The Gefen 4x4 HDMI Over CAT5 Matrix
The Gefen 4x4 HDMI CAT5 Matrix offers unprecedented fl exibility and conve-
nience by routing high defi nition audio/video from any of four HDMI video sources
to any of 4 remote displays over inexpensive, standard CAT5 cabling.
Each remote display has a control box that allows the viewer to select any of the
4 video sources and control that source via an IR remote control as if the viewer
was standing in the room where the source originates.
Full High-Resolution HDTV signals are supported up to a resolution of 1080p at a
maximum distance of 150 feet and 1080i resolutions can be extended up to 300
feet. The Gefen 4x4 HDMI CAT5 Matrix works with HD-DVD players, TiVo systems, HT PCs, and satellite set-top boxes that connect to an HDMI display. Every
source is accessible at all times by any display by selecting it with an IR remote.
How It Works
You simply connect up to 4 local video sources to the CAT5-Matrix’s inputs. Then
run each of your CAT5 cables from the Matrix to the destination displays. At each
remote display, terminate the CAT5 cable run with a HDMI CAT5-MS Receiver
device. Connect each Receiver to a display and you’re all set.

READ THESE NOTES BEFORE INSTALLING OR
OPERATING THE 4X4 HDMI OVER CAT5 MATRIX
• To use the extender functionality of the 4x4 HDMI Over CAT5 Matrix the
supplied 1 foot HDMI jumper cables must be used to connect the HDMI
output ports to the HDMI extension input ports. Please see page 11 for
details
• Use two industry standard CAT-5, CAT-5e or CAT-6 cables to operate each
of the 4x4 HDMI Over CAT5 Receivers. Gefen recommends CAT-6 cabling
for maximum performance.
• For 1080i video, maximum extension is 300 feet (91 meters).
• For 1080p video, maximum extension is 150 feet (45 meters).
• IR repeater functionality is only from the receiving unit to the sending unit. IR
data cannot be transmitted from the sending unit to the receiving unit.
• When a display connects to a source being viewed by other displays, a short
fl ash may appear momentarily on the displays already viewing that source.
This is normal operation as new handshakes for HDCP are being made.
• Local displays that are not using the extension functionality of the 4x4 HDMI
Over CAT5 Matrix can only switch their viewing source via the RS-232 Serial
Control Interface. Please see page 18 for a list of commands and instructions.

Auto Equalization & Boost Setting
Auto equalization is enabled by default. This setting will compensate for variances
in cable skew and will help eliminate the video noise that is associated with it. This
feature will work reliably up to 130ft. Longer CA T-5e runs should have this feature
disabled. It is important to understand that the Boost Setting and Equalization are
used in conjunction with each other. The Auto-EQ feature will only function when the
unit has no boost applied.
To manually equalize the video signal, turn Dip Switch 1 to the ON position. This will
disable the auto equalization function and will allow the user to manually equalize the
signal. From here, the Boost Settings and Equalization can be manipulated to tune-in

EDID MANAGEMENT FEATURES
18
EDID. What is it and what is it used for?
Under normal circumstances, a 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 4x4 HDMI over CAT5 Matrix?
The 4x4 Matrix is complex piece of technology that replicates and switches
between multiple inputs and outputs. Each connected source device will require
one EDID to read. EDID management is carefully handled by 4x4 HDMI over
CAT5 Matrix to provide a single EDID for each source to read.
What options do I have to manage the EDID in the 4x4 HDMI over CAT5
Matrix?
First, it is important to note that each source device can only output one video/
audio signal type. This includes resolutions and timings. When multiple devices/
displays are used, such as with the 4x4 HDMI over CAT5 Matrix, 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
4x4 HDMI over CAT5 Matrix, 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 4x4 HDMI over CAT5
Matrix 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 4x4 HDMI over CAT5 Matrix?
There is an bank of 8 DIP switches located on the main-baord inside of the
4x4 HDMI over CAT5 Matrix. DIP switches 1, 2, 5, and 7 are used in different
combinations to manage the EDID modes.
TIP: EDID modes and IR code channels can also be managed via the RS-232
serial communications port. For this to work, all DIP switches must be in the OFF
position. This is the factory default setting. If you wish to use this feature, please
do not open the unit. See page 12 for more information on the RS-232 serial
communication features.
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 and on each
side of the RS-232 serial communications port. Carefully slide the unit apart.

RS-232 SERIAL COMMUNICATION
What features are available via the RS-232 serial communications port?
The 4x4 Matrix for HDMI can accept commands through the RS-232 serial
communications port located on the rear panel. The current RS-232 control
features are:
• Switching/routing of inputs to outputs without the RMT-16IR remote control.
• Switch EDID management modes without opening the unit to physically
modify DIP switches.
• Change IR code channel without opening the unit to physically modify DIP
switches. (The IR code channel will still need to be manually modifi ed on the
RMT-16IR remote control to match the code channel.)
How do I use these features?
These features were initially intended for utilization by custom installers in
automated setups. However, these features can be tested by using any Windows
PC with the Hyperterminal program.
What pins are used for communication with the 4x4 Matrix for HDMI?
Only pins 2 (Receive), 3 (Transmit), and 5 (Ground) are used for communication.
A null-modem adapter should not be used with this product.
