8-bit 4:4:4: TBD
-Maximum total source to sink cable length (HDMI, CAT, HDMI)
using for nominal conditions is 62 meters at 1080p60 12-bit 4:2:2,
or 8-bit 4:4:4 video, using 30m of HDMI 1.3 and 30m of CAT6
FTP, under nominal conditions.
-Maximum distance may be reduced if audio is used since HDMI
audio is more sensitive to cable induced jitter than video
-Supports all HDMI 1.4 3D formats and the HDMI 1.4 Audio-
Return-Channel (ARC).
-Power: Transmitter = 2.5 Watts, Receiver = 2.5 Watts
