Instruction Manual

Installation

Preparing Your Site

1. Determine where the local video source (i.e. computer, Blu-ray Player) will be

located and set up the device.

2. Determine where the remote display will be located and place/ mount the

display appropriately.

NOTE: This HDMI® extender kit features Power over cable, allowing both the

Transmitter and Receiver to be powered from a single power source that can be

connected at either end of the connection. Please ensure that either the Transmitter

or the Receiver Unit is situated near an available AC electrical outlet. Make sure all

devices are turned o before beginning installation.

Hardware Installation

1. Install Transmitter Unit

a) Position the Transmitter Unit near the video source (i.e. Computer, Blu-ray Player).

b) Connect an HDMI® cable from the video source device (i.e. computer, Blu-ray

Player) to the “HDMI® IN” on the Transmitter Unit.

c) (Optional) If you’ve chosen to power the kit from the Transmitter side, connect

the provided power supply.

2. Install RJ45 terminated Cat5e/6 Ethernet Cables

a) Connect an RJ45 terminated Cat5e/6 Ethernet cable (not included) to the LINK

OUT A (RJ-45 connector) on the Transmitter unit.

b) Connect another RJ45 terminated Cat5e/6 Ethernet cable (not included) to the

LINK OUT B (RJ-45 connector) on the Transmitter unit.

NOTE:

If you are using surface cabling, ensure you have enough Category 5e unshielded

twisted pair (UTP) network cabling to connect the Host Unit to the Remote Unit’s

location, and that each end is terminated with a RJ45 connector. The cabling should

not go through any networking equipment (i.e. router, switch).

If you are using premises cabling, ensure that the Category 5 unshielded twisted pair

(UTP) network cabling between the Host Unit and theRemote Unit has been properly

terminated in a wall outlet in each location and there is a patch cable long enough

to connect the Remote Unit and the Host Unit to their respective outlets. The cabling

should not go through any networking equipment (i.e. router, switch).

Instruction Manual

c) Connect the other end of the Cat5e/6 cable (from LINK OUT A) to the LINK IN A

(RJ-45 connector) on the Receiver Unit.

d) Connect the other end of the Cat5e/6 cable (from LINK OUT B) to the LINK IN B

(RJ-45 connector) on the Receiver Unit.

NOTE: If using Cat6 cables, extension distance is limited to 40m (130 ft)

3. Install Receiver Unit

a) Position the Receiver Unit near the video display (i.e. television, projector).

b) Connect the video source to the HDMI® OUT on the Receiver Unit using an

HDMI® cable.

c) (Optional) If you’ve chosen to power the kit from the Receiver side, connect the

provided power supply.

4. Your source video image will now appear on the remote video display.

Operation

Video Adjustment (Receiver Unit Only)

This function allows adjustments in sharpness of the video image for better clarity.

If necessary, adjust the EQ Selector at the Receiver Unit to compensate cable length.

Turn the EQ Selector one notch at one time and wait for 10~12 sec. For HDMI cable

length (Rx-to-monitor) less than 8 meters, the selector position is around 0~7 (depends

on video resolution). For HDMI cable length (Rx-to-monitor) greater than 8 meters,

the selector position is around 8, 9, A~F (depends on video resolution). For example,

if using a 1.8M (or 3.0M) HDMI cable, a CAT5 cable and a display with resolution of

Full HD (1920 x 1080), you may adjust video according to its CAT5 cable length as

following.

CAT5 Cable Length EQ Selector Position

0M~15M 0,1

15M~25M 1,2

25M~30M 2,3

EDID Conguration

In some cases display problems may occur due to incorrect EDID communication

between the display monitor and the unit or inappropriate EDID data programmed by

display manufactures. This EDID Copy feature allows the system either automatically

provide the necessary EDID to display or manually copy EDID from EDID compliant

displays via push button.

Auto EDID Conguration

The system can automatically read EDID from your display while two RJ-45 ports

(Video & Aux) are in connection.

Manual EDID Conguration (EDID Copy / EDID Ghost)

While using only one CATx cable, it is suggested applying EDID Copy rst.

Step 1. Use CATx cable for connection between Tx & Rx on Aux RJ-45 Jack. Apply

power to Receiver Unit.

Step 2. Connect the monitor (EDID compliant) to Video Out on the Receiver Unit

and power on the monitor.

Step 3. Press the button “EDID Copy” on Transmitter Unit and release the button

RIGHT AFTER the LED ashes green.

Step 4. The LED ashes green & red and then it lights blue indicating copy

successfully. Otherwise, if the LED ashes RED, it means that

a. The monitor is not properly connected.

b. The monitor is not powered on.

c. EDID data of the monitor is not applicable.

Try to repeat Step 3 to 4 again.

Instruction Manual
