OPERATION NOTES  
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.  
HDMI 1.2 Compliant.  
HDCP Compliant.

CONNECTING AND OPERATING THE  
1:5 SPLITTER FOR HDMI OVER CAT-5  
How to Connect the 1:5 Splitter For HDMI Over CAT-5  
1. Connect the HDMI source device to the 1:5 Splitter For HDMI Over CAT-5  
sender unit using the supplied HDMI cable.  
2. Connect up to 4 of the HDMI outputs to the HDMI jumper inputs using the  
supplied short HDMI jumper cables. The fth 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.  
3. For each HDMI extension, connect a pair of user supplied CAT-5, CAT-5e or  
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 eld terminating CAT cable, please adhere to the TIA/EIA-  
568-B specication. Please see page 11 for details.  
4. Connect a HDMI capable display to the receiver using a user supplied HDMI  
cable.  
5. Connect the included 24V DC power adapter to the sending unit and one of  
the included 5V DC power adapters to each of the receivers.  
6. Power on the displays rst and then the source device.  
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 MODES  
EDID (Extended Display Identication 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 rst 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  
1. Locate the EDID Mode Switch on the rear panel of the 1:5 Splitter For HDMI  
Over CAT-5 sender unit.  
2. Note the switch’s current position and change the EDID mode to either INT  
(Internal) or EXT (External) by toggling the switch.  
3. Press the reset button on the front panel to reset the connection to the  
source device so that it can re-detect the new EDID change.

EQUALIZATION & BOOST SETTINGS  
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.

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.
