The Gefen 1:5 Splitter For HDMI Over CAT-5

The Gefen 1:5 HDMI Over CAT5 Distribution Amplifier allows you to distribute HDMI video to 4 remote HDTV displays and to 1 local HDTV displays via inexpensive and standard CAT5 cables.

How It Works

Simply plug your video source into the Gefen 1:5 HDMI Over CAT5 D.A. Sender unit, then run an HDMI cable to your local HDTV displays. Then connect your CAT5 cables to 1:5 HDMI Over CAT5 D.A. Sender unit, and finally connect a pair of CAT5 cables to each of the 4 HDMI CAT5 D.A. Extreme Receivers at remote HDTV display.

Note: CAT5 cable extensions may be up to 300 feet (1080i) or 150 ft (1080p).

READ THESE NOTES BEFORE INSTALLING OR OPERATING THE 1:5 SPLITTER FOR HDMI OVER CAT-5

1:5 Splitter For HDMI Over CAT-5 will split the HDMI signal to 5 HDMI • outputs. 4 of these outputs can be sent over CAT-5, CAT-5e or CAT-6 cables to remote locations while the last output can be used for local use.

An short HDMI jumper cable (4 are included) must be connected from each of the lower board HDMI outputs to each of the upper board HDMI inputs to use the extension capabilities of the 1:5 Splitter For HDMI Over CAT-5.

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.

If EMI is present anywhere near the CAT-5, CAT-5e or CAT-6 video cable • runs, it may be necessary to use shielded cable. This is to prevent possible interference from degrading the video signal. Using shielded cable, however, will reduce the maximum distance that the cable can be run.

Extensions under 130 feet can use Auto EQ (which is on by default). • Extensions over 130 feet will require you to manually EQ your signal (see page 10).

Each cable run must be one continuous run from one end to the other. No • splices or use of punch down blocks.

High quality CAT-6 cabling should be used for maximum performance.

Do not use stranded or low/no skew cabling. Solid core cabling should be used for maximum performance.

How to Connect the 1:5 Splitter For HDMI Over CAT-5

Connect the HDMI source device to the 1:5 Splitter For HDMI Over CAT-5 1. sender unit using the supplied HDMI cable.

Connect up to 4 of the HDMI outputs to the HDMI jumper inputs using the 2. supplied short HDMI jumper cables. The fifth port can be used for local HDMI output to a display. Alternately, any or all output ports can be used to route HDMI to local displays, bypassing the HDMI extension feature.

For each HDMI extension, connect a pair of user supplied CAT-5, CAT-5e or 3. CAT6 cables between an open pair of RJ-45 extension ports on the sender and the pair of RJ-45 ports on a receiver.

NOTE: When field terminating CAT cable, please adhere to the TIA/EIA-568-B specification. Please see page 11 for details.

Connect a HDMI capable display to the receiver using a user supplied HDMI 4. cable.

Connect the included 24V DC power adapter to the sending unit and one of 5. the included 5V DC power adapters to each of the receivers.

Power on the displays first and then the source device.6.

NOTE: Video may not immediately appear. If this is the case, please refer to the next section for instructions on how to change EDID modes and adjust equalization.

EDID (Extended Display Identification Data) contains information on the resolution and general capabilities of a display device. This information is used by the source device to output a compatible signal that the display can accept. This information can even be used by some source devices to limit the output of resolutions and features that the display is not capable of accepting. In single source and single device setup, EDID can effectively ensure compatibility with display and source. The 1:5 Splitter For HDMI Over CAT-5 replicates a single HDMI input from a source to up to 5 HDMI capable devices. However, since the source device can only output one type of audio and video signal (resolution, features, number of audio channels, audio format, etc.) based on the EDID it receives, all connected HDMI devices must have common audio and video capabilities for successful replication to occur.

The source of the EDID can be selected using the EDID mode feature. There are two sources from which the EDID can be polled and then transferred back to the source device. The External mode uses the EDID from the display connected to the first HDMI output port. The Internal mode will use and built-in EDID that is stored in the unit. The Internal EDID mode supports resolutions of up to 1080p and includes common audio features.

How to Change EDID Modes

Locate the EDID Mode Switch on the rear panel of the 1:5 Splitter For HDMI 1. Over CAT-5 sender unit.

Note the switch's current position and change the EDID mode to either INT 2. (Internal) or EXT (External) by toggling the switch.

Press the reset button on the front panel to reset the connection to the 3. source device so that it can re-detect the new EDID change.

Each 1:5 Splitter For HDMI Over CAT-5 receiver contains a Dip Switch bank located on the underside of the unit. This bank of 4 Dip Switches are covered with a piece of silver metallic tape. These Dip Switches will modify boost settings and change the equalization mode.

EQUALIZATION MODES

Dip Switch 1 is used to select the equalization mode. There are 2 EQ modes to select from. Auto Equalization (Dip Switch 1 = Off, default) will automatically attempt to equalization the incoming signal and eliminate and digital noise that may occur due to variances in cable skew. Manual Equalization (Dip Switch 1 = ON) will allow the user to manually EQ the signal using the Trim Pot located on the front panel of the receiver. By default, Auto Equalization is set and is effective for CAT cable runs of up to 130 feet. Distances greater than 130 feet should be manually equalized. Use the table below for quick reference of the EQ Dip Switch modes.

Receiver Auto EQ Dip Switch Settings
Setting Switch 1 Switch 2
Manual EQ ON Not Used
Auto EQ (Default) OFF Not Used

BOOST MODES

Dip Switches 3 and 4 are used to specify the boost strength of the signal from the 1:5 Splitter For HDMI Over CAT-5 sender. This feature will boost the signal when long distances of cable are used and will also help the signal reach the receiver when low quality cable is used. There are not set distance rules in regards to this setting (due to the variances in cable quality), so it is recommended that the user try all settings, starting with no boost, when troubleshooting issues. Please refer to the table below for the 4 different Dip Switch combinations.

Receiver Boost Dip Switch Settings
Setting Switch 3 Switch	tch 4
No Boost (Default) OFF OFF
Medium Boost OFF ON
High Boost ON OFF
Very Low Boost ON ON
